Exposure of Impacted Teeth

Occasionally, teeth do not come into the mouth (erupt) normally. Instead, they become impacted. Other than wisdom teeth, the upper cuspids (eye teeth) are the most frequently impacted teeth. Bicuspids (the teeth in front of the molars), and occasionally front teeth, may become impacted.

Typically, the upper cuspids erupt into the mouth between the ages of 11 and 13. If they are impacted, they will not erupt unless they are periodontally uncovered (exposed) and brought into proper position with the application of orthodontic forces. If the tooth is left alone, it will not erupt normally, and it could damage the roots of adjacent teeth or even push them out of position.


The position of the impacted tooth is determined during the examination appointment by taking digital radiographs (x-rays), which provide immediate understanding of whether the tooth is located toward the palate or the lip.

After applying topical (gel) anesthetic, local anesthetic is gently placed into the tissue around the impacted tooth. The gum tissue is gently, cautiously, moved to expose the impacted tooth, while maintaining all of the gum tissue around the adjacent teeth to avoid any periodontal damage to them. Occasionally, as necessary, some of the bone surrounding the crown of the tooth is removed.

Once the tooth is exposed, sutures will be placed to precisely reposition the gingival (gum) tissue. One week later, we will remove the sutures and cement (bond) an orthodontic bracket with a small chain to the exposed tooth. Shortly thereafter, your orthodontist will apply forces to the tooth to position it ideally in the mouth by redirecting the chain with elastic thread.
