Muscle relaxers in the Masseter Muscle used for chewing can assist with facial slimming and reduction on clenching and grinding. Clenching and grinding of the teeth is a common problem affecting up to 30% of people and usually occurs during sleep. It is believed to be due to an abnormal bite or missing or crooked teeth. Daytime bruxism may be increased by stress and anxiety.
Bruxism can result in headaches, aching jaw muscles and hypersensitive teeth. Over time it may cause wear and even breakage of teeth, requiring crowns, fillings, and implants.
This condition can be significantly improved with the use of a muscle relaxer injected into the masseter muscle. Many people prefer this to wearing a night splint, however I recommend continuing to wear the night splint to protect the teeth and reduce the surrounding muscle spasm. Treatment usually lasts 4 to 6 months. I find the frequency and dose required reduces over time.
Treatment of the masseter muscle also reduces the bulk and size of the muscle resulting in a slimmer appearance to the lower face.
The standard dose for treating bruxism is 40 units of the strongest muscle relaxer.
