Preventing Tooth Decay: Everyday Habits That Matter

How Cavities Form

Tooth decay begins when bacteria in plaque feed on sugars and starches and produce acids. These acids draw minerals out of enamel, gradually weakening it. Early on, saliva and fluoride can help repair this damage, but if the acid attacks continue, a cavity can form and progress deeper into the tooth.

Daily Home Care

Brush twice a day for about two minutes with a soft-bristled brush and fluoride toothpaste, paying attention to the gumline and back teeth. Clean between your teeth once a day with floss or interdental cleaners, since a toothbrush cannot reach those surfaces well.

After brushing at night, spitting out excess toothpaste rather than rinsing right away can let fluoride stay on the teeth a little longer.

Diet and Snacking

How often you eat sugary or starchy foods matters as much as how much. Frequent snacking and sipping sweetened drinks keep teeth under repeated acid exposure. Enjoying treats with meals, choosing water between meals, and limiting sticky snacks can make a meaningful difference. Sugar-free gum after eating may help stimulate protective saliva.

Professional Support

Regular checkups allow early decay to be found when it is small and simple to treat, or even reversible. Professional fluoride treatments and dental sealants offer additional protection for people who are more prone to cavities, including children and adults with dry mouth.
