Toothache? Trigeminal neuralgia?


Hello Doctor: A few days ago, I asked a question here, and thank you for your response.
This week, I visited a neurologist, who prescribed me Trileptal for a week (0.5 tablets after each meal).
I have been taking the medication for three days, but the tooth pain has not improved.
Does the ineffectiveness of the medication mean that I do not have trigeminal neuralgia? It is said that trigeminal neuralgia is more common in middle-aged and older adults, and since I am young, I probably wouldn't have it, right? Should I see a dentist now? (I have already lost confidence in dentists >"<)

If the medication provides only short-term relief or only partially alleviates the pain, it still indicates that the medication is effective; adjustments in dosage or the addition of other medications may be necessary.
However, if there is no effect at all, it may suggest that it is not primary trigeminal neuralgia, and further examinations such as an MRI may be needed to identify other potential causes of the pain.

Toothache and trigeminal neuralgia can often present similarly, but they stem from different underlying issues. Trigeminal neuralgia is characterized by sudden, severe facial pain that can be triggered by simple activities such as chewing, speaking, or even touching the face. It typically affects older adults, but it can occur in younger individuals as well, especially if there are underlying conditions affecting the trigeminal nerve.

Given your situation, where you have been prescribed Trileptal (Oxcarbazepine) for three days without improvement, it raises a few considerations. First, it is important to understand that while Trileptal is effective for many patients with trigeminal neuralgia, it may not work for everyone, and the absence of relief does not definitively rule out the condition. The effectiveness of the medication can vary based on individual responses, and it may take time to find the right dosage or medication that works for you.

Since you mentioned that you are young, it is indeed less common for trigeminal neuralgia to occur at your age, but it is not impossible. Other factors, such as multiple sclerosis or vascular compression of the trigeminal nerve, could also contribute to your symptoms. Therefore, it is crucial to consider all potential causes of your pain.

If your toothache persists despite the medication, it may be worthwhile to revisit a dentist or seek a second opinion. Dental issues such as cavities, gum disease, or even issues related to previous dental work (like fillings or crowns) can cause significant pain that might mimic trigeminal neuralgia. A thorough dental examination, including X-rays, could help identify any underlying dental problems that may have been overlooked.

Additionally, if you have already seen a dentist and are not satisfied with their assessment, consider consulting an oral surgeon or an endodontist (a specialist in root canal treatment). They can provide a more detailed evaluation of your dental health and determine if there are any issues that require intervention.

In summary, while your symptoms may suggest trigeminal neuralgia, the lack of response to medication and your age warrant further investigation. It is advisable to consult with a dental professional to rule out any dental causes of your pain. If dental evaluations continue to show no issues, you may need to follow up with your neurologist to discuss your symptoms further and explore other potential diagnoses or treatments. Remember, effective communication with your healthcare providers is key to finding the right diagnosis and treatment plan.
