“Orthodontic treatment” and “braces” almost seem like synonymous terms. But while braces certainly are orthodontic, it isn't the only tool in an orthodontist's toolkit.
A good example is a device is known as a Herbst appliance. It's used in situations where the upper jaw is outpacing the growth and development of the lower jaw during childhood. If not corrected, this could cause the top teeth to protrude abnormally beyond the lower teeth.
The Herbst appliance gently and gradually coaxes the lower jaw to grow in a more forward direction, thus “catching up” with the upper jaw. The top part of the device consists of two metal tubes hinged to small elastic bands, which are cemented to the cheek side of the upper back teeth (molars), one on either side of the jaw.
Two smaller tubes are attached in like fashion to the lower teeth, and then inserted into the larger tubes. As the lower jaw moves, the smaller tubes move within the larger to create pressure that gently pushes the jaw forward. Over time, this can sync the growth progress of both the upper and lower jaws, and reduce the chances of a poor bite.
For best results, a Herbst appliance is usually placed to coincide with a child's most rapid period of jaw growth, usually between 11 and 14. They could be placed as early as 8 or 9, however, in situations where the front teeth are already protruding well beyond the lips. In any event, the goal is to positively influence the growth of the lower jaw to alleviate or at least minimize the need for future orthodontic treatment.
As a fixed device, there's no need for a child or parent to tend to it as with other methods, like orthodontic headwear worn in conjunction with braces. A Herbst appliance can, however, alter the normal sensations associated with eating, swallowing and speaking, which may take a little adjustment time for the child. Wearers will also need to be extra vigilant with daily brushing and flossing because of a higher risk of tooth decay.
These, though, are minor inconveniences compared with the benefit of improved bite development. As such, a Herbst appliance could be a positive investment in your child's dental future.

If your child has seen the dentist regularly, and brushed and flossed daily, there's a good chance they've avoided advanced tooth decay. But another problem might already be growing right under your nose—a poor dental bite (malocclusion).
A dental bite refers to the way the upper and lower teeth fit together. In a normal bite the teeth are in straight alignment, and the upper teeth slightly extend in front of and over the lower when the jaws are shut. But permanent teeth erupting out of position or a jaw developing abnormally can set the stage for a malocclusion.
Although the full effects of a malocclusion may not manifest until later, there may be signs of its development as early as age 6. If so, it may be possible to identify a budding bite problem and “intercept” it before it goes too far, correcting it or reducing its severity.
Here are 6 signs your school-age child could be developing a malocclusion.
Excessive spacing. If the spacing between teeth seems too wide, it could mean the size of your child's teeth are out of proportion with their jaw.
Underbite. Rather than the normal upper front teeth covering the lower, the lower teeth extend out and over the upper teeth.
Open bite. There's a space or gap between the upper and lower teeth even when the jaws are shut.
Crowding. Due to a lack of space on the jaw, incoming teeth don't have enough room to erupt and may come in misaligned or “crooked.”
Crossbites. Some of the lower teeth, either in front or back of the jaw, overlap the upper teeth, while the rest of the upper teeth overlap normally.
Protrusion or retrusion. This occurs if the upper front teeth or jaw appear too far forward (protrusion) or the lower teeth or jaw are positioned too far back (retrusion).
Besides watching out for the preceding signs yourself, it's also a good idea to have your child undergo a comprehensive bite evaluation with an orthodontist around age 6. If that does reveal something amiss with their bite, intervention now could correct or lessen the problem and future treatment efforts later.
If you're into social media, you might have run across the idea that there's nothing to straightening your teeth. According to some SM influencers, you can even do it yourself with a few rubber bands. But the truth is, the mechanics of moving teeth are much more complex—and taking orthodontics into your own hands can cause extensive dental damage.
In reality, all bite problems (malocclusions) require the advanced knowledge and expertise of an orthodontist to correct them safely and effectively. Some, in fact, may require other devices along with braces or clear aligners to achieve the desired outcome for a particular malocclusion.
Here are a few of those additional tools an orthodontist may use and why they may be needed.
Headgear. Some malocclusions result not just from misaligned teeth, but problems with jaw or facial structure development. To accommodate additional factors like this, an orthodontist may include headgear during treatment, usually a strap running around the back of a patient's head or neck and attached in the front to brackets bonded to the teeth (usually the molars). Wearing this headgear for several hours a day can improve jaw and facial development.
Elastics. Unlike basic rubber bands DIYers might use to move their teeth (often with damaging results), elastics are specialized bands designed for targeted tooth movement. They're needed for bite problems that require moving some teeth and not moving others. As such, elastics can be applied in conjunction with braces to perform either intended task—move or prevent movement for specific teeth.
Anchorage. One of the tools often used with elastics for targeted tooth movement are temporary anchorage devices (TADs). These are typically tiny screws imbedded into the jawbone a short distance from fixed braces. An elastic band connected to the braces at a specific point is then attached to the TAD, which serves as an anchor point for the elastic.
These and other devices can help orthodontists achieve a successful correction for certain individual bite problems. And unlike the DIY methods touted on the Internet, these additional tools help them do it safely.

Approximately 4 million tweens and teens are currently undergoing orthodontic treatment for a poor bite (malocclusion) that can cost their families thousands of dollars in braces or clear aligners. But treatment doesn't always have to follow this track: Found early, many malocclusions can be corrected or minimized before they fully develop.
Known as interceptive orthodontics, this particular approach to bite correction often begins as early as 6-10 years of age. Rather than move existing teeth, interceptive orthodontics focuses instead on redirecting jaw growth and intervening in other situations that can cause malocclusions.
For example, a child's upper jaw may not be growing wide enough to accommodate all incoming permanent teeth, crowding later arrivals out of their proper positions. But taking advantage of a gap during early childhood that runs through the center of the palate (roof of the mouth), orthodontists can increase jaw width with a device called a palatal expander.
The expander fits up against the palate with “legs” that extend and make contact with the inside of the teeth. With gradually applied pressure, the expander widens the central gap and the body naturally fills it with new bone cells. The bone accumulation causes the jaws to widen and create more room for incoming teeth.
Another way a malocclusion can develop involves the primary or “baby” teeth. As one of their purposes, primary teeth serve as placeholders for the future permanent teeth forming in the gums. But if they're lost prematurely, adjacent teeth can drift into the vacant space and crowd out incoming teeth.
Dentists prevent this with a space maintainer, a thin metal loop attached to the adjoining teeth that puts pressure on them to prevent them from entering the space. This spacer is removed when the permanent tooth is ready to erupt.
These and other interceptive methods are often effective in minimizing the formation of malocclusions. But it's often best to use them early: Palatal expansion, for example, is best undertaken before the central gap fuses in early puberty, and space maintainers before the permanent tooth erupts.
That's why we recommend that children undergo an orthodontic evaluation around age 6 to assess their early bite development. If a malocclusion looks likely, early intervention could prevent it and reduce future treatment costs.

The monarchs of the world experience the same health issues as their subjects—but they often tend to be hush-hush about it. Recently, though, the normally reticent Queen Elizabeth II let some young dental patients in on a lesser known fact about Her Majesty's teeth.
While touring a new dental hospital, the queen told some children being fitted for braces that she too “had wires” once upon a time. She also said, “I think it's worth it in the end.”
The queen isn't the only member of the House of Windsor to need help with a poor bite. Both Princes William and Harry have worn braces, as have other members of the royal family. A propensity for overbites, underbites and other malocclusions (poor bites) can indeed pass down through families, whether of noble or common lineage.
Fortunately, there are many ways to correct congenital malocclusions, depending on their type and severity. Here are 3 of them.
Braces and clear aligners. Braces are the tried and true way to straighten misaligned teeth, while the clear aligner method—removable plastic mouth trays—is the relative “new kid on the block.” Braces are indeed effective for a wide range of malocclusions, but their wires and brackets make it difficult to brush and floss, and they're not particularly attractive. Clear aligners solve both of these issues, though they may not handle more complex malocclusions as well as braces.
Palatal expanders. When the upper jaw develops too narrowly, a malocclusion may result from teeth crowding into too small a space. But before the upper jaw bones fuse together in late childhood, orthodontists can fit a device called a palatal expander inside the upper teeth, which exerts gentle outward pressure on the teeth. This encourages more bone growth in the center to widen the jaw and help prevent a difficult malocclusion from forming.
Specialized braces for impacted teeth. An impacted tooth, which remains partially or completely hidden in the gums, can impede dental health, function and appearance. But we may be able to coax some impacted teeth like the front canines into full eruption. This requires a special orthodontic technique in which a bracket is surgically attached to the impacted tooth's crown. A chain connected to the bracket is then looped over other orthodontic hardware to gradually pull the tooth down where it should be.
Although some techniques like palatal expanders are best undertaken in early dental development, people of any age and reasonably good health can have a problem bite corrected with other methods. If you are among those who benefit from orthodontics, you'll have something in common with the Sovereign of the British Isles: a healthy, attractive and straighter smile.
