Crown Lengthening

What Is Crown Lengthening?

Crown lengthening is a minor oral surgery procedure that reshapes the gum tissue and sometimes the underlying bone to expose more of a tooth’s structure. This is commonly done when a tooth is broken below the gumline, has decay under the gums, or when a crown or filling cannot properly fit without additional exposed tooth surface.

Why Crown Lengthening May Be Needed

Your oral surgeon may recommend crown lengthening for several reasons:

A tooth is broken at or below the gumline
There is decay underneath the gum tissue
A crown or filling needs more exposed tooth structure for proper fit
Uneven gum line affecting smile aesthetics
Preparation for restorative dental work

Benefits of Crown Lengthening

Crown lengthening can:

Help save a tooth that might otherwise need extraction
Improve the success and longevity of crowns or fillings
Create a healthier gum-to-tooth ratio
Enhance cosmetic appearance of the smile
Reduce irritation caused by deep decay or broken teeth

What to Expect During the Procedure

Crown lengthening is typically performed in-office under local anesthesia, with optional sedation depending on patient needs.

Step-by-Step Overview:

The area is numbed for comfort
The gum tissue is gently lifted away from the tooth
Small amounts of gum and/or bone may be reshaped
The area is cleaned and sutured
Healing begins immediately after the procedure

The procedure usually takes about 30–90 minutes depending on complexity.

Recovery and Healing

Most patients experience mild discomfort for a few days following surgery.

Common post-operative effects:

Mild swelling
Soreness at the surgical site
Sensitivity to temperature
Minor bleeding for the first 24 hours

Recovery tips:

Take prescribed or recommended pain medication as directed
Eat soft foods for the first few days
Avoid brushing directly on the surgical site initially
Rinse gently with salt water or prescribed rinse
Avoid smoking or using straws during healing

Healing typically takes 1–3 weeks for soft tissue, with full stabilization taking a bit longer depending on bone involvement.

Is Crown Lengthening Painful?

The procedure itself is not painful due to anesthesia. Most patients report only mild discomfort during recovery, which is manageable with medication and proper aftercare.

Risks and Considerations

As with any surgical procedure, there are some risks, including:

Temporary sensitivity
Gum recession changes
Infection (rare with proper care)
Uneven gum contour during healing

Your surgeon will review your individual risk factors before treatment.
