If all goes normally, we have most of our permanent teeth as we enter puberty. Except, though, when it doesn't—sometimes incoming permanent teeth don't fully erupt, often because there's not enough room for them on the jaw. This can leave all or part of a tooth still up inside the gum and bones.
This condition is known as impaction, and it can cause problems with a person's bite and their smile. This is especially true of the upper canines, those pointed teeth located just under the eyes. Without them present, a person's smile can look oddly different. Moreover, it can worsen their bite and increase the risk of trauma and disease for nearby teeth.
Fortunately, there may be a way to coax impacted canines into erupting into their proper position on the jaw. It will involve, though, some minor surgery and orthodontic intervention to accomplish that feat.
First, though, a patient with missing canines should undergo a thorough orthodontic evaluation. This exam will reveal not only what may be going on with the missing teeth, but how the whole bite has been affected. Knowing the big picture will help direct the next treatment steps.
After pinpointing the impacted teeth's exact position (usually through x-rays or cone beam CT scanning), we then decide whether it's feasible to attempt to expose the teeth. Sometimes, a tooth's position is so out of place that it may be best to remove it and consider a dental implant or other restorative measures.
If it is in a workable position, then the impacted teeth would be exposed surgically (usually by an oral surgeon or periodontist). The surgeon would then bond a small bracket to the exposed tooth and then attach a small chain.
After suturing the incised gum tissues back in place, the chain extending outward from the gums would then be looped over orthodontic hardware attached to other teeth. This will place downward pressure on the upper canine tooth, and over several months prod it to fully erupt.
This may sound like an elaborate procedure, but it's fairly routine and predictable. As a result, a patient can finally get the full benefit of all their teeth, enhance their dental health and transform their 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.
As Spring turns to Summer, millions of students will depart high school in the time-honored rite of passage called graduation. At the same time, quite a few of these graduates will be experiencing another maturity milestone: the eruption (coming in) of their last permanent teeth.
Typically, these are the back third molars, better known as “wisdom teeth,” emerging on either end of both the top and bottom jaws sometime between the ages of 18 and 24. Their arrival heralds the end of a long development process that began in infancy.
But this auspicious event can give rise to dental problems. Because they’re the last to come in, wisdom teeth often erupt in an environment crowded by earlier teeth. Depending on jaw size and other factors, there may not be enough room for a normal eruption.
Wisdom teeth can thus erupt out of position, creating a poor bite (malocclusion). Or they might not erupt at all—becoming stuck fully or partially within the gums and bone, a condition known as impaction. Impacted teeth can also cause problems for the adjacent teeth, damaging the roots of the second molars or disrupting the surrounding gum tissue, making them more susceptible to periodontal (gum) disease.
Because of these and other issues, impacted wisdom teeth are among the most common type of teeth removed: an estimated 10 million each year. And many of these are removed before they show signs of disease or complications as a preemptive strike against developing dental problems.
Although unnecessary surgery should always be avoided, according to some research, there’s a one in three chance that erupting wisdom teeth that are not showing signs of trouble will eventually become problematic. And the earlier they’re removed, the lower the risk of post-extraction complications.
Wisdom teeth should always be evaluated on a case by case basis. Those with obvious signs of disease or complications do require prompt treatment, including possible extraction. Others that are asymptomatic can be monitored over time: If they’re tending to become problematic, we can adjust the treatment plan accordingly. Our goal is to ensure these particular teeth signaling the end of childhood won’t detract from dental health in adulthood, so a measured approach seems to be the best and safest one.

As permanent teeth gradually replace primary (“baby”) teeth, most will come in by early adolescence. But the back third molars—the wisdom teeth—are often the last to the party, usually erupting between ages 18 and 24, and the source of possible problems.
This is because the wisdom teeth often erupt on an already crowded jaw populated by other teeth. As a result, they can be impacted, meaning they may erupt partially or not at all and remain largely below the gum surface.
An impacted tooth can impinge on its neighboring teeth and damage their roots or disrupt their protective gum attachment, all of which makes them more susceptible to tooth decay or periodontal (gum) disease. Impacted teeth can also foster the formation of infected cysts that create areas of bone loss or painful infections in the gums of other teeth.
Even when symptoms like these aren’t present, many dentists recommend removing the wisdom teeth as a preemptive measure against future problems or disease. This often requires a surgical extraction: in fact, wisdom teeth removal is the most common oral surgical procedure.
But now there’s a growing consensus among dentists that removing or not removing wisdom teeth should depend on an individual’s unique circumstances. Patients who are having adverse oral health effects from impacted wisdom teeth should consider removing them, especially if they’ve already encountered dental disease. But the extraction decision isn’t as easy for patients with no current signs of either impaction or disease. That doesn’t mean their situation won’t change in the future.
One way to manage all these potentialities is a strategy called active surveillance. With this approach, patient and dentist keep a close eye on wisdom teeth development and possible signs of impaction or disease. Most dentists recommend carefully examining the wisdom teeth (including diagnostic x-rays and other imaging) every 24 months.
Following this strategy doesn’t mean the patient won’t eventually have their wisdom teeth removed, but not until there are clearer signs of trouble. But whatever the outcome might be, dealing properly with wisdom teeth is a high priority for preventing future oral health problems.

The reason for extracting a tooth may be all too obvious — the tooth is too decayed or damaged to attempt saving. The reason for extracting a wisdom tooth, on the other hand, may not be so apparent: from the perspective of pain or reduced function, you may not notice a thing. Our recommendation to remove a wisdom tooth is based primarily on what may be occurring out of view below the gum line and its potential threat to adjacent teeth.
Teeth grow and develop below the gum line in the jaw, and then push their way through the gums as they appear in the mouth (eruption). After a normal eruption, the enamel-covered crown is visible above the gum line; the remaining tooth root (about two-thirds of the tooth’s length) resides below the gum line. Because wisdom teeth, or third molars, erupt rather late between ages 17 and 25, they may lack the room to erupt properly due to crowding from other teeth that have already erupted. This can cause the wisdom tooth not to erupt fully through the gums, leaving the crown trapped below the gum line, a condition known as impaction. For the tooth, impaction increases the chances of infection, cyst formation and gum disease around it.
An impacted wisdom tooth can also cause problems for the adjacent teeth as well. The impacted tooth may begin to press against the roots of other teeth; the resulting pressure can damage the other roots, increasing the risk for disease or future tooth loss. A person may not even know they have this problem since there’s often little to no noticeable pain or symptoms.
It may seem counterintuitive, but the best time to remove a wisdom tooth is when it’s not causing immediate problems. There will be, however, signs found during examination (particularly x-rays or CT scan) that future problems are in the making. By extracting an impacted wisdom tooth at the appropriate time, we can avoid more serious problems in the future and improve oral health.
