Hi everyone! I got this great tip from my dentist and decided to try it out. This is my first Instructable and I hope it's not too boring for you to read. Even though the method only costs less than $1, it works! The secret is... peroxide! ( or H2O2)
Step 1: Step 1
Buy the peroxide. (duh) It should cost under $1.
Step 2: Step 2
You will only need about 3 tablespoons but I just eye-ball it and dump the extra. You can either dip your toothbrush in the peroxide and brush or you can swish it around in your mouth. The taste is not delightful but it will make your teeth whiter. WARNING: DO NOT SWALLOW!!!
