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.
Braces are a common experience among teens and pre-teens. And although the treatment can be a major financial undertaking, more and more families pursue it to help their child attain a straighter, more attractive smile.
But orthodontics isn’t first and foremost a cosmetic treatment. Although an improved appearance is a benefit, the main reason for treatment is therapeutic—it can improve your child’s current and future dental health.
The teeth’s relationship to the jaws and gums makes moving them possible. Rather than simply being fixed within their jawbone socket, teeth are actually held in place by a strong, elastic tissue called the periodontal ligament. The ligament lies between the teeth and jawbone and attaches to both with tiny extending fibers. This attachment secures the teeth in place.
But the ligament also has a dynamic quality—it can reshape itself when necessary and allow teeth to move gradually into new positions. This is most necessary during the early years of mouth and jaw development, but it can also occur throughout life. Orthodontics takes advantage of this mechanism by applying precise pressure to the teeth in the direction of desired movement. The periodontal ligament does the rest by reshaping and allowing the teeth to move in response to this pressure.
The result is straighter teeth and a more normal bite. With the teeth now where they should be, it’s also easier to clean them of disease-causing dental plaque, whereas misaligned teeth are more prone to plaque accumulation that can be difficult to remove. And because the whole mouth including teeth are involved when we talk, teeth positioned in a more normal bite will improve speech.
Orthodontics is a long-term process, often encompassing more than the actual time wearing braces. Both orthodontists and pediatric dentists recommend a bite evaluation by an orthodontist around the age of 6. If it does appear an abnormal bite is forming, it may be possible to intervene and stop or at least slow the development. This could have a more positive impact on any future treatment.
Braces and other treatments can make a difference in your child’s self-image and social relationships. But the main beneficiary will be their dental health.

Although periodontal (gum) disease starts with the gums, the teeth may ultimately suffer. An infection can damage the gum attachment and supporting bone to the point that an affected tooth could be lost.
The main cause for gum disease is dental plaque, a bacterial biofilm that accumulates on teeth due to ineffective oral hygiene. But there can be other contributing factors that make you more susceptible to an infection. Smoking tobacco is one of the most harmful as more than half of smokers develop gum disease at some point in their life. If you’re a heavy smoker, you have double the risk of gum disease than a non-smoker.
There are several reasons why smoking increases the risk of gum disease. For one, smoking reduces the body’s production of antibodies. This diminishes the body’s ability to fight oral infections and aid healing. As a smoker, your body can’t respond adequately enough to the rapid spread of a gum infection.
Another reason for the increased risk with smoking are the chemicals in tobacco that damage the connectivity of gum tissues to teeth that keep them anchored in place. The heavier the smoking habit, the worse this particular damage is to the gums. This can accelerate the disease and make it more likely you’ll lose affected teeth.
Smoking can also interfere with getting a prompt diagnosis of gum disease because the nicotine in tobacco reduces the blood supply to the gums. Usually a person with an infection may first notice their gums are reddened or swollen, and bleed easily. Smoking, however, can give a false impression of health because it prevents the infected gum tissues from becoming swollen and are less likely to bleed. As a result, you may learn you have the disease much later rather than sooner, allowing the infection to inflict more damage.
There are ways to reduce your disease risk if you smoke. The top way: Kick the smoking habit. With time, the effects of smoking on your mouth and body will diminish, and you’ll be better able to fight infection.
You should also practice daily brushing and flossing to keep plaque at bay, followed by regular dental cleanings to remove hard to reach plaque and calculus (tartar) deposits. You should also see your dentist at the first sign of trouble with your gums.
