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 dental products containing fluoride- such as toothpaste, mouth rinses and gels.

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. 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
• Dry mouth 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 twice a day and floss daily, have a balanced diet and  reduce sugary snacks, and have regular dental visits.
