We treat most malocclusions (bad bites) with braces or clear aligners. But not all malocclusions are alike — some can require extra procedures to achieve successful results.
One such example is when incoming teeth crowd other teeth and cause them to erupt abnormally. The crowding also reduces the space needed to move the misaligned teeth to better positions. To make more room we'll often remove some of the teeth before undertaking orthodontics.
The key is to extract the right teeth. The best candidates are those whose absence will have minimal effect on both appearance and dental function. That's commonly the bicuspids, located right on the edge of the “smile zone” (the teeth most visible when we smile) between the cuspid (eye) teeth and the back molars.
Once we choose and remove the teeth our next concern is to protect the bone at the extraction site.Â The bone in our jaws benefits from the pressure created when we bite or chew. This stimulates new bone cells to form and replace older cells. Without it, as when we have a missing tooth, the amount of bone can diminish over time and affect the success of any future orthodontics.
To prevent this, we take care not to damage the gums and bone removing the tooth. We may also install a graft under the empty socket to encourage bone growth.
If we've removed teeth outside the smile zone, the resulting orthodontics will move teeth into the opened space. In the end, you won't even notice they're gone. Teeth lost or congenitally missing in the smile zone, though, may eventually require a replacement tooth. A dental implant is the best choice, but it should be put on hold for a younger person until their jaw has fully developed.
In the meantime, we can install a spacer or a temporary restoration to hold the empty space and prevent other teeth from drifting into it. This can be incorporated into braces or aligners, or with a removable partial denture or a temporary modified bridge.
Extracting teeth to aid orthodontics first requires a well-laid plan that could encompass several years. The end result, though, can be well worth the time and effort — better function and a new, attractive smile.

In a normal bite, the upper and lower teeth line up and fit together when you close your jaws. When they don’t, you have a poor bite or “malocclusion.” The most common cause is teeth out of position, which can be corrected by moving them with braces.
Sometimes, though, the size and position of the jaws is the primary cause for the malocclusion and not the teeth. If the discrepancy is minor, tooth movement alone might be sufficient; but if there’s a wide discrepancy in the symmetry of the face or the size of one jaw over the other then a surgical solution may be necessary. One common procedure is orthognathic surgery, which literally means to “straighten the jaw.”
A wide range of irregularities — both minor and major — can be corrected by adjusting and realigning the bone in the jaw. While orthognathic surgery can certainly improve your facial profile and smile, its main purpose is to restore function that’s been lost due to poor jaw alignment. Candidates for the surgery have difficulty chewing, biting or swallowing food, chronic pain or headaches related to the jaw joints, chronic mouth breathing and dry mouth, or sleep apnea.
In many cases, treatment involving orthognathic surgery requires a team approach between orthodontist, oral surgeon and general dentist. While the surgeon surgically alters and repairs the jaw or facial structure, the services of an orthodontist may still be needed to move teeth misaligned due to the underlying problem with the jaw structure. The general dentist ensures teeth and gums remain healthy during all the other treatment phases.
Orthognathic surgery can benefit both oral and general health, as well as improve the appearance of the entire face. The process, however, can be complicated: you or your family member will need to undergo a thorough examination to determine if you or they are a good candidate for the surgery. If so, the end result can be life-changing.
