Should I Remove My Wisdom Tooth? Risks and Concerns - Dentistry

More Info

---

Deciding whether to remove a wisdom tooth, particularly one that is close to the nerve, is a significant decision that requires careful consideration of various factors, including potential risks and benefits. Your concerns about the proximity of the tooth's roots to the nerve are valid and warrant a thorough discussion.

Firstly, it's important to understand that wisdom teeth, or third molars, often become problematic due to their position in the mouth. They may become impacted, meaning they do not fully emerge through the gums, which can lead to pain, swelling, and infection. In your case, the previous swelling you experienced indicates that there may have been some level of inflammation or infection associated with the tooth.

Regarding your question about whether the wisdom tooth will continue to grow and potentially move away from the nerve, it's unlikely that the tooth will shift significantly in position. Wisdom teeth typically stop developing once they have fully erupted, and if they are impacted, they may not erupt at all. Therefore, if the tooth is already close to the nerve, it is unlikely that it will grow further away from it.

The primary concern with wisdom teeth that are close to the inferior alveolar nerve (the nerve that runs along the lower jaw) is the risk of nerve injury during extraction. This injury can lead to temporary or, in rare cases, permanent numbness or tingling in the lower lip, chin, or tongue. The likelihood of experiencing nerve damage during the extraction depends on several factors, including the position of the tooth, the skill of the oral surgeon, and the complexity of the extraction.

Studies suggest that the risk of permanent nerve damage is relatively low, estimated to be around 1-2% for lower wisdom teeth extractions. However, the risk can be higher if the roots of the tooth are deeply embedded in the bone or if they are in direct contact with the nerve. Temporary numbness is more common and may last for weeks or months after the procedure, but most patients recover fully.

To mitigate these risks, it is crucial to have a detailed discussion with your oral surgeon or dentist. They may recommend imaging studies, such as a cone beam CT scan, to get a clearer view of the tooth's position relative to the nerve. This information can help them plan the extraction more effectively and minimize the risk of complications.

If you decide to proceed with the extraction, your oral surgeon will likely take precautions, such as using sedation or local anesthesia, to ensure your comfort during the procedure. They may also discuss the possibility of using techniques that can reduce the risk of nerve injury.

In conclusion, the decision to remove your wisdom tooth should be made in consultation with a qualified dental professional who can assess your specific situation. They will consider the risks and benefits of extraction, your overall dental health, and any potential complications. If you have concerns about the procedure, do not hesitate to express them; a good dentist will take the time to address your worries and help you make an informed decision. Remember, maintaining good oral health is essential, and addressing problematic wisdom teeth can prevent future complications.
