Impacted Canines

An impacted tooth simply means that it is “stuck” and cannot erupt into function. Patients frequently develop problems with impacted third molar (wisdom) teeth. These teeth get “stuck” in the back of the jaw and can develop painful infections among a host of other problems (see Impacted Wisdom Teeth under Procedures). Since there is rarely a functional need for wisdom teeth, they are usually extracted if they develop problems. The maxillary cuspid (upper eyetooth) 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 and 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 tighter together. If a cuspid tooth gets impacted, every effort is made to get it to erupt into its proper position in the dental arch. The techniques involved to aid eruption can be applied to any impacted tooth in the upper or lower jaw, but most commonly they are applied to the maxillary cuspid (upper eye) teeth. Sixty percent of these impacted eyeteeth are located on the palatal (roof of the mouth) side of the dental arch. The remaining impacted eye teeth are found in the middle of the supporting bone but stuck in an elevated position above the roots of the adjacent teeth or out to the facial side of the dental arch.

Early Recognition Of Impacted Eyeteeth Is The Key To Successful Treatment

The older the patient, the more likely an impacted eyetooth will not erupt by nature’s forces alone even if the space is available for the tooth to fit in the dental arch. The American Association of Orthodontists recommends that a panorex screening x-ray, along with a dental examination, be performed on all dental patients at around the age of seven years to count the teeth and determine if there are problems with eruption of the adult teeth. It is important to determine whether all the adult teeth are present or are some adult teeth missing. Are there extra teeth present or unusual growths that are blocking the eruption of the eyetooth? Is there extreme crowding or too little space available causing an eruption problem with the eyetooth? This exam is usually performed by your general dentist or hygienist who will refer you to an orthodontist if a problem is identified. Treatment may also require referral to an oral surgeon for extraction of over-retained baby teeth and/or selected adult teeth that are blocking the eruption of the all-important eyeteeth. The oral surgeon will also need to remove any extra teeth (supernumerary teeth) or growths that are blocking eruption of any of the adult teeth.

What Happens If The Eyetooth Will Not Erupt When Proper Space Is Available?

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. Most of the time, the gum will be returned to its original location and sutured back with only the chain remaining visible as it exits a small hole in the gum.

Shortly after surgery (1-14 days) the patient will return to the orthodontist.
