Avoid frequent snacking and sipping.
Whenever you eat or drink something other than water, you help your mouth bacteria create acids that can destroy your tooth enamel. If you snack or drink throughout the day, your teeth are under constant attack.
Eat tooth-healthy foods
Some foods and beverages are better for your teeth than others. Avoid foods that get stuck in grooves and pits of your teeth for long periods, such as chips, candy or cookies. Instead, eat food that protects your teeth, such as cheese, which some research shows may help prevent cavities, as well as fresh fruits and vegetables, which increase saliva flow, and unsweetened coffee, tea and sugar-free gum, which help wash away food particles.
Consider fluoride treatments
Your dentist may recommend a fluoride treatment, especially if you aren't getting enough fluoride through fluoridated drinking water and other sources. In a fluoride treatment, your dentist applies concentrated fluoride to your teeth for several minutes. You can also use fluoridated toothpaste or mouthwash.
Ask about antibacterial treatments
If you're especially vulnerable to tooth decay — for example, because of a medical condition — your dentist may recommend special antibacterial mouth rinses or other treatments to help cut down on harmful bacteria in your mouth.
