A periodontist is a dentist who has received extensive training in the prevention and treatment of gum disease. They have advanced training in dental implants which are capable of replacing missing teeth or securing loose dentures.
Periodontal (gum) disease attacks the soft tissues and bone that forms the "foundation" of your teeth. It is the major cause of tooth loss in adults. Because this process is often painless, it may go unnoticed. This is why good daily oral hygiene and regular dental check-ups are important.
