Bite problems aren't limited to teeth simply out of position. The problem could be some teeth aren't there—visibly, that is. They still exist below the gums and bone, but they've been crowded out and blocked from erupting. We call this condition impaction.
Any tooth can become impacted and affect the bite, but a person's smile suffers more if it involves visible front teeth. This is especially so if the teeth in question are upper canines or "eye teeth"—the smile doesn't look normal without these pointed teeth on either side of the central and lateral incisors.
Impacted teeth can also contribute to more than a cosmetic problem: they're more susceptible to abscesses (pockets of infection) or root damage both to themselves or neighboring teeth. To minimize these potential health issues, we'll often remove impacted teeth surgically (as is often done with wisdom teeth).
But because of their important role in not only appearance but also bite function, we may first try to assist impacted canines to fully erupt before considering extraction. It takes a bit of orthodontic "magic," but it can be done.
Before we can make that decision, though, we want to precisely locate the impacted teeth's positions and how it may affect other teeth. This initial evaluation, often with advanced diagnostics like CT scanning or digital x-rays, helps us determine if the impacted teeth are in a workable position to save. If they're not, we may then need to consider removing them and ultimately replacing them with a dental implant or similar restoration.
But if their position is workable and there are no other impediments, we can proceed with helping them erupt. To do this we'll have to first expose them by creating a small opening in the gums through minor surgery. We then bond a small bracket to the tooth, to which we'll attach a small chain that we then attach to orthodontic braces. This enables us to exert continuous pressure on the tooth.
Over time, the pressure coaxes the tooth to erupt. We may still need to apply other forms of orthodontics and cosmetic procedures, but using this procedure to rescue impacted canines can produce a healthier and more attractive smile.

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.
Chicken pox is a common viral infection that usually occurs during childhood. Although the disease symptoms only last a short time, the virus that caused it may remain, lying dormant for years within the body's nervous system. Decades later it may reappear with a vengeance in a form known as herpes zoster, what most people know as shingles.
A shingles outbreak can be quite painful and uncomfortable—and it's also not a condition to take lightly. Occurring mainly in people over fifty, it often begins with an itching or burning sensation in the skin. This is often followed by a red rash breaking out in a belt-like pattern over various parts of the body, which may later develop into crusty sores. Symptoms may vary from person to person, but people commonly experience severe pain, fever and fatigue.
Besides the general discomfort it creates, shingles can also pose major health problems for certain people. Individuals with other health issues like pregnancy, cancer or a compromised immune system may experience serious complications related to a shingles outbreak.
In its early stages, shingles is contagious, spreading through direct contact with shingles sores or lesions or through breathing in the secretions from an infected person. This characteristic of shingles could affect your dental care: because the virus could potentially pass to staff and other patients, dentists usually postpone cleanings or other dental treatments for patients with shingles, particularly if they have a facial rash.
If you're diagnosed with shingles, most physicians recommend you begin antiviral treatment as soon as possible. You should also let your dentist know if you have shingles, which may put off any scheduled treatments until your doctor determines you're no longer contagious.
There's one other thing you can do, especially if you're over 60: obtain a shingles vaccine, available from most physicians or clinics. The vaccine has proven effective in preventing the disease, and could help you avoid this most unpleasant health experience.
