According to Popular Science, sugar itself is not what damages teeth. The mouth contains bacteria that feed on carbohydrates such as sugar and starch.
When the bacteria break down food, acid is produced. It is this acid that can slowly damage tooth enamel and eventually lead to cavities.
Professor and dentist Diana Nguyen from the University of California explains that the body is normally able to protect teeth on its own.
Saliva helps remove the acid and restore a more neutral environment in the mouth.

Bad habits increase the risk
Problems mainly arise when people snack frequently or drink sugary and acidic beverages throughout the day.
In those cases, the mouth does not have enough time to return to balance.
According to Popular Science, people were also able to develop cavities long before sugar became common. Other types of carbohydrates could create the same issue.
Regular brushing and flossing may therefore be just as important as limiting sugar intake.

Wait before brushing your teeth
Experts also recommend avoiding brushing your teeth immediately after drinking coffee, soda, or eating snacks.
When the mouth is acidic, tooth enamel becomes softer. Brushing right away can cause additional damage to the enamel.
Sugar is not the direct cause of cavities, but the acid produced when bacteria break down carbohydrates can damage teeth over time.
