How are protruding teeth formed?

There are several causes of protruding teeth, including genetic factors,不良 oral habits, functional occlusion problems, nutritional deficiencies, and periodontal disease. Genetic factors refer to an increased likelihood of developing protruding teeth if parents or ancestors had the condition. Poor oral habits, such as prolonged finger-sucking, biting pen caps, or mouth breathing, can lead to abnormal development of the upper and lower jawbones, resulting in protruding teeth. Additionally, nutritional deficiencies and periodontal disease may also affect the normal growth and development of facial bones and soft tissues, increasing the risk of protruding teeth.
