Fluoride is the most effective agent available to help prevent tooth decay. It is a mineral naturally present in varying amounts in almost all foods and water supplies. The benefits of fluoride have been well known for over 50 years and are supported by many health and professional organizations.

Fluoride works in two ways:
- Topical fluoride: Strengthens teeth after they have erupted by seeping into the outer surface of the enamel, making them more resistant to decay. Topical fluoride is obtained from fluoride-containing dental products such as toothpaste, mouth rinses, and gels. Dentists and dental hygienists generally recommend a professional fluoride application twice a year for children during dental check-ups.
- Systemic fluoride: Strengthens both erupted teeth and developing teeth under the gums. Systemic fluoride is obtained from most foods and community water supplies. It is also available as a supplement in drops or tablets prescribed by a dentist or physician. Drops are generally recommended for infants, and tablets for children through the teen years. Monitoring fluoride intake is important, as excessive consumption during tooth development can cause fluorosis (white spots on the teeth).
When Fluoride Treatments May Be Recommended
Although most people receive fluoride from food and water, it may not always be sufficient to prevent decay. Your dentist or dental hygienist may recommend home or professional fluoride treatments for the following reasons:
- Deep pits and fissures on the chewing surfaces of teeth
- Exposed and sensitive root surfaces
- Fair to poor oral hygiene habits
- Frequent sugar and carbohydrate intake
- Inadequate exposure to fluorides
- Reduced saliva flow due to medical conditions, treatments, or medications
- Recent history of dental decay
Remember: Fluoride alone will not prevent tooth decay! It is important to brush at least twice a day, floss regularly, eat balanced meals, reduce sugary snacks, and visit your dentist regularly.
