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.
The third molars, called “wisdom teeth” because they usually become visible when a person is 17 to 25 — supposedly the time we achieve wisdom, may have adverse effects on adjacent teeth. Most adults have four wisdom teeth, although some people have more; and some, none at all. The wisest thing to do about wisdom teeth may be to have them removed if they are poorly positioned.
What is an impacted wisdom tooth?
If a wisdom tooth is pushing against gums, other soft tissues, or adjacent teeth at an awkward angle, it is referred to as “impacted.” Usually this occurs when there is not have enough room in the jaws for these last molars to fit next to their adjacent teeth. They can disrupt the gum tissue attachment of their neighboring teeth and the surrounding bone leading to periodontal disease and, ultimately, their loss.
In many cases, impacted teeth are painless, and those who have them have no warning of the problem. Thus it is important to have routine dental exams during the time when the third molars are coming in.
When should wisdom teeth be removed?
It is better to remove wisdom teeth early rather than waiting until periodontal (gum) disease has set in. As individuals age, keeping their wisdom teeth may lead to more serious problems. Periodontal defects tend to get worse in the presence of retained third molars. Furthermore, there is a higher incidence of postoperative symptoms in people over 25.
What are the pros and cons?
Removing impacted third molars can have a negative influence on the periodontal tissues of adjacent second molars. A number of techniques, such as scaling, root planing, and bacterial plaque control, can be used to minimize periodontal problems and promote healthy healing.
Surgical removal of wisdom teeth will involve some mild to moderate post-operative discomfort. Use of aspirin or ibuprofen for a few days after surgery will provide pain relief and control most swelling and symptoms. Antibiotics may be prescribed to ensure infection-free healing. It is important to keep the socket area clean by washing and rinsing with saline or antibacterial rinses. Careful surgery will promote good healing with minimal periodontal consequences to adjacent second molar teeth.
To decide whether your wisdom teeth should be removed, you will need an evaluation to assess the clinical health of the wisdom teeth, the neighboring teeth, and other vital structures. X-ray and digital imaging techniques play an important role in determining the exact position of the wisdom teeth in the jaw. A full assessment and consultation will include all the risks, benefits, likely consequences, and alternative treatment options. This will provide you with the wisdom you need to determine what is best for your wisdom teeth.
