Homemade tooth-whitening tools
Many different tooth-whitening techniques are promoted online, such as making toothpaste by mixing baking soda and hydrogen peroxide, brushing your teeth with apple cider vinegar or rubbing your teeth with orange peels or other fruits. However, researchers haven’t done the necessary studies to show that these techniques are effective or safe, Dr. Kugel says.
Arm & Hammer baking soda toothpastes can remove surface stains, but these toothpastes contain additional ingredients not typically found in your cupboard. Adding hydrogen peroxide to baking soda likely won’t make much a difference, given that the compound isn’t in contact with your teeth for very long. Additionally, the citrus acid of orange peels may be able to make your teeth chalky white, but “they will probably also do a lot of damage to the enamel,” Dr. Kugel says. “In my opinion, any homemade product can be harmful, because it can be easily misused or overused,” Dr. Plotino says, adding that consumers should also be wary of tooth-bleaching businesses operated in nondental settings.Back to top
