Using a softer bristle brush and brushing less vigorously is your best course. Brushing too vigorously can erode the hard protective layer on the teeth. Don’t brush too soon after eating or drinking; use a soft-bristled toothbrush. Once enamel is worn away, it cannot be replaced and can lead to tooth discoloration and decay.

Chipped or Cracked Teeth

If you have a chipped or cracked tooth and notice pain resonating from that particular tooth, this is a severe condition and one of the top causes of sensitive teeth. The discomfort experienced most likely results from plaque and food debris seeping into your teeth, accessing the pulp, and causing an infection. Extraction, a root canal, or another dental procedure must be done to treat the disease and alleviate the pain. In addition, cavities can weaken the teeth and predispose you to chipped teeth.
