Impacted Canines

An impacted tooth simply means that it is “stuck” and can not erupt into function. The maxillary cuspid (upper cuspid) is the second most common tooth to become impacted. The cuspid tooth is a critical tooth in the dental arch and plays an important role in your “bite”. The cuspid teeth are very strong biting teeth which have the longest roots of any human teeth. They are designed to be the first teeth that touch when your jaws close together so they guide the rest of the teeth into the proper bite.

Normally, the maxillary cuspid teeth are the last of the “front” teeth to erupt into place. They usually come into place around age 13 and cause any space left between the upper front teeth to close tight together. If a cuspid tooth gets impacted, every effort is made to get it to erupt into its proper position in the dental arch. In cases where the canine will not erupt spontaneously, the orthodontist and oral surgeon work together to get these unerupted canines to erupt. Each case must be evaluated on an individual basis but treatment will usually involve a combined effort between the orthodontist and the oral surgeon. The most common scenario will call for the orthodontist to place braces on the teeth (at least the upper arch). A space will be opened to provide room for the impacted tooth to be moved into its proper position in the dental arch. If the baby canine has not fallen out already, it is usually left in place until the space for the adult canine is ready. Once the space is ready, the orthodontist will refer the patient to the oral surgeon to have the impacted canine exposed and bracketed.

In a simple surgical procedure performed in the surgeon’s office, the gum on top of the impacted tooth will be lifted up to expose the hidden tooth underneath. If there is a baby tooth present, it will be removed at the same time. Once the tooth is exposed, the oral surgeon will bond an orthodontic bracket to the exposed tooth. The bracket will have a miniature gold chain attached to it. The oral surgeon will guide the chain back to the orthodontic arch wire where it will be temporarily attached. Sometimes the surgeon will leave the exposed impacted tooth completely uncovered by suturing the gum up high above the tooth or making a window in the gum covering the tooth. Most of the time, the gum tissue will be returned to its original location and sutured back with only the chain remaining visible as it exits in the future position of the tooth. The surgery to expose and bracket an impacted tooth is a very routine surgical procedure that is performed in the oral surgeon’s office. The procedure is generally scheduled for an hour depending on how many teeth are being treated. You can expect a limited amount of bleeding from the surgical sites after surgery. Although there will be some discomfort after surgery at the surgical sites, most patients find Tylenol or Advil to be adequate to manage any pain they may have.
