A large number of DH cases are linked to periodontal disease and follow as a result of periodontal treatment. Surgical and non-surgical periodontal treatment is said to have the same effect on DH. As part of the periodontitis disease process, recession and root exposure are prevalent. The aim of periodontal treatment is to reduce the inflammation that presents. Treatment strategies also lead to the removal of cementum, smear layer and exposure of dentinal tubules, furthermore causing DH for patients. Within the elderly generation periodontal disease is more prevalent however, DH is not a common diagnosis in the elderly. DH decreases during 40–50 years, a plausible explanation or this is the result of sclerosing of canals and formation of tertiary dentine.
