Periodontal Disease is caused by bacteria which infect the periodontal lining of the gum. If not removed, this bacterial growth will spread and will begin to destroy the bone that supports the teeth.
As bone is destroyed by the bacteria that is found on plaque and calculus, pockets form between the teeth and gums. As these pockets become deeper, it is almost impossible to clean the bottom of the pockets using toothbrushing and flossing techniques. If the pockets are not adequately cleaned and debrided, they will continue to deepen and more bone will be destroyed.
This destructive cycle will continue and will eventually lead to tooth loss. The goal of all periodontal surgical procedures is to eliminate the pocket and to allow the patient to keep the gums and teeth clean using proper brushing and flossing techniques.
