Humans have two upper (maxillary) canines and two lower (mandibular) canines. Canine teeth are sometimes referred to as cuspids, fangs, or “eye teeth” because of their direct positioning beneath the eyes. Canine teeth have thicker and more conical roots than incisors and thus have an especially firm connection to the jaw. Canine teeth often have the longest root of all teeth in the human mouth and, except for wisdom teeth, are the last to fully erupt and fall into place, often around age 13.

An impacted tooth essentially means that it is blocked, stuck, or unable to fully erupt and function properly. Third molars (wisdom teeth) most commonly fall victim to impaction, but the upper canine is the second most common tooth to become impacted. Wisdom teeth serve no important function in the mouth and are frequently removed; however, impacted canines require treatment for the following reasons:

  • Closing Gaps – Canines are the last of the front teeth to fall into place and therefore close any unsightly gaps between the other upper teeth.
  • Guide the Bite – Canines play a vital role in the “biting” mechanism of the teeth. They touch first when the jaw closes, and guide the other teeth into position.
  • Proper Alignment & Function – Canine teeth are essential to the correct alignment and function of the other teeth on the dental arch. Missing or impacted canines can greatly affect the function and aesthetic appearance of the smile.

What causes canine teeth to become impacted?

There are several main causes for impacted canine teeth:

  • Extra Teeth – If extra teeth are present, the natural eruption of the canine teeth may be inhibited. The eruption progress of the canine may be directly blocked by an extra tooth or the subsequent overcrowding might leave no room on the dental arch for the canine.
  • Overcrowding – In some cases, poor alignment of the front teeth can lead to overcrowding. The existing teeth compete for space which means that the canines do not have sufficient room to become functional.
  • Unusual Growths – On rare occasions, unusual growths on the soft tissue of the gums can restrict the progress of canine teeth, which leads to later impaction.

Early and thorough examination of the teeth can pre-empt problems with impacted canines. It is important for your dentist to document the number teeth present when your child is around 7 years of age in order to record the presence or absence of canine teeth. The older the child becomes, the less likely it is that an impacted canine tooth will erupt naturally. If canine teeth are missing or very slow in fully erupting, the dentist or orthodontist will refer you to Dr. Murphy to evaluate your child for surgical exposure of the canines.

What does the treatment of impacted canines involve?

Dr. Murphy initially conducts a thorough visual examination of the teeth, accompanied by a panorex x-ray. Once the cause of the impaction has been determined, there will be several treatment options available depending upon the age of your child. The objective is to aid the eruption of the impacted canines.  He will also discuss the best choice of anesthesia to make the procedure as comfortable as possible given your child's age and the nature of the procedure.

On the day of the procedure, Dr. Murphy will surgically expose the un-erupted canine by lifting the gum and then place a special bracket that will be used to help guide the tooth in place over time.  Dr. Murphy will also extract any teeth identified by the dentist or orthodontist that are causing overcrowding in your chils's mouth.
