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.
Your mouth is a lot like the Wild West — home to millions of bacteria and other microbes, some of which are definitely not “the good guys.” But your teeth are well-protected from these hostile forces and their acidic waste products: with enamel shielding the visible part of your tooth, your gums protect the parts you can’t see.
As effective as they are, though, your gums aren’t invincible: their greatest threat is periodontal (gum) disease. This bacterial infection arises from plaque, a thin film of bacteria and food particles accumulating on teeth due to inadequate brushing and flossing.
The infected tissues soon become inflamed (red and swollen), a natural defensive response from the immune system. The longer they’re inflamed, however, the more likely they’ll begin detaching from the teeth. The gums may eventually shrink back or recede from the teeth, often causing them to appear “longer” because more of the tooth is now exposed to view.
Gum recession doesn’t bode well for your teeth’s survival: the exposed tooth and underlying bone can become even more susceptible to infection and damage. In the end, you could lose your tooth and portions of the supporting bone.
Treatment depends on the severity of the gum recession. In mild to moderate cases, we may only need to perform the standard gum disease treatment of removing plaque and calculus from all gum and tooth surfaces (including below the gum line) with special instruments. This helps reduce the infection and allow the gums to heal and re-establish attachment with the tooth. In more advanced cases, though, the recession may be so extensive we’ll need to graft donor tissue to the area using one of a variety of surgical techniques.
Although the right treatment plan can help restore your gum health, there’s another approach that’s even better — preventing gum disease in the first place. You can reduce your disease risk by practicing daily brushing and flossing and visiting your dentist regularly or when you see symptoms like gum swelling or bleeding. Taking care of your gums won’t just save your smile — it might also save your teeth.
