Quit throwing away your hard earned cash for name brand toothpaste like a sucker!   Get the cleanest feeling teeth of your life with this homemade toothpaste recipe that actually tastes good

Toothpaste is something you can make easily with stuff you have at home, and flavor however you like.  Your family could be brushing their teeth for a YEAR for how much you're currently spending on one tube!*  Now how does that sound?

But Scooch, you say, I've tried homemade toothpaste, and it's tastes like. . . well, like baking soda!  Now, now, I understand your concerns - I've tried them all too.  Yuck!**  So I've decided to put an end to nasty homemade toothpaste with my own recipe, designed to bring you a new level of taste and freshness from that I think you're going to love!


*not including price of toothbrushes

** not intended to offend lovers of baking soda taste

Step 1: Ingredients


The basis of homemade toothpaste is baking soda and hydrogen peroxide.  Either one in huge doses can be dangerous, so DO NOT INGEST!

Sodium bicarbonate (baking soda) is a mild abrasive and has anti-bacterial properties. 

Hydrogen peroxide helps by break down bacterial films with its foaming action.  I used a 3% solution, but anything you can find at a local drug store should be ok.

Vegetable-base glycerin liquid lends a nice consistency and sweetness, but is completely optional.   You should be able to find this at a drug store, or specialty foods shop, but I got mine online from a soap-supply store.

I definitely recommend using some kind of flavoring.  It's totally optional, but adding a drop of peppermint oil will leave your mouth feeling super fresh.  Tea tree oil boosts the anti-bacterial properties and tastes good.  A few drops of cinnamon oil (my favorite!) will definitely spice things up.  Food-grade grape or bubble gum flavor oil may entice your kids to brush more regularly - just be sure to supervise them and make sure they're not ingesting it! 

Basic Ratio:

6 parts baking soda : 1 part vegetable based glycerin : 1 part hydrogen peroxide solution : flavor to taste


This makes a nice paste.  To make a smoother mix, reduce the soda.  To omit the glycerin, increase the peroxide.


Most over the counter hydrogen peroxide solutions are not suitable for ingestion.  Make sure to use supervision with children.

Hi Scooch,

I have been lambasted in a previous comment I made about hydrogen peroxide and the use of it. However, I have been using it without any ill efects for years. The only thing I would suggest on your ibble is to make use of 35% FOOD GRADE hydrogen peroxide, thinned down to 3.5 % with the purest water you can get. And yes, don't drink a bottle of it, but nigesting it in recomended dosage does absolutely no dammage. Just don't eat directly before or after as it could give you gas, and a lot of it lol.

To the person that told me before that I should not say this type of thing, try and google it and find out for your self, and see how many MD's recognise the benefits of hydrogen peroxide.

Thanks for this ibble scooch.

Com'on, guys. If you're an adult, why not just use baking soda on your toothbrush even though it doesn't taste so good! Sheez! You're only having it in your mouth for a couple of minutes while you brush your teeth. It isn't like you're sucking on the tail of a skunk! Get a grip and complain about something that really matters, i.e. endangered species being poached, pollution in our rivers that cause deformity in frogs and other animals that live in that water. Making a homemade toothpaste because just using baking soda doesn't taste good is not something I expected to find on a DIY site where people are practical and self-sufficient, or learning to be that way.

Rinsing your mouth with diluted hydrogen peroxide before using the baking soda on your toothbrush is a very easy way to include the peroxide part of the recipe. Just thought you'd like to know.
LisaAbejja says: Mar 2, 2012. 3:20 AM
hmmm probably because it is human to want nice things and why should we put up with a terrible taste if we don't want to?

Because we are adults and have our own freedom of choice we can decide to flavour stuff up to be palatable.
Pinky212 says: Mar 5, 2012. 2:10 AM
Please see my Feb. 22, 2011 post, and those of April 15, 2011.

I just noticed in the one written at 2:35 on the 15th, I made a big blunder. The last sentence of the fourth paragraph should have said "The doctor was NOT kidding."

I noticed now there are more typos, too. So much for my proofreading skills! LOL

You all have a great day!
jharper3 says: May 23, 2011. 12:07 PM
Actually, if you use ONLY baking soda and water, your breath will smell horrible because of it. My father used to do that. Also, I suggest adding mouthwash (sure, it may be an ingredient that is still out of your money, but all these ingredients still take money). The mouthwash also has the refreshing taste and good for your mouth!
love4pds says: Dec 12, 2011. 3:27 PM
except that fluoride is actually bad for your teeth and they already add it to most water supplies so I would suggest kindly to stay away from fluoride.

And on the same DIY source we have hundreds of candy recipes, Altoid tin refashions, knitting patterns, and other recipes, from laundry soap to home-made makeup. There's a lot of important-problem DIYs on here, but Instructables is about all sorts of DIY, not just 'useful' and 'important' ones.

This is a perfectly valid and wonderful Instructable. Personally, I gag doing what you suggested (straight baking soda), but don't want all the chemicals (and cost) of commercial toothpaste. So I'll be mixing up a batch of this to try, with my favorite cinnamon oil.

Question for the author: does the glycerin interfere with the cleaning properties of the toothpaste, as it's a sugar substance?
Idea Gal says: Apr 11, 2011. 6:33 AM
The thing is, glycerin prevents the tooth's natural ability to regenerate. Now consider that most commercial toothpastes contain glycerin and you understand how dentists stay in business.

I use plain baking soda with a few essential oils, and I haven't had a cavity in 10 years. It's a tooth powder instead of paste. It's not sweet like commercial toothpaste, but you get used to it over time. It's so cheap.

If you start kids on it when they're young, they readily accept it, and it's a fun game for them to make their "hand cup" while you shake in the powder and they "paint" their hand with their wet toothbrush before brushing. If they already have the taste for commercial supersweet pastes, getting them to switch is a challenge. Can be hard for an adult to adjust to non-sweetened, too, but you CAN adjust over time. Remember, it takes 21 days to form a habit, so stick with it for 3 weeks and you'll be used to it.

I've heard of mixing it with aloe vera gel or almond oil on the spot, but I'm in too much of a hurry in the morning - I use a peroxide essential oil mouthwash (commercial and costly - maybe I should rethink that), then brush with my baking soda + essential oils. Different oils do different things - some freshen, some remove plaque, some kill germs. Since you're putting them into your mouth, which is a mucous membrane that absorbs both good and bad ingredients readily, I recommend buying organic essential oils, if you can find them. I use Simplers essential oils - if you're only using the oils for toothpaste, they will last you a very long time. Don't leave them in sunlight - keep in your medicine cabinet. Here are some ideas: TEA TREE, LAVENDER, (germs), LEMON (plaque: smaaalll quantities, like 1-2 drops in 1 cup of soda so you don't strip your teeth), PEPPERMINT, CINNAMON, or FENNEL (flavor / freshening).

Keep in mind essential oils are highly concentrated. Always use tiny quantities and make sure it's a kind that won't harm with ingestion. Ex. Peppermint and spearmint are fine; wintergreen EO should never go in your mouth.

An ideal container is a baby food jar which is glass and therefore safe for you (no EOs in plastic). Get baby food jars free on Freecycle - parents always have too many.
alapiana says: Dec 6, 2011. 7:47 AM
So with those essential oils, you only mix 1-2 drops of one oil per cup of b.soda? You said the different oils target different areas, do you switch it up daily? Do you use more than one type of oil per mixture? Do you mix it ahead of time and jar it?
Idea Gal says: Jan 24, 2012. 12:09 PM
Sorry for the delay.
In a nutshell: 10-20dr / cup. No. Yes. Yes.

I can't remember how much I had in my old recipe, but I'm thinking it was between 10-20 drops of various essential oils per cup of baking soda. There were two recipes I used (I'm sorry, the site I got them from is defunct and I just add EOs randomly now). One recipe was the lemon oil one and you were supposed to use it once per week. The other was a daily recipe and had all the germ-killing EOs and then you chose either cinnamon or fennel for flavor and the other compounds. Fennel was supposed to be more soothing if you had painful mouth issues. Mints were supposed to be good too, but stick with either peppermint or spearmint - I'm not sure at what quantity wintergreen is toxic. I mix in advance and keep in a glass jar. I stir it with an old wooden chopstick, aiming to disperse the EOs around the soda as much as I can; then I shake the jar up. Keep the lid on when not using so the EOs stay in the jar.

There's no perfect mixture. Play with the amounts aiming for effectiveness (kill germs) at a flavor level you like.

FYI, mint is contra-indicated if you take homeopathic remedies. Otherwise, it's fine.
achiaroscurosoul says: Nov 30, 2011. 7:58 AM
So...how exactly do you make yours? You mix the oils and baking soda ahead of time? What kind of ratio do you use for non-lemon oil? Also, theoretically, if you mixed it with a bit of hot water or peroxide wouldn't it turn into a paste? Or would that make it not work as well?
Idea Gal says: Jan 24, 2012. 12:22 PM
Sorry for the delay.

As for paste, you can turn it pasty each time you brush, because you probably start with a wet toothbrush and a wet mouth. You can add more water in that moment if you feel like it. Soda still provides gentle abrasion and EOs still provide cleaning power.

Stay away from hot water. It's okay to use on the spot when brushing, but you wouldn't keep your tooth powder and essential oils in hot water. I'm not even sure what using water in the recipe would do, but if you really want to try it, use filtered cold water. If you can't afford a filter, leave your water unlidded for 12 hours first to let the fluoride evaporate.

My recipe lasts me months. I am unsure how soda + water + EOs would do over months' time. A separate peroxide + EOs (no soda) is great for mouthwash and it does last.

See my other comment for more info.
lbooterfelden says: Apr 12, 2011. 8:28 PM
Interesting, I had on idea that EOs aren't supposed to mix with plastic! What's the rationale? Very glad I read that if it's not safe, so thank you.

I like your take on 'supersweet' pastes. It's like cereal: If we start our kids on oatmeal and fresh food instead of Chocolate Frosted Sugar Bombs, they'll be more likely to make wise decisions. Toothpaste is one of those things that gets a lot less attention than food, but is equally as important because it's absolutely laden with harsh chemicals.
Idea Gal says: Apr 13, 2011. 1:59 PM
In terms of safety, it depends on your level of purism, because it seems there is something wrong with everything these days. Personally? I do whatever I can that is good for my body and the environment, but not in a way that will stress me out. Glass jars are easy enough to work with, and baby food jars are sturdy, so if your kids drop them several times, they'll probably stay intact.

So, acidic things (like tomatoes, honey, citrus) are not good in plastic containers because they leech the toxins from plastic. Any type of oil, however, is worse in plastic, and causes the plastic to break down faster, meaning whatever is in the plastic gets into whatever food or body product is contained there. I avoid plastic whenever practical.

When I travel, I do use plastic containers, because it's a short period of time and traveling with glass is a hassle. But at home, as much as I can, I use glass jars (whatever leftover ones I have from buying food at the store - i don't buy special jars). Stainless steel containers are equally safe, but you'd have to buy them rather than getting them naturally just through buying groceries, like you do with glass.
Pinky212 says: Feb 22, 2011. 4:17 AM
Sheez! Did I sound snippy, or what??!! I'll blame it on being in pain from arthritus -- which is true -- but no excuse for my bad attitude! SORRY!

When I get some time, I'll browse the DIY instructables more.

I HAD to use just the baking soda when I became ill from a chemical overload from a manufacturing company I worked at. Brushing with baking soda alone was part of the detoxification process and at that point, I'd do most anything to to get my memory back and stop bumping into the right side of the door frame when walking through a doorway! I guess I just didn't notice the taste it given how ill I was at the time.
mousewrites says: Feb 22, 2011. 8:24 AM
You did sound a bit snippy, but all is forgiven!

The detox regimen had you use straight baking soda? Man, now i'm even MORE concerned with what's in my toothpaste! What else did they have you do? I'm really sorry you had to go through that, but...

I also learned about MAOI's and catecholamines. They have to do with depression, but depression isn't just a mood thing. It can refer to the depressed state of an organ's functioning. In my case, my liver had depressed functioning. Some foods aid and some foods harm. The list is on my fridge yet. It's too long to include here.
Pinky212 says: Apr 15, 2011. 2:35 PM
mousewrites, I was referred to an allergist for testing of the usual allergans. It was there that we found out I was sensitive to glycerine. Try finding a soap that doesn't have glycerin in it! I was not sensitive to the pine, oak, peanuts, etc. but broke out in a wide red band on my stomach from the glycerine agent used to inject the pine, oak, peanuts, etc.

I could use NO chemicals for cleaning myself or hosuekeeping! I learned to use vinegar and baking soda for all cleaning. This was back in 1986 -- before the "greening of America". I was told to eat only fresh or canned food, no beef (due to the antibiotics, etc.), range fed chicken, fish (not in any brine), and no pork (same problems as the beef. As to the canned food, the rule of thmb was: If you can't pronounce it, don't eat it!

I could use no make-up, my husband put his aftershave on outside, I couldn't iron any permapress clothes (yep, those dress shirts my hubby wore that get wrinkled after several washings) because of the fomaleyde, couldn't wear any new clothing, and we had to air out (for 2 weeks) our newly purchased home that had its interior painted.

My diet for three days was only white long grain rice. I was warned that I'd get a headache like I'd never had before because my body would be detoxifying from the chemicals the same as a drug addict's does when the addict goes off street drugs. The doctor was kidding.

He said if I doubted his recommendations, then I should go home, drink some Jello, and see how I felt. Jello is chalk full of coloring!

The therapy was a vitamin and mineral regimen determined from blood tests. Mine were completely out of wack! I was taking mega doses of some, along with selenium, an anti-oxidant. Along with the vitamin and mineral regimen was the food diet, of course, and the other chemical avoidances.

It was a long process to add one food to my diet for three days, and then another, etc. NO artificial coloring, flavorings or preservatives. My memory finally came back but there was a time when I couldn't remember my own name, and referred to the refrigerator as "that big white box that keeps our food cold".

I still watch what I eat but now I'm just careful not to overload. I stay out of carpet stores, auto body shops, and anywhere else where fumes could concentrate, including rush hour traffic. If I have to drive in a metropolitan area, I go there during the wee hours of the morning (2 a.m. - 4 a.m.) Farmers spraying herbicides, etc. are something I watch for in the spring and fall, along with spraying for pest control in the apt. building where I now live. There are probably more things I did back then -- but I forget. LOL BTW, I call "cheating my diet" when I have about 6 M&M's (that colorful candy coating, you know.)
yayanator says: Feb 3, 2012. 6:14 AM
So, I made this, then put in tubes, and all the liquid separated out and came out of the toothpaste. Now I have tubes of baking soda.
mandismuses says: Jan 9, 2012. 7:13 PM
*sigh* Chalk up a disaster for the blonde. Tried this, and immedietly capped it into a container. An hour later my mom walked in and saw that it was swollen beyond belief on the steps (where I had put it out of sight/out of mind until I went upstairs) and poked it. Because, heck, why not I guess. It exploded EVERYWHERE. It made such a mess. So....I liked it, it tasted fine (what was left of it, anyways), but my question is- how do I get it to NOT explode so I can keep it?:)
irelands.the says: Jul 5, 2011. 12:02 AM
For those out there who would like to make this taste even better *AND* be even better for your teeth, I make mine with about 50% xylitol which is a naturally occuring sugar alcohol that tastes exactly like sugar, but is toxic to the *methanogenic* bacteria responsible for tooth decay (staphlococcus mutans) but leaves the beneficial bacteria alone. It's also great for reducing the bacteria that are responsible for ear infections, and bad breath! It's 100% non-toxic (except to dogs), and assists the salivary tooth re-mineralization process.

Also, as someone mentioned, glycerin prevents *anything* from adhering to your teeth, which on the surface (pardon the pun) seems like a good thing. The down side is that it acts as a barrier to the remineralization process. I am still looking for a good alternative to glycerin. I would love to make a replacement toothpaste that behaves the same convenient way.
alapiana says: Dec 6, 2011. 7:49 AM
You said you use Xylitol and do you combine that with 50% baking soda and that's it?
asayers says: Oct 24, 2011. 6:38 PM
Flouride is added into our water supply (here in Australia too) out of habit, its a chemical by-product sold to water companies. Flouride does interfere wth brain matter, it creates a coating on the pineal gland (from what I have read).
We get everything our bodies need from a natural diet, sleep and sunshine, simple. (Thinkabout it: lycopene as a supplement is from red foods, for the heart. If you eat tomatoes and peppers (capsicums) you get exactly the same stuff, no bottles or additives. Google 'doctrine of signatures', everything in nature has medicine for us.. This idea makes little money for the 'company'...
On a toothpaste note, I use bicarb and peppermint oit (soon to be spearmint, a bit milder). bicarb at first was a bit ick, but now Im very used to it. Its cheaper, safer, and theres NO plastic stupid little plastic tubes going into landfill from it.
etira says: Oct 22, 2011. 2:37 PM
According to this site:
http://www.care2.com/greenliving/toothpaste-turmoil.html

Avoid hydrogen peroxide and glycerin, which are drying and can lead to tooth sensitivity.

Just more information for your powerful decisions about what to use or not.
nelsonk says: Jul 26, 2011. 4:06 PM
i am slightly confused so this tooth paste isnt bad for me right????
SparkyGage says: Aug 21, 2011. 8:41 PM
If you swallow it, it could make you sick. Just like store bought tooth paste. It's not likely to kill you unless you eat a plate full, but if you swallow it instead of spitting it out, you could get a stomach ache - again, just like store bought tooth paste. There is nothing in this that isn't in several name brand tooth pastes. You can actually use the baking soda and peroxide to "boost" you favorite toothpaste.

One other ingredient that can be added is a dash of salt - it's good for the gums and preventing canker sores.
psm1964 says: Jun 15, 2011. 10:03 AM
Is there an ingredient you can add to the toothpaste for sensitive teeth?
lassensurf says: Jul 1, 2010. 4:48 PM
Now if you could get some fluoride or at the least calcium into the mix to help put the minerals back into your teeth like most other toothpastes do, you'd really have something. Maybe get some liquid fluoride supplement (not sure if it's widely available anymore, be careful with it) and add a few drops of it to the toothpaste batch (again, don't eat it). Calcium carbonate is like limestone and doesn't dissolve except in acidic solution that'll dissolve your teeth as well, so don't try that. Also, licorice has been shown very well to kill a lot of oral bacteria (including the ones that help form cavities), so if you like the taste of licorice that'd be a top recommendation.
lbooterfelden says: Apr 12, 2011. 8:31 PM
If you get enough fluoride in your meals, your teeth will get a share of the nutrients. Too much is damaging to brain matter!
mizar5 says: Dec 26, 2010. 7:39 AM
You can put some ionic trace minerals in with the mix in order to get the calcium and phosphorus needed for re-mineralization of the enamel. I wouldn't be too concerned about the fluoride, as the process of re-mineralization doesn't require it. It is more of an adjunct to the process. Besides there is probably enough natural fluoride in our foods without having to supplement. I would be more concerned about the frequent use of the peroxide for the gum tissue damage it can cause. Besides, it is a lousy anti-microbial since it dilutes too quickly with the saliva.
aerayne says: Jul 26, 2010. 7:22 AM
Fluoride is highly toxic and has never been safe for human use even in small amounts. The science foundation says the ONLY safe amount is zero. Please take it from someone who lives with toxic fluoride poisoning. It is an incurable illness that causes extreme pain, fatigue and a number of other issues. Sound familiar? It should. Google "toxic fluoride poisoning" and research it before it's too late. I wish I had. On a positive note, I make very simple paste using baking soda, water and mint. I am going to be trying peppermint oil next time. For now, I'm using fresh peppermint. And really, since when did toothpaste taste good after you were too old for the kids stuff?

lassensurf says: Jul 3, 2010. 12:33 PM
Wow. Some pent up steam looking for an outlet here. Lemme give a history of dentistry and fluoride: guy a while back does some comparison studies of communities and tooth decay and realizes communities with fluoride in the water (just found in the water on it's own.) FLUORIDE, not FLUORINE!! VERY DIFFERENT!!!!!!!!! Fluorine is the reactive toxic gas similar to chlorine. Fluoride is the relatively inactive ion similar to chloride. Back to the story: communities eager to fix everybody's teeth dump a bunch of fluoride into their water supplies only to realize, too much causes problems (stained but decay-free teeth, brittle bones, kidney problems etc). Next question, how much prevents tooth decay and how much is bad for you? After decades of study, it's recommended that between .5 ppm and 1.5 ppm is very adequate to create a protective layer on the teeth that's more resistant to acid erosion, thus more resistant to the acid-producing bacteria that cause tooth-decay (calcium minerals dissolve in acid. ex. limestone, hard water deposits, bones etc) without creating any measurable, notable, or observable differences in the people who used it. Most communities use .7 to 1ppm. That is also WELL within the kidney's very capable realm of filtration to dispose of in urine just like it disposes of every other excess or extra mineral or ion your body doesn't want. Methoxy fluorine and all those other things mentioned don't form from fluoride, it's too stable but fluoride can be pulled from the reactive methoxy-stuff. They're formed from fluorine which is so reactive it's not found in nature (much like sodium metal, or even calcium metal, only the ionic, non-reactive forms are found or stable in any sort of solution of pretty much anything). Fluoride likes calcium (not really much else) and there's lots of it in your teeth so it sticks and contributes to the crystal of your enamel. I can find you the 3D diagram of "calcium-fluoro-apatite" crystal if you like. If a dentist recommends all the fluoride you can take, than you either misunderstand him, or he's really old and doesn't keep up with dentistry's developements, or perhaps he was taught differently in his country's dental schools. I originally mentioned that it might be hard to find the liquid supplements because it was thought for a time that fluoride's effect on teeth was through your body's physiological systems (picked up in the blood and handled from the inside and worked into the teeth from there). That's been found to be untrue (who found this out? Dentists). So that has been largely discontinued but there are a few old-school dentists out there who recommend it. So modern dentists recommend the very very small amounts in water and topical applications only: toothpaste, varnishes, rinses, etc, Stuff you DON'T EAT. The governing body that grants dentist's their license is from the local state, NOT the ADA. If dentists are destroying people's teeth and getting away with it then they will lose their license. The ADA's best interest is to keep a high quality of care among it's members so that dentists aren't super-regulated like is happening to the medical field. The licensing board's purpose is to protect the public from bad dentists and the mistrust and harm that would ensue if allowed to continue. Those who distrust dentists usually are people who have had bad experiences or are generally mistrustful of anything they can't control or don't understand, or they have been fed bad information by well-intentioned-but-misinformed persons. I worked in a health food store for 15 years, I've seen it.

Well put.
In addition, there is evidence that fluoridated drinking water, in the range of 1.0-1.06 ppm, helps to protect against bone fracture later in life (after 50). If the levels were either too low (<.34ppm) or too high (>4.32ppm) the risk increased [1]. Another study suggests that the systemic administration of fluoride may no longer be prudent in developed countries because topical treatments such as toothpaste and dentist administered topical fluoride can meet children's needs [2].

So, some fluoride is beneficial to your teeth and bones, but too much is bad. Such a simple, reasonable outcome.

Not sure what you're trying to add to the discussion. As noted above, flouride is beneficial unless the levels are VERY high. If you have something to add, please cite peer-reviewed articles from well-known and respected journals. Web sites (especially those with an agenda) are not considered a reliable source when supporting a scientific argument.
