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.

Everyone loves a concert where there's plenty of audience participation… until it starts to get out of hand.Â Recently, the platinum-selling band Fifth Harmony was playing to a packed house in Atlanta when things went awry for vocalist Camila Cabello. Fans were batting around a big plastic ball, and one unfortunate swing sent the ball hurtling toward the stage — and directly into Cabello's face. Pushing the microphone into her mouth, it left the “Worth It” singer with a chipped front tooth.
Ouch! Cabello finished the show nevertheless, and didn't seem too upset. “Atlanta… u wild… love u,” she tweeted later that night. “Gotta get it fixed now tho lol.” Fortunately, dentistry offers a number of ways to make that chipped tooth look as good as new.
A small chip at the edge of the tooth can sometimes be polished with dental instruments to remove the sharp edges. If it's a little bigger, a procedure called dental bonding may be recommended. Here, the missing part is filled in with a mixture of plastic resin and glass fillers, which are then cured (hardened) with a special light. The tooth-colored bonding material provides a tough, lifelike restoration that's hard to tell apart from your natural teeth. While bonding can be performed in just one office visit, the material can stain over time and may eventually need to be replaced.
Porcelain veneers are a more long-lasting solution. These wafer-thin coverings go over the entire front surface of the tooth, and can resolve a number of defects — including chips, discoloration, and even minor size or spacing irregularities. You can get a single veneer or have your whole smile redone, in shades ranging from a pearly luster to an ultra-bright white; that's why veneers are a favorite of Hollywood stars. Getting veneers is a procedure that takes several office visits, but the beautiful results can last for many years.
If a chip or crack extends into the inner part of a tooth, you'll probably need a crown (or cap) to restore the tooth's function and appearance. As long as the roots are healthy, the entire part of the tooth above the gum line can be replaced with a natural-looking restoration. You may also need a root canal to remove the damaged pulp material and prevent infection if the fracture went too far. While small chips or cracks aren't usually an emergency (unless accompanied by pain), damage to the tooth's pulp requires prompt attention.

Today’s dental care has advanced leaps and bound over the last century. But these advances are tiny steps compared to what many believe may be coming in the next few decades. This optimism arises from our growing understanding of deoxyribonucleic acid (DNA), the chain-like molecule that houses the genetic instructions for the growth, function and reproduction of every cell in the body.
As researchers unlock the secrets of this vast genetic blueprint unique to each individual the possible applications from this knowledge are astounding. Here are just a few possibilities that could one day impact everyone’s oral health.
Preventing tooth decay. This rampant disease, triggered by bacteria (particularly Streptococcus mutans), can cause extensive damage in otherwise healthy teeth. There’s already some indications from the study of genomics that we may be able to stop or at least hinder this disease in its tracks. Already we’re seeing advances in gene therapy that might be able to inhibit the growth of Strep mutans and reduce its colonies in the mouth.
Growing new teeth. Composed of various layers, a natural tooth is part of a dynamic system of bone and gum ligaments that allow movement, protection and nourishment. Although dental implants are the closest and most advanced artificial approximation we now have to them, implants still can’t fully measure up to the function and capabilities of a natural tooth. But further insight into the genetic code may one day allow us to reproduce a living replacement tooth for a lost one.
Harnessing saliva for detecting disease. The impact of genomics related to the mouth could impact more than just the mouth itself. Researchers have discovered that saliva contains genetic information similar to blood, urine and other bodily fluids with markers for various disease conditions. Unlike other fluids, though, saliva is relatively easy to collect. The key is new equipment and testing protocols to take advantage of the information already available in a single drop of saliva.
These examples illustrate the range of possibilities for better health in the future: a reduction in dental disease early in life; new and better ways to restore missing teeth; and quicker ways to diagnose dangerous health conditions.
