Luxation

This is a procedure where we have an unerupted tooth stuck in the jawbone well after is should have erupted and usually pertains to a posterior molar. This often occurs in 2nd molars and more often on the lower jaw. The problem is usually noticed by the dentist or orthodontist. On radiograph or x-ray, we see the second molar covered by bone and or tissue and is angled forward next to the tooth in front if it. This stuck tooth has minimal chance of erupting or straightening up on its own to erupt. If the dentist and orthodontist are worried this tooth wont erupt, a procedure called exposure with luxation is often done. During the exposure and luxation, the stuck normal molar is uncovered and once the wisdom tooth is removed, the stuck tooth is luxated or minimally moved to help it straighten vertically and put it on a path to help it erupt normally. There is a fine line between luxation and extraction of a tooth. Often the wisdom tooth behind this tooth is right up against this stuck tooth and is removed at the same time as the exposure and luxation. Prognosis for this procedure varies with how impacted the tooth we are trying to help erupt has developed and the angle of its eruption path. The more vertical the tooth, the better the prognosis for the exposure and luxation procedure. The exposure and luxation procedure has the least risk for devitalization of the tooth if we have less than two-thirds of the root formed on the tooth being luxated. The more formed the root is of this stuck tooth, the more risk we have of devitalization (the tooth dying by losing its blood supply and needing endodontic or root canal therapy).  Dr. Rotas or Dr. Martin will review your radiographs with you and help assess if this is the treatment indicated for your child.
