There are various reasons for root exposure, such as ageing, improper brushing, poor oral hygiene, irritants that irritate the gums for a long time, thin bone plates on the labial and buccal sides of the alveolar bone, patients undergoing orthodontic treatment, etc. can cause damage to the alveolar bone, which can lead to root exposure.
In addition, prolonged untreated apical inflammation developing into osteomyelitis of the jaw, which destroys the alveolar bone at the root tip, can also lead to root exposure.
