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.

As your dental provider, we're always alert for signs of tooth decay or periodontal (gum) disease, the two leading causes of tooth loss. But we're also watching for less common conditions that could be just as devastating.
Root resorption falls into this latter category: it occurs when a tooth's root structure begins to break down and dissolve (or resorb). It's a normal process in primary ("baby") teeth to allow them to loosen and give way when permanent teeth are ready to erupt.
It's not normal, though, for permanent teeth. Something internally or—more commonly—externally causes the root structure to break down. External resorption usually occurs at the neck-like or cervical area of a tooth around the gum line. Known as external cervical resorption (ECR), it can first appear as small, pinkish spots on the enamel. These spots contain abnormal cells that cause the actual damage to the root.
We don't fully understand how root resorption occurs, but we have identified certain factors that favor its development. For example, it may develop if a person has experienced too much force against the teeth during orthodontic treatment. Injury to the periodontal ligaments, teeth-grinding habits or some dental procedures like internal bleaching may also contribute to later root resorption.
Early diagnosis is a major part of effective treatment for root resorption. Because it's usually painless and easily overlooked, resorption is often too difficult to detect in its early stages without x-rays—a good reason for regular dental exams. Beginning spots or lesions are usually small enough to surgically remove the tissue cells causing the damage and then filled with a tooth-colored filling material. If it has advanced further, we may also need to perform a root canal treatment.
At some point, the damage from root resorption can be too great, in which case it might be best to remove the tooth and replace it with a dental implant or similar restoration. That's why catching root resorption early through regular dental exams can give you the edge for saving your tooth.

Untreated tooth decay can destroy your teeth; prompt action as soon as its diagnosed will help prevent that undesirable outcome. And even if decay has advanced into the tooth's pulp and root canals, there's still a good chance we can stop it with a root canal treatment. Using this procedure, we can clean out the infection and refill the tooth's interior space with a special filling to protect it from further infection.
Although root canal treatments have gained an unwarranted reputation for pain, they rarely cause even the mildest discomfort. More importantly, they work, which is why they're the go-to treatment dentists use for advanced decay.
But sometimes a unique dental situation might make performing a root canal extremely difficult—possibly even doing more harm than good. For example, trying to access the interior of a tooth with a crown restoration might require removing the crown, which could further weaken or damage the tooth. In other cases, the root canals might have become calcified due to trauma or aging and become too narrow to access.
Even so, we may still be able to save a tooth through a minor surgical procedure called an apicoectomy. Rather than access the diseased area through the tooth crown as with a root canal treatment, an apicoectomy makes access to the infected tissue at the root end.
An apicoectomy also differs from a root canal treatment in that we'll need to surgically go through the gum tissue. After numbing the area with a local anesthetic, we'll make a small incision through the gums at the level of the infection. After removing any infected tissue, we would then fill the space with a small filling to prevent re-infection. We then close the incised gum tissues with sutures and allow them to heal.
With the help of fiber optic lighting and surgical microscopes, endodontists (specialists in interior tooth problems) can perform an apicoectomy quickly and with very little trauma at the surgical sight. If you undergo an apicoectomy, you should be back to normal activity in a day or two at the most. And like its sister procedure the root canal, an apicoectomy could help preserve your teeth for many years to come.
