You don’t have to be a dental professional to appreciate a beautiful smile. Likewise, you’ll also know when something’s not quite right with one.
Such can be the case when a tooth fails to erupt properly, causing most or all of the crown to remain below the gum line, a condition known as impaction. Upper canines (or “eyeteeth,” for their location in the arch under the eyes) are especially susceptible to impaction: located on either side of the lateral incisors, which are on either side of the central incisors (the two center front teeth).
The upper canines are important both for function and appearance. Working with their lower counterparts they help cut through food as we chew, so you lose some of that efficiency when they don’t erupt properly. Impacted teeth are susceptible to abscesses and cysts, and can impinge upon and damage the roots of other teeth. And just as importantly, their absence also disrupts the smile as nearby teeth tend to move or “drift” toward the open space.
Rather than remove the impacted canines as is often done with back teeth, it may be more advantageous for both function and appearance to “coax” them into full eruption. This requires first pinpointing their exact location below the gums using x-rays or cone beam 3-D imaging.
If the teeth are in reasonably good position we must first prepare them for orthodontic treatment by surgically exposing the crown from the gums and bonding a small bracket to it. We then attach a small gold chain to the bracket that extends outside of the gums when we suture them back into place. The chain is attached to orthodontic hardware that exerts pressure on the impacted tooth for several months to “pull” it out into the arch.
This procedure has the best chance of success if undertaken before the end of jaw development in early adulthood. Otherwise, it may be better to remove the impacted canines and replace them with dental implants, followed by orthodontic treatment of other teeth to restore their proper position and bite relationships. In either case, your impacted upper canines don’t have to be a problem — we can restore both your mouth function and your smile.

If you’ve had a total joint replacement or similar procedure, you will want your surgeon to decide if you need to take an antibiotic before you undergo dental work. This is a precaution to prevent a serious infection known as bacteremia.
Bacteremia occurs when bacteria become too prevalent in the bloodstream and cause infection in other parts of the body, especially in joints and bone with prosthetic (replacement) substances. It’s believed that during invasive dental procedures bacteria in the mouth can enter the bloodstream through incisions and other soft tissue disruptions.
Joint infections are a serious matter and can require extensive therapy to bring it under control. Out of this concern, the use of antibiotics as a prophylactic (preventive measure) against bacteremia once included a wide range of patients for a variety of conditions and procedures. But after an in-depth study in 2007, the American Dental Association concluded that the risks for many of these patient groups for infection triggered by a dental procedure was extremely low and didn’t warrant the use of antibiotic premedication therapy.
As a result, recommendations for antibiotic therapy changed in 2009, eliminating many groups previously recommended for premedication. But because of the seriousness of joint infection, The American Academy of Orthopedic Surgeons still recommends the therapy for joint replacement patients about to undergo any invasive procedure, including dental work. It’s especially needed for patients who also have some form of inflammatory arthritis, a weakened immune system, insulin-dependent diabetes, hemophilia, malnourishment or a previous infection in an artificial joint.
The guidelines for antibiotic premedication can be complex. It’s best, then, to speak with both your orthopedic surgeon and us about whether you should undergo antibiotic therapy before you undergo a dental procedure. The ultimate goal is to reduce the risks of any disease and to keep both your mouth and your body safe from infection.
