Dentists always aim to preserve natural teeth whenever possible, choosing restorative treatments like fillings and crowns over extractions to maintain optimal oral health, function, and aesthetics. However, when a tooth is severely decayed or damaged below the gum line, traditional restorations may not provide enough support for long-term success. In these situations, crown lengthening becomes an effective and reliable dental procedure.

Crown lengthening is a common surgical treatment that reshapes and recontours the gum tissue — and in some cases the underlying bone — to expose more of the tooth structure above the gum line. Although the procedure does not actually lengthen the tooth itself, it lowers the surrounding gum tissue to create adequate space for placing a durable dental crown.
