The worst outcome of periodontal (gum) disease is tooth loss—but it isn't the only form of misery you might suffer. One of the more troublesome results associated with gum disease is gum recession.
Normal gum tissue covers teeth from just above the visible crown to the roots, providing protection against bacteria and oral acid similar to the enamel on the crown. But advanced gum disease can weaken these tissues, causing them to pull away or recede from the teeth.
Not only can this diminish your smile appearance, but the exposed areas are more susceptible to further disease and painful sensitivity. And it certainly can accelerate tooth loss.
But there are some things we can do to reduce the harm caused by gum recession. If we're able to diagnose and treat a gum infection early while the gums have only mildly receded, the tissues could stabilize and not get worse.
The chances for natural regrowth are unlikely, especially the more extensive the recession. In such cases, the gums may need some assistance via plastic periodontal surgery. Surgeons reconstruct gum tissues by grafting like tissues to the area of recession. These grafts serve as a scaffold for new tissues to gradually grow upon.
There are two general types of grafting procedures. One is called free gingival grafting. The surgeon completely removes a thin layer of skin from elsewhere in the mouth (such as the palate), then shapes and attaches it to the recession site. Both the donor and recession sites heal at approximately the same rate, usually within 14-21 days. This procedure replaces missing gum tissue, but doesn't cover exposed tooth roots to any great extent.
In cases of root exposure, dentists usually prefer another type of procedure, known as connective tissue grafting. The donor tissue is usually taken again from the palate, but the design of the surgery is different. A flap of tissue at the recipient site is opened so that after the connective tissue from the palate is placed at the recipient site to cover the exposed roots, the flap of tissue covers the graft to provide blood circulation to the graft as it heals.
Both kinds of procedures, particularly the latter, require detailed precision by a skilled and experienced surgeon. Although they can successfully reverse gum recession, it's much better to avoid a gum infection in the first place with daily oral hygiene and regular dental care.
