Guided Tissue Regeneration (GTR) is a procedure that enables bone and tissue to regrow around an endangered tooth. This is different from other periodontal therapies where regrowth of the bone and the tissue is often limited or highly unpredictable. Conventional therapies may also involve removal of gum tissue to reduce pocket depths. This can leave a greater portion of your tooth exposed, resulting in a less pleasing appearance. 

In GTR therapy, the gum is surgically separated from the endangered tooth and the tooth surface is thoroughly cleaned. Infected tissues are removed from the area. Next, a small piece of material called a GTR membrane is placed against the tooth. The gum is then sutured back into place, covering the membrane. Within a few days, the healing process begins.
