There's still much about the underlying nature of chronic jaw joint dysfunction we have yet to unravel. Treating these conditions known as temporomandibular joint disorders (TMDs) may therefore require some experimentation to find what works for each individual patient.
Most TMD therapies are relatively conservative: eating softer foods, taking anti-inflammatory pain relievers or undergoing physical therapy. There have been some surgical techniques tried to relieve jaw pain and dysfunction, but these have so far had mixed results.
Recently, the use of the drug Botox has been promoted for relieving jaw pain, albeit temporarily. Botox contains tiny amounts of botulinum toxin type A, a poisonous substance derived from the bacterium Clostridium botulinum, which can cause muscle paralysis. It's mainly used to cosmetically smooth out small wrinkles around facial features.
Because of these properties, some physicians have proposed Botox for TMD treatment to paralyze the muscles around the jaw to reduce pain and discomfort. While the treatment sounds intriguing, there are a number of reasons to be wary of it if you have TMD.
To begin with, the claims for Botox's success in relieving jaw pain have been mainly anecdotal. On the other hand, findings from randomized, double-blind trials have yet to show any solid evidence that Botox can produce these pain-relieving effects.
But even if it lived up to the claims of TMD pain relief, the effect would eventually fade in a few weeks or months, requiring the patient to repeat the injections. It's possible with multiple Botox injections that the body will develop antibodies to fight the botulinum toxin, causing the treatment to be less effective with subsequent injections.
Of even greater concern are the potential side effects of Botox TMD treatment, ranging from headaches and soreness at the injection site to more serious muscle atrophy and possible facial deformity from repeated injections. There's also evidence for decreased bone density in the jaw, which could have far-reaching consequences for someone with TMD.
The best approach still seems to lie in the more conservative therapies that treat TMD similar to other joint disorders. Finding the right combination of therapies that most benefit you will help you better manage your symptoms.
