Every day, our tooth enamel loses minerals when our teeth are exposed to acids such as sugar and plaque. Loss of these minerals causes our teeth to weaken and become prone to decay. One way we can help strengthen and re-mineralize our enamel is through the use of fluoride. Fluoride is a mineral that naturally occurs in many foods and water and makes the tooth more resistant to acid attacks. In children under 6 years of age, fluoride becomes incorporated into the development of teeth, making it difficult for acids to weaken the teeth. Adults also benefit from fluoride. New research indicates that topical fluoride (from toothpastes, mouth rinses, and fluoride treatments) are important in fighting tooth decay in adults. In addition, people with certain conditions such as:
• Dry mouth
• Gum recession
• History of frequent cavities
• Presence of crowns, bridges or brace
Are at a higher risk for tooth decay and should incorporate a regular fluoride treatment into their home care routine.
