During pregnancy, an expectant mother may crave for acidic food or vomit easily. These acidic food and vomit will erode the outer layer of the teeth (enamel) and expose the inner layer (dentine), resulting in tooth sensitivity.
If the expectant mother has no tooth decay or pulp inflammation, but feels sharp pain in her teeth which is triggered by hot, cold, sour or sweet food, or by toothbrushing and flossing, she may have got tooth sensitivity.
