What Is Gum Contouring?
Gum contouring is a surgical procedure that removes or reshapes gum tissue to change the shape of your gum line. It is also called gum reshaping, tissue sculpting, or gingivectomy (the surgical removal of gum tissue). A closely related procedure, gingivoplasty, specifically refers to reshaping the gum tissue to create a more natural contour. [6]
Some people have gum tissue that sits too high on the teeth, making teeth look long or exposed. Others have gum tissue that sits too low, covering part of the tooth and creating what is sometimes called a "gummy smile." Gum contouring corrects both of these situations. The procedure can be performed on a single tooth, several teeth, or the entire gum line.
Gum contouring serves both cosmetic and functional purposes. On the cosmetic side, it creates a more even, balanced gum line. On the functional side, it can expose hidden tooth structure that a dentist needs to place a crown, filling, or other restoration. Periodontists, who are dental specialists focused on the gums and supporting structures of the teeth, most commonly perform this procedure. [3]
The procedure is typically performed in a single office visit. Most cases today use a dental laser, though some situations still call for a traditional scalpel. Both approaches aim to achieve the same result: a gum line that looks natural and supports good oral health.
When Is Gum Contouring Recommended?
Gum contouring is recommended when excess, uneven, or receded gum tissue affects your appearance or prevents proper dental treatment.
Cosmetic Reasons
The most common cosmetic reason for gum contouring is a "gummy smile." This is when a large amount of gum tissue shows above the upper teeth during a normal smile. A gummy smile is generally defined as showing more than 3 to 4 millimeters of gum tissue when smiling. [6] The teeth may look short or stubby even though they are a normal size underneath the tissue.
An uneven gum line is another common cosmetic concern. Some teeth may have higher gum margins than others, which makes the smile appear asymmetrical. Gum contouring can even out these differences so the teeth appear more uniform. Research supports the importance of gum symmetry in smile aesthetics. A prospective clinical study of 12 patients who underwent crown lengthening in the upper front teeth found that gum levels remained stable at the six-month follow-up, confirming that the cosmetic results can be predictable and lasting when proper technique is used. [7]
Genetics, certain medications (such as some anti-seizure drugs, calcium channel blockers, and immunosuppressants), and some health conditions can all influence gum tissue volume and shape. [3] In many cases, excess gum tissue is simply a natural variation that a patient wants to change for aesthetic reasons.
Functional and Medical Reasons
Gum contouring is sometimes medically necessary. A common functional indication is crown lengthening. This is when a dentist needs to expose more of the tooth surface to place a dental crown, bridge, or large filling. Without enough exposed tooth structure, the restoration may not fit properly or may fail over time. Crown lengthening restores what is known as adequate biologic width, the minimum distance between the edge of a restoration and the underlying bone that the body needs for healthy tissue attachment. [6]
Periodontal disease (gum disease) can also change the shape of the gum tissue. According to the American Academy of Periodontology, gum disease affects the tissues that support the teeth and can cause swelling, irregular tissue growth, or pocket formation around the teeth. [3] After treating the underlying infection, gum contouring can reshape damaged tissue to reduce pockets and restore a healthier gum architecture.
In some restorative cases, the margin of a tooth fracture or area of decay sits below the gum line. A periodontist may need to recontour the gum tissue to access the damage and allow for a proper seal between the tooth and the restoration.
What to Expect: Before, During, and After the Procedure
Gum contouring is typically completed in a single office visit lasting 30 minutes to two hours, depending on how many teeth are involved.
Before the Procedure
Your dentist or periodontist will start with a thorough examination of your gums, teeth, and jawbone. This often includes dental X-rays to check the bone levels beneath the gum tissue. If bone reshaping (osseous surgery) is also needed, the treatment plan will be different from a soft-tissue-only procedure.
Your provider will draw or mark the new gum line on your tissue so you can see and approve the planned changes before any cutting begins. This is a good time to ask questions about how much tissue will be removed and what the expected result will look like.
You will receive instructions about eating, drinking, and any medications to avoid before the appointment. If you take blood thinners, your provider may coordinate with your physician. A professional dental cleaning is usually recommended before the procedure to reduce bacteria in the mouth. The American Dental Association emphasizes the importance of maintaining good oral health before any dental surgery, as a clean starting point helps support predictable healing. [4]
During the Procedure
Gum contouring is performed under local anesthesia (numbing medication injected into the gum tissue). You will be awake but should not feel pain. For patients with dental anxiety, sedation options such as nitrous oxide (laughing gas) or oral sedation may be available.
With a laser procedure, the provider uses a concentrated beam of light energy to remove and reshape the gum tissue. The laser seals blood vessels as it works, which typically means less bleeding and less swelling compared to a scalpel. The laser also sterilizes the tissue as it cuts, which may lower the risk of infection. Research supports that diode lasers used for soft tissue procedures have received FDA 510(k) clearance for oral soft tissue surgery, though it is important to note that clearance means the device is substantially equivalent to a previously marketed device, not that it has undergone the more rigorous premarket approval process. [5]
With a scalpel procedure, the provider uses a surgical blade to trim and reshape the tissue. Sutures (stitches) are usually needed to hold the tissue in its new position. Scalpel procedures may be preferred when a larger area of tissue needs to be removed or when bone recontouring is part of the plan.
If bone reshaping is required, the provider will fold back the gum tissue, remove or reshape a small amount of bone around the tooth, then reposition the tissue. This is a more involved version of the procedure called crown lengthening with osseous surgery.
Immediately After the Procedure
Once the numbness wears off, you will likely feel some tenderness and soreness around the treated area. Your provider may prescribe pain medication or recommend over-the-counter options such as ibuprofen or acetaminophen.
You will receive specific instructions about what to eat, how to brush, and what activities to avoid. Soft foods are typically recommended for the first few days. Your provider may also give you a special mouth rinse (often chlorhexidine gluconate) to keep the area clean while it heals.
Swelling is normal and usually peaks within the first 24 to 48 hours. Applying a cold compress to the outside of your cheek in 15-minute intervals can help reduce swelling on the first day.
Risks and Potential Complications
Like any surgical procedure, gum contouring carries some risks. The most common include post-operative bleeding, swelling, and infection. These are typically mild and manageable with proper aftercare.
Less common risks include damage to the tooth root if too much tissue or bone is removed, tooth sensitivity due to newly exposed root surfaces, and relapse or uneven healing that may require a follow-up procedure. In rare cases, excessive tissue removal can lead to gum recession that exposes the tooth root permanently, which may increase sensitivity and the risk of root decay. [6]
Patients should discuss their full medical history with their provider before the procedure. Conditions such as uncontrolled diabetes, bleeding disorders, or immune suppression may increase the risk of complications. Smoking also slows healing and increases the risk of infection. Your provider may recommend quitting smoking before and after the procedure to improve outcomes. [3]
Recovery Timeline and Aftercare
Most patients return to normal activities within a few days, though full tissue healing takes several weeks.
What to Expect at Each Stage
Day 1 to 3: Expect tenderness, swelling, and some minor bleeding. Stick to soft, cool foods like yogurt, smoothies, scrambled eggs, and mashed potatoes. Avoid spicy, crunchy, or acidic foods. Do not use a straw, as the suction can disturb healing tissue. Gently rinse with warm salt water or the prescribed mouth rinse after meals.
Week 1: Swelling and tenderness decrease noticeably. You can typically return to work or school within one to three days for laser procedures, and within a few days for scalpel procedures. You may be able to start eating slightly firmer foods, but continue to chew away from the surgical area. Follow your provider's instructions about when to resume brushing and flossing near the treated gums.
Week 2 to 4: The gum tissue continues to firm up and mature. The gum line will start to take its final shape, though minor refinement can continue for several weeks. By the end of week two, most patients feel comfortable eating a normal diet. A follow-up appointment is usually scheduled during this window so your provider can check healing progress.
Month 1 to 3: The tissue is typically fully healed and has settled into its permanent position. The final aesthetic result is usually visible by this point. In cases involving bone reshaping, complete healing may take closer to three months. A six-month prospective study of crown lengthening in the upper front teeth found that gum tissue levels stabilized and remained consistent after healing, supporting the long-term predictability of the results. [7]
Normal Healing vs. When to Call the Office
Mild soreness, swelling, and slight bleeding during the first two to three days are normal. Pink or slightly reddish saliva is expected. The tissue may look white or yellowish in the first week as a protective layer forms over the healing area. This is a normal part of the process.
Contact your provider if you experience heavy bleeding that does not stop with gentle pressure after 20 minutes. Increasing pain after the first three days, rather than decreasing pain, is another reason to call. Fever, pus, or a foul taste in your mouth may indicate infection and should be evaluated promptly.
Also call if you notice that the gum tissue appears to be pulling away from the teeth or if you feel that your bite has changed. These signs are uncommon but should be assessed by your provider.
Gum Contouring Cost and Insurance
Gum contouring typically costs between $300 and $3,000, though the final price depends on several factors. Costs vary by location, provider, and case complexity.
A minor cosmetic reshaping of one or two teeth may fall toward the lower end of that range. Reshaping the gum line across multiple teeth, or procedures that include bone recontouring, fall toward the higher end. The type of technology used (laser versus scalpel) can also affect the fee, as laser equipment involves higher overhead costs for the practice.
Dental insurance typically does not cover gum contouring when it is performed for purely cosmetic reasons. However, if the procedure is medically necessary, such as crown lengthening to support a dental restoration or tissue recontouring after periodontal disease treatment, insurance may cover a portion of the cost. [3] Check with your insurance provider before the procedure to understand your specific coverage.
Many dental and periodontal offices offer payment plans or work with third-party financing companies. Asking about these options during your consultation can help you plan for out-of-pocket expenses. Some offices also provide a detailed pre-treatment estimate that you can submit to your insurer for a coverage determination before the procedure.
Who Should Perform Your Gum Contouring?
A periodontist is the most qualified specialist for gum contouring, especially for complex cases involving bone or extensive tissue changes. [3]
Periodontists complete an additional three years of training beyond dental school, focusing on the gums, bone, and other structures that support the teeth. This advanced training covers both surgical and non-surgical management of gum tissue. According to the American Academy of Periodontology, periodontists are specialists in the prevention, diagnosis, and treatment of periodontal disease, as well as the placement of dental implants and related procedures. [3]
General dentists can perform minor cosmetic gum contouring in some cases, particularly straightforward laser reshaping on one or two teeth. However, cases that involve uneven bone levels, significant tissue removal, or areas near important anatomical structures typically benefit from a periodontist's expertise.
If your case involves crown lengthening before a dental restoration, a periodontist and your restorative dentist will often work together. The periodontist reshapes the tissue and bone, and the restorative dentist later places the crown or filling. This collaboration helps ensure that the final result is both functional and aesthetically pleasing.
