“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.

Although usually an orderly process, some permanent teeth don't come in as they should. In fact, they may not come in at all and remain hidden in the gum — a situation called impaction. This creates multiple problems for function, health and, in the case of front canines, appearance.
Canines are the longer and more pointed teeth on each side of the front-most incisors. They help tear and cut food during chewing, a function impaction eliminates. Besides a higher risk for developing abscesses (isolated areas of infection) and cysts, they can also put pressure on neighboring teeth and damage their roots or cause them to erupt abnormally.
Dentists often remove impacted wisdom and other back teeth to lessen these potential problems. Removing canines, though, has additional considerations: besides compromising ideal chewing function, missing canines often create an unattractive smile.
But before considering removal, there's another technique we might be able to use to save the canines and actually draw them down through the gums to their correct position. It's usually part of an overall orthodontic plan to correct a poor bite (malocclusion).
After pinpointing their exact position with x-rays or CT scanning, a surgeon surgically exposes the impacted canines' crowns through the gums. They then bond small brackets to the crowns and attach a small gold chain to each bracket. They fasten the other end of the chains to orthodontic hardware that exerts downward pressure on the impacted teeth. Over several months this pressure can help move the teeth into their normal positions.
Unfortunately, this technique isn't always advisable: one or more of the impacted teeth may be in a difficult position to attempt it. It's usually best in these situations to remove the teeth, usually sooner rather than later for the sake of neighboring teeth.
Fortunately, with today's advanced restorative techniques, we can eventually replace the canines with dental implants, although that's best undertaken after the patient enters adulthood. In the meantime, we can utilize orthodontic means to preserve the open space and provide a temporary restorative solution.
Whatever route taken, these teeth don't have to become a source of problems, especially for your appearance. Whether through orthodontics or restorative dentistry, impacted canines don't have to ruin your smile.
