A person wishing to restore a decayed tooth or broken tooth going underneath the gums will often need a tooth crown lengthening procedure prior to making a dental crown. When a tooth breaks underneath the gums, more tooth structure is needed for the crown to grab on to. The gum tissue is gently reflected and a small amount of bone is removed to expose more healthy tooth structure. You will have a temporary crown for 6 weeks while your gum tissue heals. This ensures optimum long-term stability for your new porcelain crown. The procedure is performed in our office by our periodontist, under local anesthesia.
