Ask any kid and they'll tell you just how valuable "baby" teeth really are—out of the mouth, of course, and under their pillow awaiting a transaction with the Tooth Fairy. But there's more to them than their value on the Fairy Exchange Market—they play a critical role in future dental health.
Primary teeth provide the same kind of dental function as their future replacements. Children weaned from nursing can now eat solid food. They provide contact points for the tongue as a child learns to speak. And they play a role socially, as children with a "toothsome" smile begin to look more like what they will become when they're fully mature.
But primary teeth also serve as guides for the permanent teeth that will follow. As a future tooth develops below the gum line, the primary tooth preserves the space in which it will erupt. Otherwise, the space can be taken over by other teeth. This crowds out the intended tooth, which may erupt out of position or remain impacted below the gum line.
In either case, the situation could create a poor bite (malocclusion) that can be quite costly to correct. But if we can preserve a primary tooth on the verge of premature loss, we may be able to reduce the impact of a developing malocclusion or even prevent it.
We can help primary teeth last for their intended lifespan by preventing tooth decay with daily oral hygiene or clinically-applied sealants and topical fluoride. If they do become infected, it may be worth the effort to preserve them using procedures similar to a root canal treatment.
If a tooth can't be preserved, then we can try to reserve the empty space for the future tooth. One way is a space maintainer, which is a stiff wire loop attached to metal band bonded around an adjacent tooth. This keeps other teeth from drifting into the space until the permanent tooth is ready to erupt, at which time we can remove the appliance.
Your child may be anxious to get another tooth to put under their pillow. But helping that primary tooth go the distance will be more than worth it for their future dental health.

Your child's permanent teeth come in gradually, starting just as they begin losing their primary ("baby") teeth and not ending until late adolescence or early adulthood. That's when the third molars or "wisdom teeth" close out the process.
Because of their late arrival, wisdom teeth have a high potential for dental problems. With a greater chance of crowding or obstruction by other teeth, wisdom teeth often get stuck fully or partially below the gums and bone (impaction) or erupt out of position. In one study, 7 in 10 people between the ages of 20 and 30 will have at least one impacted wisdom tooth at some time in their lives.
It's not surprising then that wisdom teeth are among the most extracted teeth, to the tune of about 10 million per year. Besides those already diseased or causing bite problems, many are removed preemptively in an attempt to avoid future problems.
But wisdom teeth usually require surgical extraction by an oral surgeon, which is much more involved than a simple extraction by a general dentist. Given the potential consequences of surgical extraction, is it really necessary to remove a wisdom tooth not creating immediate problems?
That's not an easy question to answer because it's often difficult to predict a wisdom tooth's developmental track. Early on it can be disease-free and not causing any problems to other teeth. But as some researchers have found, one in three wisdom teeth at this stage will later develop disease or create other issues.
For many dentists, the best approach is to consider extraction on a case by case basis. Those displaying definite signs of problems are prime for removal. But where there are no signs of disease or other issues, the more prudent action may be to keep a watchful eye on their development and decide on extraction at some later date.
More than likely, your dentist will continue to have an ongoing discussion with you about the state of your child's wisdom teeth. While extraction is always an option, wisdom teeth that aren't yet a problem to dental health may be best left alone.
Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.
In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.
Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.
What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.
Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.
A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment.
