How was your experience?

Very good, having so much treatment in a few days cured my fear of dentists.

The bone graft and implants were done by Dr Dr Attila Kaman who I
presume owns the place, a second dentist did extraction and root canal
work, a third filed the teeth down to "pegs" for crowns and took
impressions and fitted them all.

They seem to have moved to London from Budapest.

And how did you find a good dentist over there?

Google! at the time it didn't feel any more random than picking a
dentist out of yellow pages. I discussed it back and forth over email
with them for a few weeks before booking in.
