Advances in technology often lead to greater choices for things like automobiles or smartphones. In recent decades, advances in orthodontics have given families another choice besides braces for straightening teeth: clear aligners.
Clear aligners are a series of computer-generated mouth trays of clear plastic that are custom made for an individual patient's teeth. Like braces, these trays worn in the mouth put pressure on the teeth to move in a desired direction. Patients wear an individual tray for about two weeks and then change it out for the next tray in the series. Each subsequent tray is designed to pick up where the former tray left off in the progress of tooth movement.
Although treatment takes about as along as braces, clear aligners have some distinct advantages. First and foremost, their clear plastic construction makes them nearly invisible to outside observers. This makes them ideal for appearance-conscious teens (or adults) who may be embarrassed by the look of metallic braces.
And unlike their fixed counterpart, clear aligners can be removed by the wearer for meals, hygiene and the rare special occasion. As a result, patients with aligners aren't as restricted with food items and have an easier time keeping their teeth clean and avoiding dental disease than braces wearers.
But although definitely a benefit, removability can be potentially problematic depending on the maturity level of the patient. To be effective, an aligner tray must remain in the mouth for the majority of the time—too much time out negates the effect. Patients, then, must be responsible with wearing aligners as directed.
Clear aligners may also not work for treating difficult bites, especially those that require targeted movement (or non-movement) of select teeth. In those cases, braces may be the necessary treatment. But this situation has changed in recent years with the development of new devices and techniques that increase the range of bite problems clear aligners can treat.
Depending then on the bite problem and a patient's level of personal responsibility, clear aligners can be a viable orthodontic choice. And just like braces, they too can improve both dental function and appearance.

During election season, you'll often hear celebrities encouraging you to vote. But this year, Kaia Gerber, an up-and-coming model following the career path of her mother Cindy Crawford, made a unique election appeal—while getting her wisdom teeth removed.
With ice packs secured to her jaw, Gerber posted a selfie to social media right after her surgery. The caption read, “We don't need wisdom teeth to vote wisely.”
That's great advice—electing our leaders is one of the most important choices we make as a society. But Gerber's post also highlights another decision that bears careful consideration, whether or not to have your wisdom teeth removed.
Found in the very back of the mouth, wisdom teeth (or “third molars”) are usually the last of the permanent teeth to erupt between ages 17 and 25. But although their name may be a salute to coming of age, in reality wisdom teeth can be a pain. Because they're usually last to the party, they're often erupting in a jaw already crowded with teeth. Such a situation can be a recipe for numerous dental problems.
Crowded wisdom teeth may not erupt properly and remain totally or partially hidden within the gums (impaction). As such, they can impinge on and damage the roots of neighboring teeth, and can make overall hygiene more difficult, increasing the risk of dental disease. They can also help pressure other teeth out of position, resulting in an abnormal bite.
Because of this potential for problems, it's been a common practice in dentistry to remove wisdom teeth preemptively before any problems arise. As a result, wisdom teeth extractions are the top oral surgical procedure performed, with around 10 million of them removed every year.
But that practice is beginning to wane, as many dentists are now adopting more of a “wait and see” approach. If the wisdom teeth show signs of problems—impaction, tooth decay, gum disease or bite influence—removal is usually recommended. If not, though, the wisdom teeth are closely monitored during adolescence and early adulthood. If no problems develop, they may be left intact.
This approach works best if you maintain regular dental cleanings and checkups. During these visits, we'll be able to consistently evaluate the overall health of your mouth, particularly in relation to your wisdom teeth.
Just as getting information on candidates helps you decide your vote, this approach of watchful waiting can help us recommend the best course for your wisdom teeth. Whether you vote your wisdom teeth “in” or “out,” you'll be able to do it wisely.
At what age should you begin treating a poor bite? Many might say with braces around late childhood or early adolescence. But some bite problems could be addressed earlier—with the possibility of avoiding future orthodontic treatment.
A crossbite is a good example. In a normal bite, all of the upper teeth slightly cover the lower when the jaws are shut. But a crossbite occurs when some of the lower teeth, particularly in back, overlap the upper teeth. This situation often happens when the upper jaw develops too narrowly.
But one feature of a child's mouth structure provides an opportunity to intervene and alter jaw development. During a child's early years, the palate (roof of the mouth) consists of two bones next to each other with an open seam running between them. This seam, which runs through the center of the mouth from front to back, will fuse during puberty to form one continuous palatal bone.
An orthodontist can take advantage of this separation if the jaw isn't growing wide enough with a unique device called a palatal expander. This particular oral appliance consists of four, thin metal legs connected to a central mechanism. The orthodontist places the expander against the palate and then uses the mechanism to extend the legs firmly against the back of the teeth on both sides of the jaw.
The outward pressure exerted by the legs also widens the seam between the two palatal bones. The body will respond to this by adding new bone to the existing palatal bones to fill in the widened gap. At regular intervals, the patient or a caregiver will operate the mechanism with a key that will continue to widen the gap between the bones, causing more expansion of the palatal bones until the jaw has grown to a normal width.
The palatal expander is most effective when it's applied early enough to develop more bone before the seam closes. That's why it's important for children to undergo bite evaluation with an orthodontist around age 6. If it appears a bite problem is developing, early interventions like a palatal expander could slow or stop it before it gets worse.
