Periodontal flap surgery, or pocket depth reduction, is a treatment that, as the name states, is offered to help reduce the depth of the periodontal pockets. These pockets are between the visible gum line and the gum attachment to the surface of the tooth – they indicate the level of gum health in your oral cavity. This treatment will help the gum re-attach to clean root surfaces, and to reduce periodontal pockets. During flap surgery the doctor will surgically expose the root surfaces, so that scaling and root planning is possible by direct vision. The calculus (tartar) covered and infected tissue areas will be debrided and the bone examined. Dr. Yuen will make sure that the area is perfectly and carefully cleaned to ensure a successful healing process. We will make sure that you’re comfortable, relaxed and experiencing no-to-minimal pain. We’ll also make sure that you’re following the right instructions and hygiene habits to avoid future formation of pockets .
