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. 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 the teeth once they have erupted by seeping into the outer surface of the tooth enamel, making the teeth 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 both children and adults 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. (Note: the Town of Yarmouth does not have a fluoridated water supply). 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.
Although most people receive fluoride from food and water, sometimes it is not enough to help prevent decay. 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.
Fair to poor oral hygiene habits.
Frequent sugar and carbohydrate intake.
Inadequate exposure to fluorides.
Inadequate saliva flow due to medical conditions, medical treatments or medications.
Recent history of dental decay.
There are many benefits in the use of fluoride, for people of all ages. When children are young and their teeth are forming, fluoride joins with the enamel surface and makes it harder and more decay-resistant.
The benefits for adults are just as great. Fluoride can help repair an early cavity, even before it's become visible in the mouth, by rebuilding the enamel layer of the teeth. Fluoride is also helpful in older adults to help solve the problem of root caries or root sensitivity. And fluoride rinses or gels are sometimes prescribed to help eliminate germs that cause gum disease.
Another highly effective time for fluoride application is immediately following your cleaning in the dental office. A topical gel or foam is applied with the use of a tray or with a cotton applicator. Fluoride is an important part of every tooth decay prevention program.
When combined with the good hygiene habits of brushing and flossing, the number of cavities in children and adults can be dramatically reduced. 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.
