Stannous fluoride was introduced as an alternative to sodium fluoride for the prevention of cavities (tooth decay). It was introduced for this purpose by Joseph Muhler and William Nebergall. In recognition for their innovation, these two individuals were inducted into the Inventor's Hall of Fame.[1]
The fluoride in stannous fluoride helps to convert the calcium mineral apatite in teeth into fluorapatite, which makes tooth enamel more resistant to bacteria-generated acid attacks.[3] The calcium present in plaque and saliva reacts with fluoride to form calcium fluoride on the tooth surface; over time, this calcium fluoride dissolves to allow calcium and fluoride ions to interact with the tooth and form fluoride-containing apatite within the tooth structure.[4] This chemical reaction inhibits demineralisation and can promote remineralisation of tooth decay. The resulting fluoride-containing apatite is more insoluble, and more resistant to acid and tooth decay.[4]
In addition to fluoride, the stannous ion has benefits for oral health when incorporated in a toothpaste. At similar fluoride concentrations, toothpastes containing stannous fluoride have been shown to be more effective than toothpastes containing sodium fluoride for reducing the incidence of dental caries and dental erosion,[5][6][7][8][9] as well as reducing gingivitis.[10][11][12][13][14] Some stannous fluoride-containing toothpastes also contain ingredients that allow for better stain removal.[15][16] Stabilised stannous fluoride formulations allow for greater bioavailability of the stannous and fluoride ion, increasing their oral health benefits.[17][18] A systematic review revealed stabilised stannous fluoride-containing toothpastes had a positive effect on the reduction of plaque, gingivitis and staining, with a significant reduction in calculus and halitosis (bad breath) compared to other toothpastes.[16] A specific formulation of stabilised stannous fluoride toothpastes has shown superior protection against dental erosion and dentine hypersensitivity compared to other fluoride-containing and fluoride-free toothpastes.[19]
Stannous fluoride was once used under the trade name Fluoristan in the original formulation of the toothpaste brand Crest, though it was later replaced with sodium monofluorophosphate under the trade name Fluoristat. Stabilised stannous fluoride is now the active ingredient in Crest/Oral B Pro-Health brand toothpaste. Although concerns have been previously raised that stannous fluoride may cause tooth staining, this can be avoided by proper brushing and by using a stabilised stannous fluoride toothpaste.[15][16] Any stannous fluoride staining that occurs due to improper brushing is not permanent, and Crest/Oral B Pro-Health states that its particular formulation is resistant to staining.
