Hey there.

I have not used any of these dentists but i know a little about them from my dentist John Rees(amazing they're all called John!)

John Roberts and John Rees know each other pretty well and he consulted Mr Roberts with my dental issues. Mainly my allergies. I know Mr Roberts is quite expensive and that as a replacement he does not use methacrylate as it causes a lot of issues itself in people, myself included. Mr Roberts uses Admira which he's said he's had great results with. So if you go with Mr Roberts this will be his first choice of dental material. He is a very empathetic dentist apparently who himself suffered from mercury poisoning.

Mr Ahearne i've heard is also a very very good dentist who will test you for suitable replacements. His prices are fantastic. If i lived closer to that area i'd be there for sure but simply the financial cost of getting there puts me off. I think that dentist is family run too.

..and finally you can always go and see my dentist John Rees if you're in the midlands area. What i like about John is that he genuinely wants to help me get sorted. He will even buy in the product you want him to use on you if you pay him for the materials (He has my Admira waiting for me) i just got to get the funds to have it put in.

Good luck and i hope this helps.
