Why does teeth grinding or bruxing cause TMD?
Teeth grinding, or bruxing, places pressure on the muscles, tissues and supporting structures of the jaw, causing pain and joint dysfunction.
How is TMD diagnosed?
Whilst identifying TMD can be difficult, a conclusive diagnosis is made through comprehensive review of a patient's medical history, along with physical examination and medical imaging if required.
How is TMD treated?
Treatments can include; medication, appliance therapy (splints & mouthguards), occlusal equilibration (reshaping the bite), laser therapy, Myotherapy and orthodontia or Maxillofacial Surgery
Will I need surgery for my TMD?
