“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.

In any given year, 4 million tweens and teens are in the process of having their teeth straightened with braces or clear aligners. It's so common we tend to consider orthodontic treatment for young people as a rite of passage into adulthood.
But it doesn't necessarily have to be that way—it might be possible to stop or at least minimize a poor bite before it fully develops. That's the goal of interceptive orthodontics—treatments that head off or “intercept” a bite problem early.
The goal isn't necessarily to reposition misaligned teeth, but to correct a problem that can lead to misalignment. Here are some examples.
A narrow jaw. A narrowly developing jaw can crowd incoming teeth out of their normal positions. For the upper jaw, though, we can take advantage of a temporary separation in the bones in the roof of the mouth (palate) with a device called a palatal expander. Placed against the palate, the expander exerts outward pressure on the teeth and jaw to widen this separation. The body fills in the gap with bone to gradually widen the jaw.
Abnormal jaw alignment. It's possible for a jaw to develop abnormally during childhood so that it extends too far beyond the other. Using a hinged device called a Herbst appliance, it's possible to interrupt this abnormal growth pattern and influence the bones and muscles of the jaw to grow in a different way.
Missing primary teeth. An important role for a primary (baby) tooth is to hold a place for the future permanent tooth. But if the primary tooth is lost too soon, other teeth can drift into the space and crowd out the intended permanent tooth. To prevent this, we can insert a space maintainer: This simple looped metal device prevents teeth from drifting and preserves the space for the permanent tooth.
Although these and other interceptive treatments are effective, some like the palatal expander do their best work within a limited age frame. To take advantage of interceptive orthodontics in a timely manner, parents should seek a bite evaluation for their child from an orthodontist around age 6. The earlier we detect a growing bite problem, the greater your chances for successful intervention.

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.
Before we begin correcting a malocclusion (poor dental bite), we need to ask a few questions: How extensive is the malocclusion? How far must we move the teeth to correct it? How might the patient's jaw size impact treatment?
Answering these and other questions help us develop an effective treatment plan. And depending on the answers, we might need to look at other procedures before we install braces—like removing one or more of the teeth.
This isn't a subject to approach lightly: All teeth play an important role in dental function and smile appearance, and ordinarily we want to preserve teeth, not remove them. Sometimes, however, it may be a necessary action to achieve our goal of an improved dental bite.
For example, it might be necessary for correcting a malocclusion caused by severe teeth crowding. This occurs when one or both of the jaws hasn't grown to a sufficient size to accommodate all of the teeth erupting on it. As a result, some of the teeth could come in out of their proper alignment.
If caught early before puberty, we may be able to use other techniques to alleviate crowding, like a device called a palatal expander that influences an upper jaw to widen as it grows. If successful, it could provide later teeth more room to erupt in their proper positions.
But even if additional jaw growth occurs, it may not be enough to avoid a malocclusion or treatment with braces. Alleviating further crowding by removing teeth in little noticed areas could help with subsequent orthodontics.
Removing teeth may also be the answer for other problems like an impacted tooth, in which the tooth has not fully erupted and remains submerged in the gums. It's sometimes possible to use a technique to “pull” the tooth down where it should be; but again, that will still require jaw space that may not be available. The more effective course might be to remove the impacted tooth.
Whether or not tooth extraction will be needed can depend on a thorough orthodontic evaluation and full consideration of all the available options. Even though the ideal situation is to correct a bite with all teeth present and accounted for, it may be for the better good to sacrifice some.

If you've decided to straighten your teeth, you've made a wise choice for both your dental health and your smile. Now you may be facing another decision—which method to use for bite correction.
Not too long ago people had only one choice—traditional braces all the way. But that changed with the introduction of clear aligners, a series of removable plastic trays worn one after the other to realign teeth. In all but a few situations, clear aligners accomplish the same outcome as braces but without the conspicuous appearance and, thanks to their removability, difficulty in brushing and flossing teeth.
And now, a recent innovation in orthodontics could give you a third option—lingual braces. These are braces fixed to the back of teeth adjacent to the tongue (hence the term “lingual”), rather than on the front as with traditional braces. They essentially perform the same action, only instead of “pushing” teeth like traditional braces, they “pull” the teeth to the target positions. Lingual braces may also ease certain disadvantages people find with traditional braces or clear aligners.
If you're into martial arts, for instance, you may encounter blows to the face that increase your injury risk while wearing traditional braces. Likewise, if you're highly social, clear aligners can be a hassle to take out and keep up with if you're frequently eating in public. Lingual braces answer both types of issues: They won't damage your lips or gums in the case of blunt force facial contact; and they remain out of sight, out of mind in social situations.
Before considering lingual braces, though, keep in mind that they may cost 15-35 percent more than traditional braces. They also take time for some people to get used to because of how they feel to the tongue. And, they're not yet as widely available as traditional braces, although the number of orthodontists who have received training in the new method is increasing.
If you'd like to know more about lingual braces and whether they're right for you, speak to your dentist or orthodontist. You may find that this new option for improving your dental health and your smile fits your lifestyle.
