Stannous fluoride is an alternative to sodium fluoride for the prevention of cavities (tooth decay). It was first released commercially in 1956, in Crest toothpaste. It was discovered and developed by Joseph Muhler and William Nebergall. In recognition of their innovation, they were inducted into the Inventor's Hall of Fame. [1]
The patient can then use this to hold a fluoride treatment against their teeth overnight or several minutes during the day. The concentration of fluoride in these gels is much lower than in professional products. [53] The self-applied sodium fluoride gel/foam typically contains 0.5% fluoride and stannous fluoride gel/foam contains 0.15%. [53]
What are the reasons that a toothpaste manufacturer would choose one over the other, and are there any reasons why a consumer might want to choose a sodium monofluorophosphate toothpaste in favor of a sodium fluoride toothpaste, or vice versa? –64.185.132.215 18:51, 7 February 2012 (UTC)
Fluoride is present in small amounts in plants, animals, and some natural water sources. The additional fluoride in toothpaste has beneficial effects on the formation of dental enamel and bones. Sodium fluoride (NaF) is the most common source of fluoride, but stannous fluoride (SnF 2), and sodium monofluorophosphate (Na 2 PO 3 F) are also used ...
A person living in an area with fluoridated water may experience rises of fluoride concentration in saliva to about 0.04 mg/L several times during a day. [14] Technically, this fluoride does not prevent cavities but rather controls the rate at which they develop making them take a lot longer and making them easier to prevent via normal brushing ...
Fluoride-containing toothpaste can be classified into two types, namely low-fluoride and high-fluoride toothpaste. [12] Low-fluoride toothpaste, depending on brand, generally contains 0.22% to 0.31% fluoride. [12] These fluorides are often manufactured in the form of sodium fluoride, stannous fluoride, or sodium monofluorophosphate (MFP). [4]
Tin(II) fluoride is added to some dental care products [111] as stannous fluoride (SnF 2). Tin(II) fluoride can be mixed with calcium abrasives while the more common sodium fluoride gradually becomes biologically inactive in the presence of calcium compounds. [112] It has also been shown to be more effective than sodium fluoride in controlling ...
Sodium monofluorophosphate is produced industrially by the reaction of sodium fluoride with sodium metaphosphate: [2] NaPO 3 + NaF → Na 2 PO 3 F. The process involves scission of a pyrophosphate bond, analogous to hydrolysis. SMFP can also be prepared by treating tetrasodium pyrophosphate or disodium phosphate with hydrogen fluoride. [2]
