Neurologist Please. Advise and help.

I have had serious teeth irritation and sensations which led to dental flap surgery 2 months back. I consulted 3 doctors before proceeding with the surgery for second thoughts. Post surgery, irritation is somewhat relieved but not sensations. Sensations comes across teeths. Although i had neck spasm along with teeth issues, i neglected neck, thought that could be a different thing. After the surgery, i still have sensations to cold, hot or spicy items. Difficult to drink even cold/hot water. I have used all types of desensitized gel, mouthwash and toothpastes with no breakthrough. I have noticed that neck spasm happens along with the uneasiness with the teeth. Also i showed up a orthopedic doctor with an xray, thinking this could be from neck/spine. But xray was neat, there is no irregularities. My gut feeling is that this could be Neurology related. Please advise and help.
