Crown lengthening is a periodontal procedure used to expose more of a tooth’s natural structure. For some patients, this treatment is recommended before placing a crown, filling, or other restoration. For others, it may be used to improve the appearance of an uneven or “gummy” smile.
At Your Gum Specialist in Forest Hills, Queens, crown lengthening is performed with careful attention to gum health, tooth support, and long-term restorative success.
What Is Crown Lengthening?
Crown lengthening is a procedure that reshapes gum tissue, and sometimes underlying bone, to reveal more of the visible tooth surface. This can create the space needed for a dental restoration to fit properly and remain stable.
The American Academy of Periodontology explains that crown lengthening may be used when a tooth needs to be exposed before restorative or cosmetic dental treatment. Learn more from the American Academy of Periodontology.
Why Crown Lengthening May Be Recommended
A periodontist may recommend crown lengthening when there is not enough exposed tooth structure above the gumline. This can happen for several reasons, including tooth decay, fracture, excessive gum coverage, or previous dental work.
- To prepare a tooth for a dental crown
- To expose decay or damage below the gumline
- To improve access for a filling or restoration
- To create a healthier gumline around a tooth
- To improve the appearance of short-looking teeth
Restorative Crown Lengthening vs. Cosmetic Crown Lengthening
Restorative crown lengthening is performed when a dentist or periodontist needs more tooth structure available to repair the tooth properly. This is common before placing a crown if decay or fracture extends close to the gumline.
Cosmetic crown lengthening is performed to improve the balance between the teeth and gums. Patients with excess gum tissue may appear to have shorter teeth, even when the teeth are normal in size.
The American Dental Association notes that periodontal procedures can help treat gum-related concerns and support long-term oral health when recommended as part of a broader dental plan. Learn more from the American Dental Association.
What Happens During Crown Lengthening?
Crown lengthening is typically performed with local anesthesia. During the procedure, the gum tissue is gently adjusted around the tooth. In some cases, a small amount of bone may also be reshaped to create the proper relationship between the gumline, bone, and tooth structure.
- The area is numbed for comfort.
- The gum tissue is carefully reshaped.
- Underlying bone may be adjusted if needed.
- The gumline is positioned to allow proper healing.
- Follow-up care is provided to monitor healing before final restoration.
How Crown Lengthening Supports Long-Term Dental Health
When a restoration is placed too close to the gum and bone, it may irritate the tissues or make the area harder to clean. Crown lengthening helps create the space needed for a healthier, more stable restoration.
The National Institute of Dental and Craniofacial Research emphasizes that periodontal treatment is focused on controlling infection and supporting daily care to maintain oral health. Learn more from the National Institute of Dental and Craniofacial Research.
Crown Lengthening and Gum Disease
Before crown lengthening is performed, active gum disease may need to be addressed. If inflammation, infection, or deep periodontal pockets are present, your periodontist may first recommend periodontal disease treatment or scaling and root planing.
Patients with more advanced periodontal disease may also be candidates for LANAP® laser gum surgery, depending on their diagnosis.
Recovery After Crown Lengthening
Most patients experience mild soreness, swelling, or tenderness after crown lengthening. Healing time varies depending on the extent of treatment and whether the procedure was performed for one tooth or multiple teeth.
After treatment, patients are typically advised to:
- Follow post-operative instructions closely
- Keep the area clean while avoiding irritation
- Eat softer foods during early healing
- Return for follow-up visits as recommended
- Wait until healing is complete before final crown placement
Why See a Periodontist for Crown Lengthening?
A periodontist specializes in the gums, bone, and supporting structures around the teeth. Because crown lengthening involves the relationship between the tooth, gumline, and bone, periodontal expertise is especially important.
At Your Gum Specialist, Dr. Krishnan and the periodontal team evaluate each patient’s gum health, tooth structure, and restorative needs before recommending treatment.

Frequently Asked Questions
Is crown lengthening painful?
Crown lengthening is performed with local anesthesia to keep the area comfortable. Some soreness or tenderness after the procedure is normal and usually temporary.

Initial healing may take a few weeks, but final healing before a permanent crown or restoration may take longer depending on the case.
Why do I need crown lengthening before a crown?
If there is not enough tooth structure above the gumline, crown lengthening can create the space needed for a crown to fit securely and avoid irritating the gum tissue.
Can crown lengthening improve a gummy smile?
Yes. In some cases, crown lengthening can reshape excess gum tissue and reveal more of the natural tooth surface for a more balanced smile.
