Damage To Sensory Nerve After Wisdom Teeth Removal
Wisdom teeth removal is a common dental procedure that involves the extraction of four third molars found at the back of the mouth. While this procedure is generally safe, it can cause damage to the sensory nerve that runs through the jaw, leading to numbness and loss of sensation in the lower lip, tongue, and chin.
What is the Sensory Nerve?
The sensory nerve, also known as the inferior alveolar nerve, is responsible for providing sensation to the lower lip, chin, and tongue. It is located in the mandible, or lower jaw bone, and can be damaged during wisdom teeth removal if the roots of the teeth are too close to the nerve.
How Does Nerve Damage Occur?
Nerve damage can occur during wisdom teeth removal if the dentist or oral surgeon accidentally damages the nerve while extracting the teeth. In some cases, the nerve may be compressed or stretched during the procedure, leading to damage. The risk of nerve damage is higher in older patients, as the nerve may be more brittle and prone to injury.
Signs and Symptoms of Nerve Damage
The signs and symptoms of nerve damage after wisdom teeth removal include numbness or loss of sensation in the lower lip, chin, and tongue. Patients may also experience a tingling or burning sensation in the affected area, or difficulty speaking, eating, or drinking. In some cases, patients may also experience pain or discomfort in the affected area.
Treatment Options for Nerve Damage
If you experience nerve damage after wisdom teeth removal, it is important to seek treatment from a qualified dental professional. Treatment options may include medication to manage pain and inflammation, physical therapy to improve nerve function, or surgery to repair the damaged nerve. In some cases, the nerve may heal on its own over time.
Preventing Nerve Damage
The best way to prevent nerve damage during wisdom teeth removal is to choose an experienced and qualified dental professional. Your dentist or oral surgeon should carefully assess the position of your wisdom teeth and the location of the sensory nerve before the procedure to minimize the risk of damage. They may also use advanced imaging technology, such as panoramic x-rays or cone-beam computed tomography (CBCT), to visualize the nerve and surrounding structures.
Conclusion
While nerve damage after wisdom teeth removal is a rare complication, it is important to be aware of the signs and symptoms and to seek prompt treatment if you experience any numbness, tingling, or loss of sensation in the lower lip, chin, or tongue. By choosing an experienced and qualified dental professional and taking appropriate precautions, you can minimize the risk of nerve damage and ensure a safe and successful procedure.
