What Is Crown Lengthening?


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.


Benefits of Crown Lengthening



  • Improves tooth structure visibility for better restoration
  • Enhances smile symmetry and aesthetics
  • Helps maintain better oral hygiene in previously hard-to-reach areas
  • Reduces risk of gum disease by reshaping deep pockets

Procedure: How Crown Lengthening Are Applied



Initial Evaluation

The dentist examines your teeth, gums, and bone structure using X-rays.

Local Anesthesia

The area is numbed to ensure comfort during the procedure.

Tissue Removal

Excess gum tissue—and sometimes a small amount of bone—is removed

Shaping and Cleaning

The exposed area is shaped, cleaned, and sutured.


Healing Time

The gums typically heal within 1–2 weeks, but full recovery may take longer depending on the complexity.

Reasons for Crown Lengthening


Crown lengthening may be recommended for the following reasons:

  • To Restore Broken or Decayed Teeth When decay or damage extends below the gum line, crown lengthening makes the tooth accessible for proper restoration.
  • To Improve Smile AestheticsFor patients with a "gummy smile," this procedure can create a more balanced, attractive gum-to-tooth ratio.
  • To Support a Dental Crown or FillingAdequate tooth surface is needed for these restorations to bond properly and remain secure.
  • To Treat Gum DiseaseIn some cases, crown lengthening can help in treating periodontal issues by reshaping the gum tissue and bone.
