The big day finally arrives when your braces come off. And there it is—your new, beautiful, straight smile! But on closer inspection you notice something else: tiny white spots on your teeth.
Those pale, chalky spots are called white spot lesions (WSLs). They occur when acid has contacted the tooth enamel for too long, dissolving essential minerals like calcium in those particular areas. The occurrences of WSLs during and after braces highlights a major challenge during orthodontic treatment—keeping your teeth clean.
Braces' wires and brackets tend to get in the way of brushing and flossing, making it easier to miss plaque—the bacterial film that produces acid—on tooth areas around the hardware. Those missed areas could in time lead to WSLs.
The main objective with WSLs is prevent them from occurring during braces wear as much as possible. To do this, you'll need to increase your time and effort brushing and flossing, especially around orthodontic hardware. You can make it easier, though, by using a few tools that often work better than regular toothbrushes and floss like interproximal toothbrushes, power brushes, floss threaders or water flossers.
You can also help lower your mouth's acidity by avoiding or limiting acidic foods and beverages, including juices, sodas, sports and energy drinks. And, by all means, keep up your regular dental cleaning schedule with your general dentist.
Should WSLs develop while you're wearing braces, don't panic. It's possible they'll diminish on their own, or at least not worsen. We can also foster re-mineralization of the enamel with applied fluoride, short bursts of laser light or a procedure called microabrasion that restores damaged areas below the enamel surface.
For more resistant WSLs, we can also inject a liquid tooth-colored resin into them that when hardened by a curing light can make those areas look translucent like normal enamel. We can also use other cosmetic solutions like bonding or veneers to improve your teeth's appearance.
Like other dental problems, dealing with a WSL is usually more successful if caught and treated early. So, check your teeth often while wearing braces, and if you notice anything unusual don't hesitate to call your dentist.

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.

“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.
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.
