While crooked teeth are usually responsible for a malocclusion (poor bite), the root cause could go deeper: a malformed maxilla, a composite structure composed of the upper jaw and palate. If that’s the case, it will take more than braces to correct the bite.
The maxilla actually begins as two bones that fit together along a center line in the roof of the mouth called the midline suture, running back to front in the mouth. The suture remains open in young children to allow for jaw growth, but eventually fuses during adolescence.
Problems arise, though, when these bones don’t fully develop. This can cause the jaw to become too narrow and lead to crowding among the erupting teeth and a compromised airway that can lead to obstructive sleep apnea. This can create a cross-bite where the upper back teeth bite inside their lower counterparts, the opposite of normal.
We can remedy this by stimulating more bone growth along the midline suture before it fuses, resulting in a wider maxilla. We do this by installing a palatal expander, an appliance that incrementally widens the suture to encourage bone formation in the gap, which over time will widen the jaw.
An expander is a metal device with “legs” extending out on both sides and whose ends fit along the inside of the teeth. A gear mechanism in the center extends the legs to push against the teeth on both sides of the jaw. Each day the patient or caregiver uses a key to give the gear a quarter turn to extend the legs a little more and widen the suture gap. We remove the expander once the jaw widens to the appropriate distance.
A palatal expander is an effective, cost-efficient way to improve a bite caused by a narrow jaw, but only if attempted before the bones fuse. Widening the jaw after fusion requires surgery to separate the bones — a much more involved and expensive process.
To make sure your child is on the right track with their bite be sure to see an orthodontist for an evaluation around age 6. Doing so will make it easier to intervene at the proper time with treatments like a palatal expander, and perhaps correct bite problems before they become more expensive to treat.

While wearing braces is the path to a healthier and more attractive smile, it can be a difficult journey. One of your biggest challenges will be keeping your teeth clean to avoid a higher risk of tooth decay.
Tooth decay starts with dental plaque, a thin film of bacteria and food particles that accumulates on teeth. Daily brushing and flossing clear this accumulation. But the hardware of braces makes it difficult to access all tooth surfaces, and can even become a haven for plaque.
One sign in particular of tooth decay while wearing braces is the appearance of chalk-like spots on the teeth known as white spot lesions (WSLs). WSLs occur because the minerals in the enamel beneath them have begun to break down in response to decay. The spots can eventually cause both structural and cosmetic problems for a tooth.
The best approach to WSLs is to prevent them from developing in the first place. You'll need to be extra vigilant with daily oral hygiene while wearing braces to reduce plaque buildup. To help with the increased difficulty you might consider using a special toothbrush designed to maneuver more closely around orthodontic hardware. You may also find using a water flosser to be a lot easier than flossing thread.
Preventing tooth decay and WSLs also includes what you eat or drink to reduce the effects of enamel de-mineralization. The bacteria that cause decay thrive on sugar, so limit your intake of sweetened foods and beverages. And to avoid excessive demineralization cut back on acidic foods as well.
If despite your best preventive efforts WSLs still form, we can take steps to minimize any damage. For one, we can give your enamel a boost with fluoride applications or other remineralization substances. We can also inject a tooth-colored resin beneath the surface of a WSL that will make it less noticeable.
With any of these and other treatments, though, the sooner we can treat the WSL the better the outcome. Practicing good hygiene and dietary habits, as well as keeping an eye out for any WSL formations, will do the most to protect your new and improved smile.

If you’re about to undergo orthodontic treatment, you’re going to face a challenge keeping your teeth and gums clean wearing braces. That in turn could increase your chances for tooth decay or periodontal (gum) disease, which could diminish your future dental health and disrupt your current orthodontic treatment.
The main hygiene tasks of brushing and flossing are more difficult with braces because of the fixed hardware on the teeth. Your toothbrush or floss can’t always easily maneuver around the wires and brackets, increasing the chances you’ll miss some areas. These neglected areas can then accumulate dental plaque, a thin film of bacteria and food particles that’s most responsible for disease.
But although difficult, effective oral hygiene isn’t impossible. First and foremost, you’ll need to take more time to be thorough with brushing and flossing than you might normally without braces.
Second, there are some specialized hygiene tools to make the job easier. Instead of a regular toothbrush try an interproximal brush. This special brush has a long and thin bristled head (resembling a pipe cleaner) that can maneuver in and around orthodontic hardware much easier than a regular brush.
For flossing, use a floss threader, a device through which you thread floss on one end and then pass the other sharper end between your teeth. Once through, you release the floss from it and floss as usual, repeating the process with the threader for each tooth. Another option is an oral irrigator, a device that emits a pressurized spray of water between teeth to loosen plaque and flush it away. Many orthodontic patients have found this latter option to be quite effective.
Finally, continue seeing your regular dentist for regular appointments in addition to your orthodontist. Besides cleaning those hard to reach areas, your dentist can also provide other preventive measures like topical fluoride for strengthening enamel and prescription mouth rinses that inhibit bacterial growth. You should also see your dentist immediately if you notice signs of disease like spots on the teeth or swollen or bleeding gums.
Keeping your teeth clean while wearing braces is a top priority. Doing so will help ensure your new smile after braces is both an attractive and healthy one.

There are many new and exciting ways now to transform an unattractive smile into one you'll be confident to display. But not all “smile makeover” techniques are new — one in particular has been around for generations: using braces to correct crooked teeth.
Braces have improved the smiles (and also dental health) for millions of people. But as commonplace this orthodontic treatment is, it wouldn't work at all if a natural mechanism for moving teeth didn't already exist. Braces “partner” with this mechanism to move teeth to better positions.
The jawbone doesn't actually hold teeth in place — that's the job of an elastic gum tissue between the teeth and bone called the periodontal ligament. Tiny fibers extending from the ligament attach to the teeth on one side and to the bone on the other. In addition to securing them, the dynamic, moldable nature of the ligament allows teeth to move incrementally in response to forces applied against them.
To us, the teeth feel quite stationary (if they don't, that's a problem!). That's because there's sufficient length of the tooth roots that are surrounded by bone, periodontal ligament and gum tissue. But when pressure is applied against the teeth, the periodontal ligament forms both osteoblasts (bone-forming cells) and osteoclasts (bone-resorbing cells) causing the bone to remodel. This allows the teeth to move to a new position.
Braces take advantage of this in a controlled manner. The orthodontist bonds brackets to the outside face of the teeth through which they pass a thin metal wire. They attach the ends of the wire to the brackets (braces), usually on the back teeth. By using the tension placed in the wire, the orthodontist can control the gradual movement of teeth to achieve proper function and aesthetics. The orthodontist continues to monitor the treatment progress, while making periodic adjustments to the tension.
It takes time, but through this marvelous interplay between nature and dental science you'll gain a more healthy and beautiful smile.

While braces are often the stars for straightening smiles, they're not the only cast members in an orthodontic production. Orthodontists occasionally turn to other appliances if the bite problem is challenging. Whatever the tool, though, they usually have something in common—they use the principle of anchorage.
To understand anchorage, let's first consider the classic kid's game Tug of War. With teams on either end of a rope, the object is to pull the opposing team across the center line before they pull you. To maximize your pulling force, the player at the back of your rope, usually your stoutest member, holds steady or "anchors" the rest of the team.
Like a Tug of War team, braces exert force against the teeth. This stimulates the supporting periodontal ligament to remodel itself and allow the teeth to move. The braces use the teeth they are attached to as anchors, which in a lot of cases are the back teeth. By attaching a thin wire to the brackets or braces on the teeth, the orthodontist includes all the teeth on the arch, from one end to the other. Anchored in place, the wire can maintain a constant pressure against the teeth to move them.
But not all bite situations are this straightforward. Sometimes an orthodontist needs to influence jaw growth in addition to teeth movement. For this purpose, they often use orthodontic headgear, which runs around the back of the head or neck and attaches to orthodontic brackets on the teeth. It still involves an anchor but in this case it's the patient's own skull.
In some situations, an orthodontist may feel he or she needs more anchorage as the teeth alone may not be enough. For this, they might establish a separate or additional anchor point using a temporary anchorage device (TAD). A TAD resembles a tiny screw that's inserted into the jawbone near the tooth intended for movement. The orthodontist can then attach the TAD to braces hardware using some form of elastics. After treatment, they remove the TAD.
These are just a couple examples of specialized tools an orthodontist can use for bite correction. Thanks to them and similar devices, even the most complex bite problem can be overcome to create a healthier and more attractive smile.
