When advanced gum disease (periodontitis) develops, your teeth are in danger: At this stage, the ligaments and bone tissue that surround them are being destroyed, and you could even begin losing teeth! If the disease can't be controlled by non-surgical treatments like cleaning and scaling, then periodontal flap surgery may be your best treatment option.

Flap surgery is today's leading method for treating and repairing periodontal pockets. What are these “pockets?” They are areas below the gum line where gum tissue has detached from the teeth, resulting in an uncleansable space where harmful bacteria can proliferate. These bacteria cause inflammation of the tissues, resulting in sensitivity, bleeding, and pain. Left untreated, they can cause a host of problems including gum disease, loss of the tooth-supporting bone structure, and possibly even systemic (whole-body) problems.

When periodontal pockets develop, the first step in treating them is usually via cleaning and scaling (also referred to as root debridement) with a manual or ultrasonic instrument. If this isn't effective, then periodontal surgery is considered. Flap surgery isn't a cure for periodontal disease — but it helps create an environment that makes it easier to maintain your periodontal health. And even if you're prone to gum disease, proper professional treatment and regular care at home can help keep your teeth healthy for as long as possible.

The Goals of Flap Surgery

One major objective of flap surgery is to eliminate or reduce the pocket itself. To access it, a flap-like incision is made in the gum tissue. This allows diseased tissue to be removed from inside the pocket, and provides access to the teeth's root surfaces for a thorough cleaning, which helps to eliminate harmful plaque and calculus (tartar). Afterward, the “flap” is closed, sealing the area. This begins the healing process, which takes place rapidly.

Another goal is the regeneration of periodontal ligament and bone tissue which may have been lost to the disease. A variety of techniques may be used to accomplish this, including high-tech methods of bone grafting and chemicals referred to as growth factors. These approaches help restore the gums to their normal form and function, and promote the healthy and secure anchoring of teeth.

The Flap Surgery Procedure

• Flap surgery is typically done under local anesthesia, sometimes accompanied by oral anti-anxiety medications; alternatively, it may be performed under intravenous conscious sedation. After anesthesia has taken effect, a small incision is made to separate the gums from the teeth. The outer gum tissue is gently folded back to give access to the roots and the supporting ligament and bone tissue.

• Next, the inflamed gum tissue can be removed, and the tooth roots can be cleaned; if needed, the area may also be treated with antibiotics or other medications. Bone defects can be repaired with grafting material, and proper regeneration of the periodontal ligament can be encouraged by physical (barrier membranes) and chemical (growth factors) methods. Finally, the incision is closed and the procedure is completed.

• Performed by an experienced hand, state-of-the-art flap surgery has an excellent track record and offers well-established benefits. It's often the treatment of choice for relieving periodontal disease and helping to maintain your oral health — and preserve your teeth.
