    ReputationRep:
    Plaque builds up on your teeth (a sticky colourless film of bacteria and sugars)
    Acid is produced by the bacteria
    This acid eventually dissolves/weakens the enamel of your tooth
    Eventually a cavity is formed in the hard enamel layer of your tooth
    This cavity allows bacteria to enter the softer dentine inside your tooth, causing further damage and decay to the tooth.

    Prevention: brush twice a day, floss between teeth, reduce sugar in your diet, use mouthwash, visit a dentist regularly, healthy diet including calcium and vitamin D for strong teeth.
