Dentists Reveal the Worst Foods for Your Teeth

According to a 2016 study published in Advances in Nutrition, cavities affect an estimated 80% of the world’s population—and almost a quarter of adults in the United States having untreated cavities. A leading cause is poor diet quality and high sugar consumption, the study says. But cavities are just one of many oral health issues that can be caused or exacerbated by the foods you eat, says Joseph Dill, D.D.S., M.B.A., chief dental officer at Delta Dental Plans Association.

“Daily diet plays a direct role in oral health, which is essential to overall health,” Dr. Dill explains. “Brushing your teeth, flossing, and visiting the dentist regularly are all typically associated with maintaining a healthy smile—but there’s more to oral health. The important nutrients from a healthy diet strengthen the bone that supports your teeth and protects against tooth decay, gum disease, and oral cancer.”

On the flip side, a diet that lacks nutritional value can have the opposite effects, causing staining, enamel erosion, and tooth decay. “That’s why it’s so important to brush at least twice a day with a fluoride toothpaste and floss once a day,” Dr. Dill adds.

To ensure you’re staying away from the top offenders and eating as many teeth-friendly foods as possible, below is a list of the worst foods for your teeth, according to dentists. It includes all those foods your mom limited growing up—like candy and soda (sorry!)—and a few others that might surprise you.
