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.

At any given time some 4 million teens and pre-teens are wearing braces or other orthodontic appliances to correct a malocclusion (poor bite). While most cases are straightforward, some have difficulties that increase treatment time and cost.
But what if you could reduce some of these difficulties before they fully develop? We often can through interceptive orthodontics.
This growing concept involves early orthodontic treatment around 6 to 10 years of age with the goal of guiding the development of a child’s jaws and other mouth structures in the right direction. These early years are often the only time of life when many of these treatments will work.
For example, widening the roof of the mouth (the palate) in an abnormally narrow upper jaw takes advantage of a gap in the bone in the center of the palate that doesn’t fuse until later in adolescence. A device called a palatal expander exerts outward pressure on the back teeth to influence the jawbone to grow out. New bone fills in the gap to permanently expand the jaw.
In cases with a developing overbite (the upper front teeth extending too far over the lower teeth when closed), we can install a hinged device called a Herbst appliance to the jaws in the back of the mouth. The hinge mechanism coaxes the lower jaw to develop further forward, which may help avoid more extensive and expensive jaw surgery later.
Interceptive treatments can also be fairly simple in design like a space retainer, but still have a tremendous impact on bite development. A space maintainer is often used when a primary (“baby”) tooth is lost prematurely, which allows other teeth to drift into the empty space and crowd out the incoming permanent tooth. The wire loop device is placed within the open space to prevent drift and preserve the space for the permanent tooth.
To take advantage of these treatments, it’s best to have your child’s bite evaluated early. Professional organizations like the American Association of Orthodontists (AAO) recommend a screening by age 7. While it may reveal no abnormalities at all, it could also provide the first signs of an emerging problem. With interceptive orthodontics we may be able to correct them now or make them less of a problem for the future.

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.

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.

In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.
When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”
Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.
There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.
By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.
So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.
