Crown lengthening is a dental procedure that reshapes the gum tissue—and sometimes bone—to expose more of a tooth’s surface. It is often recommended for patients who have a “gummy smile,” a tooth that is broken below the gum line, or insufficient tooth structure for placing a crown or filling. This procedure can be performed for cosmetic or restorative purposes.
Crown lengthening involves removing a small amount of gum tissue, and in some cases, underlying bone, to lengthen the visible part of the tooth. This creates a healthier and more aesthetically pleasing gum line while improving access to decayed or broken areas of a tooth for restoration.
The dentist examines your teeth, gums, and bone structure using X-rays.
The area is numbed to ensure comfort during the procedure.
Excess gum tissue—and sometimes a small amount of bone—is removed
The exposed area is shaped, cleaned, and sutured.
The gums typically heal within 1–2 weeks, but full recovery may take longer depending on the complexity.
Crown lengthening may be recommended for the following reasons:
No, the procedure is performed under local anesthesia. Some mild discomfort is expected afterward, which can be managed with over-the-counter or prescribed pain relievers.
Initial healing takes about 1–2 weeks, but full healing of the gums can take a few months.
No, the gum typically does not regrow to its original position after crown lengthening.
Yes, crown lengthening results are long-lasting, especially when paired with good oral hygiene.
You should eat soft foods and avoid hot, spicy, or crunchy items for a few days to aid healing.
