Ridge augmentation is a common procedure performed to help recreate the natural contour of the gums. Often, after a tooth is removed, the bone in the jaw will begin to deteriorate and recede. The height and width of the socket, which was supported by the tooth, will begin to shrink after the loss of the tooth. Many patients will eventually develop an indentation in the gums where the tooth used to be as a result of tooth and bone loss. Restoring the natural contour of the gums is not usually medically necessary. It is often recommended when a large depression or cleft exists in the gum tissues, which can trap food and bacteria. Ridge augmentation is frequently performed for aesthetic reasons, as the ridge is a very important structure in the mouth. Another purpose of ridge augmentation is to increase the amount of gum tissue in areas of deficit for tooth replacement, so that the teeth appear to rise from the gum tissues. This procedure may be necessary in order to place a dental implant. If the bone tissue has deteriorated too much, placing a dental implant may not be possible without an additional procedure.
