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.

Gum disease is a bigger problem than you might think. More than half of all adults over age 30 have it, and that figure jumps to 70% of adults over 65. If left untreated, gum (periodontal) disease can eventually loosen teeth and cause them to fall out. It can also cause health issues outside of the mouth, including an increased risk of heart disease and other systemic health conditions.
But the good news is that gum disease can be treated—and even better, prevented! Since September is National Gum Care Month, it’s a good time to answer some frequently asked questions about gum disease:
What causes gum disease?
Gum disease is caused by certain types of harmful oral bacteria that live in a sticky film called dental plaque that collects on teeth both above and below the gum line. If this film is not cleaned effectively each day, it can eventually harden into a substance called tartar that can only be removed by a dental professional. As your body tries to fight the bacteria and the toxins they produce, your gums can become inflamed and may start to pull away from the teeth. Eventually, bone beneath the gums can start to break down and with continued bone loss, the teeth could be lost.
How do I know if I have it?
Gum disease doesn’t always produce symptoms—especially in smokers. Smoking hides the symptoms of gum disease because nicotine reduces blood flow to the area. However, there are things you should look out for. Gingivitis, a mild form of gum disease, can produce red and/or puffy gums that bleed when you brush or floss. Signs of periodontitis, a more serious form of the disease, include gum recession, bad mouth odors or tastes, and tooth looseness. But the only way to truly know if you have gum disease is to come in for an exam.
What can I do about it?
If you have gingivitis, a professional teeth cleaning and a renewed commitment to oral hygiene at home—including daily flossing and rinsing with antibacterial mouthwash—may be all you need to turn the situation around. Periodontitis may require a variety of treatments, ranging from special cleaning procedures of the tooth root surfaces to gum surgery. The first step toward controlling gum disease is visiting the dental office for an exam.
How can I prevent it?
Regular professional teeth cleanings and meticulous oral hygiene at home are your best defenses against gum disease. Avoid sugary drinks and snacks—which feed the disease-causing bacteria in your mouth—and tobacco in all forms. If you have diabetes, do your best to manage it well because uncontrolled diabetes can worsen periodontal disease.
