While braces are often the stars for straightening smiles, they're not the only cast members in an orthodontic production. Orthodontists occasionally turn to other appliances if the bite problem is challenging. Whatever the tool, though, they usually have something in common—they use the principle of anchorage.
To understand anchorage, let's first consider the classic kid's game Tug of War. With teams on either end of a rope, the object is to pull the opposing team across the center line before they pull you. To maximize your pulling force, the player at the back of your rope, usually your stoutest member, holds steady or "anchors" the rest of the team.
Like a Tug of War team, braces exert force against the teeth. This stimulates the supporting periodontal ligament to remodel itself and allow the teeth to move. The braces use the teeth they are attached to as anchors, which in a lot of cases are the back teeth. By attaching a thin wire to the brackets or braces on the teeth, the orthodontist includes all the teeth on the arch, from one end to the other. Anchored in place, the wire can maintain a constant pressure against the teeth to move them.
But not all bite situations are this straightforward. Sometimes an orthodontist needs to influence jaw growth in addition to teeth movement. For this purpose, they often use orthodontic headgear, which runs around the back of the head or neck and attaches to orthodontic brackets on the teeth. It still involves an anchor but in this case it's the patient's own skull.
In some situations, an orthodontist may feel he or she needs more anchorage as the teeth alone may not be enough. For this, they might establish a separate or additional anchor point using a temporary anchorage device (TAD). A TAD resembles a tiny screw that's inserted into the jawbone near the tooth intended for movement. The orthodontist can then attach the TAD to braces hardware using some form of elastics. After treatment, they remove the TAD.
These are just a couple examples of specialized tools an orthodontist can use for bite correction. Thanks to them and similar devices, even the most complex bite problem can be overcome to create a healthier and more attractive smile.

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.

Moving teeth to better positions through orthodontics not only improves dental function and health, it can vastly improve your appearance. But to achieve a result that continues to be attractive as you age requires thorough planning and forethought.
That’s because your body continues to change all during life. While the most accelerated growth happens in childhood and adolescence, even older adults continue to change, especially in their facial features. A good deal of research has helped identify and catalog these changes, which orthodontists now incorporate into their corrective treatments for poor bites (malocclusions).
For example, the lips grow until they reach their maximum thickness in girls usually around age 14 and boys age 16. But researchers have also found lip thickness gradually diminishes for most people beginning in their late teens until about age 80. In other words, the appearance of your lips in your elderly years will be vastly different than in your teens. The same holds true for other facial features: our facial profile flattens as the nose becomes longer and more pronounced while the lower part of the face shortens.
Using this knowledge of the effects of aging on the face, orthodontists now attempt to anticipate “where” the facial features will be decades down the road. This projection can help them design a treatment plan that takes advantage of these projected changes.
For example, orthodontists may begin treatment before a patient’s teenage years with techniques that serve to guide jaw growth. Keeping that development on track will help if or when braces may be needed a few years later. Guiding jaw growth will help shorten the distance of where a patient is in their orofacial development and where they should be later in life with normal development.
Orthodontists aren’t predictors of the future. But armed with an understanding of the aging process, they can help patients head in the right direction to produce a smile and facial appearance that will endure well into later life.

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.

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.
