Muscle Relaxant Injections Treatment for Grinding/Clenching (Bruxism)

Bruxism is the medical term for involuntary teeth clenching and grinding, either while awake or asleep, which can lead to multiple problems.  Chronic teeth grinding can cause toothache, headache, earache, facial pain, and even trigger migraines. Dental problems from bruxism include loss of tooth enamel, increased tooth sensitivity, shortening, chipping/cracking and splitting of the teeth and restorations. Hypertrophy of the masseter muscle, which may lead to the appearance of a square jaw, is another side effect of bruxism. Treatments with muscle relaxant injections can provide considerable relief from jaw soreness, headaches, and other unpleasant problems associated with Bruxism. Muscle relaxant treatments for Bruxism can also soften the appearance of the jaw line.


Muscle relaxant injections vs. Conventional Bruxism Treatments

Recently, Muscle relaxant injections has proven to be an effective treatment option for targeting and treating excessive muscle activity and spasticity. Many other treatments, such as anti-inflammatory medications and dental splints, do not address the source of the problem. Although dental splints can successfully protect teeth from damage at night for bruxism sufferers, they are less effective in minimising the painful side effects of teeth grinding.


By injecting small doses of muscle relaxant directly into the Masseter muscle (the large muscle that moves the jaw), the muscle is weakened enough to stop involuntary grinding of the teeth and clenching of the jaw. This significantly relaxes the muscle and reduces the wear and tear on the teeth due to grinding. Damage to the TMJ (temporomandibular joint) and headaches can be reduced as well.  Voluntary movements, such as chewing and facial expressions, are not affected. The effect is temporary lasting 4-6 months.
