Sensitive teeth 1.5 years after genioplasty when touching the mandible. What can be causing this?

sorry to hear that you’re in discomfort. The x-rays are very helpful. The chin cut and the plate looks very good. I don’t know the exact reason that you are having sensitivity. It could be that the incision may be irritating the gumline or too close to the gumline. This may be best evaluated by your family dentist.
I hope this is helpful..

Good Morning SreenathNair,I hope this response finds you in good health. From what I can gather you are having quite severe pain throughout and tenderness on palpation of your genioplasty scar region. From the images I can see the location of the end plates seems approximated close to the roots of the teeth. That could be the source of your pain. Since it has been over a year now - the nerve roots should have reformed enough to have an alternative pain point having had developed. The treatment for this is medical and via massage mostly. A quick review with your operating surgeon would be the best thing to start off as well. Although an image is a great starting point , I would recommend a video consultation / in person consultation with a board certified Aesthetic Plastic surgeon to take this forward and thoroughly answer your query.
