What Causes Cavities? Why Some People Get More Cavities Than Others

What causes cavities? Why do some people get cavities even when they brush and floss every day, while others rarely experience tooth decay? Cavities are one of the most common dental problems, but the reasons behind tooth decay are more complicated than simply eating too much sugar or not brushing your teeth.

In this video, Dr. Hana Yoon, explains what causes cavities, how tooth decay develops, why some people are more prone to cavities than others, and what you can do to prevent cavities and keep your teeth healthy.

• What are the best ways to prevent cavities?

How Do Cavities Form?

Your mouth contains a complex ecosystem of bacteria, some of which contribute to tooth decay. When you eat foods containing sugars or other fermentable carbohydrates, certain bacteria produce acids that weaken your tooth enamel through a process called demineralization.

Fortunately, your saliva and fluoride help repair early enamel damage through remineralization. However, when acid attacks happen too frequently or your teeth aren't able to remineralize effectively, cavities can develop.

Why Do I Keep Getting Cavities Even Though I Brush My Teeth?

Some people naturally have a higher risk of developing cavities due to differences in their oral microbiome, tooth enamel, saliva production, dietary habits, and other individual factors.

That means getting cavities doesn't necessarily mean you have poor oral hygiene!

How to Prevent Cavities and Tooth Decay

While you can't control every factor that contributes to cavities, you can reduce your risk by:

✔️ Brushing twice a day with fluoride toothpaste
✔️ Flossing daily to remove plaque between your teeth
✔️ Limiting frequent sugary snacks and drinks
✔️ Drinking water and supporting healthy saliva production
✔️ Scheduling regular dental cleanings and checkups
✔️ Treating early signs of tooth decay before they progress
