What does "impacted" mean?
A wisdom tooth is impacted when it cannot erupt into a normal position. It may lean forward into the second molar (mesioangular), lie on its side (horizontal), tilt backwards, or sit upright but stay buried in bone. Some are partly visible through a small opening in the gum; others cannot be seen at all and show up only on an X-ray.
Because these teeth are blocked by bone or by the neighbouring molar, they cannot simply be lifted out the way a fully erupted tooth can. Removal is a minor surgical procedure. For teeth that have come in straight, see our page on routine wisdom tooth extraction.
Signs an impacted wisdom tooth is causing trouble
- A sore, swollen gum flap at the back of the mouth, sometimes with a bad taste
- Pain spreading to the ear, jaw joint or throat
- Difficulty opening the mouth fully
- Food packing behind the second molar and recurring bad breath
- A cavity or bone loss on the back of the second molar, found during a check-up
Some impacted teeth cause no symptoms for years. In that case we may simply monitor them during your regular dental check-ups and recommend removal only if a problem starts to develop.
Who is a good candidate, and when we suggest an alternative
Surgical removal is usually advised for impacted teeth that have caused infection, are damaging the adjacent molar, or are associated with a cyst. Younger adults often heal faster because roots are not fully formed and bone is more flexible, which is one reason dentists sometimes suggest planned removal before problems arise.
For a tooth whose roots wrap around the nerve canal, removing only the crown and leaving the roots (coronectomy) or referral to a hospital oral and maxillofacial surgery department may be safer. Patients with heart disease, diabetes, osteoporosis medication or blood thinners need extra planning; we review your medical history in detail and coordinate with your doctor when appropriate.
Step by step: impacted tooth surgery at E&D Dental
- 3D assessment. A scan on our low-dose CBCT unit shows the tooth's angle, root curvature and its exact relationship to the inferior alveolar nerve. Flat panoramic X-rays can hide this overlap; 3D imaging helps us plan the safest route.
- Consultation. We show you the scan, outline expected difficulty and healing time, and answer questions before you decide.
- Comfort-focused numbing. Our 3-step painless anesthesia begins with a topical gel or gargle, continues with Endo-Frost cold numbing of the injection point, and finishes with a computer-controlled delivery device, sometimes combined with electric-stimulation anesthesia.
- Surgical access. A small gum flap is opened. Where bone covers the tooth, a minimal amount is removed.
- Sectioning. The tooth is usually divided into smaller pieces so it can come out with less force and less bone removal.
- Cleaning and stitching. The socket is rinsed and closed. A vital-sign monitor follows your blood pressure and heart rate during surgery, which is especially useful for older patients and those with chronic illness.
Healing after surgery
Expect more swelling than after a simple extraction. It typically builds for two to three days, then subsides over the following week. Some bruising on the cheek is possible. Practical tips:
- Rest with your head raised on the first night
- Apply cold compresses for the first day
- Stay on soft foods such as rice porridge, eggs and tofu for several days
- Do not smoke or drink alcohol while the wound is healing
- Keep the rest of your mouth clean and rinse gently as directed
We usually see you again in about a week. When jaw stiffness lingers, our TMJ physical therapy device can be used to help ease pain and inflammation around the surgical area.
Risks you should know about
Possible complications include dry socket, infection, prolonged bleeding, limited mouth opening and damage to the neighbouring tooth. The most discussed risk is nerve irritation, which can cause numbness or tingling of the lower lip, chin or tongue; this is usually temporary but can rarely be long-lasting. For upper teeth, a small opening into the sinus can occur. Careful 3D planning reduces these risks but cannot eliminate them, and we explain your individual risk level based on your own scan.
