Inside your mouth, gum tissue forms a barrier that resists the vigorous mechanical (and microbial) effects of eating, chewing and biting. Gums may begin to recede, or shrink down, for several reasons.
One is ineffective oral hygiene: This includes both inadequate brushing, which fails to remove dental plaque; and excessive brushing, which erodes the tissue. Foreign objects in the mouth that rub against the gums, like poorly fitting removable dentures, tongue bolts, or even fingernails, can also contribute to gum recession.
When the tooth’s roots lose the protection of healthy gum tissue, they can become extremely sensitive to hot or cold temperatures, causing pain when you consume many foods and drinks. Worse, missing gum tissue makes it easier for bacteria to penetrate the roots and cause decay — or for minor trauma to result in rapid gum recession. In either case, the eventual result may be tooth loss. That’s why proper treatment of gum recession is so important.
After a thorough examination and assessment of your teeth, gums and overall health, the gingival grafting procedure may be recommended. The tissue used in this procedure may be obtained from a variety of sources: an area next to the area of recession, from the hard palate, or donated tissue from another person, which has been medically processed to make it safe to use.
There are several different methods of grafting. For example, if you have lost gum tissue in an area of your mouth that’s not highly visible when you talk or smile, additional gum tissue can be placed there to prevent further recession without trying to cover the tooth-root surface completely. This procedure is referred to as a free gingival graft (since the tissue is separated from its blood supply), and it takes about 45 minutes to perform. It is very predictable with a very high success rate. If the objective is to cover root surfaces, the procedure becomes more complicated and will take longer, but is still very successful.
Grafting procedures are typically carried out under local anesthesia, and are generally pain-free. You should experience very little discomfort after the surgery, even if tissue has been removed from your palate, because that donor area is usually covered by a soothing, liquid band-aid-like material. Fortunately, any discomfort that you do have can be alleviated with over-the-counter or prescription anti-inflammatory medication, and it is generally short-lived. A soft diet (and an antibiotic) may also be recommended for a week or so thereafter, enabling the tissues to heal fully; otherwise, your normal activities will not be limited.
