Many people have impacted wisdom teeth, but not everyone decides to have surgery immediately, especially when the impacted tooth is close to a nerve. Concerns about numbness, recovery time, and post-surgical risks often follow. This article will help explain what it means when an impacted tooth is near a nerve and what examinations are needed before surgery.
How risky is it to be near a nerve?
The nerve involved is the inferior alveolar nerve, which is responsible for sensation in the lower lip and chin area. If the impacted tooth is close to or touching this area, it may increase the risk of nerve irritation after surgery. However, this does not mean that every case will have complications, and most symptoms, if they occur, are usually temporary.
How do doctors assess the tooth’s position?
Because the impacted tooth and nerve are inside the bone and cannot be seen with the naked eye, imaging is required, including both 2D and 3D images.
- 2D images help show the direction of the tooth and approximate position
- 3D images help show whether the tooth is above, near, beside, or below the nerve, as well as the depth and amount of surrounding bone
These details are important for surgical planning and risk reduction.
How do 3D images help in wisdom tooth surgery?
Information from 3D images is not just illustrative but provides structural data that helps the medical team make more accurate decisions, such as:
- Whether the tooth needs to be sectioned before removal
- The safest direction for the incision
- Areas to avoid to prevent nerve damage
With complete information, patients receive clearer explanations about risks, expected outcomes, and surgical methods.
The role of the CT Bright machine in treating impacted teeth
For cases where the impacted tooth is deeply embedded or close to a nerve, doctors often consider imaging with the CT Bright machine, which is specifically designed for 3D dental imaging. It provides structural details around the tooth that 2D images cannot show, such as:
- Distance from the nerve
- Shape and curvature of the tooth roots
- Thickness of the surrounding bone
This information helps improve planning accuracy, reduce unnecessary risks, and allows patients to make decisions based on real data rather than worry.
When is the best time to remove impacted teeth?
The decision is not based solely on “pain or no pain” but should consider:
- Whether the impacted tooth has started to cause problems
- Whether it may affect adjacent teeth
- Whether there are plans for orthodontics or jaw surgery
- The patient’s age (younger patients usually recover faster)
In some cases, doctors recommend surgery before problems arise because the bone condition is more favorable and the risk of future complications is reduced.
Pre-surgical evaluation is therefore an important step that helps reduce risks and increase confidence in treatment, especially in cases with complex tooth positions. Wisdom tooth surgery, particularly when the tooth is near a nerve, should be based on complete information about the position, depth, and relationship to the nerve before making a decision.
The Dental Center at Phyathai Nawamin Hospital offers 3D imaging with the CT Bright machine to assess these details, along with care from a multidisciplinary team of dental specialists, including oral and maxillofacial surgery, implant dentistry, and orthodontics. They work together to evaluate and provide appropriate treatment recommendations. Interested patients can schedule a pre-surgical evaluation at the Dental Center, 2nd floor, Phyathai Nawamin Hospital.
