Fluoride is a naturally-occurring mineral that helps rebuild tooth enamel and reverse early signs of tooth decay. Your body takes in fluoride in two ways: systemically and topically. Systemic fluorides are swallowed, including fluoridated water (most tap water) and dietary fluoride supplements. Topical fluoride is applied directly to the teeth via toothpaste, mouth rinses and treatments at the dentist's office.
According to the Indian Dental Association, fluoride enhances the tooth remineralisation process. Fluoride found in a person's saliva will absorb onto the surface of a tooth where demineralisation (tooth decay formation) has occurred.
Fluoride treatments applied by a dentist are especially good for people with a higher risk for tooth decay or erosion. If you have dry mouth, weak enamel, poor oral health or if you have crowns, ask your dentist if applying a fluoride varnish would help protect your teeth.
According to Stanford Children's Health, children can begin getting fluoride treatments at the dentist once their first tooth appears. However, be aware that children under two years old should still use a fluoride-free toothpaste. If too much fluoride is ingested as a young child, before the adult teeth have erupted, it can lead to dental fluorosis.
Don't worry; the fluoride varnish applied by the dentist is safe to help prevent tooth decay in children. They only use a small amount of fluoride, and hardly any fluoride gets swallowed.
Professional fluoride treatments usually only take a few minutes. The fluoride might come in the form of a gel, foam or varnish. It can be applied with a swab or brush or placed in a tray held in the mouth for a few minutes.
After the treatment is applied, don't eat or drink for at least 30 minutes to allow your teeth to absorb the fluoride and help repair microscopic areas of decay.
Depending on your oral health, your dentist might recommend fluoride treatments every 6–12 months. If you're at a higher risk of developing tooth decay, your dentist might also recommend other preventive measures, such as over-the-counter or prescription fluoride mouth rinses or gels, or an antibacterial mouth rinse.
Ask your dentist about the benefits of fluoride treatments, and keep up your daily dental hygiene regimen. They're both excellent ways to help maintain your strong, healthy smile.
