Thanks Foxbat
And Joan and Roberto.
The dentist is for me, so I appreciate the recommendations.
I have no qualms about visiting a Spanish speaking dentist - the one I usually see in Granada is fine for general work, but from previous experience, I don't think that the practice is up to doing the complicated work I need done this time.
Also, as I already have extensive notes in English on what needs to be done, I would like to know that the dentist completely understands what's required - hence I would have more confidence in a dentist who speaks English, but if I feel he or she is good, then I'm sure I can get by with my limited dental Spanish and diagrams.
So, Joan and Roberto, I'll contact those dentists when I get back to Spain - Thanks.
And Faro, I would be interested in your dentist too.
