Fluoride is effective in preventing cavities and tooth decay and in preventing plaque from building up and hardening on the tooth’s surface. A fluoride treatment in your dentist’s office takes just a few minutes. After the treatment, patients may be asked not to rinse, eat, or drink for at least 30 minutes in order to allow the teeth to absorb the fluoride. Depending on your oral health or your doctor’s recommendation, you may be required to have a fluoride treatment every three, six, or 12 months.

Fluoride is a naturally occurring element that has been shown to help strengthen teeth in children and also prevent decay in people of all ages. Topical fluoride, in particular is helpful for promoting oral health. The American Dental Association has publicly endorsed the use of fluoride for the prevention of dental caries, as has the American Academy of Pediatrics and the American Medical Association.

You may need fluoride treatments if your drinking water is not fluoridated or if you are experiencing certain symptoms, such as receding gums. Fluoride treatments can also provide oral support and prevent decay if you wear orthodontic braces or are taking medications that cause dry mouth.

What to Expect

Fluoride treatments are painless and can be administered in your dentist’s office at your twice-yearly check-ups and cleanings. Your dentist will distribute fluoridated gel, foam or varnish into a tray and place it over your teeth. The treatment takes only a few minutes and is only required between one and four times per year.

The ADA recommends supplementing your fluoridated drinking water or fluoride treatments with a fluoridated toothpaste.
