A TMJ splint can be one of several different types of
orthodontic devices that are used to help relieve the pain
associated with temporomandibular joint disorder (TMJ). TMJ splints
are typically mouth guards that are fitted by a dentist and worn
over the top or bottom teeth. These mouth guards are normally made
of hard acrylic and can be worn at night, during the day, or
continually depending on the needs of a particular person. It is
important that the TMJ splint is fitted properly to avoid
aggravating the patient’s jaw strain.
TMJ causes pain in the temporomandibular joint, located in front of the ears on each side of the head. There are many different causes of TMJ pain, including arthritis and muscle fatigue that results when the teeth are clenched or ground constantly. The vast majority of TMJ cases can be managed without significant medical intervention.
A TMJ splint is an artificial bite that helps protect the teeth and jaw from damage and strain. Nightguard, bite guard, and mouthpiece are other common names for the splint. All of these devices are the same. The only difference for dental professionals is when they are worn; a nightguard, for instance, is worn only at night, while a splint is never removed from a person’s mouth.
When making a TMJ splint, a dentist will begin by making an impression of the person’s mouth by using dental putty or similar material. The impression is then allowed to set before being sent to a lab where a custom splint is made. It can take several weeks for the TMJ splint to be made by the lab and fitted and adjusted by the dentist.
The most effective TMJ splints are made and fitted by dentists. A dentist is able to sand a splint to ensure that it will be comfortable and effective for the patient. A TMJ splint can also be purchased over the counter or through the mail. Boil and bite splints can be purchased in stores and are made of a thermo plastic material that molds more closely to a patient’s teeth after being boiled and placed in the mouth. It is possible that ready-made and boil and bite splints will not fit as well as those made by a dentist.
Any device that is worn in the mouth for prolonged periods of time must be cleaned routinely to avoid infection. A TMJ splint can become warped if it is not stored properly, resulting in increased pain. The dentist will provide care and cleaning instructions for the splint and may recommend follow-up exams to monitor a patient’s progress.
