The alveolar bone refers to the lower edge of the maxilla and the upper edge of the mandible that wraps around the roots of the teeth. Alveolar bone growth is a hard tissue similar to the teeth that protrudes from the inside or outside of the teeth. There are many causes of alveolar bone hyperplasia, but the main ones are: (1) Chronic inflammation caused by prolonged stimulation of chronic inflammation such as periodontitis, periapical inflammation, and local marginal bone marrow inflammation, which may lead to alveolar bone hyperplasia, which is the most commonly seen cause. (2) Trauma or compression factors can lead to alveolar bone hyperplasia, orthodontics may perform extractions and wear braces, and improper braces produce abnormal orthodontic forces that stimulate alveolar bone hyperplasia. (3) Causes of overdevelopment. (4) Genetic factors, this type of alveolar bone hyperplasia belongs to the family. (5) Drug causes. Some hormonal drugs can cause bone hyperplasia, including alveolar bone hyperplasia. (6) Viral factors. (7) Age factor. Many elderly people, after losing their teeth, still use their gums to chew food, which leads to alveolar bone enlargement. Alveolar bone enlargement usually does not cause pain to the patient, nor does it cause facial changes, and most of them do not need to be treated. It is a common symptom of bone enlargement, and if there is no abnormal feeling, most of them do not need to be treated.
