Crown Lengthening
Surgical dental procedure performed to expose more of the tooth structure by removing gum tissue and, if necessary, bone. This procedure is commonly done to prepare a tooth for a dental crown or to improve the aesthetics of a "gummy" smile, creating a well-proportioned and symmetrical smile.
Gum contouring
Crown lengthening, also known as a gum lift, is a procedure frequently used to treat a “gummy smile.” When excess gum tissue covers more of the teeth than is typical, teeth appear shorter and smaller.
During a gum lift, small areas of excess tissue are removed to reveal more of the tooth’s structure, making teeth look longer and more proportional. An uneven gum line can cause one or more teeth to appear misshapen or shorter than the rest, producing a “crooked smile.”
Gum contouring aesthetically reshapes the gum tissue for a natural-looking, even gum line.
Restorative crown lengthening
These procedures are also used in dental restorations exposing more of a tooth's structure to properly restore the tooth, for example veneers, or for teeth that have suffered injuries or serious decay near the gum line, a gum lift, or gum contouring can expose enough of the remaining tooth to support a crown. Contouring can be used with gum grafting to restore a gum line damaged by periodontal disease.
​
​After administering local anesthesia, the dentist makes incisions in the gum tissue to access the tooth and surrounding bone. Excess gum tissue and, if necessary, bone are then removed and the area is cleaned and stitched. Post-operative care instructions are provided, including pain management and oral hygiene practices. Follow-up appointments ensure proper healing before the final restoration, such as a crown or filling, is placed.

It's important to note that while this explanation provides a general overview of the crown lengthening procedure, specific details may vary depending on individual cases and the dentist's approach. Always consult with your dentist for personalized information and recommendations regarding any dental procedure
Procedure
Both crown lengthening and gum contouring are common outpatient procedures performed in your dentist’s office.
​
-
Your dentist will take a health history and assess your teeth, gums, and bone health, since gum disease or decay need to be treated before the procedure. You’ll discuss the outcome you desire and what to expect during and after surgery.
-
Before the dentist begins your procedure, local anesthetic will be used to numb the area. Sedation is also an option.
-
Your dentist will use hand-held tools or a laser to remove excess gum tissue. If necessary, a small amount of bone tissue around the tooth might be reshaped as well.
-
The gum tissue will be shaped, or contoured, around the base of the tooth or teeth to create an even, attractive gum line. Some small sutures might be needed to close, and a dressing applied.
-
You’ll be given directions for follow-up care to reduce swelling and bleeding, as well as instructions for how to brush, what to eat, and what to avoid as you heal. Your dentist might also prescribe antibiotics, an oral rinse, or pain medication.
-
Complete healing will take several months. You’ll have follow-up appointments with your dentist to monitor your recovery.
