I think that work would depend on the degree that the Trigeminal nerves are effected. It would depend on pain control and management well as the type of medications being used. I think that more people suffer with this condition than is reported. I suffered for years, had all my upper teeth removed except 5 front, had multiply sinus surgeries and many maxillary procedures done. To later be told it was not necessary and did make matters worse. Through 30 years of this I continued to work, but fortunately my work is flexible and understanding.
