Surgical exposure of hidden teeth
Sometimes teeth do not come into their natural position and stay hidden within the jawbone. These teeth are referred to as “unerupted” or “impacted”. This most commonly occurs with the upper canines (eye teeth), where they become hidden in the roof of the mouth. In such cases, surgical exposure may be necessary to reveal the hidden teeth and assist in guiding them into their correct position. However, this condition can affect any tooth or any area of the mouth.
As part of orthodontic treatment, your orthodontist will refer you to us for the surgical exposure of the hidden tooth. This is a small surgical procedure that involves exposing the tooth into the mouth and attaching a gold chain to that tooth. The orthodontist then uses the gold chain to gradually pull the tooth into its desired position during the course of orthodontic treatment.
While this procedure is generally considered a minor surgical intervention, due to the young age of most candidates and to ensure a more comfortable experience, it is preferable to perform the treatment under either intravenous sedation or general anaesthetic.
What is tooth exposure surgery?
Tooth exposure surgery is a procedure performed when a tooth has failed to erupt properly. It is most commonly done when a tooth is blocked from erupting due to dental crowding or when a baby tooth has not fallen out, preventing the eruption of an adult tooth. The procedure exposes the tooth in the mouth, allowing the orthodontist to apply forces later to move it into its ideal position.
What does tooth exposure surgery involve?
There are different techniques depending on the tooth’s position. However, the general approach involves making a small incision where the tooth is hidden. Once the incision is made and the gums are pushed aside, there is usually only a thin layer of bone covering the tooth, similar to an eggshell. This thin bone is removed until the tooth is fully exposed. Once the tooth is exposed, a gold chain is attached to it. The orthodontist will later use this chain to move the tooth into its ideal position. A couple of stitches are then placed to close the gums.
Is tooth exposure surgery performed under general anaesthetic?
It depends on the case and how anxious the patient is. The procedure can be completed under local anaesthetic, general anaesthetic, or intravenous sedation. Local anaesthetic is similar to what you receive at any dentist’s office. You get an injection, and once it takes effect, you don’t feel any pain, though you remain awake and aware of everything, without discomfort.
General anaesthetic is the other extreme. If you prefer not to be aware of the procedure, you would need to go to the hospital for general anaesthetic, where you will be put to sleep. the procedure is completed while you are asleep, and you wake up afterward.
A third option is intravenous sedation, where an anaesthetist administers medications through your veins in your arms or hands. These medications don’t put you to sleep, but they relax you deeply and take away any worries, making you feel unconcerned about the procedure.
Most people opt for general anaesthetic or intravenous sedation for added comfort, but the procedure can also be completed with local anaesthetic.
How long does recovery take after surgical exposure?
Recovery typically takes one week, although full healing may take longer. During recovery, it is essential to follow our post-operative instructions, maintain good oral hygiene, and avoid hard or chewy foods to protect the surgical site.
