Tooth Deacy

  1. 1. Tooth Decay Chapter: Food and Nutrition Made By: Momina Rehan
  2. 2. Definition:  Erosion of enamel and the dentine is known as “Tooth Decay”.
  3. 3. Stages of Tooth decay:  The major reason is dental plaque which is a sticky substance consisting of food, mucus and bacteria.  Dental plaque covers the teeth as a hard layer.
  4. 4.  Bacteria present in the plaque produce an acid which gradually destroys the enamel and makes a hollow cavity in it.
  5. 5. Causes of Tooth decay:  Improper brushing or not brushing causes a hard layer of plaque to develop over teeth.  Eating too much sweet , candies and chocolates also cause the bacteria to grow in the plaque.
  6. 6.  The bacteria feeds on leftover sweets and produce the acid that causes tooth decay.  If this decay is ignored, the erosion penetrates deep to destroy the dentine.  After destroying the dentine bacteria infects the pulp which results in tooth ache and the tooth gradually destroys.
  7. 7. Prevention:  Proper brushing can prevent tooth decay.  Use of a fluoride based tooth paste makes the tooth strong.  Cutting down sugary diet is also prevention against tooth decay.  Regular dentist visit ensures the health of teeth.
