Every year dentists place over 5 million dental implants for lost teeth, often removing the problem tooth and installing the implant at the same time. But getting a “tooth in a day” depends on a number of health factors, especially whether or not there’s adequate bone available for the implant. Otherwise, the implant’s placement accuracy and success could be compromised.
Bone loss can be a similar problem when a tooth has been missing for a long period of time. If this describes your situation, you may have already lost substantial bone in your jaw. To understand why, we need to know a little about bone’s growth cycle.
When bone cells reach the end of their useful life, they’re absorbed into the body by a process called resorption. New cells then form to take the older cells’ place in a continuous cycle that keeps the bone healthy and strong. Forces generated when we chew travel through the teeth to the bone and help stimulate this growth. But when a tooth is missing, the bone doesn’t receive this stimulus. As a result, the bone may not replace itself at a healthy rate and diminish over time.
In extreme cases, we may need to consider some other dental restoration other than an implant. But if the bone loss isn’t too severe, we may be able to help increase it through bone grafting. We insert safe bone grafting material prepared in a lab directly into the jaw through a minor surgical procedure. The graft then acts like a scaffold for bone cells to form and grow upon. In a few months enough new bone may have formed to support an implant.
Bone grafting can also be used if you’re having a tooth removed to preserve the bone even if you’re not yet ready to obtain an implant. By placing a bone graft immediately after extraction, it’s possible to retain the bone for up to ten years—enough time to decide on your options for permanent restoration.
Whatever your situation, it’s important that you visit us as soon as possible for a complete examination. Afterward we can assess your options and hopefully come up with a treatment strategy that will eventually include smile-transforming dental implants.
The March 27th game started off pretty well for NBA star Kevin Love. His team, the Cleveland Cavaliers, were coming off a 5-game winning streak as they faced the Miami Heat that night. Less than two minutes into the contest, Love charged in for a shot on Heat center Jordan Mickey—but instead of a basket, he got an elbow in the face that sent him to the floor (and out of the game) with an injury to his mouth.
In pictures from the aftermath, Love’s front tooth seemed clearly out of position. According to the Cavs’ official statement, “Love suffered a front tooth subluxation.” But what exactly does that mean, and how serious is his injury?
The dental term “subluxation” refers to one specific type of luxation injury—a situation where a tooth has become loosened or displaced from its proper location. A subluxation is an injury to tooth-supporting structures such as the periodontal ligament: a stretchy network of fibrous tissue that keeps the tooth in its socket. The affected tooth becomes abnormally loose, but as long as the nerves inside the tooth and the underlying bone have not been damaged, it generally has a favorable prognosis.
Treatment of a subluxation injury may involve correcting the tooth’s position immediately and/or stabilizing the tooth—often by temporarily splinting (joining) it to adjacent teeth—and maintaining a soft diet for a few weeks. This gives the injured tissues a chance to heal and helps the ligament regain proper attachment to the tooth. The condition of tooth’s pulp (soft inner tissue) must also be closely monitored; if it becomes infected, root canal treatment may be needed to preserve the tooth.
So while Kevin Love’s dental dilemma might have looked scary in the pictures, with proper care he has a good chance of keeping the tooth. Significantly, Love acknowledged on Twitter that the damage “…could have been so much worse if I wasn’t protected with [a] mouthguard.”
Love’s injury reminds us that whether they’re played at a big arena, a high school gym or an outdoor court, sports like basketball (as well as baseball, football and many others) have a high potential for facial injuries. That’s why all players should wear a mouthguard whenever they’re in the game. Custom-made mouthguards, available for a reasonable cost at the dental office, are the most comfortable to wear, and offer protection that’s superior to the kind available at big-box retailers.
If you have questions about dental injuries or custom-made mouthguards, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “The Field-Side Guide to Dental Injuries” and “Athletic Mouthguards.”
Gum recession — when the gum tissue covering teeth wears away — is a serious matter. If the roots become exposed you'll not only have increased sensitivity and possible discomfort, your teeth can become more susceptible to decay.
There are a number of reasons for gum recession, including overaggressive brushing and flossing, poor fitting appliances like dentures or braces, or genetics (inheriting a thin gum tissue type or poor tooth position). Perhaps the most common reason, though, is periodontal (gum) disease. Caused by bacterial plaque, a thin film of food particles that builds up on tooth surfaces, the disease weakens the gum tissues around teeth, causing them ultimately to detach and “roll up” toward the roots.
Treating the gum infection by removing the built-up plaque and calculus (hardened plaque deposits) will help stop recession or even reverse it. Â As we remove plaque the infection subsides and the gums cease to be inflamed. If they haven't receded too far they may re-grow and renew their attachment to the teeth.
In other cases, though, the recession may have progressed too far and too rapidly toward root exposure. Gums in this condition may require tissue grafts to the recessed area to create or regenerate new tissue.
Most grafting techniques fall into one of two categories. The first is known as free gingival grafting where a thin layer of skin is removed or "freed" from the roof of the patient's mouth (the palate), shaped and then stitched to the recession site.
The second category is called connective tissue grafting, most often used to cover exposed roots. In this case the donor material is transplanted from the donor site to the recipient site, but the recipient site's tissue covers the donor connective tissue graft as it still maintains a physical attachment to the original location. The recipient site can thus maintain a blood supply, which can result in quicker, more comfortable healing than with free gingival grafting.
Connective tissue grafting does, however, require sophisticated microsurgical techniques, along with the surgeon's in-depth skill and art, to prepare both the donor and recipient sites. Allografts (donor skin from another person) may also be used as a donor tissue and placed beneath the recipient site tissue thereby avoiding a second surgical site.
Gum tissue grafting can be an intense undertaking, but the results can be astounding. Not only will restoring recessed gum tissues give your teeth a new lease on life, it will revitalize your smile.
