I visited Dr. Gregory recently. I think his attitude is really reserved. He doesn't express himself in a very reassuring way. He retreated a prior root canal in a very hasty way. I paid a lot of money for very average service. He didn't explain things very clearly. I'm not very impressed with him. He recommended I take certain medicine (ibuprofen) for an indeterminate amount of time. Yet he couldn't promise me that I would get better after taking all that medication. Not very encouraging.
