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.

Some things in life are almost guaranteed to make you go, "Uh, oh"—your car won't start, your a/c goes out, or, worse yet, you get an unexpected letter from the IRS.
Here's another: One of your teeth is loose. And, if you don't act quickly, that loose tooth may soon become a lost tooth.
But first, we need to find out why it's loose. It's usually due to one of two types of injury related to your bite. One type is called primary occlusal trauma. This results from your teeth encountering higher than normal biting forces. This often happens if you habitually gnash or grind your teeth together outside of normal functions like eating or speaking.
The other type is secondary occlusal trauma. In this case, the supporting gum tissues and bone have been weakened or lost by disease, with the gum tissues possibly becoming detached. Without this support, even normal biting forces could loosen a tooth.
Our treatment approach for a loose tooth may differ depending on which of these is the cause. For primary occlusal trauma, we want to reduce the biting forces that have contributed to loosening the tooth. One way to do this is to create a mouthguard that when worn prevents teeth from making solid contact during grinding episodes.
For secondary trauma, we want to first focus on treating any gum disease responsible for weakening the gum tissues. Once we have it under control, the gums and bone tissues can heal and possibly regain and strengthen their attachment with the tooth.
At the same time, we may also need to stabilize a loose tooth to prevent its loss. This usually involves splinting, whereby we use neighboring healthy teeth to support the loose tooth. One way to do this is to attach a metal strip across the backs of the loose tooth and its more stable neighbors, or by way of a channel cut through the top biting surfaces of the teeth.
If a loose tooth regains its attachment with the gums and bone, it may stabilize and any splinting can be removed. If not, splinting may become a permanent solution. Either way, prompt treatment can help us save your loose tooth.

Braces are so common that we often view them as "ho-hum." But there are aspects about braces that make them remarkable. For one, the fact that we can move teeth at all is a wonder of nature.
We normally experience our teeth as firmly set in the jaw, which can easily lead to assuming they're permanently fixed to the bone. They're not. Teeth are actually held in place by a fibrous gum tissue called the periodontal ligament that lies between them and the jawbone. The ligament anchors to both with tiny fibers, which on the tooth side affixes within a thin substance called cementum deposited on the tooth root.
As we said, we don't normally notice teeth moving. But the periodontal ligament does allow movement on a miniscule scale as a response to normal pressures that accompany biting and chewing. Although we're unaware of it, this movement takes place as the bone and cementum ahead of the direction of movement begin to dissolve. Simultaneously, new bone and cementum develops on the other side of the tooth to stabilize the movement.
Orthodontic treatment takes advantage of this natural process. The anchored wires of braces through attached brackets place pressure on the teeth in the intended direction for tooth movement. The natural mechanism described earlier does the rest. Over time, orthodontists have developed an amazing amount of precision working within this mechanism.
Another aspect about braces and other methods we may take for granted is our motive for even trying to move teeth in the first place. It may seem we're only realigning teeth to produce a more attractive smile—which they can do and why we often refer to braces as the "original smile makeover." But there's an even greater desire—straightening teeth can improve dental health.
Poor bites in turn cause other problems. Misaligned teeth are more difficult to keep clean of bacterial plaque, which increases the risk of disease. A poor bite can also accelerate teeth wear and contribute to gum problems like recession. We can eliminate or minimize these problems through bite correction.
Whatever your age, braces or other means can vastly benefit your health and your appearance. They may not always seem so, but braces are one of the true wonders of dental care.
