Thin alveolar bone carries some risk for tooth extraction. Most people’s alveolar bone is of moderate or thin thickness, and tooth extraction carries certain risks, such as fracture of the alveolar bone, which can cause swollen and painful gums, bleeding, or difficulty in biting. Therefore, whether the thin alveolar bone is specifically extracted or not needs to be analyzed in detail. Generally speaking, the bone remodeling ability of teenagers is relatively strong, even if the alveolar bone is thin, you can be assured that the teeth can be extracted for correction. If an adult has thin alveolar bone, an oral CBCT will be performed to measure the thickness of the alveolar bone through the image, and then determine whether the direction of tooth movement is toward the thin alveolar bone side. If the direction of tooth movement is not in the same direction as the thin alveolar bone side, extraction can be considered. Therefore, if the thin alveolar bone needs to be extracted, it is recommended to go to the stomatology department of a regular hospital to have a professional dentist conduct professional examination, judgment and analysis before determining whether or not the tooth can be extracted, so as to try to avoid the risk of tooth extraction.
