Why do Dentists Use Prescription Toothpastes?
How does Fluoride toothpaste protect teeth?
All toothpastes help remove plaque (a film of bacteria that forms on teeth and gums every day). Plaque causes tooth decay and gum disease. Plaque left on the surface of your teeth produces acid that causes the breakdown of enamel (demineralize). This creates a weak spot in the tooth (cavity). It is the fluoride in the toothpaste that helps rebuild (remineralize) weakened tooth enamel. New enamel crystals form that are harder and more resistant to acid.
Who will benefit from a high fluoride prescription toothpaste?
Patients that have . . .
- a history of multiple cavities
- exposed root surfaces
- a dry mouth
- a large number of existing fillings and/or crowns
- poor oral hygiene
Prescription fluoride toothpaste contains a higher concentration of fluoride (5,000 parts per million) than over-the-counter (OTC) toothpaste (1,000 parts per million). OTC toothpaste reduces cavities by approximately 23%. A 5,000 ppm prescription toothpaste reduces the cavity risk even more, estimated to be a 42% reduction.
