Applying braces or clear aligners to move misaligned teeth is only part of an orthodontist's overall mission to eliminate poor bites (malocclusions). Sometimes a malocclusion isn't caused by the teeth at all—the size of the jaw is the problem!
One type in particular, a cross-bite, often happens because the upper jaw has developed too narrowly. As a result, many of the upper teeth fit inside the lower, the opposite of normal. But a tool called a palatal expander can alleviate the problem if it's applied at an early enough age.
The device works because the upper jawbone initially forms as two halves that fit together along a center line in the roof of the mouth (the palate) running from the back of the mouth to the front. These two bone halves remain separate during childhood to facilitate jaw growth, but eventually fuse around puberty.
Consisting of two sets of wire arms joined together by a hinge mechanism in the middle, the expander device is positioned up against the palate. The orthodontist extends each arm to press against the inside of the back teeth, then adds more outward pressure by turning the mechanism in the middle with a small key. During wear, the patient or caregiver will turn the mechanism in the same way to keep up the pressure on the two sides of the jaw.
This continual pressure keeps the two bones moving away from each other and maintaining a center gap between them. In response, more bone forms on the two halves to fill the gap. In time, the newly formed bone should widen the jaw enough to correct any developing malocclusion.
Timing is everything with a palatal expander—if not used before the jaw bones fuse, the patient will need a surgical procedure to separate the bones to pursue treatment. To catch the problem early enough, children should have an orthodontic evaluation on or before they turn six. An orthodontist may be able to identify this or other emerging bite problems and intervene before it becomes worse. Taking this approach can help save you and your child more expensive orthodontic treatment down the road.

In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.
When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”
Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.
There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.
By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.
So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.

You can learn more about this topic in the Dear Doctor magazine articles “Why Orthodontic Retainers?” and “The Importance of Orthodontic Retainers.” The interview with Kathy Bates appears in the latest issue of Dear Doctor.
If you press your tongue against your teeth, unless something is badly wrong they won't budge. In fact, your teeth are subjected to a fair amount of pressure each day as you chew and eat, and yet they remain firmly in place.
But there's a deeper reality—your teeth do move! No, it's not a paradox—the gum and bone tissues that hold your teeth in place allow for slight, imperceptible changes in the teeth's position. Their natural ability to move is also the basis for orthodontics. Here are 3 more facts you may not know about your teeth's natural ability to move.
Teeth are always on the move. Teeth are held firmly within the jawbone by an elastic gum tissue called the periodontal ligament and a thin layer of bony-like material called cementum. In response to pressure changes, though, the bone dissolves on the side of the teeth in the direction of pressure and then rebuilds behind it, solidifying the teeth's new position, a process that happens quite slowly and incrementally. And it will happen for most of us—some studies indicate more than 70% of people will see significant changes in their bite as they age.
Orthodontics works with the process. Orthodontic appliances like braces or clear aligners apply targeted pressure in the direction the orthodontist intends the teeth to move—the natural movement process does the rest. In the case of braces, a thin metal wire is laced through brackets bonded to the front of the teeth and then anchored, typically to the back teeth. The orthodontist incrementally tightens the wire against its anchors over time, encouraging tooth movement in response to the pressure. Clear aligners are a series of removable trays worn in succession that gradually accomplish the same outcome.
Watch out for the rebound. That nice, straight smile you've gained through orthodontics might not stay that way. That's because the same mechanism for tooth movement could cause the teeth to move back to their former positions, especially right after treatment. To avoid this outcome, patients need to wear a retainer, an appliance that holds or "retains" the teeth in their new positions. Depending on their individual situations and age, patients may have to wear a retainer for a few months, years or from then on.

Your teen is about to embark on an orthodontic journey to a straighter, more attractive smile. But although you're excited about the outcome, you both may be steeling yourselves for a few years of "life with braces."
But maybe not—your teen may be able to take advantage of a different kind of corrective appliance: clear aligners. This 21st Century teeth movement method has a number of advantages over braces. For teens, though, there's one big one that could have a huge impact on their social life—clear aligners are nearly invisible to other people.
Clear aligners consist of a series of clear, removable, computer-generated trays based on photographs, models and x-rays of an individual patient's teeth and bite. Each of the trays is slightly different from the previous one in the series, and by wearing each one for about two weeks before moving on to the next, the aligners gradually move the teeth to the desired new positions.
Besides reducing embarrassment often associated with wearing metal braces, clear aligners have other benefits. Unlike braces, they can be removed for eating, easier oral hygiene or for rare special occasions (although for best effectiveness, they should be worn for 20 to 22 hours each day). Recent developments like added elements that help target certain teeth for movement or "power ridges" for more controlled and efficient force have increased the range of bite problems they can be used to correct.
While this means clear aligners can be used for many bite problems, in some severe cases braces and other orthodontic treatments might still be necessary. And because they're not fixed like braces (only the orthodontist can remove them) the patient must have the maturity and self-discipline to wear them consistently.
Your teen will need to undergo a thorough orthodontic examination to see if clear aligners are a viable option for them. If so, it could make the next few treatment years less stressful for both of you.

Have you heard about interceptive orthodontics? This type of early intervention could benefit perhaps 10â??20% of children who need orthodontic treatment, making a positive impact on tooth and jaw development, facial symmetry, and overall self esteem. In case you’re not familiar with it, here are the answers to some common questions about interceptive orthodontic treatment.
Q: What’s the difference between interceptive orthodontics and regular orthodontics?
A: Standard orthodontic treatment typically involves moving teeth into better positions (usually with braces or aligners), and can be done at any age. Interceptive orthodontics uses a variety of techniques to influence the growth and development of teeth and jaws, with the aim of improving their function and appearance. Because it works with the body’s natural growth processes, interceptive treatment is most effective before the onset of puberty (around age 10-14), when growth begins to stop. It is generally not appropriate for adults.
Q: What are the advantages of early treatment with interceptive orthodontics?
A: When it’s done at the right time, interceptive treatment offers results that would be difficult or impossible to achieve at an older age without using more complex or invasive methods — for example, tooth extraction or jaw surgery. That’s why the American Association of Orthodontists, among other professional organizations, recommends that all kids have their first orthodontic screening at age 7.
Q: What are some common issues that can be treated with interceptive orthodontics?
A: One is crowding, where there is not enough room in the jaw to accommodate all the permanent teeth with proper spacing in between. A palatal expander can be used to create more room in the jaw and avoid the need for tooth extraction. Another is a situation where the top and bottom jaws don’t develop at the same rate, resulting in a serious malocclusion (bad bite). A number of special appliances may be used to promote or restrict jaw growth, which can help resolve these problems.
Q: How long does interceptive orthodontic treatment take?
A: Depending on what’s needed, a child might wear a device like a palatal expander or another type of appliance for 6-12 months, followed by a retainer for a period of time. Or, a space maintainer may be left in place for a period of months to hold a place for a permanent tooth to erupt (emerge from the gums). Interceptive treatment ends when a child’s jaw stops growing.
Q: Will braces still be needed after interceptive treatment?
A: Often, but not always, the answer is yes. However, interceptive treatment may shorten the period of time where braces need to be worn, and can help prevent many problems later on.
