1) Brush your teeth at least twice a day and after every meal, using fluoride-containing toothpaste. To clean between your teeth use floss. If you can’t brush after eating, at least rinse your mouth with water.
2) If you have a high risk of developing cavities use a mouth rinse with fluoride.
3) Visit your dentist. Get professional teeth cleanings and regular oral (mouth) exams.
4) Consider dental sealants. A sealant is a protective plastic coating that’s applied to the chewing surface of back teeth, sealing off the areas that tend to collect food. The sealant protects tooth enamel from plaque and acid.
5) Avoid frequent snacking and sipping. Whenever you eat or drink beverages other than water, bacteria can create acids that can destroy your tooth enamel. If you snack or drink throughout the day, your teeth are under constant attack.
6) Some foods such as fresh fruits and vegetables increase saliva flow. Also, unsweetened coffee, tea and sugar-free gum help wash away food particles.
7) Consider fluoride treatments.
8) If you’re especially vulnerable to tooth decay — for example, because of a medical condition — your dentist may recommend special antibacterial mouth rinses.
