When your braces finally come off, you’ll hopefully be astounded by what you see –once-crooked teeth replaced by a more attractive smile. But you might also see something you didn’t expect: noticeable white spots on some of your teeth.
These spots called white spot lesions (WSLs) appear lighter than the surrounding tooth enamel due to mineral loss just beneath the surface. This happens because bacterial or food acids have contacted the enamel surface for too long and dissolved the underlying calcium and other minerals. This results in a small discolored and chalky-like area in the enamel.
WSLs are common during orthodontics because wires and brackets create hard to reach places for brushing and flossing, which can accumulate bacterial plaque. The bacteria produce acid, which weakens the enamel at these places. The tiny white spots that result are more than just unattractive—they can become entry points into the tooth for decay. That’s why they should be dealt with as soon as possible—and preferably before they’re created.
To that end, you’ll need to do as thorough a job as possible brushing and flossing while undergoing orthodontic treatment. To improve your thoroughness try using an interproximal toothbrush that can maneuver more closely around braces hardware than a regular brush. You can also improve your flossing with a floss threader or a water flosser, a device that sprays pressurized water to loosen and flush away plaque.
If you do develop WSLs, there are some things we can do to treat them. We can attempt to re-mineralize the affected enamel with the help of topical fluoride (either pastes or gels for home use or with an office application) or a re-mineralizing agent. We can also use techniques like microabrasion, which restores damaged areas beneath the surface, or inject a liquid, tooth-colored resin beneath the WSL’s surface to improve appearance and protect against decay.
If while wearing braces you do notice any white spots or other tooth discoloration let your dentist or orthodontist know right away. The sooner your dental providers can begin dealing with potential WSLs the better your chances for a healthy and beautiful outcome after braces.

Anyone at any age, including older children and teenagers, can lose or be born missing a permanent tooth. And while those missing teeth can be restored, replacing them in patients who haven’t yet reached adulthood can be tricky.
That’s because their dental and facial development isn’t finished. This is especially problematic for dental implants because as the jaws continue to grow, a “non-growing” implant could eventually appear out of alignment with the surrounding natural teeth. That’s why it’s often better to install a temporary restoration until the jaws fully mature in early adulthood. Two great choices are a removable partial denture (RPD) or a bonded (“Maryland”) bridge.
While “dentures” and “teens” don’t seem to go together, an RPD in fact can effectively restore a teen’s lost dental function and appearance. Of the various types of RPDs the one usually recommended for teens has a hard acrylic base colored to resemble the gums, to which we attach prosthetic (“false”) teeth at their appropriate positions on the jaw.
Besides effectiveness, RPDs are easy to clean and maintain. On the downside, though, an RPD can break and—as a removable appliance—become lost. They can also lose their fit due to changes in jaw structure.
The bonded bridge is similar to a traditional fixed bridge. But there’s one big difference: traditional bridges crown the natural teeth on either side of the missing teeth to secure them in place. The supporting teeth must be significantly (and permanently) altered to accommodate the life-like crowns on either end of the bridge.
Instead, a bonded bridge affixes “wings” of dental material extending from the back of the bridge to the back of the natural teeth on either side. While not quite as strong as a regular bridge, the bonded bridge avoids altering any natural teeth.
While a fixed bridge conveniently stays in place, they’re more difficult than an RPD to keep clean. And while less prone to breakage, they aren’t entirely immune to certain stresses from biting and chewing especially in the presence of some poor bites (how the upper and lower teeth come together).
Choosing between the two restorations will depend on these and other factors. But either choice can serve your teen well until they’re able to permanently replace their missing teeth.
So you’re tearing up the dance floor at a friend’s wedding, when all of a sudden one of your pals lands an accidental blow to your face — chipping out part of your front tooth, which lands right on the floorboards! Meanwhile, your wife (who is nine months pregnant) is expecting you home in one piece, and you may have to pose for a picture with the baby at any moment. What will you do now?
Take a tip from Prince William of England. According to the British tabloid The Daily Mail, the future king found himself in just this situation in 2013. His solution: Pay a late-night visit to a discreet dentist and get it fixed up — then stay calm and carry on!
Actually, dental emergencies of this type are fairly common. While nobody at the palace is saying exactly what was done for the damaged tooth, there are several ways to remedy this dental dilemma.
If the broken part is relatively small, chances are the tooth can be repaired by bonding with composite resin. In this process, tooth-colored material is used to replace the damaged, chipped or discolored region. Composite resin is a super-strong mixture of plastic and glass components that not only looks quite natural, but bonds tightly to the natural tooth structure. Best of all, the bonding procedure can usually be accomplished in just one visit to the dental office — there’s no lab work involved. And while it won’t last forever, a bonded tooth should hold up well for at least several years with only routine dental care.
If a larger piece of the tooth is broken off and recovered, it is sometimes possible to reattach it via bonding. However, for more serious damage — like a severely fractured or broken tooth — a crown (cap) may be required. In this restoration process, the entire visible portion of the tooth may be capped with a sturdy covering made of porcelain, gold, or porcelain fused to a gold metal alloy.
A crown restoration is more involved than bonding. It begins with making a 3-D model of the damaged tooth and its neighbors. From this model, a tooth replica will be fabricated by a skilled technician; it will match the existing teeth closely and fit into the bite perfectly. Next, the damaged tooth will be prepared, and the crown will be securely attached to it. Crown restorations are strong, lifelike and permanent.
Was the future king “crowned” — or was his tooth bonded? We may never know for sure. But it’s good to know that even if we’ll never be royals, we still have several options for fixing a damaged tooth.
