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.

Applying braces or clear aligners to move misaligned teeth is only part of an orthodontist's overall mission to eliminate poor bites (malocclusions). Sometimes a malocclusion isn't caused by the teeth at all—the size of the jaw is the problem!
One type in particular, a cross-bite, often happens because the upper jaw has developed too narrowly. As a result, many of the upper teeth fit inside the lower, the opposite of normal. But a tool called a palatal expander can alleviate the problem if it's applied at an early enough age.
The device works because the upper jawbone initially forms as two halves that fit together along a center line in the roof of the mouth (the palate) running from the back of the mouth to the front. These two bone halves remain separate during childhood to facilitate jaw growth, but eventually fuse around puberty.
Consisting of two sets of wire arms joined together by a hinge mechanism in the middle, the expander device is positioned up against the palate. The orthodontist extends each arm to press against the inside of the back teeth, then adds more outward pressure by turning the mechanism in the middle with a small key. During wear, the patient or caregiver will turn the mechanism in the same way to keep up the pressure on the two sides of the jaw.
This continual pressure keeps the two bones moving away from each other and maintaining a center gap between them. In response, more bone forms on the two halves to fill the gap. In time, the newly formed bone should widen the jaw enough to correct any developing malocclusion.
Timing is everything with a palatal expander—if not used before the jaw bones fuse, the patient will need a surgical procedure to separate the bones to pursue treatment. To catch the problem early enough, children should have an orthodontic evaluation on or before they turn six. An orthodontist may be able to identify this or other emerging bite problems and intervene before it becomes worse. Taking this approach can help save you and your child more expensive orthodontic treatment down the road.
If you would like more information on correcting poor bites, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Palatal Expanders: Orthodontics is more than just Moving Teeth.”
A toothache means a tooth has a problem, right? Most of the time, yes: the pain comes from a decayed or fractured tooth, or possibly a gum infection causing tooth sensitivity.
Sometimes, though, the pain doesn't originate with your teeth and gums. They're fine and healthy—it's something outside of your tooth causing the pain. We call this referred pain—one part of your body is sending or referring pain to another part, in this instance around your mouth.
There are various conditions that can create referred pain in the mouth, and various ways to treat them. That's why you should first find out the cause, which will indicate what treatment course to take.
Here are a few common non-dental causes for tooth pain.
Trigeminal Neuralgia. The trigeminal nerves situated on either side of the face have three large branches that extend throughout the face; the branch to the jaw allows you to feel sensation as you chew. When one of the nerve branches becomes inflamed, usually from a blood vessel or muscle spasm pressing on it, it can refer the pain to the jaw and seem like a toothache.
Temporomandibular Joint Disorder (TMD). These two joints that connect the lower jaw to the skull can sometimes become dysfunctional for a variety of reasons. This can set up a cycle of spasms and pain that can radiate throughout the jaw and its associated muscles. The pain can mimic a toothache, when it actually originates in the jaw joints.
Teeth Grinding. This is an unconscious habit, often occurring at night, in which people clench or grind their teeth together. Although quite common in children who tend to grow out of it, teeth grinding can continue into adulthood. The abnormally high biting forces from this habit can cause chipped, broken or loosened teeth. But it can also cause jaw pain, headaches and tenderness in the mouth that might feel like a toothache.
These and other conditions unrelated to dental disease can seem like a tooth problem, when they're actually something else. By understanding exactly why you're feeling pain, we can then focus on the true problem to bring relief to your life.
