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 obtain topical fluoride by using fluoride containing dental products such as toothpaste, mouth rinses, and gels. Dr. Greco and his 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. 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. Dr. Greco or his dental hygienists 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.
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 Dr. Greco on a regular basis.
