We instinctively know when a smile looks normal—and when it doesn't. It could be that something simply looks out of place like crooked teeth. But we might also notice when something is missing—as with one or both of the canine teeth.
The canine teeth align just under the eyes and are recognizable by their pointed ends. When they're missing, the smile looks “incomplete.” But “missing” in this case could mean “invisible”—the teeth are there, but hidden within the gums because they failed to come in properly and became impacted. This often happens on a smaller jaw where other teeth have crowded into the space intended for them.
Fortunately, we may have a remedy, and not just for appearance's sake—any impacted tooth can cause health problems, from gum abscesses to root damage of neighboring teeth. Although this might necessitate their surgical removal, we might also be able to coax them through the gums into better position in the jaw, if they're in a reasonably good position. This could result in both a boost to a patient's oral health and a more normal looking smile.
First, though, a patient will need to undergo a thorough bite evaluation by an orthodontist. Besides pinpointing the impacted teeth's precise location with x-rays or CT technology, an orthodontist will also want to assess the positions and condition of the rest of the teeth. If the conditions are right and there's enough room in the jaw, the orthodontist may recommend drawing the impacted canines into proper alignment in the jaw.
The process starts when an oral surgeon exposes the impacted teeth by surgically cutting through the gum tissue. They then attach a small bracket to the tooth with a tiny metal chain attached, the other end of which is looped over orthodontic hardware attached to other teeth. The tension on the chain by the hardware gradually nudges the teeth downward out of the gums. This is usually done in coordination with other measures to fully correct the bite.
If the procedure is successful, bringing the canines out of impaction reduces the problems those teeth could cause the person's oral health. But just as important, it can restore normality to their smile.

Remembered fondly by fans as the wacky but loveable Carlton on The Fresh Prince of Bel-Air, Alfonso Ribeiro is currently in his fifth year hosting America's Funniest Videos. It's the perfect gig for the 48-year-old actor, who loves to laugh and make others laugh as well. This is quite the opposite experience from one he had a few years ago that he remembers all too well: a severely decayed tooth.
After seeing his dentist for an intense toothache, Ribeiro learned he had advanced tooth decay and would need root canal treatment. Ribeiro wasn't thrilled by the news. Like many of us, he thought the procedure would be unpleasant. But he found afterward that not only was the root canal painless, his toothache had vanished.
More importantly, the root canal treatment saved his tooth, as it has for millions of others over the last century. If you're facing a situation similar to Alfonso Ribeiro's, here's a quick look at the procedure that could rescue your endangered tooth.
Getting ready. In preparation for root canal therapy, the tooth and surrounding gums are numbed, often first with a swab of local anesthesia to deaden the surface area in preparation for the injection of the main anesthesia below the surface. A dental dam is then placed to isolate the infected tooth from its neighbors to prevent cross-contamination.
Accessing the interior. To get to the infection, a small access hole is drilled. The location depends on the tooth: in larger back teeth, a hole is drilled through the biting surface, and in front teeth, a hole is drilled on the backside. This access allows us to insert special tools to accomplish the next steps in the procedure.
Cleaning, shaping and filling. Small tools are used to remove the diseased tissue from the interior tooth pulp and root canals. Then the empty spaces are disinfected. This, in effect, stops the infection. Next, the root canals inside the tooth are shaped to allow them to better accept a special filling called gutta percha. The access hole is then sealed to further protect the tooth from future infection, and a temporary crown is placed.
A new crown to boot. Within a couple weeks, we'll cap the tooth with a long-lasting lifelike crown (or a filling on certain teeth). This adds further protection for the tooth against infection, helps strengthen the tooth's structure, and restores the tooth's appearance.
Without this procedure, the chances of a tooth surviving this level of advanced decay are very slim. But undergoing a root canal, as Alfonso Ribeiro did, can give your tooth a real fighting chance.

For some, the excitement over their braces coming off gets dampened a bit with the prospect of now having to wear a retainer. But it has to be—newly realigned teeth have a tendency to revert to their previous positions out of a kind of “muscle memory.” A retainer prevents that from happening.
But as essential as it is, the standard retainer is almost as noticeable as braces, a major reason why many patients are less than enthusiastic about wearing them. And, because it's common for them to become lost when out of the mouth, replacing one becomes an added expense.
But there's another option—the bonded retainer. This retainer consists of a metal wire bonded to the back of the teeth to prevent them from moving. Because it's fixed in place, only a dentist can remove it.
The bonded retainer addresses the previous two issues associated with a removable retainer. Because it's behind the teeth rather than in front, it's out of sight to others. And, because it's fixed in place, there's no danger of losing it.
But unlike its removable cousin, which can be taken out for oral hygiene, the bonded retainer can make flossing more difficult. And, by nature, a bonded retainer must be worn all the time; a removable retainer allows for a more flexible schedule later in the treatment of a few hours a day.
So, which retainer option is best for you or another family member? A bonded retainer may be more attractive for appearance's sake, if it must be worn indefinitely, or if there's a high probability of the teeth moving out of alignment. And, it might be the right choice where there's a concern about a patient's ability to keep up with a removable retainer.
If you do decide to go with a bonded retainer, ask your dental hygienist for training on using floss with the fixed appliance—this can help improve oral hygiene. Whatever you choose, bonded or removable, your retainer will help you keep that new, beautiful, straightened smile.

Correcting a bite problem involves more than applying braces. Orthodontists must consider a wide range of factors, including the type of bite problem involved, complications like impacted or missing teeth, and their patient's overall dental condition.
Orthodontists must also keep in mind the future—how will a treatment implemented now impact a patient's appearance and dental function many years from now? In reality, orthodontists perform these treatments within a dynamic growth environment, especially involving children and teenagers whose mouth and facial structures are still maturing.
And although these growth changes slow in adulthood, they don't stop—orofacial structures continue to change throughout life. For example, a person's lips steadily thicken in size until the mid-teen years, and then slowly thin out over the rest of their lifetime. The distance between the lips both at rest and while smiling may also narrow in later years. Other changes continue to occur in the bones and soft tissues of the mouth and face.
Fortunately, this structural growth follows a fairly consistent track. Although variations do occur, an orthodontist can project the growth changes their patients will undergo as they age, and use that knowledge to plan out bite treatment. With this understanding, orthodontists plan not only what treatments will be needed, but when to perform them, and to what extent.
This may involve a number of treatment stages, spaced out to coincide with regular development. An orthodontist may focus first on general bite correction to bring the teeth and jaws into a reasonable state of alignment. Later, they'll use more refined methods to fine-tune corrections that better align with later adult growth.
More intensive treatments may be necessary to build a foundation for future treatment. For example, orthognathic surgery may be needed to correct a severe case of an over-extended lower jaw. During the procedure, surgeons move the lower jaw to a joint position higher on the skull. This retracts the lower jaw into a more normal alignment with the upper jaw, and can dramatically change the facial profile for the better.
Each orthodontic patient is different, and each requires their own a unique treatment plan. That plan has a greater chance of long-term success by applying knowledge of future growth changes.

The mouth is a crowded place with nerves, blood vessels and sinus cavities sharing common space with the teeth and gums. Although important in their own right, these structures can also hinder treatment for complex dental situations like dental implant surgery or impacted teeth.
Treating these and similar situations depends on getting an accurate depiction of “what lies beneath.” Conventional x-rays help, but their two-dimensional images don't always give the full picture. There's another way—cone beam computed tomography (CBCT).
Similar to CT scanning, CBCT uses x-ray energy to take hundreds of “sliced” images that are then re-assembled with special software to create a three-dimensional model viewable on a computer screen. CBCT is different, though, in that it employs a scanning device that revolves around a patient's head, which emits a cone-shaped beam of x-rays to capture the images.
A dentist can manipulate the resulting 3-D model on screen to study revealed oral structures from various angles to pinpoint potential obstacles like nerves or blood vessels. The detailed model may also aid in uncovering the underlying causes of a jaw joint disorder or sleep apnea.
CT technology isn't the only advanced imaging system used in healthcare. Another is magnetic resonance imaging (MRI), which excites hydrogen atoms in water molecules. This produces different vibration rates in individual tissue structures, which are then translated into detailed images of these structures. Unlike CT or CBCT, MRI doesn't use x-ray energy, but rather a magnetic field and radio waves to produce the atomic vibrations.
But while providing good detail of soft tissues, MRI imaging doesn't perform as well as CBCT with harder tissues like bone or teeth. As to the potential risks of CBCT involving x-ray radiation exposure, dentists follow much the same safety protocols as they do with conventional x-rays. As such, they utilize CBCT only when the benefits far outweigh the potential x-ray exposure risks.
And, CBCT won't be replacing conventional x-rays any time soon—the older technology is often the more practical diagnostic tool for less invasive dental situations. But when a situation requires the most detailed and comprehensive image possible, CBCT can make a big difference.
