What makes an attractive smile? Of course, shiny, straight and defect-free teeth are a big factor. But there’s another equally important element: all your teeth have come in.
Sometimes, though, they don’t: one or more teeth may remain up in the gums, a condition known as impaction. And if they’re in the front like the upper canines (the pointed teeth on either side of the front four incisors) your smile’s natural balance and symmetry can suffer.
Impaction usually happens due to lack of space on a small jaw. Previously erupted teeth crowd into the space of teeth yet to come in, preventing them from doing so. As a result the latter remain hidden within the gums.
While impaction can interfere with the smile appearance, it can cause health problems too. Impacted teeth are at higher risk for abscesses (localized areas of infection) and can damage the roots of other teeth they may be pressing against. That’s why it’s desirable for both form and function to treat them.
We begin first with an orthodontic examination to fully assess the situation. At some point we’ll want to pinpoint the impacted teeth’s precise location and position. While x-rays are useful for locating impacted teeth, many specialists use cone beam CT (CBCT) technology that produces highly detailed three-dimensional images viewable from different vantage points.
If the tooth is in too extreme a position, it might be best to remove it and later replace it with a dental impact or similar restoration once we’ve completed other necessary orthodontic treatment. But if the tooth is in a reasonable position, we might be able to “move” the tooth into its proper place in the jaw in coordination with these other tooth-movement efforts to make room for it.
To begin this process, an oral surgeon or periodontist surgically exposes the tooth crown (the normally visible portion) through the gums. They then bond a small bracket to the crown and attach a small gold chain. An orthodontist will attach the other end to orthodontic hardware that will exert downward pressure on the tooth to gradually bring it into normal position.
Dealing with impacted teeth of this nature is often part of a comprehensive effort to correct the bite. If we’re successful, it could permanently transform both the smile and overall dental health.

Autumn begins in the month of September, a season that promises cooler days and longer nights. But more significantly for sports fans, September marks the start of football season. Football remains America’s favorite spectator sport—and it’s also played by countless college and high school athletes, as well as those who enjoy an occasional pickup game in the back yard or on the beach. Yet, like many contact sports, football (even touch football) carries a risk of injury—and one of the areas of the body most vulnerable to injury is the mouth.
Some of the most common dental injuries in contact sports include lacerations (cuts), tooth fractures, displacement (teeth pushed deeper into or out of their sockets), knocked-out teeth, and temporomandibular joint problems. While it’s hard to pin down the exact statistics, researchers estimate that over 5 million teeth are avulsed (completely knocked out) every year in the U.S. alone—a significant number of which are due to sports injuries. It is also estimated that the lifetime cost to treat an avulsed tooth ranges from $5,000 to $20,000!
Given the prevalence of sports-related dental injuries, it’s no wonder that protective devices have been developed to minimize the risk. Properly fitted mouthguards have been shown time and again to be effective at preventing many types of dental injuries. Yet the use of devices isn’t always required by rule-making organizations—and many casual players don’t use them at all. That’s a shame, because so many of the injuries are preventable.
Custom-made mouthguards are available right here at the dental office. Strong and durable, these protective devices are specially fabricated from a model of the player’s own teeth. That means they offer the maximum protection, yet can be comfortably worn during practices, backyard games or championships—an important consideration, since accidents often happen when least expected. (And if you’re a parent of a child who plays sports, that’s probably something you already know.)
It isn’t just football players who can benefit from mouthguards: Those with a passion for soccer, basketball, baseball, martial arts, and dozens of other sports can also get the protection they need from this small (but important) item. So this season, when you’re watching or playing your favorite game, think about the extra safety and peace of mind you could gain from a custom-made mouthguard.

What do young saber tooth tigers, which have been extinct about 10,000 years, have in common with human kids today? At first glance, not a lot. Smilodon fatalis, the big cat of North America, reached adulthood at around age three and weighed up to 600 pounds. But these ice-age mammals are probably best known for their dagger-like canine teeth, which (as shown by many well-preserved skeletons) grew up to 7 inches long. And that’s where the comparison between kids and kitties gets interesting.
The toothy felines had primary (baby) teeth and adult teeth, which developed in a similar way to human dentition. The primary teeth came in first, persisted during the young cat’s development, and shared space in the mouth as the adult teeth were erupting (growing in) — with one big difference. According to a recent study reported in the academic journal PLOS ONE, those colossal canines grew at an astonishing rate: up to 6 millimeters per month! By comparison, human primary teeth emerge from the gums at around 0.7mm per month, while permanent teeth may grow up to 2mm per month.
It’s understandable why those tiger teeth developed so rapidly: Life in the Ice Age was hard, and predators needed every advantage just to stay alive. But while human baby teeth take longer to develop (and to go away), they, too, are vitally important.Â For one thing, the primary teeth let kids bite, chew, speak (and smile) properly, until they are replaced by adult teeth — a process that isn’t usually finished until a child reaches the age of 12-13. So those “baby” teeth allow kids to have good nutrition — and positive social interactions — for a significant part of childhood!
There’s another important thing primary teeth do before they’re gone: They help ensure that the succeeding teeth come in properly, by holding a space in the jaw that will later be filled by a permanent tooth. If baby teeth are lost prematurely, those spaces can close up, resulting in permanent teeth that emerge too close together, or in the wrong places. This condition, called malocclusion (bad bite), can usually be corrected by orthodontics. But it’s better to avoid the inconvenience (and cost) of braces, if possible.
That’s why it’s so important to take care of your child’s baby teeth. Even though they won’t be around forever, they have a vital role to play right now. So be sure proper attention is paid to your child’s oral hygiene: That means avoiding sugar, and remembering to brush and floss every day. And be sure to come in regularly for routine exams, cleanings, and needed care. It’s the best way to keep those little teeth from “going extinct” too soon!
