Crown Lengthening Pain, Healing & Risks
Crown lengthening is a common periodontal procedure used to expose more of a tooth’s surface by reshaping gum tissue, and sometimes bone. It can be done for restorative purposes, such as preparing a tooth for a crown, or for cosmetic reasons, such as improving a “gummy” smile.
Like any surgery, it comes with considerations for comfort, recovery, and potential risks. Understanding what to expect helps you make an informed decision and plan for a smooth healing process.
Initial Expectations
The procedure is performed under local anesthesia, which means you should not feel pain during the surgery itself. You may, however, feel mild pressure as the periodontist works. Once the anesthesia wears off, discomfort is normal for the first few days.
Most patients describe the pain as moderate and manageable with over-the-counter pain relievers, though your dentist may prescribe something stronger if needed. Ice packs and keeping your head elevated can also help reduce swelling and soreness in the early stages.
Let the Healing Begin
Recovery from crown lengthening takes place in stages. In the first 24 to 48 hours, you may notice swelling and mild bleeding, which usually subside within a few days. Following post-operative instructions is critical at this stage. Your dentist will likely recommend avoiding hard, crunchy, or spicy foods and keeping the surgical area clean without brushing directly over it.
By the end of the first week, stitches are typically removed or dissolve on their own, and discomfort begins to ease. Many patients can return to normal activities within a few days, though you should avoid strenuous exercise for the first week to minimize bleeding and swelling.
Full soft tissue healing often takes six to eight weeks. In more complex cases, where significant bone reshaping was done, healing may extend to three or even six months. This longer timeline allows the gum line to stabilize before placing a final crown or restoration.
Possible Risks and Complications
Crown lengthening is generally safe, but no surgical procedure is without risks. Some possible complications include:
- Infection, which occurs rarely, but becomes vastly more likely if post-operative care instructions are not followed
- Increased tooth sensitivity, especially to hot and cold, which often improves over time
- Gum recession, which may expose more of the tooth root than expected
- Delayed healing, which can result from smoking, poor oral hygiene, or certain medical conditions
In very rare cases, changes in the bite or tooth alignment can occur if significant bone is removed. Your dentist will evaluate these risks before recommending the procedure.
Tips for a Smooth Recovery
The best way to minimize pain and reduce the risk of complications is to follow your provider’s care instructions closely. This may include using an antimicrobial mouth rinse, eating soft foods for several days, and attending all follow-up appointments. Maintaining good overall oral hygiene, without disturbing or re-injuring the affected area, also promotes faster recovery.
For most patients, the benefits of crown lengthening outweigh the temporary discomfort and risks. The procedure can make restorative treatments more effective, improve the appearance of your smile, and support better oral health in the long term. With proper care and patience, your gums can heal fully, setting the stage for a successful restoration and a lifetime of confident smiles.
