After your general checkup and clean with your dentist, he or she may recommend fluoride application. This is especially useful in patients with a higher risk of developing caries (tooth decay).
Fluoride is a mineral that helps to prevent tooth decay and can repair teeth if the tooth decay is in the early stages of the disease.
Fluoride is available in toothpastes but the fluoride gel used in the dental office is of a much stronger concentration than that in toothpastes or fluoride mouthrinses that may be available in a store or at a pharmacy.
Professional fluoride treatments typically take only a few minutes. The fluoride gel is placed in a soft tray that is held in the mouth for several minutes.
