ExposingandPreservingImpactedCanineTeeth

The final emergence of permanent teeth in late adolescence marks the end of a long process beginning in the womb with the formation of our primary or “baby” teeth. Permanent teeth form in a similar way as buds high in the jaw, continuing to grow until the primary teeth ahead of them fall away. The crowns of the new adult teeth eventually break through the gum tissue and emerge (erupt) into view.

At least, that’s normally what should happen; sometimes, though, a tooth may only erupt partially or not at all, a condition known as impaction. The crown remains partially or fully submerged below the gum line, causing the tooth to press against other teeth, potentially damaging them. It can also make periodontal (gum) tissues adjacent to the area more susceptible to disease. Wisdom teeth are especially prone to this kind of impaction, to the extent they’re often surgically removed (extracted) to avoid future problems to adjacent teeth or the bite.

Upper canines (the “eye teeth” normally located directly below the eyes) are also subject to impaction. But because of their highly visible position, extracting them could have an adverse impact on the patient’s smile. In this case, we often attempt instead to expose and ultimately save the tooth.

Before taking any action, however, an orthodontic examination is conducted first to pinpoint the exact position of the impacted tooth and determine how that position might affect moving teeth into a more desired alignment. If we find the impacted canine is in a workable position, the next step is to surgically uncover the tooth from the gum tissue (a minor procedure usually performed by an oral surgeon or periodontist). Once exposed, an orthodontic bracket with a small attached gold chain is bonded to the tooth. The gums are then sutured back into place with the chain exposed and allowed to heal.

At some future point an orthodontist will attach the chain to orthodontic hardware that will pull the impacted tooth into proper position over several months. As a result, the upper canine becomes “un-impacted”; the dangers to surrounding teeth and tissues are also reduced. And, just as important, we can preserve the tooth and with orthodontics achieve an attractive, normal smile.

PatientsonBloodThinnersRequirePrecautionsBeforeandDuringOralSurgery

The proliferation of drugs to treat all manner of diseases and conditions has heightened concerns not only about general side effects, but also how a particular drug may affect treatments for other conditions. There are indications, for example, that drugs classified as blood thinners could cause complications for patients undergoing oral surgery.

Blood thinners like Warfarin are typically prescribed to patients with artificial heart valves or who are at significant risk for stroke, heart attack, or the formation of clots that could potentially damage the heart and lungs. The drug reduces the coagulation (clotting) mechanism in blood; aspirin taken regularly should also be considered a blood thinner.

As with any invasive procedure, blood thinners can complicate oral surgery. Blood doesn’t clot normally and so bleeding during a procedure is more difficult to stop. This doesn’t necessarily mean the surgery can’t be performed. For one thing, many oral procedures like tooth removal involve little trauma to tissues and bleeding in the hands of a careful and experienced surgeon. The surgeon can also use hemostatic agents during surgery that will stabilize blood clotting, as well as suturing the incision in such a way as to reduce bleeding from surface capillaries. In the case of a tooth extraction, a bone graft placed within the empty socket not only reduces bone loss from a missing tooth, but can also enhance bleeding control.

In consultation with your medical doctor, it’s also possible to temporarily stop or reduce your medication dosage in anticipation of a pending oral surgery. While it may not be safe to stop the drug altogether, a reduced dosage can ease the anti-coagulant effect and reduce any complications from bleeding that might occur during the surgery. You can then resume normal dosage soon after the procedure.

During your pre-op examination, it’s important to let your surgeon know about any drugs you are currently taking, including over-the-counter drugs like aspirin. The oral surgeon will then be able to take the necessary steps, including working with your medical doctor, to ensure your surgical procedure is safe and uneventful.
