Dental bridges are advanced dental work employing crowns to flank and support a false tooth which acts as a replacement for a lost or missing tooth. Preparation of the supporting or “abutment’ teeth is carried out by the dentist as for a crown, and following construction of the bridge by a dental technician, the crowns of the bridge can then be cemented permanently in place. The false tooth is suspended between the crowns with a small gap between its base and the gum surface, for cleaning. Dental bridgework can provide the finest and most comfortable method of replacing missing gum disease, full dentures are prescribed. These usually work well but the lower plate can become uncomfortable and difficult to control, resulting in ulceration of the mouth tissues. Gum ridges may become especially sore. To overcome this problem some tooth roots may be retained and initially trimmed to gum level to provide superior support and grip. Dentures made in this way are called overden-tures. If this is not possible then a soft lining on the fitting surface can do much to alleviate ridge soreness.
