Hi Nigel

I am not sure whether John uses a Galvometer or not so i cannot tell you for sure. His prices are expensive but he charges by the hour not by the number of fillings. So if you have large fillings it works out not so bad also. I think its £250 per hour. I am pretty sure he does biocompatibility testing but admits he knows someone who is far better at testing for it and will refer you to him. I think it's a place in Derbyshire. As for consultations i am not sure what John charges. I don't recall it being too expensive though as i'd remember!

If there is one thing i can urge you to do is that no matter what dentist you go to. I strongly suggest you dont have any product by 3M put in your mouth. They are all highly toxic and have given so many people including myself very serious reactions. Their range includes the Filtek brand which is very common amongst dentists who use white fillings.

Regards
Stuart
