Jaw reshaping or jaw reduction treatment is a surgery done to narrow the lower the jaw from the mandible and its muscular attachments. There are both surgical and non-surgical treatments for jaw reshaping. A dentist would be the best person to evaluate and analyse the kind of treatment that would be best suited for a person who needs to have jaw reshaping. People with misshapen jaws are usually the candidates for having jaw reduction or jaw shaving. Widening the jaw can either bring a square appearance to the face or distort the natural appearance of the angle between the chin and neck. A wide lower jaw is usually due to the enlargement of the mandible or masseter muscle. This could be a congenital condition also. It can also be commonly acquired deformity due to excessing chewing of gum or teeth clenching. A dentist would be able to suggest the right kind of treatment for jaw reshaping either, surgical or non-surgical. However, both treatments can be expensive. Non-surgical methods include botox injections, which are mostly for cases in which the jaw is enlarged. Botox is injected into the enlarged muscles and slowly weakens the muscle over a long period of time. Improvement will not be seen for two to three weeks. It may take up to one year for visible improvement. The other technique is surgical reduction of the enlarged mandible. Mostly internal incision is made so that there are no visible scars.
