➔ Tooth decay starts when the pH of the mouth is lower than 5.5 Tooth enamel made up of calcium hydroxyapatite (a crystalline from of calcium phosphate) is the hardest substance in the body .It does not dissolve in water ,but is corroded when the pH in the mouth is below 5.5 . Bacteria present in the mouth produce acids by degradation of sugar and food particles remaining in the mouth after eating .The best way to prevent this is to clean the mouth after eating food . Using Toothpaste ,which are generally basic ,for cleaning the teeth can neutralise the excess acid and prevent tooth decay.
