Treatment
Treatment depends on the cause of trismus. It usually involves doing exercises several times a day. A device may be used to gradually open the mouth. More severe cases may require physical therapy and muscle relaxants. In select cases, minimally invasive surgery may be helpful. Treatment should begin as soon as possible to prevent trismus from getting worse. Some cases will get better within a week. Others may last for several months.
