The Expose and Bond procedure is a surgical technique that helps bring an impacted tooth, often a canine, into its correct position. The oral surgeon works with your orthodontist to uncover the tooth and attach a bracket to guide it into the dental arch.
The Expose and Bond procedure is a minor surgical intervention performed to help an impacted tooth, most commonly the upper canine, erupt correctly. An impacted tooth is one that is stuck and unable to emerge through the gums on its own. The canine is essential for biting and establishing a functional, aesthetic smile, making it crucial to bring it into the arch.
This procedure involves the oral surgeon carefully exposing the crown of the impacted tooth within the bone and then, in collaboration with the orthodontist, bonding a small bracket and chain to it. The chain is then connected to the orthodontic archwire, which allows the orthodontist to apply gentle, constant force to slowly pull the tooth into its proper alignment over several months.
For the best prognosis, Expose and Bond is typically recommended for teenagers and young adults, when the bone is more pliable.
What to expect
Before surgery
The process begins with your orthodontist’s recommendation and initial alignment of the surrounding teeth to create space for the impacted tooth. X-Rays and 3D Imaging are used to precisely locate the tooth and determine the best approach. You will consult with the oral surgeon to discuss the procedure and Anesthesia options. Pre-operative instructions will include guidelines on diet and medications, and you must arrange for transportation home if Sedation is planned.
During surgery
The Expose and Bond procedure is performed under local Anesthesia, often with the addition of Nitrous Oxide or IV Sedation. The surgeon makes a small incision in the gum tissue to locate and expose the crown of the impacted tooth. Once the tooth is clean and dry, the orthodontist’s bracket and chain are bonded to it. The incision may be closed around the tooth, leaving only the small chain visible, or the tooth may be left uncovered. The chain is then engaged by the orthodontist to begin the slow traction process.
After surgery
Post-operative discomfort is usually minor and manageable with over-the-counter pain relievers. Swelling is typically minimal. You should adhere to a soft-food diet for a few days and follow the surgeon’s instructions for keeping the surgical site clean. The patient then returns to the orthodontist, who will activate the chain to begin guiding the tooth into place. This orthodontic movement is a slow process that will be monitored closely during follow-up visits.
The upper canine teeth are often the last front teeth to erupt, and they may become impacted due to severe crowding or an abnormal path of eruption. Early diagnosis by your dentist or orthodontist is key, as the procedure is most successful when performed before the tooth has fully fused to the bone.
The time required for the tooth to move into the arch varies significantly from patient to patient, depending on how deeply the tooth is impacted and the patient's age. The process can take anywhere from six months to a year, or sometimes longer. Patience and consistent orthodontic adjustments are necessary for success.
Once the bracket is attached, the small chain extends out and is managed by the orthodontist. It is designed to be tucked away and should not cause any significant irritation to your gums or cheek. Any initial irritation is temporary and can be managed with dental wax.
The surgical procedure itself is not painful due to the use of anesthesia. Post-operative pain is usually mild and easily managed with over-the-counter pain medication. The real "pain" in this process is the mild pressure and soreness that comes from the orthodontic forces applied to pull the tooth down, which is similar to the feeling patients get after a brace adjustment.
While the success rate is very high, if the tooth does not move after an extended period of traction, it may be deemed "ankylosed" (fused to the bone). In this rare event, the tooth may need to be surgically removed, and alternative options, such as a Dental Implant, can be discussed to replace the missing tooth.
The Expose and Bond procedure is a collaborative effort. The oral surgeon performs the surgical portion—uncovering the tooth and bonding the bracket. The orthodontist manages the "bonding" part of the process and controls the gentle forces used to guide the tooth into its final position over time.
