    Teeth sensitivity develops between the age group of 25 and 30.

    Use of a hard-bristled toothbrush also causes sensitive teeth due to the enamel and gum tissue damage.

  • Poor oral hygiene:

    This is the major cause of sensitive teeth in most people. It leads to build-up of plaque, tartar or calculus, which causes gum or periodontal disease and receding gums.
