Most people know BOTOX® Cosmetic as a treatment for facial wrinkles and fine lines. But for some people, BOTOX® may also relieve the chronic jaw pain associated with temporomandibular joint disorder (TMJ).
TMJ causes vary widely, and BOTOX® isn’t effective for everyone. In some cases, an oral appliance known as a bite splint may be recommended. BOTOX® may also be used in conjunction with other therapies, including bite splints. If you suffer from persistent jaw pain, recurring headaches and other TMJ symptoms, a knowledgeable neuromuscular dentist can recommend a treatment based on your unique needs.
BOTOX® in Brief
BOTOX® is the acronym for botulinum toxin A, which has a number of cosmetic and medical applications. The medical form is a serum that includes a small amount of the toxin to obstruct signals from the nerves to the muscles, thus prohibiting muscle contraction.
The serum is administered via a tiny needle to the affected site. In the case of forehead lines, for example, BOTOX® is applied to the muscles that cause the brow to furrow. In instances of TMJ, BOTOX® is injected into the lateral pterygoid muscles, which are on the upper portion of each side of the jaw and aid in chewing.
While BOTOX® is best known for its aesthetic applications, it has proven beneficial in treating migraines and a number of conditions characterized by muscle spasticity.
BOTOX® and TMJ
BOTOX® was approved by the FDA in 2002 for the treatment of glabellar lines, the “frown lines” that often appear between the eyebrows as we age. As such, research into BOTOX®’s applications for TMJ and other disorders is relatively recent and is still ongoing.
The findings of a study published in the November-December 2002 issue of the Clinical Journal of Pain suggested botulinum toxin could relieve TMJ-related orofacial pain, but it emphasized the importance of proper injection placement and technique in order to achieve results. In 2010, BOTOX ® was actually approved to treat migraines by targeting the same muscles that link TMJ to these chronic headaches.
A 2013 review of existing studies indicated that BOTOX® is effective in treating TMJ-related jaw pain. The same analysis found BOTOX® effective in treating chronic headaches and bruxism (teeth grinding), two conditions often associated with TMJ.
Other TMJ Treatments
BOTOX®’s effects fade with time, and repeat treatments may be necessary to maintain results. For TMJ, BOTOX® may be used as a complement to another therapy.
TMJ treatments differ depending on the source and severity of your condition. In addition to BOTOX®, other options include:
- TENS therapy: TENS stands for transcutaneous electrical nerve stimulation, and treatment consists of a mild electrical current delivered to the jaw muscles in order to relax the muscles and allow the jaw to settle into a comfortable resting position
- Oral appliances: These devices, often referred to as bite splints, are similar in style to sports mouthguards; they are custom made for each patient’s individual bite, and they are designed to hold the jaw in its optimal position
