Specialist Care for Impacted or Unerupted Teeth
Surgical exposure is a minor oral surgery performed when a tooth has not erupted into its natural position. This often affects the upper canines, which can remain impacted in the roof of the mouth, although any tooth may be affected. By exposing the hidden tooth and preparing it for orthodontic movement, surgical exposure helps ensure the tooth can be guided safely into its ideal position.
As part of orthodontic treatment, your orthodontist may refer you to us for this procedure. Surgical exposure involves revealing the impacted tooth and attaching a small gold chain to it. After the procedure, your orthodontist gently applies traction to guide the tooth into place over time. This coordinated approach ensures predictable results and supports long term dental stability.
How Surgical Exposure Works
This procedure is generally considered minor, but because many candidates are children or teens, it is often performed under intravenous sedation or general anaesthetic for comfort. During the procedure, a small incision is made over the site of the impacted tooth. A thin layer of bone, similar to an eggshell, is removed to fully uncover the tooth.
Once visible, a gold chain is attached securely to the tooth. The gums are positioned back with a couple of stitches, and the orthodontist uses the chain during treatment to gradually move the tooth into alignment.
Crown Lengthening
Crown lengthening is a dental procedure that reshapes the gum tissue, and sometimes the underlying bone, to expose more of a tooth’s surface. It is a procedure that increases the amount of visible tooth structure.
Purpose:
This procedure can be performed for restorative purposes, to prepare a tooth for a crown, or for cosmetic reasons, to improve the appearance of a ‘gummy smile’.
Restorative purposes:
When a tooth is fractured or decayed below the gum line, crown lengthening creates enough space for a proper restoration, such as a crown. It ensures there is sufficient tooth structure for a secure and stable restoration.
Cosmetic Concerns:
‘Gummy smile’ correction: If excessive gum tissue covers the teeth, crown lengthening can create a more balanced and aesthetically pleasing smile. It can also correct asymmetries in the gum line, resulting in a more harmonious appearance.

FAQs
What is tooth exposure surgery?
Tooth exposure surgery is performed when a tooth has failed to erupt naturally. This can be due to crowding, an over-retained baby tooth or limited space. The procedure uncovers the tooth so the orthodontist can guide it into its proper position during treatment.
What does tooth exposure surgery involve?
Depending on the tooth’s location, a small incision is made where the tooth is hidden. After lifting the gum, a thin layer of bone is removed to expose the tooth surface. A gold chain is then bonded to the tooth, and stitches are placed to close the area. The orthodontist applies gentle force over time to move the tooth into alignment.
Is tooth exposure surgery performed under general anaesthetic?
Yes, it can be. The procedure may be completed under local anaesthetic, intravenous sedation or general anaesthetic. Local anaesthetic keeps you awake but comfortable. Intravenous sedation relaxes you deeply without putting you fully to sleep. General anaesthetic is performed in hospital and allows the procedure to be completed while you are fully asleep. Most patients choose sedation or general anaesthetic for added comfort.
How long does recovery take after surgical exposure?
Initial recovery usually takes about one week, though complete healing can take longer. To support healing, it is important to follow post-operative instructions, maintain good oral hygiene and avoid hard or chewy foods that may disturb the surgical site.
Will I need follow up appointments after the procedure?
Yes. Follow up visits help us monitor healing and ensure the gold chain remains secure. Your orthodontist will also schedule adjustments as the tooth begins to move into its ideal position.
