The alveolar bone is the most active part of the bone that changes gradually as the teeth in the mouth grow and develop and are replaced. Congenital heredity and acquired open-mouth breathing, etc. may lead to protruding alveolar bone, which needs to be examined in dentistry and treated according to the severity of the protruding alveolar bone. Common causes and treatments are as follows: Protruding alveolar bone may be due to congenital inherited growth and development deformities, which means that there are invisible or dominant genes in the parents that cause protruding alveolar bone. During acquired dental growth, frequent breathing through the mouth causes the jawbone to move forward, which may cause the alveolar bone to protrude as it is constantly stimulated during occlusion. Wrong way of breastfeeding during infancy and loss of individual teeth during tooth replacement lead to jawbone deformity, which may also eventually lead to alveolar bone protrusion. Acquired trauma, such as tooth extraction, surgery, and impact may also lead to misaligned protruding alveolar bone. Mild alveolar bone protrusion can be gradually corrected back to its original position by orthodontic treatment, or the deformity can be restored by tooth extraction. Severe alveolar bone protrusion or bony patients are usually treated with combined orthodontic and orthognathic treatment or orthodontic masking treatment. Alveolar bone protrusion can affect normal chewing, oral closure and speech, and may also have a certain impact on facial appearance, which in turn affects psychological health and normal life, so patients are advised to actively cooperate with treatment. In addition, it is recommended that patients pay attention to maintaining oral hygiene in daily life, insist on brushing teeth in the morning and evening, and minimize the consumption of hard and stimulating food to avoid harming the alveolar bone.
