WE’VE ALL HEARD of the active ingredient in toothpaste: fluoride. It supplies tooth enamel with important minerals to keep it strong and it protects against tooth decay. It’s the one ingredient toothpaste must contain to earn the American Dental Association’s Seal of Acceptance. But what else is in toothpaste?
1. Mild abrasive ingredients help scrub the surfaces of our teeth clean as we brush (and it doesn’t take more than a soft-bristled toothbrush and gentle brushing to get the job done).
2. Foaming detergents help the toothpaste reach every tooth. (Fun fact: the foam is why actors rarely use toothpaste when they brush their teeth onscreen. It’s too messy for TV!)
1. Humectants keep toothpaste from drying out, so that it can come out of the tube in a smooth piece.
2. Flavoring and sweeteners make toothpaste taste good, but they can’t include actual sugar and still get the ADA Seal of Acceptance. Toothpaste for adults is usually a strong, minty flavor, but that can be overpowering for kids, which is why theirs often tastes like fruit or candy.
For people experiencing tooth sensitivity, numbing and cooling ingredients might be ones to look for. These specially formulated toothpastes can help with jarring temperature changes and other sensitivity triggers, but they can’t fix a toothache and they’re no replacement for treatment from the endodontist.
