A cavity can begin with something as simple as repeated exposure to sugary or acidic foods. At first, the damage may be so small that you do not notice anything. Over time, however, acids produced by bacteria in dental plaque can weaken the tooth enamel and eventually create a permanent hole.
The good news is that very early tooth enamel damage may sometimes be stopped or remineralized when it has not yet developed into an actual cavity. Good daily oral hygiene, fluoride toothpaste, healthy eating habits, and regular dental care can help protect your teeth and reduce the risk of further damage.
One of the most important habits is brushing your teeth twice a day with fluoride toothpaste. Brush gently for about two minutes, making sure you clean the outer, inner, and chewing surfaces of your teeth. Fluoride helps strengthen enamel and makes it more resistant to acid attacks.
Do not brush aggressively. Using excessive pressure can irritate the gums and contribute to enamel wear. A soft-bristled toothbrush and gentle circular movements are generally preferable.
Cleaning between your teeth is just as important. Food particles and plaque can remain in spaces that a toothbrush cannot reach. Dental floss or an appropriate interdental cleaner can help remove this buildup and reduce the risk of cavities between the teeth.
Your diet also plays an important role in dental health. Frequently eating sugary foods and drinking sweetened beverages gives oral bacteria more opportunities to produce acids that attack enamel. Try to limit frequent snacking on candy, cookies, pastries, sweetened drinks, and other foods high in added sugar.
