Before we begin correcting a malocclusion (poor dental bite), we need to ask a few questions: How extensive is the malocclusion? How far must we move the teeth to correct it? How might the patient's jaw size impact treatment?
Answering these and other questions help us develop an effective treatment plan. And depending on the answers, we might need to look at other procedures before we install braces—like removing one or more of the teeth.
This isn't a subject to approach lightly: All teeth play an important role in dental function and smile appearance, and ordinarily we want to preserve teeth, not remove them. Sometimes, however, it may be a necessary action to achieve our goal of an improved dental bite.
For example, it might be necessary for correcting a malocclusion caused by severe teeth crowding. This occurs when one or both of the jaws hasn't grown to a sufficient size to accommodate all of the teeth erupting on it. As a result, some of the teeth could come in out of their proper alignment.
If caught early before puberty, we may be able to use other techniques to alleviate crowding, like a device called a palatal expander that influences an upper jaw to widen as it grows. If successful, it could provide later teeth more room to erupt in their proper positions.
But even if additional jaw growth occurs, it may not be enough to avoid a malocclusion or treatment with braces. Alleviating further crowding by removing teeth in little noticed areas could help with subsequent orthodontics.
Removing teeth may also be the answer for other problems like an impacted tooth, in which the tooth has not fully erupted and remains submerged in the gums. It's sometimes possible to use a technique to “pull” the tooth down where it should be; but again, that will still require jaw space that may not be available. The more effective course might be to remove the impacted tooth.
Whether or not tooth extraction will be needed can depend on a thorough orthodontic evaluation and full consideration of all the available options. Even though the ideal situation is to correct a bite with all teeth present and accounted for, it may be for the better good to sacrifice some.

Teeth crowding is a difficult bite problem (malocclusion) that often involves the entire jaw structure to be evaluated. Normally occurring when the jaw doesn’t have adequate space for normal tooth eruption, teeth coming in later put pressure on other teeth, causing them to develop improperly.
Crowding also makes it difficult to realign teeth with braces because there’s simply not enough room for sufficient movement to take place. The solution may then be to consider the removal of some of the teeth to create enough space for orthodontic treatment.
Not just any tooth can be removed, however — we must first conduct a careful analysis to determine which can be removed to facilitate optimum movement of the remaining teeth without disrupting normal mouth function or affecting appearance. The teeth most frequently removed for this purpose are the bicuspids, located between the cuspids or eyeteeth (which are positioned directly under the eyes) and the molars, the largest teeth in the back of the mouth. Sometimes one premolar tooth on each side of the jaw can be removed without sacrificing future form or function.
There are a few important considerations we must keep in mind when extracting teeth for orthodontic reasons; perhaps the most important is preserving bone at the extraction site. Because continuing bone growth depends on the forces generated by teeth when we bite or chew, bone near a missing tooth socket will tend to diminish over time. If there’s insufficient bone during orthodontic treatment, it may result in gum recession and root exposure — not only damaging to the teeth themselves but also to a person’s smile appearance. To avoid this, we sometimes will consider inserting a bone graft, which will stimulate bone growth, into the empty socket immediately after extraction. While this isn’t commonly done, it’s being considered if the patient’s bone is thin and a concern during healing.
We must also consider how to accommodate other, unrelated tooth loss to assure the final result is visually appealing. It may be necessary in these cases to maintain the space at the missing tooth site for a future restoration once the orthodontics is completed. This takes planning as well as the use of restorations like dental implants, bridges or partial dentures.
Regardless of your bite issues, the field of orthodontics has the appliances and techniques to overcome even the most complicated condition. When necessary, using procedures like tooth extraction can help turn an unappealing, dysfunctional bite problem into a beautiful smile.

When a tooth is beyond repair due to disease or injury, it may be necessary to remove it. A “simple” tooth extraction is among the most common in dentistry and certainly not the agonizing procedure depicted in common lore.
They’re referred to as simple extractions because the shape of the tooth and root allows for a fairly straightforward and uncomplicated removal. An example would be the normally cone-shaped upper front tooth that doesn’t offer a lot of resistance during the extraction process.
The process itself is fairly straightforward. Teeth are held in place by the periodontal ligament, an elastic tissue made of tiny fibers that attaches the tooth to the supporting bone. These fibers can be dislodged from the tooth with some careful manipulation — in the hands of an experienced dentist there’s a deft “feel” to the fibers loosening. Once they’ve detached, it requires little effort to remove the tooth; with the aid of local anesthesia, you won’t feel anything but a little pressure.
Immediately after the tooth is removed, we commonly insert bone grafting material in the socket to minimize bone loss until a permanent replacement like a dental implant can be installed after tissue healing. We then place sterile gauze over the site for a few minutes to control bleeding and, depending on the size of the wound opening, we may also place a few stitches to close it. We then give you instructions for caring and cleaning the site over the next few days, and prescribe antibiotics to reduce the chance of infection and anti-inflammatory drugs for any discomfort.
Although a simple extraction is a routine procedure, it’s important to perform a proper assessment of the tooth and the surrounding bone beforehand, including x-rays to determine the tooth’s exact shape and position. If we discover a complication that makes a simple extraction impractical (like multiple roots at acute angles), we may then refer you to an oral surgeon for a more complicated surgical extraction.
It’s our hope you’ll have your natural teeth for as long as you live. But if you must have one removed, you can rest assured it’s a common — and uneventful — experience.

“To gain something, sometimes you have to give up something else.”
No, that isn't the latest viral meme on the Internet. It's actually a practical consideration that could arise in orthodontics.
In this case, the “something” to gain is a straighter, more attractive smile; the “something” you may have to part with is a few teeth. This may be necessary if there are too many teeth on a dental arch for its capacity, a situation called crowding. A lack of space is the main reason teeth come in misaligned.
Before we can correct this, we'll need to free up space to allow for tooth movement by removing one or more of the existing teeth. The ideal candidates are those that are near to the teeth we wish to move but not highly visible. The first bicuspids are the most frequent choices for removal: they're located behind the cuspids or eyeteeth (the pointed teeth right under the eyes).
Ideally, we'll remove the target teeth some time before we apply braces to give the gums a chance to heal. At the same time we want to preserve the bone that once supported the teeth we've extracted. This is because when we chew the forces generated by the teeth stimulates bone replacement growth. When a tooth is no longer there the supporting bone doesn't receive this stimulation and may ultimately reduce in volume.
We may try to prevent this by placing a bone graft in the empty socket immediately after removing the tooth. The graft serves as a scaffold to encourage new bone to grow. Hopefully when we're ready to apply braces, the bone will be strong and healthy to handle the movement of the teeth.
As the teeth move under the influence of braces, they'll begin to fill up the space created by tooth removal. Once it's completed, the extracted teeth won't be missed — the other teeth now straightened will completely fill out the smile.
The different steps in this process must be carefully planned and executed precisely, and it will take months or even years to complete. In the end, though, this complicated bite problem can be corrected and replaced with an attractive, straight smile.
