Finding out that your wisdom tooth is close to a nerve can feel worrying. You may wonder whether the tooth can be removed safely and what the procedure will involve. Wisdom teeth, also called third molars, are the last adult teeth to develop. They usually appear during the late teenage years or early adulthood. Because there may not be enough room in the jaw, these teeth can become trapped beneath the gums or grow at an unusual angle.
If you are looking for a dentist in Richmond to assess a wisdom tooth near a nerve, understanding the treatment process can help you feel more prepared. Careful planning, appropriate dental imaging, and suitable surgical techniques help your dental team evaluate the risks and choose the right approach for your needs.
Why Can Wisdom Teeth Grow Close to Nerves?
The lower jaw contains a major nerve called the inferior alveolar nerve. It travels through a canal in the jawbone and provides feeling to the lower teeth, lower lip, and chin. The roots of lower wisdom teeth can sometimes grow very close to this nerve canal or appear to touch it on dental X-rays.
Removing a wisdom tooth in this position may require extra care. Several factors can make the procedure more complex:
- Impacted wisdom teeth: The tooth remains partly or completely trapped beneath the gums or jawbone.
- Curved roots: The roots may bend, hook, or grow in unusual directions.
- Close nerve positioning: The roots may lie directly beside the nerve canal or appear to overlap it on an X-ray.
- Unusual jaw structure: The shape of the roots, thickness of the jawbone, and position of nearby structures can affect the surgical approach.
Not every wisdom tooth near a nerve requires surgery. Your dentist will assess its position, symptoms, and potential risks before recommending treatment.
How Dentists Check Whether a Wisdom Tooth Is Near a Nerve
Dental imaging helps your dentist understand the position of your wisdom tooth before planning an extraction. Standard dental X-rays provide useful information about the tooth and surrounding bone. However, these images are two-dimensional, so overlapping structures can sometimes make it difficult to determine how close the roots are to the nerve.
If additional information is needed, your dentist may recommend a cone beam computed tomography (CBCT) scan.
Cone Beam Computed Tomography (CBCT)
A CBCT scan creates detailed three-dimensional images of the teeth and jawbone. It helps your dental team examine the shape and position of the wisdom tooth roots in relation to the nerve canal.
This scan can provide information about:
- The direction and shape of the tooth roots.
- The position of the nerve canal in relation to the roots.
- The surrounding jawbone and nearby structures.
- Whether a different surgical approach may help reduce the risk of nerve injury.
A CBCT scan is not necessary for every wisdom tooth extraction. Your dentist will recommend it when the additional information is likely to help with treatment planning.
How Dental Teams Reduce Risks During Complex Wisdom Tooth Extractions
Once your dentist understands the position of the tooth and nerve, they can plan the procedure based on your individual needs. The goal is to remove the tooth safely while limiting unnecessary pressure on the surrounding bone and tissues.
1. Dividing the Tooth Into Smaller Sections
For some impacted wisdom teeth, removing the entire tooth at once may put extra pressure on the surrounding structures. Instead, the dentist may divide the tooth into smaller sections and remove them separately.
This technique can make it easier to remove the tooth through a smaller opening. It may also reduce the force needed during surgery, depending on the tooth’s position and root shape.
2. Using Appropriate Surgical Instruments
Dentists use specialised instruments designed for controlled and careful tooth removal. The choice of instruments depends on the tooth’s position, the surrounding bone, and the surgical plan.
In selected cases, specialised bone-cutting instruments may help the dentist work precisely around delicate structures. Your dental team will choose the techniques that are appropriate for your situation.
3. Considering a Coronectomy
When a lower wisdom tooth’s roots are very close to the inferior alveolar nerve, your dentist or oral surgeon may discuss a procedure called a coronectomy.
During a coronectomy, the dentist removes the crown, or visible top portion, of the wisdom tooth while intentionally leaving the roots in place. This approach may reduce the risk of nerve injury in carefully selected cases compared with removing the entire tooth.
A coronectomy is not suitable for every patient. For example, infection involving the roots or certain other dental conditions may make this approach inappropriate. The remaining roots also need monitoring because they can sometimes move over time or cause further problems.
Your dentist will explain the potential benefits, limitations, and follow-up requirements before recommending this treatment.
What to Expect During Treatment and Recovery
Your comfort and safety are important throughout the procedure. Local anaesthesia is commonly used to numb the area, so you should not feel sharp pain during the extraction. You may still notice pressure or movement. Sedation may also be available when appropriate.
After surgery, following your dentist’s instructions can help support healing and reduce the chance of complications.
- Manage swelling: Apply a cold pack to the outside of your cheek for short periods during the first 24 hours, as advised by your dentist.
- Protect the blood clot: Rest after surgery and avoid smoking, using a straw, or forceful spitting during the initial healing period.
- Choose soft foods: Eat foods that are easy to chew and gradually return to your usual diet as your mouth heals.
- Keep your mouth clean: Follow your dentist’s instructions for brushing and rinsing, avoiding the surgical area.
- Take medication as directed: Use recommended pain relief or other prescribed medication according to your dental team’s instructions.

Frequently Asked Questions
How can I tell if my wisdom tooth is close to a nerve?
You usually cannot determine this from symptoms alone. Your dentist can examine the tooth and review dental X-rays.
What is the main risk of removing a wisdom tooth near a nerve?
The main concern is nerve irritation or injury, which can cause numbness, tingling, or altered sensation in the lower lip, chin, or, depending on the nerve involved, the tongue.
Is a coronectomy safer than a complete wisdom tooth extraction?
For selected lower wisdom teeth with roots close to the inferior alveolar nerve, a coronectomy may reduce the risk of nerve injury. However, it is not appropriate for every case and may require follow-up monitoring.
How long does recovery take after a complex wisdom tooth extraction?
Many people begin to feel better within several days, and the gums often heal substantially over one to two weeks. Deeper bone healing takes longer. Recovery time varies according to the complexity of the procedure and the individual’s health.
