But gums don't always let you know they are in trouble, even in the late stages of disease. Bacterial infection may be silently and progressively destroying the soft tissues and bone that support your teeth. Early diagnosis of periodontal disease, prompt treatment and regular checkups bring the best results. Periodontal disease is a serious and often ongoing condition, it requires an ongoing treatment programme to control it effectively. After a thorough evaluation, your periodontist will recommend the best course of professional treatment. Whether this means non-surgical or surgical treatment, it always includes home care. The periodontal therapy you get in the dentist's office takes care of the infection you have now and helps maintain control. But only you can provide the daily flossing, brushing and other care needed to prevent periodontal disease from getting worse or coming back. A periodontist is a specialist who specializes in the diagnosis, treatment and prevention of periodontal disease. In addition to four years of dental school, your periodontist has had extensive training in this specialty. He or she will provide you with treatment that ranges from deep cleaning of teeth and gums to surgical removal of infection to surgery that actually may restore soft tissue and bone, damaged by periodontal disease. Many periodontists also treat temporomandibular joint disorders (TMD), and are skilled in replacing missing teeth with dental implants.
