They contain Fluoride Compounds such as Sodium Fluoride (NaF), Stannous Fluoride (SnF2), or Monofluorophosphate (MFP2) etc. If the fluoride content is 1,000 ppm (parts per million) or above. they are all effective in preventing tooth decay.Children toothpaste contains 500ppm fluoride and is usually flavoured, e.g. fruit flavour, candy flavour, which is more appealing to children.
The active ingredients provide relief from dentine hypersensitivity symptoms in 2 ways. First, they interrupt the neurone response to pain stimuli; second, they occlude the dentinal tubules of dentine. Active ingredients such as Potassium Nitrate or Arginine, etc., are used by different product manufacturers. There are many different types of desensitizing toothpastes marketed by different brand names. Their various functions depend on different active ingredients they contain. Therefore, you are advised to consult the dentist and undergo a thorough check-up to explore the cause of tooth sensitivity before using desensitizing toothpaste. You should consult the dentist if the symptoms of tooth sensitivity persist after using desensitizing toothpaste.
The manufacturer claims that the calcification of dental plaque could be retarded by this kind of toothpaste, thus it reduces the rate of calculus formation. The active ingredient is Pyrophosphate or Zinc Citrate, etc.
This kind of toothpaste inhibits plaque accumulation, reduces the toxic effects of the bacterial toxin on the tooth surrounding tissues, thereby reduces the chances of getting gum disease. In the market, different anti-plaque toothpastes contain different active ingredients. For example, Triclosan or Zinc Citrate, etc.
This kind of toothpaste contains relatively coarse abrasives which function by abrading the stains on the tooth surface, giving a whitening effect. The effects of the long term use of this kind of toothpaste are still unknown.
