Introduction: Homemade Toothpaste


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 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.

Step 2: Mix It Up


Gather some measuring tools from your kitchen - all of these products are food safe, so clean them as normal when done.

Blend your ingredients, and adjust to taste.  Sample it by rubbing a bit on your teeth with your finger, rather than tasting it outright.  That will give you a better idea of what it's going to be like when you use it.

Combine ingredients until you get the flavor and viscosity that you prefer.

Step 3: Storage


Hydrogen peroxide is UV sensitive, so be sure to store your toothpaste out of sunlight, or in an opaque container.

I thought using a pastry bag would be cute and convenient (since I have them on hand).  The only drawback to this is that there's no way to cap it!  So I made the toothpaste extra paste-y, and problem solved.  Using a tube squeezer from a paint shop helps keep the end closed and gets out every last drop.

You can also find plastic tubes to fill at outdoor and camping stores, like REI (which I might do next time, if I can think of a cute label to put on it).

Other options include storing your toothpaste in a squeeze bottle or jar. 

Of course, if all of this sounds like too much effort, you can always just dip your toothbrush in hydrogen peroxide, and then in baking soda.  Job done.

Instead of Stevia, try using Xylitol. It's also good for your teeth! https://en.m.wikipedia.org/wiki/Xylitol

I'm going to DIY this myself and post it. I'm working in several projects.

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.

Agreed. People need to pay attention, not bicker over trivialities and superficial differences. The finger-pointing of the fragmented Left wing is a real problem, allowing the other problems to continue without exception. It's frustrating to watch...

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.

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!

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?

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.

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?

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.
