Exposure of an Impacted Upper Canine
This leaflet has been written to help you understand your upcoming treatment. It explains what the procedure involves and answers some of the most common questions. If there’s anything you don’t understand, or if you’d like more information, please speak to your Surgeon or Orthodontist.
What is the problem?
The canine (also known as the ‘eye tooth’) usually comes through into the mouth between the ages
of 11 and 13. Sometimes, one or both canines develop in the wrong position—often lying across the
roof of the mouth, behind the front teeth. When this happens, the tooth is described as ‘impacted’
because it has not come through into its normal place.
Why do I need treatment?
- Your Orthodontist has recommended this procedure because one or both of your canines have not
erupted properly. If the tooth is left alone, it may stay trapped in the bone and could:
- Damage the roots of nearby teeth
- Push other teeth out of position
- Prevent your teeth from aligning correctly during orthodontic treatment
- By exposing the tooth, your Orthodontist can help guide it into its correct position as part of your overall treatment plan.
What does the treatment involve?
The procedure to help your tooth erupt is a minor surgical operation. It usually takes place under a
day case general anaesthetic, meaning you will be asleep for the procedure but able to go home the same day.
During the operation:
- The gum over the impacted canine is carefully lifted back.
- Occasionally, a small amount of bone covering the tooth is also removed to uncover the crown
(the top part of the tooth).
How will the Orthodontist move the tooth into position?
Once the tooth is exposed, one of the following methods will be used—this will already have been
discussed with you before surgery:
1. Bracket and Chain
A small bracket is glued to the surface of the tooth. A fine chain attached to the bracket allows your Orthodontist to gently pull the tooth into the correct position over time. The chain is delicate, so you should eat carefully for the first few weeks after surgery.2. Plate
A small window is made in the gum over the tooth, and a plastic ‘dressing’ plate is fitted to cover the area. This plate clips onto your back teeth and must be worn all the time, except when cleaning your teeth. Wearing the plate prevents the gum from growing back over the exposed tooth.3. Pack
In some cases, a small antiseptic gauze pack is placed over the exposed tooth and held in position with stitches. This pack is removed after a few weeks. If it comes loose or falls out, contact your dental department for advice. Sometimes, the gum is held back in place with dissolvable stitches, which usually disappear within about two weeks.Will there be much pain or swelling?
This procedure is not usually very painful. You may experience some soreness or mild discomfort
for a few days afterwards, but swelling is generally minimal. Your Surgeon will prescribe pain relief if needed. Antibiotics are not normally required.
Will I need another appointment?
Yes. You will have a follow-up appointment a few weeks after the procedure so your Surgeon or
Orthodontist can check how the area is healing. You will also continue to have regular orthodontic appointments as part of your ongoing treatment.
