Myth: Chocolate causes cavities.
Fact: Candy alone is not responsible for cavities. Cavities are formed when bacteria in the mouth metabolize sugars and starches from any type of food (soda, candy, juice, bread, rice and pasta) to produce acid. This acid then eats through the enamel of the tooth, causing a cavity.
The protein, calcium and phosphate content of milk chocolate may actually protect tooth enamel, and its naturally-occurring fat content means that chocolate clears the mouth faster than other candy, reducing the amount of time its sugars remain in contact with tooth surfaces.
Regular fluoride use, proper oral hygiene to remove fermentable carbohydrate residue and the application of plastic sealants can all help prevent the formation of cavities—whether you avoid chocolate or not.
