A crown — a life-like “cap” made of dental porcelain that permanently covers an existing tooth — is an effective way to restore a still-viable decayed or broken tooth’s appearance. Properly fitting the crown over the tooth requires some healthy tooth structure above the gum line.
But what if the tooth has broken down to the gum line? In this case, we would need to perform a common procedure known as crown lengthening to expose more of the tooth.
Crown lengthening is a minor surgical procedure performed with local anesthesia to numb the tooth, surrounding gum tissues and supporting bone. We first make tiny incisions inside the gum-line on both the cheek and tongue side of the tooth to expose the bone, and then carefully remove a small amount of bone from either side of the tooth; this will expose or “lengthen” the tooth. Once finished, we suture the gum tissue back into place with self-dissolving sutures against the bone and tooth.
Most procedures take only sixty to ninety minutes, and the mild discomfort afterward is usually managed with pain relievers like ibuprofen. While the gum tissues may appear to be healed after a week, we typically wait six to eight weeks to perform the final crown restoration to give the tissues time to fully mature.
Crown lengthening may not work in all situations, especially with a severely fractured tooth. In these cases, we may need to evaluate the long-term viability of the tooth and consider other restorative options. Depending on your bite, it may also be necessary to treat with orthodontics first: not only will the tooth move into a better position, but the treatment may move both the gum and bone down with the tooth. Subsequent crown lengthening will then only affect the intended tooth and not adjacent ones, resulting in a more even smile.
The first step is for us to decide after a thorough examination if you would benefit from crown lengthening. If so, this minor surgical procedure could pave the way for better mouth function and a more attractive smile.
While tooth decay is a potential problem at any age, the risk increases as you grow older. Not only are senior adults more susceptible, decay is often more difficult to treat. That’s because cavities can occur at or below the gum line, often due to gum recession.
If that’s the case, we won’t be able to fill the cavity in the usual way because the gum tissue is in the way. To make it possible to treat, we may need to perform a minor surgical procedure known as crown lengthening.
As the name implies, the procedure helps expose more of the crown, the tooth’s visible part, from the surrounding gum tissue. In basic terms, we’re repositioning the gum tissue away from the biting surface of a tooth to make room for a filling. It’s also useful for improving a tooth’s appearance by making it look longer, or creating room for a crown or other dental restoration.
After applying a local anesthesia, the dentist (or periodontist, a specialist in the gums) creates a tiny flap of gum tissue with a series of incisions. This allows the dentist to move the affected gums out of the way to access the underlying bone. The dentist then reshapes the bone to adequately support the gum tissue when it’s finally repositioned to expose the crown. In its new and improved position, the dentist sutures the gum tissue in place.
For a few days afterward, the patient will need to restrict their diet to soft foods, avoid strenuous activities and apply an ice pack to help reduce swelling the day of surgery. They will also prescribe a pain reliever and possibly an antibiotic to reduce the chances of infection.
While most people return to normal activities a few days later, you’ll usually have to wait a few weeks for the gums to heal before undergoing any further treatments for the affected teeth. But even with the wait, crown lengthening could make it possible to not only save your tooth but improve your smile as well.

While we often associate tooth decay with cavities forming in a tooth’s visible or biting surfaces, the occurrence of this all too common disease isn’t limited to those areas. Cavities can develop in any part of a tooth exposed to bacteria.
Gum recession, the shrinking back of the gums from the teeth, can cause such exposure in areas normally covered by the gums. Because these areas are usually more vulnerable to infection when exposed, cavities can develop at or right below the gum line. Because of their location it can be difficult to fill them or perform other treatments.
One way to make it less difficult is to perform a crown lengthening procedure. While the term sounds like we’re increasing the size of the tooth, we’re actually surgically altering the gums to access more of the affected tooth surface for treatment. It’s typically performed in a dental office with local anesthesia by a general dentist or a periodontist, a specialist in the gums.
During the procedure, the dentist starts by making small incisions in the gums to create a tissue “flap” that can be lifted out of the way. This exposes the underlying bone, which they then reshape to support the gum tissue once it’s re-situated in its new position. The dentist then sutures the gums back in place. Once the gums heal, the decayed area is ready for treatment.
Crown lengthening is also useful for other situations besides treating cavities. If a tooth has broken off at the gum line, for example, there may not be enough remaining structure to support a crown. Crown lengthening can make more of the underlying tooth available for the crown to “grab” onto. It’s also useful in some cases of “gummy smiles,” in which too much of the gum tissue is visible in proportion to the tooth size.
Because crown lengthening often involves removing some of the bone and is thus irreversible, you should discuss this procedure with your dentist in depth beforehand. It could be, though, this minor procedure might make it easier to preserve your teeth and even make them look more attractive.
A crown is an effective way to save a tooth and restore its form and function. These life-like “caps” that fit over and are permanently attached to teeth have been used for decades with good results.
For this type of restoration to be effective, though, there must be enough of the natural tooth remaining above the gum line for the crown to “grab on to.” This poses a problem if the tooth has broken or decayed too close to the gum tissue.
Fortunately, there is a way to expose more of the remaining tooth for applying a crown. Known as crown lengthening, this surgical procedure is also used for “gummy” smiles, where normal tooth length is obscured by excess gum tissue that makes the teeth appear shorter.
We begin the procedure by first numbing the tooth and gum area with a local anesthetic. We then make tiny incisions inside the gum line on both the tongue and cheek side of the tooth to create a small flap. With this area below the gum line now open to view, we then determine whether we need to remove excess gum tissue or a small amount of bone around the tooth to expose more of the tooth itself. We then position the opened gum tissue against the bone and tooth at the appropriate height to create an aesthetic result.
You shouldn’t experience any discomfort during the procedure, which usually takes about sixty minutes for a single tooth area (which needs to involve at least three teeth for proper blending of the tissues). The pressures and vibrations from equipment, as well as any post-procedure discomfort, are similar to what you would encounter with a tooth filling. After the gum tissue has healed (about six to eight weeks), we are then able to fit and attach a crown onto the extended area.
Crown lengthening a small area may result in an uneven appearance if you’re dealing within the aesthetic zone. One option in this case is to consider undergoing orthodontic treatment first to correct the potential discrepancy that may result from surgery. After orthodontics, we can perform crown lengthening on just the affected tooth and still achieve an even smile.
Crown lengthening is just one of many tools we have to achieve tooth restorations for difficult situations. Using this technique, we can increase your chances of achieving both renewed tooth function and a more beautiful smile.
