Braces are a common part of many teenagers’ life experience — but not every bite problem is alike. Sometimes, there’s a need for accurately moving only a few teeth while making sure others don’t. This is where Temporary Anchorage Devices (TADs) can help streamline that effort and even reduce treatment time.
Orthodontics wouldn’t work at all if we didn’t already have a natural tooth movement mechanism in our mouths. That ability rests with the periodontal ligament, a tough, elastic tissue between the teeth and the bone that firmly attaches to both with tiny collagen fibers. Though quite secure in holding teeth in place, the ligament attachment also allows teeth to move in response to changes in the bone and jaw structure.
Braces are made of brackets cemented to tooth surfaces through which tiny wires pass. The wires are anchored, usually to other teeth or groups of teeth, and tightened to apply pressure against the other teeth. The ligament does the rest: as the teeth are “pressured” to move in a certain direction, new bone, ligament and an anchoring substance known as cementum forms behind it to secure the tooth in its new position.
The anchorage teeth are not intended to move. In some situations, though, it’s difficult to keep them from not moving — much like trying to keep a boat anchor from not dragging through sand on the sea bottom. TADs help alleviate this problem: it’s a mini-screw or mini-implant that’s temporarily placed in the jawbone to which the tension wire can be secured. They’re placed in the best positions for isolating the teeth that need to be moved without compromising the position of nearby teeth that don’t.
With the site numbed with a local anesthetic, we install the TAD through the gum tissue into the bone with a special device; their screw-shaped design holds them securely in place. They’re then removed when the orthodontic treatment is complete.
While a simple procedure, precise placement requires collaboration between the orthodontist and the oral surgeon or dentist who installs them. They also need special attention during daily hygiene to keep them clean. Still, with difficult bite situations they can help bring about the right outcome — a straight and beautiful smile.

It’s something you think about often—especially when you look in a mirror or at a photo of yourself. You wish something could have been done about it a long time ago. But now you think you’re too old to correct your misaligned teeth—your “crooked” smile.
Actually, you can transform your smile through orthodontics, whatever your age. Millions of your peers have done just that—currently, an estimated one in five orthodontic patients is an adult.
If orthodontics isn’t right for you it won’t be because of age, but most likely the condition of your gums and underlying bone or your overall health. That first factor is extremely important: if you’ve lost a significant amount of bone due to periodontal (gum) disease, there may not be enough to support the force of moving the teeth during orthodontics.
Health conditions like severe heart-valve disease, uncontrolled diabetes or drugs to treat arthritis or osteoporosis can also make tooth movement difficult. And, if you have restricted saliva flow (dry mouth), wearing orthodontic devices could be uncomfortable and increase your risk of tooth decay.
If, however, your mouth and body are reasonably healthy (and you don’t have a difficult bite problem to correct), there’s no reason why you can’t undergo orthodontic treatment. The only other thing that might hold you back is concern over your appearance during treatment. Many adults balk at the possible embarrassment of wearing metal braces “at their age.”
If this is a concern, you may have an alternative: clear aligners. These are a series of computer-generated clear plastic trays that conform to the individual contours of your teeth. Each tray is slightly different—you wear one for a short period of time (usually two weeks) before moving on to the next tray to successively and gradually move your teeth. They’re nearly invisible to others and, unlike fixed metal braces, you can take them out for a rare special occasion.
The only way you’ll know whether correcting your misaligned teeth is a viable option is to undergo a full orthodontic evaluation. From there we can help you decide if and how you want to gain a straighter, more attractive smile.

While crooked teeth are usually responsible for a malocclusion (poor bite), the root cause could go deeper: a malformed maxilla, a composite structure composed of the upper jaw and palate. If that’s the case, it will take more than braces to correct the bite.
The maxilla actually begins as two bones that fit together along a center line in the roof of the mouth called the midline suture, running back to front in the mouth. The suture remains open in young children to allow for jaw growth, but eventually fuses during adolescence.
Problems arise, though, when these bones don’t fully develop. This can cause the jaw to become too narrow and lead to crowding among the erupting teeth and a compromised airway that can lead to obstructive sleep apnea. This can create a cross-bite where the upper back teeth bite inside their lower counterparts, the opposite of normal.
We can remedy this by stimulating more bone growth along the midline suture before it fuses, resulting in a wider maxilla. We do this by installing a palatal expander, an appliance that incrementally widens the suture to encourage bone formation in the gap, which over time will widen the jaw.
An expander is a metal device with “legs” extending out on both sides and whose ends fit along the inside of the teeth. A gear mechanism in the center extends the legs to push against the teeth on both sides of the jaw. Each day the patient or caregiver uses a key to give the gear a quarter turn to extend the legs a little more and widen the suture gap. We remove the expander once the jaw widens to the appropriate distance.
A palatal expander is an effective, cost-efficient way to improve a bite caused by a narrow jaw, but only if attempted before the bones fuse. Widening the jaw after fusion requires surgery to separate the bones — a much more involved and expensive process.
To make sure your child is on the right track with their bite be sure to see an orthodontist for an evaluation around age 6. Doing so will make it easier to intervene at the proper time with treatments like a palatal expander, and perhaps correct bite problems before they become more expensive to treat.

Have you started orthodontic treatment recently? Are you having a little trouble getting used to your braces? If so, you are not alone: Everybody goes through an adjustment period during which they momentarily wonder if they’ll really ever get used to this. Don’t worry — you will! And we’ve never heard anyone say, on the day their braces come off and their new smile is revealed, that they aren’t glad they went the distance. Just ask Houston Rockets all-star center Dwight Howard, who discussed his own orthodontic treatment in a recent interview.
“I’m sure I was no different than anyone else who has ever had braces,” he told Mediaplanet. “At first I hated them so much… That changed once I got used to them and I actually grew to love them.” What’s Howard’s advice? “Do exactly what your orthodontist says and know that the outcome is well worth it in the end.” We couldn’t agree more! Here are some tips for wearing braces comfortably:
- Hard & Chewy Foods: If you love fresh fruits and vegetables, that’s great; there’s no reason to give them up, just the really hard ones. You don’t want to bite into an apple or carrot or any other hard foods like bagels and pizza that have any “size” to them. Small pieces may be ok as long as they can’t bend your wires. Chewy, sticky candy should really be avoided completely. Same with soda, sports drinks and so-called energy drinks because they contain acids that promote tooth decay and can cause a lot of damage around the braces.
- Effective Oral Hygiene: Keeping your teeth clean is more important than ever, but also more challenging than ever. It’s easy for food to get stuck under wires and around brackets, but failing to remove it can cause tooth decay, gum irritation and soreness. Therefore, the cleaner your teeth and your braces are, the healthier you will be. Use interdental cleaning brushes and/or a floss-threader to get behind your wires. A mouthrinse can also help strengthen teeth and keep bacteria in check. If you have any questions about how to clean between your teeth, please ask for a demonstration at your next visit.
- Pain Relief: Some soreness at the beginning of orthodontic treatment is normal. To relieve it, you can use an over-the-counter pain reliever and/or a warm washcloth or heating pad placed on the outside of the jaw. If brackets or wires are rubbing against the inside of your cheeks or lips, try applying wax to these areas of your braces. If this does not offer enough relief, we may be able to trim the end of a poking wire. Call us if you need help with this.

A lot of time and effort goes into straightening your smile. But there’s a possibility it might not stay that way—and all that hard work could be lost. The same natural mechanism that enables your teeth to move with braces could cause them to revert to their old, undesirable positions.
So for a little while (or longer for some people) you’ll need to wear a retainer, an appliance designed to keep or “retain” your teeth where they are now. And while the removable type is perhaps the best known, there’s at least one other choice you might want to consider: a bonded retainer.
Just as its name implies, this retainer consists of a thin metal wire bonded to the back of the teeth with a composite material. Unlike the removable appliance, a bonded retainer is fixed and can only be removed by an orthodontist.
Bonded retainers have several advantages. Perhaps the most important one is cosmetic—unlike the removable version, others can’t see a bonded retainer since it’s hidden behind the teeth. There’s also no keeping up with it—or losing it—since it’s fixed in place, which might be helpful with some younger patients who need reminding about keeping their retainer in their mouth.
There are, however, a few disadvantages. It’s much harder to floss with a bonded retainer, which could increase the risks of dental disease. It’s also possible for it to break, in which case it will need to be repaired by an orthodontist and as soon as possible. Without it in place for any length of time the teeth could move out of alignment.
If you or a family member is about to have braces removed, you’ll soon need to make a decision on which retainer to use. We’ll discuss these options with you and help you choose the one—removable or bonded—that’s right for you.
