Oral & Maxillofacial surgery (OMS) is a specialized form of dentistry that concentrates on the treatment of disease and damage to the head, neck, face, jaws and teeth. The dentist who is performing Oral or Maxillofacial surgery is performing procedures which repair both hard and soft tissues in the mouth, face and jaw. The specialization is recognized worldwide, but in the United States an Canada it is considered specifically as an area of dentistry. In other parts of the world, it is considered more of a dual specialty of medicine and dentistry.

One of the main areas of concentration within the Oral and Maxillofacial surgery specialty is the diagnosis and treatment of oral cancer. Through screenings and exams designed to diagnose oral cancer as early as possible, the dentists of Portola Dental Group are able to begin treatment for oral cancer earlier in the process than if it is un-diagnosed and is noticed after complications begin. Early diagnosis gives a far better chance of success than late diagnosis, and treatments for diseases like this one vary from patient to patient. In the case of oral cancer, it is crucial to have necessary dental work completed previous to radiation treatments, as the effected saliva production can cause serious detrimental effects that can lead to jaw bone disintegration and tooth loss
