Teeth may become sensitive as the gums recede, or as a result of breakage and wear. Heavily filled teeth are prone to fracture, and fillings may break and even fall out, causing sensitivity to cold, hot, or sweet things.

Treatment for tooth sensitivity in older people may involve managing receding gums, sealing over the fractured tooth surface, or treating the decay or broken tooth or fillings. Regular dental check-ups are important to spot and treat causes of sensitive teeth such as decay, broken teeth or fillings.
