Fluoride is the most effective agent available to help prevent tooth decay. It is a mineral that is naturally present in varying amounts in almost all foods and water supplies (including natural spring water). The benefits of fluoride have been well known for over 50 years and are supported by nearly all health and professional organizations.
Fluoride works in two ways:
Topical fluoride strengthens the teeth once they have erupted by reacting with the outer surface of the tooth enamel, making the tooth enamel harder and more resistant to decay. We gain topical fluoride by using fluoride containing dental products such as toothpaste, mouth rinses, and gels. Dentists and dental hygienists generally recommend that children have a professional application of fluoride twice a year during dental check-ups.
Systemic fluoride strengthens the teeth that have erupted as well as those that are developing under the gums. We gain systemic fluoride from most foods and our community water supplies. It is also available as a supplement in drop or gel form and can be prescribed by your dentist or physician. Generally, fluoride drops are recommended for infants, and tablets are best suited for children up through the teen years. It is very important to monitor the amounts of fluoride a child ingests. If too much fluoride is consumed while the teeth are developing, a condition called fluorosis (white spots on the teeth) may result.
In almost all cases, it is relatively easy to get the recommended amounts of fluoride either topically or systemically. However, if you live in an area with very low fluoride levels in the drinking water supplements may be prescribed. Your dentist or dental hygienist may recommend the use of home and/or professional fluoride treatments for the following reasons:
Deep pits and fissures on the chewing surfaces of teeth.
Exposed and sensitive root surfaces as they are especially decay prone.
Fair to poor oral hygiene habits.
Frequent sugar and carbohydrate intake.
Inadequate exposure to fluorides.
Inadequate saliva flow due to medical conditions, medical treatments (radiation treatment) 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 on a regular basis.
