In-office methods

3. Tooth whitening toothpaste

  1. Before the procedure is started, the dentist should examine the teeth for any decay, gingivitis or teeth sensitivity.
  2. You should practice proper brushing and flossing. Regular brushing and flossing will keep the teeth white after the treatment
  3. Avoid dark staining foods and beverages like blueberries, coffee, red wine. Straw should be used for a little while after the procedure to avoid discoloration again. (3)
  4. Smoking or chewing tobacco should be stopped entirely to prevent discoloration.
  5. If the patient experiences sensitivity after the procedure, sensitivity toothpaste should be prescribed.
  6. Sugar intake in the diet should be limited as it supports the growth of cavity-producing bacteria which in turn could cause discoloration.
  7. A diet rich in calcium should be consumed, which strengthen the enamel and helps in keeping the teeth white. (4)
  8. Consumption of fruits and vegetables should be increased. The mechanical effect of chewing crunchy fruits and vegetables scrapes away the plaque present on the tooth surface.
