Esthetic Crown Lengthening
Periodontal procedures are available to lay the groundwork for cosmetic dentistry - to enhance and improve the esthetics of ones' gumline thus improving their smile.
If too much "gum" covers the crown of the teeth, the smile will appear "gummy" and ill-proportioned to the length of the teeth. To correct this, excess gum and bone tissue is reshaped to expose more of the natural tooth. This procedure is also done to correct an uneven gumline.
Functional Crown Lengthening
When crown lengthening is done to facilitate repairing or restoring a tooth or teeth, it is done for function. In preparing or fitting a "cap" or "crown", this crown lengthening procedure provides the necessary space between the supporting bone and crown, preventing the new crown from damaging gum tissues and bone. Also, if a tooth is damaged or decayed below the "gumline", crown lengthening allows the tooth to be restored by exposing more workable surface to accomplish the goal.
