Involuntary movements of the stomatognathic system, e.g., oromandibular dystonia or dyskinesia, can result in excessive involuntary muscle contractions in the mouth, jaw, tongue, and lips. These contractions can cause various symptoms including failure to chew foods, problems with mouth opening or closing, muscle pain, lateral shifting of the jaw, and difficulty in swallowing or speaking. We apply a comprehensive range of treatments including medication, injections of local anesthetic (muscle afferent block therapy) or botulinum toxin (Botox), and surgery, for such involuntary movements.
