Tooth Decay

People with reduced saliva secretion (Dry mouth)

These include:

  1. People who are taking medications such as anti-hypertensive and anti-depressant drugs.
  2. People who have received radiotherapy in the head and neck area.
  3. People with general health problems such as Sjogren’s Syndrome and autoimmune diseases.

Since these people do not have enough saliva to neutralize the acid produced by bacteria after eating and drinking, their chance of having tooth decay will be increased.

Dietary habits of pregnant women may change and they tend to prefer sweet and sour food. The frequency of meals may also increase during pregnancy, which results in a higher risk of getting tooth decay.
