Crown Lengthening: Reshaping the Gum Line
Crown lengthening is a surgical procedure that exposes more of the existing tooth by reshaping or repositioning the gum and, where necessary, removing some supporting bone. It may be considered to help restore a damaged tooth or, in selected cases, change the gum line for appearance reasons. Removal of gum or bone tissue is irreversible. Suitability depends on an individual assessment of the teeth, gums and supporting structures.
Crown Lengthening: Benefits and Considerations
Surgical Procedure: Treatment involves reshaping or repositioning the gum and may include bone removal. Possible risks include pain, swelling, bleeding, infection, tooth sensitivity and permanent changes to the gum line. The final appearance may differ from the planned result.
Aesthetic Change: It can change the appearance of the teeth, and results vary between patients.
Restorative Support: In suitable cases, the procedure can expose more existing tooth structure to help a dentist place a filling or crown. Whether the tooth can be restored depends on its overall condition.
Personalized Design: The surgical plan is tailored to the specific needs of each patient.
Frequently Asked Questions
Who is a suitable candidate for crown lengthening?
Crown lengthening may be considered when more tooth structure needs to be exposed for a filling or crown, or in selected cases where a person wishes to change the appearance of the gum line. Short-looking teeth or a gummy smile do not automatically mean surgery is appropriate. Gum inflammation around an existing restoration should first be assessed to identify its cause. Your dentist will assess your oral health and discuss suitable options, their risks, costs and alternatives, including no treatment where appropriate. Referral to a periodontist may be recommended.
What does crown lengthening involve, and what is recovery like?
Crown lengthening is usually performed under local anaesthetic. The extent of surgery depends on the tooth and surrounding tissues, and stitches may be needed. Pain, swelling, bleeding and sensitivity can occur after treatment. Healing varies, and the gum line may continue to change during recovery. Where a filling or crown is planned, further healing time may be needed before the final restoration is placed. Your dentist will explain the proposed procedure, individual risks, aftercare and follow-up requirements before you decide whether to proceed.
