Trigeminal neurolgia. Or anything else?

My wife is getting pain on right side near ear and eye. Pain is severe on right side of the face and it is continuous, there is not a second that pain was not there. Painkillers used to give relief for some time and later again it starts. Pain is continuous and it is always there and it is from 3 weeks. Only few hours od the day there was less headache and all the other time continuous headache spreading from right top side of the face till upper teeth. But most of the times it is pointed pain concentrated at right top temple. It is pointed and will not go away for a second also. Left side is fine. There was not a time that the headache was not there. Earlier there were no symptoms like these. 3 months back a tooth for which root canal treatment is done was extracted. This is lower tooth. Is this trigeminal neurolgia? Or anything else?
