Cavities are the result of teeth-destroying acids made by bacteria, Nelson-Dooley explains. They’re small holes in the surface of the tooth, but if they reach the tooth’s pulp, they may require a root canal.
The cause lies once again in an imbalanced oral microbiome. One bug in particular — Streptococcus mutans — has been implicated in cavities. This bacteria is present in cavity-free mouths as well, but there, friendly bacteria keep S. mutans at bay.
“If you aren’t keeping up with your oral hygiene, if you’re eating sugar, and if your saliva isn’t flowing well, it increases acid in your mouth, which sets off a chain of events that disrupts the bacteria that live on your teeth and causes cavities,” notes Nelson-Dooley. “Dietary changes like cutting out sugar, reducing packaged foods, and eating more veggies are among the most powerful ways to control your oral microbiome and prevent cavities.”
If you’re prone to cavities, diet is an important place to start.
