Malocclusions (bad bites) may cause more than an appearance problem — with teeth and jaws not working together properly, you’re at higher risk for dental disease or accelerated tooth wear. Fortunately, most malocclusions can be corrected through orthodontics, a specialty for moving teeth to better functioning and more attractive positions.
If you’re considering orthodontic treatment for a malocclusion, here are the basics on 3 of the most common orthodontic appliances used for straightening misaligned teeth.
Metal Braces. These appliances have a proven track record for correcting most forms of malocclusion. Braces consist of metal brackets bonded to the front teeth and an anchor band to the back teeth. A thin metal wire passes through the brackets to attach to the bands in the back. Gradually increased tension in the wire incrementally moves the teeth to the desired position.
Clear Bracket Braces. While metal braces do an effective job of tooth movement, they leave less to be desired in appearance. Made of polymer material rather than metal, clear bracket braces offer a more appealing look. But while they’re similar in construction to the metal version, they’re more susceptible to breakage. Wearers must be extra cautious and avoid hard foods or extreme physical sports contact.
Clear Aligners. The previous appliances are fixed and can’t be removed by the wearer. Clear aligners take a different approach with removable plastic trays that fit snugly over the dental arch. A series of trays are computer generated to carefully match the patient’s mouth structure, each incrementally smaller than the previous one in the series. After wearing the first tray for two or three weeks, the wearer changes to the next (and slightly smaller) tray in the series, repeating the process until all the trays have been worn. Of the three options, the clear aligners offer the best appearance; however, they’re best suited for cases that don’t require complex movements.
We can advise you which option is best for you after a complete evaluation, factoring in age, lifestyle and the complexity of your malocclusion. Regardless of the choice, the aim is the same — achieving a healthier mouth, better function and a more attractive smile.

The braces are finally off! But to keep your new, straighter smile you'll need to wear a retainer for some time. That's because the same structural mechanism used to move your teeth could undo what we've just accomplished.
That mechanism resides in an elastic tissue called the periodontal ligament that lies between the teeth and the bone and attaches to both with tiny fibers. While the ligament holds the teeth securely in place, it also allows for slight movement in response to bite changes. Braces "pull" the teeth in the desired new direction, and the ligament responds.
But with that pressure gone after the braces' removal, a kind of "muscle memory" can set in that moves the teeth back towards their original positions. A retainer, a dental appliance worn on the teeth, exerts just enough pressure to "retain" or keep the teeth from regressing.
Retainers are effective, but the most common type has a feature that poses potential problems: it can be removed by the wearer. Because of this, less disciplined patients might be tempted not to wear their retainer as directed. There's also a higher risk of losing one and incurring additional cost to replace it.
But there is another type, the bonded retainer, which stays permanently in the mouth until removed by an orthodontist. It's composed of a thin piece of metal that's firmly attached to the back of the teeth with dental composite material. Not only does a bonded retainer solve the problems mentioned before, it also can't be seen from the outside like a removable retainer.
A bonded retainer does have one disadvantage: because it can't be removed, it can obstruct the teeth during brushing and flossing and require more effort. You won't have as much difficulty with a removable retainer keeping teeth and gums clean. You can overcome this disadvantage, though, with specialized tools like a water flosser or a floss threader to make hygiene easier.
To choose which type of retainer is best for you or your family member, have a talk with your orthodontist. And if you choose a bonded retainer and later have it removed, be sure to switch immediately to a removable one if your orthodontist advises. With either retainer, you'll be able to preserve that hard-earned smile for years to come.

About one-quarter of people have teeth that never developed. While most of these congenitally missing teeth are wisdom teeth, they can also include premolars or lateral incisors (the teeth right next to the two front teeth, the central incisors).
Missing teeth can have an adverse effect on smile appearance. But that’s not all: because each type of tooth performs a specific function, one or more missing teeth can lead to bite problems and disruption of dental function. In the case of missing lateral incisors, the canines (eye teeth) normally positioned beside and toward the back of the mouth from them may begin to drift into the empty space and grow next to the central incisors. This can result in greater difficulty chewing and a smile that “doesn’t look right.”
To correct this situation, we must often first attempt to orthodontically move any out of place teeth to their normal positions. This re-establishes the space needed for the missing teeth to be replaced, which we can then restore with prosthetic (artificial) teeth. If the permanent restoration of choice involves dental implants, we’ll usually need to wait until the completion of jaw development around early adulthood. In the mean time, we can use a retainer appliance to hold the teeth in their new positions with prosthetic teeth attached to fill the empty space for a better smile appearance in the interim.
The real issue is timing—beginning orthodontic treatment when appropriate to a person’s oral development, as well as completing the implant restoration when the mouth has matured sufficiently. There are other considerations such as bone volume, which may have diminished due to the missing teeth. At some point we may need to consider grafting to build up the bone sufficiently to support dental implants.
This all may entail a team approach by various specialties like orthodontics, periodontics and implantology. Working together and coordinating within a timely schedule, a mouth and smile marred by undeveloped teeth can be transformed.
