I agree. My Rickie had a very complex extraction last year (it was done by a board certified dental specialist) and the cost was in the range of $500 for one tooth (a large molar, the roots were hooked, near the blood supply, etc., it was a long and tricky job). I was very glad she was doing the work, rather than a general practitioner.
That said, I agree that xrays are a must beforehand, and, if it looks like a difficult extraction, I'd look into having a specialist do it. If it looks straightforward, then up to you. JMO.
