Second Opinion: I brush my teeth every day. How did I get a cavity?

Cavities are the softening of your enamel caused by acids, which form when bacteria break down sugar in your mouth.

Sugary and starchy foods cause more cavities because they feed the bacteria as they stick to teeth. Frequent snacking and sipping creates a continual acid bath over your teeth. With more exposures of acid, your enamel has no chance to recover before another attack.

Brushing twice daily with fluoride toothpaste is recommended for cleaning the teeth’s surfaces. The fluoride in toothpaste builds the enamel’s defenses against acid. Flossing once daily removes the plaque and bacteria from between the teeth and gums where the toothbrush cannot reach.

 Visit the dentist twice per year. We can catch cavities early and can help clean areas that are frequently missed. We also provide in-office fluoride treatment for prevention of future cavities.
