Braces utilize the mouth’s existing teeth-moving mechanism by applying pressure in the direction of the desired movement. This is done with a wire laced through metal brackets affixed to the outside of the teeth that’s then usually anchored to brackets on the back teeth to maintain constant tension.
This anchorage set-up alone, however, may not work effectively with all bite situations, which might require other points of anchorage. That’s where these other tools in the orthodontist’s toolkit can come in handy.
Headgear. These appliances not only aid with moving teeth but they also help influence the proper growth of facial structures (as when one of the jaws is too far forward or too far back). Because of this influence on jaw growth you’ll only find them used with pre-teens. The most typical application is a strap running around the back of the head or neck (or sometimes over the chin or forehead) that attaches in the front to brackets usually bonded to the molars. In this case the back of the patient’s skull serves as the anchor point.
Temporary anchorage devices (TADs). Orthodontists sometimes wish to isolate the teeth to be moved from nearby teeth that shouldn’t be. For example, they may want to move front teeth back to close a space without the back teeth moving forward. In this case, it may be necessary to create a separate anchorage point in the jaw. This can be done with TADs, which are made of either biotolerant (stainless steel, chromiumâ??cobalt alloy), bioinert (titanium, carbon), or bioactive (hydroxyapatite, ceramic oxidized aluminum) materials and shaped like mini-screws. Orthodontists insert them into the bone and then attach them to the braces using elastics (rubber bands). After completing orthodontic treatment they’re easily removed.
Elastics. We’ve already mentioned them, but elastics deserve their own category because they can be used in various kinds of anchorage. They play an important role, for example, in cross-arch anchorage that maintains tension between the upper and lower jaws. They can also be used to help move one or more groups of teeth — or isolate certain teeth from moving. They truly are flexible (no pun intended) in their uses for fine-tuned tooth movement.
All these devices can be used in various combinations to match and correct whatever bite situation a patient may have. The end result is straighter and better-functioning teeth — and a more attractive smile.

Is a chipped tooth big news? It is if you’re Justin Bieber. When the pop singer recently posted a picture from the dental office to his instagram account, it got over 2.6 million “likes.” The snapshot shows him reclining in the chair, making peace signs with his hands as he opens wide; meanwhile, his dentist is busy working on his smile. The caption reads: “I chipped my tooth.”
Bieber may have a few more social media followers than the average person, but his dental problem is not unique. Sports injuries, mishaps at home, playground accidents and auto collisions are among the more common causes of dental trauma.
Some dental problems need to be treated as soon as possible, while others can wait a few days. Do you know which is which? Here are some basic guidelines:
A tooth that’s knocked out needs attention right away. First, try and locate the missing tooth and gently clean it with water — but avoid holding the tooth’s roots. Next, grasp the crown of the tooth and place it back in the socket facing the correct way. If that isn’t possible, place it between the cheek and gum, in a plastic bag with the patient’s saliva or a special tooth preservative, or in a glass of cold milk. Then rush to the dental office or emergency room right away. For the best chance of saving the tooth, it should be treated within five minutes.
If a tooth is loosened or displaced (pushed sideways, deeper into or out of its socket), it’s best to seek dental treatment within 6 hours. A complete examination will be needed to find out exactly what’s wrong and how best to treat it. Loosened or displaced teeth may be splinted to give them stability while they heal. In some situations, a root canal may be necessary to save the tooth.
Broken or fractured (cracked) teeth should receive treatment within 12 hours. If the injury extends into the tooth’s inner pulp tissue, root canal treatment will be needed. Depending on the severity of the injury, the tooth may need a crown (cap) to restore its function and appearance. If pieces of the tooth have been recovered, bring them with you to the office.
Chipped teeth are among the most common dental injuries, and can generally be restored successfully. Minor chips or rough edges can be polished off with a dental instrument. Teeth with slightly larger chips can often be restored via cosmetic bonding with tooth-colored resins. When more of the tooth structure is missing, the best solution may be porcelain veneers or crowns. These procedures can generally be accomplished at a scheduled office visit. However, if the tooth is painful, sensitive to heat or cold or producing other symptoms, don’t wait for an appointment — seek help right away.
Justin Bieber earned lots of “likes” by sharing a picture from the dental office. But maybe the take-home from his post is this: If you have a dental injury, be sure to get treatment when it’s needed. The ability to restore a damaged smile is one of the best things about modern dentistry.

Chronic pain can turn your life upside down. While there are a number of disorders that fit in this category, two of them—fibromyalgia and temporomandibular disorders (TMD)—can disrupt your quality of life to the extreme. And it may be the two conditions have more in common than similar symptoms—according to one study, three-fourths of patients diagnosed with fibromyalgia show symptoms of TMD.
To understand why this is, let’s take a closer look at these two conditions.
Fibromyalgia presents as widespread pain, aching or stiffness in the muscles and joints. Patients may also have general fatigue, sleep problems, mood swings or memory failures. TMD is a group of conditions that often result in pain and impairment of the temporomandibular joints that join the jaw with the skull. TMD can make normal activities like chewing, speaking or even yawning painful and difficult to do.
Researchers are now focusing on what may, if anything, connect these two conditions. Fibromyalgia is now believed to be an impairment of the central nervous system within the brain rather than a problem with individual nerves. One theory holds that the body has imbalances in its neurotransmitters, which interfere with the brain’s pain processing.
Researchers have also found fibromyalgia patients with TMD have an increased sensitivity overall than those without the conditions. In the end, it may be influenced by genetics as more women than men are prone to have either of the conditions.
Treating these conditions is a matter of management. Although invasive techniques like jaw surgery for TMD are possible, the results (which are permanent) have been inconclusive in their effectiveness for relieving pain. We usually recommend patients try more conservative means first to lessen pain and difficulties, including soft foods, physical therapy, stretching exercises and muscle relaxant medication. Since stress is a major factor in both conditions, learning and practicing relaxation techniques may also be beneficial.
In similar ways, these techniques plus medication or cognitive-behavioral therapy that may influence neurotransmission can also help relieve symptoms of fibromyalgia. Be sure then that you consult with both your physician and dentist caring for both these diseases for the right approach for you to help relieve the effects of these two debilitating conditions.
