Orthodontics relies on certain mechanics in the mouth to move teeth to better positions. As the specialty has advanced, we've become ever more precise in moving teeth with braces, the “workhorse” of orthodontics, and other specialized appliances and techniques.
But although cooperating effectively with the mouth's natural ability for tooth movement is crucial for success, there's another aspect to consider if that success will be long-term: the growth and development of oral and facial structure. And not just development during childhood and adolescence: indeed, facial structure continues to change throughout a lifetime, including the senior years. Research has shown that although the rate of growth slows over time, it doesn't stop even for someone 80 years or older.
Our emerging understanding in this area has had an important impact on how and when we perform orthodontic treatment. As we develop a treatment strategy for an individual patient we consider not only the immediate outcome of a treatment, but also how it may change their facial appearance in the future. By taking continuing facial growth into consideration, we're more likely to achieve a new smile appearance that remains attractive later in life.
A key factor is to be sure we're initiating treatments at appropriate ages. We may detect developing bite problems as early as age 6, which might prompt preventive treatment at that time to diminish or even eliminate the problem. But it may also be prudent to wait on full-scale orthodontic treatment until late childhood or puberty. Furthermore, some form of orthodontic treatment might need to continue into early adulthood to ensure the most optimal outcome.
By taking a longer view of the treatment process, we're better able to work within the natural growth and development taking place now and in the future. As a result, a person is more likely to enjoy an attractive and youthful appearance even in their later years.

Magician Michael Grandinetti mystifies and astonishes audiences with his sleight of hand and mastery of illusion. But when he initially steps onto the stage, it’s his smile that grabs the attention. “The first thing… that an audience notices is your smile; it’s what really connects you as a person to them,” Michael told an interviewer.
He attributes his audience-pleasing smile to several years of orthodontic treatment as a teenager to straighten misaligned teeth, plus a lifetime of good oral care. “I’m so thankful that I did it,” he said about wearing orthodontic braces. “It was so beneficial. And… looking at the path I’ve chosen, it was life-changing.”
Orthodontics — the dental subspecialty focused on treating malocclusions (literally “bad bites”) — can indeed make life-changing improvements. Properly positioned teeth are integral to the aesthetics of any smile, and a smile that’s pleasing to look at boosts confidence and self-esteem and makes a terrific first impression. Studies have even linked having an attractive smile with greater professional success.
There can also be functional benefits such as improved biting/chewing and speech, and reduced strain on jaw muscles and joints. Additionally, well-aligned teeth are easier to clean and less likely to trap food particles that can lead to decay.
The Science Behind the Magic
There are more options than ever for correcting bites, but all capitalize on the fact that teeth are suspended in individual jawbone sockets by elastic periodontal ligaments that enable them to move. Orthodontic appliances (commonly called braces or clear aligners) place light, controlled forces on teeth in a calculated fashion to move them into their new desired alignment.
The “gold standard” in orthodontic treatment remains the orthodontic band for posterior (back) teeth and the bonded bracket for front teeth. Thin, flexible wires threaded through the brackets create the light forces needed for repositioning. Traditionally the brackets have been made of metal, but for those concerned about the aesthetics, they can also be made out of a clear material. Lingual braces, which are bonded to the back of teeth instead of the front, are another less visible option. The most discrete appliance is the removable clear aligner, which consists of a progression of custom-made clear trays that reposition teeth incrementally.
How’s that for a disappearing act?!

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!
If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.
If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?
As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.
And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!

After months of treatment we’ve removed your braces and your new smile emerges. Upon closer view, however, you notice a number of chalky white spots on your teeth.
These pale areas are white spot lesions (WSLs), the result of mineral breakdown from the long-term contact of acid with the enamel surface. The underlying cause is built-up bacterial plaque due to inadequate oral hygiene, and as such WSLs are the beginning stages of tooth decay.
While anyone can develop WSLs, brace wearers are highly susceptible because of the extra care required to clean around orthodontic hardware. Poor dietary habits such as frequent snacking on sugary or acidic foods and beverages also increase the risk of WSLs.
To reduce the risk of developing this condition, brace wearers must give extra attention and effort to daily oral hygiene, including brushing and flossing. The extra effort required in brushing can be aided by specialized toothbrushes designed to clean around brackets and wires, along with prescription-level fluoride toothpastes for added enamel strength. Floss threaders or a water flosser, a device that uses pulsating water under high pressure, may help you maneuver around hardware to remove plaque between teeth. It's also important to maintain a healthy mouth environment by limiting intake of sugary or acidic snacks and beverages, avoiding tobacco or excessive alcohol or caffeine, and drinking plenty of water to keep your mouth from drying out.
If you’ve already developed lesions, it’s important to stop the decay process before it causes more damage. One way is to assist your body’s natural mechanism for re-mineralizing tooth enamel with fluoride pastes or gels or re-mineralizing agents, or undergoing micro-abrasion to repair a tooth’s surface.
To improve a tooth’s appearance a procedure known as “caries infiltration” involves injecting a liquid tooth-colored resin into the lesion, which is then hardened with a curing light. The spot becomes less noticeable and appears more like normal enamel. For extensive defects, conventional bonding with composite resins or porcelain veneers can be used to cosmetically cover the tooth.
Getting ahead of the problem with effective oral hygiene and good dietary and lifestyle practices will keep WSLs at bay while you undergo orthodontic treatment. If they do develop, however, there are ways to minimize their effect and restore the look of your teeth.
Most of us are quite familiar with what traditional braces look like. But occasionally we see more complex-looking devices being worn by young orthodontic patients: thicker wires that extend outside the mouth, with straps that may go behind the neck or over the chin. What are these devices, and why are they sometimes needed?
In general, orthodontic appliances with external parts braced by the head, neck or chin are referred to as “headgear.” These devices may be used to handle a number of particular orthodontic situations, but they all have one thing in common: They provide the additional anchorage needed to move teeth into better positions.
It may come as a surprise that teeth, which seem so solid, can actually be moved fairly easily over time. This is because teeth are not fixed directly into bone, but are instead held in place by a hammock-like structure called the periodontal ligament. Using a light, controlled force — such as the force of springy wires and elastics in traditional braces — teeth can be moved slowly through the jaw bone, like a stick being pulled through sand.
Of course, to pull a stick through sand, you need a firm anchorage — your legs, for example, bracing against a rock. Most of the time, the back teeth, with their large, multiple roots, provide plenty of support. But sometimes, the back teeth alone aren’t enough to do the job.
If a very large space between teeth is being closed, for example, the back teeth might be pulled forward as the front teeth are pulled back; this could result in poor alignment and bite problems. In other cases, the front teeth may need to be pulled forward instead of back. The back teeth can’t help here; this is a job for headgear.
Some types of headgear have a strap that goes behind the head or neck; they use the entire head as an anchorage. Other types, called “reverse pull” headgear, have a strap that comes over the chin or the forehead; they can pull teeth forward. Headgear can even influence the proper growth of facial structures — that’s why it is usually seen on preteens, whose growth isn’t yet complete.
Headgear is usually worn for 12 hours per day, for a limited period of time. In some cases, rather than headgear, appliances called “temporary anchorage devices” (TADS) may be recommended. These are tiny screws that are implanted into the jawbone in a minimally invasive procedure, and serve a similar function.
While it may not look pretty, orthodontic headgear is capable of moving teeth into their proper positions in a relatively short period of time — and ending up with a great-looking smile is what orthodontics is all about.
