As a basic orthodontic appliance, braces are what allows us to move teeth into better positions to improve a person’s bite. In certain cases, though, this treatment application gets a little assistance from Temporary Anchorage Devices (TADs) to improve accuracy and reduce treatment time.
Braces take advantage of our teeth’s natural ability to move. Teeth are held in place within the bone by the periodontal ligament, an elastic tissue that attaches to the teeth with microscopic fibers secured by a hardened substance called cementum. The periodontal ligament is constantly remodeling in response to changes in the mouth. As pressure is placed on a tooth, new bone, ligament and cementum are formed on the “pulling” side of the tooth; on the other side, the bone and ligament dissolve (resorb), allowing the tooth to move in that direction.
Braces allow this natural process to occur with controlled forces applied by thin flexible wires threaded through the small brackets attached to the front of the teeth and then affixed or “anchored” to other teeth. By attaching the teeth to the other teeth by wires running through all the brackets, “anchorage” is created to allow teeth to be moved where the dentist wants them to go. By adjusting the tension on the wires, we can apply light but constant pressure on the “unanchored” teeth to move them into a new desired position.
Teeth we do not want to move are referred to as the anchorage for teeth we do want to move. If, however, the situation calls for more precise isolation of teeth to be moved, TADs can be very useful. TADs are mini-implants imbedded in the bone to serve as anchorage at strategic locations in the mouth. In this way, the group of teeth to be moved receives forces that are applied through the additional anchorage provided by the TADs. That “tension” or “pressure” is applied only to them and not to adjacent teeth that should not move. This increases efficiency for tooth movement and helps reduce the treatment time.
TADs can be placed using local anesthesia and with little discomfort, and are removed when orthodontic treatment is completed. Although the procedure is pretty straightforward, it does require collaboration between orthodontist and surgeon to ensure correct positioning.
In the end, TADs increase our ability to control the forces that move teeth during orthodontic treatment. This lessens discomfort for the patient and helps ensure the end result — a more functional bite and a transformed smile.

Her parents Will and Jada are Hollywood royalty, who helped her land her first acting role when she was 7. She released a hit single, “Whip My Hair,” before she had quite reached the age of 10; shortly afterward, she was signed to a record label. Yet the young singer and actress Willow Smith has at least one thing in common with plenty of ‘tweens and teens across America: She needed to wear braces to correct problems with the alignment of her teeth.
Why do braces seem to be a part of growing up for so many kids? One answer is because they work so well. Braces apply gentle pressure to the teeth through a thin, flexible wire called an archwire. Attached to the teeth with a metal or ceramic bracket, the archwire exerts a light force which causes teeth to gradually move into better positions. Sometimes, when additional force is needed, elastic bands or other appliances may be used in conjunction with braces.
Most everyone is familiar with the silvery metal “tracks” of traditional braces. But did you know that there are a number of other options too? For a more inconspicuous look, you may be able to have braces with tooth-colored ceramic brackets; then, only the thin archwire will be visible in your mouth. It’s even possible in some cases to place the metal wires and brackets on the tongue side of the teeth. With this system, called lingual braces, the orthodontic hardware is truly invisible.
What if you didn’t need metal braces at all? Some people can get good results using a system of clear plastic aligners instead of braces. The aligners are worn 23 hours a day, but can be taken off for cleaning and for important events. They work best for correcting mild or moderate alignment problems.
Still, plenty of people feel that if they’re going to wear braces, they might as well flaunt them. That’s why some types of braces are available with bands that come in different colors. When Willow’s brother Jayden wore braces, he was reported to favor red and black ones. Jayden, who is about two years older than his sister, had his braces removed just before Willow got hers put on.
So if it turns out that you need braces, remember that lots of your favorite celebrities wore them too. And keep in mind that, depending on your own situation, you may have several options to choose from.
