Dr. Moskowitz may recommend osseous surgery when deep pockets have developed around the teeth. Ideally, the gums should adhere tightly around the teeth to prevent bacteria from penetrating the gumline. When toxic deposits from bacteria have weakened the gums, the soft tissue pulls away from the teeth. At first, the pockets that result from this recession are relatively shallow. They may be cleaned at home or with a minor professional cleaning. Over time, pockets caused by gum recession deepen, providing more space in which bacteria can accumulate. By reducing the depth of these pockets, osseous surgery can help reverse gum recession and prevent further damage to the periodontal ligament and bone that support teeth.
