An impacted tooth has not erupted normally and remains partly or completely within the bone or beneath the gum. Wisdom teeth are commonly affected, but other teeth, such as canines, can also be impacted. Its position and effect on nearby structures matter more than the label alone.
Does it always need removal?
No. The decision depends on symptoms, disease, the possibility of monitoring and the wider treatment plan. Some teeth can be observed, while others need intervention. In selected cases, surgical exposure and orthodontic guidance into the arch may be considered.
How is its position assessed?
A mouth examination is combined with appropriate imaging. Nearby roots, nerves and other structures need consideration. A three dimensional scan is not automatically required. It is selected when the extra information could change management.
What should you report?
Repeated pain, swollen gum, an unpleasant taste or difficulty opening the mouth can be relevant. Rapidly increasing swelling or difficulty swallowing or breathing requires urgent medical help.
Before deciding, ask about the benefits and risks of treatment and observation. If the tooth is left in place, agree on monitoring. A painless tooth can still need review, but an absence of symptoms is not itself a reason to remove every impacted tooth preventively.
