Fluoride

Topical fluorides are applied directly to the tooth enamel. Some examples include fluoride toothpastes and mouth rinses, as well as fluoride treatments in the dental office. Systemic fluorides are those that are swallowed. Examples include fluoridated water and dietary fluoride supplements. The maximum reduction in dental caries is achieved when fluoride is available both topically and systemically. Dentists have used in-office fluoride treatments for decades to help protect the oral health of children and adults, especially patients who may be at a higher risk of developing caries.

Professional fluoride treatments generally take just a few minutes. The fluoride may be in the form of a solution, gel, foam or varnish. Typically, it is applied with a cotton swab or brush, or it is used as a rinse or placed in a tray that is held in the mouth for several minutes. After the treatment, you may be asked not to rinse, eat or drink for at least 30 minutes to allow the teeth to absorb the fluoride and help repair microscopic carious areas. Depending on your oral health status, fluoride treatments may be recommended every three, six or 12 months.
