Bruxism is a disabling condition in which unconscious contractions of the masticulatory muscles lead to teeth grinding and jaw clenching. Symptoms include toothache, temporomandibular dysfunction, headache and attrition. Treatment options range from conservative approaches to invasive interventions. Education, stress reduction, avoidance of stimulants, and relaxation techniques can help in mild cases. Wearing an occlusal splint can reduce attrition. Botulinum neurotoxin type A (BoNT-A) injections are a treatment option temporarily causing partial paralysis of the masticulatory muscles. BoNT-A is a treatment for reducing symptoms and improving the quality of life of patients with bruxism that has been proven safe and effective. The effects usually last several months. To achieve the best results and minimize side effects, BoNT-A injections should be applied by an experienced practitioner.

Temporomandibular Disorders (TMD) is a collective term embracing a number of clinical problems that involve the muscles of mastication, the temporomandibular joint (TMJ) and associated structures or both. This group of disorders has been identified as the chief cause of pain, which is not of dental origin, in the orofacial area, and is defined as a subgroup in the category of musculoskeletal disorders. These disorders impair the quality of life of those suffering from them due to the extent of the pain and the chronic nature of its symptoms.
