Dentists extract millions of teeth each year, mostly because of disease. But sometimes a healthy tooth is removed to gain a more favorable, long-term dental health outcome.
An example of this is extracting teeth for the sake of orthodontic treatment. This is often beneficial when treating bite problems caused by crowding, a condition in which not enough space on the jaw exists to accommodate all of the teeth coming in. When this happens, the limited space can force teeth out of their proper alignment.
Crowding also complicates correcting the bite problem with braces: As with the eruption phase, there's no available room for orthodontic movement. One solution that may arise after a detailed examination is to open up space on the jaw by removing some of the teeth.
Planning this kind of tooth extrication requires careful forethought with the end in mind—ultimately, the dental providers involved want the resulting appearance after braces to look as natural as possible. For that reason, dentists usually choose teeth for extraction that are outside of the "smile zone" (the teeth visible while smiling) like premolars and molars.
Additionally, dentists are concerned about bone loss after extracting the teeth. Bone often diminishes around empty tooth sockets, especially if those sockets were damaged during extraction. This loss in bone can weaken the jaw structure and cause significant problems while moving teeth with braces.
To avoid this, dentists take great care during tooth removal not to damage the socket. Additionally, they may place a bone graft within the socket immediately after removing the tooth, especially if the space will remain vacant for a significant period of time. A bone graft serves as a scaffold upon which new bone cells can form and accumulate.
After the extractions, the orthodontist may then proceed with correcting the bite. Patients may also need some form of prosthetic teeth to fill in the spaces while wearing braces. Often prosthetic teeth can be incorporated with the braces for a more natural look. After braces, any remaining gaps may require further restoration, either with dentures, bridges or, later in adulthood, dental implants.
Complex bite problems like crowding pose unique challenges in correcting them. But using techniques like tooth extraction can help achieve a successful and satisfactory outcome.

We instinctively know when a smile looks normal—and when it doesn't. It could be that something simply looks out of place like crooked teeth. But we might also notice when something is missing—as with one or both of the canine teeth.
The canine teeth align just under the eyes and are recognizable by their pointed ends. When they're missing, the smile looks “incomplete.” But “missing” in this case could mean “invisible”—the teeth are there, but hidden within the gums because they failed to come in properly and became impacted. This often happens on a smaller jaw where other teeth have crowded into the space intended for them.
Fortunately, we may have a remedy, and not just for appearance's sake—any impacted tooth can cause health problems, from gum abscesses to root damage of neighboring teeth. Although this might necessitate their surgical removal, we might also be able to coax them through the gums into better position in the jaw, if they're in a reasonably good position. This could result in both a boost to a patient's oral health and a more normal looking smile.
First, though, a patient will need to undergo a thorough bite evaluation by an orthodontist. Besides pinpointing the impacted teeth's precise location with x-rays or CT technology, an orthodontist will also want to assess the positions and condition of the rest of the teeth. If the conditions are right and there's enough room in the jaw, the orthodontist may recommend drawing the impacted canines into proper alignment in the jaw.
The process starts when an oral surgeon exposes the impacted teeth by surgically cutting through the gum tissue. They then attach a small bracket to the tooth with a tiny metal chain attached, the other end of which is looped over orthodontic hardware attached to other teeth. The tension on the chain by the hardware gradually nudges the teeth downward out of the gums. This is usually done in coordination with other measures to fully correct the bite.
If the procedure is successful, bringing the canines out of impaction reduces the problems those teeth could cause the person's oral health. But just as important, it can restore normality to their smile.

Dentists remove millions of teeth each year, often because of tooth decay or gum disease. But disease isn't the only reason—a tooth extraction might make it easier to straighten a crooked smile.
Realigning teeth for therapeutic or cosmetic reasons is a regular undertaking in dentistry, but the process itself often differs from person to person. Each individual patient requires their own treatment plan taking into account factors like the kind of bite problem involved, the size of the jaw and the space available to move teeth.
This plan could indeed involve removing teeth. For example, an abnormally small jaw could cause crowding. Not only can crowding move teeth out of position, it may also leave little to no room for moving teeth. Although dentists can minimize crowding by influencing jaw development in early childhood, removing teeth for more space is usually the only option available to older adolescents and adults.
Similarly, teeth can fail to erupt properly and remain partially or fully submerged beneath the gums (known as impaction). There is an orthodontic method for pulling an impacted tooth fully onto the jaw, but only if the tooth isn't too far out of alignment. Otherwise, it may be better to remove the impacted tooth and then correct any gaps with braces or a dental implant.
There's also a situation on the opposite side of the spectrum that could benefit from teeth removal—when one or more permanent teeth fail to form, known as congenitally missing teeth. This can cause gaps in the smile or a “lopsided” appearance where a tooth on one side of the jaw is present while its counterpart on the opposite side of the jaw is missing.
The missing tooth can be replaced by an implant, bridge or other restoration. But another option may be to remove the existing counterpart tooth, and then close the gaps. This can result in a much more attractive smile that might be simpler and less costly than replacing the missing tooth.
Again, the decision to remove teeth to improve smile appearance depends on the patient and their particular dental condition. But in the right situation, it could make straightening a smile easier and more effective.

If your child has seen the dentist regularly, and brushed and flossed daily, there's a good chance they've avoided advanced tooth decay. But another problem might already be growing right under your nose—a poor dental bite (malocclusion).
A dental bite refers to the way the upper and lower teeth fit together. In a normal bite the teeth are in straight alignment, and the upper teeth slightly extend in front of and over the lower when the jaws are shut. But permanent teeth erupting out of position or a jaw developing abnormally can set the stage for a malocclusion.
Although the full effects of a malocclusion may not manifest until later, there may be signs of its development as early as age 6. If so, it may be possible to identify a budding bite problem and “intercept” it before it goes too far, correcting it or reducing its severity.
Here are 6 signs your school-age child could be developing a malocclusion.
Excessive spacing. If the spacing between teeth seems too wide, it could mean the size of your child's teeth are out of proportion with their jaw.
Underbite. Rather than the normal upper front teeth covering the lower, the lower teeth extend out and over the upper teeth.
Open bite. There's a space or gap between the upper and lower teeth even when the jaws are shut.
Crowding. Due to a lack of space on the jaw, incoming teeth don't have enough room to erupt and may come in misaligned or “crooked.”
Crossbites. Some of the lower teeth, either in front or back of the jaw, overlap the upper teeth, while the rest of the upper teeth overlap normally.
Protrusion or retrusion. This occurs if the upper front teeth or jaw appear too far forward (protrusion) or the lower teeth or jaw are positioned too far back (retrusion).
Besides watching out for the preceding signs yourself, it's also a good idea to have your child undergo a comprehensive bite evaluation with an orthodontist around age 6. If that does reveal something amiss with their bite, intervention now could correct or lessen the problem and future treatment efforts later.
You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.
That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.
The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.
That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.
But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.
Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.
Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.
