As I am considering the same, you may be interested in this letter I had from a friend on the subject.:
I went to Budapest with Hungarian British Medical Services and went out paying for my own flight and hotel. They picked me up and took me to the practice and I was very impressed. For your interest on this visit I also visited 2 other practices and they were all as good - up to date equipment and very clean and tidy premises and surgeries. I chose BHMS because they all spoke English and they changed the TV in Reception to English
There is a 3 month period without teeth after extraction so the gums can heal before implants can be put in.
Dr Halasz performed the actual implants with other dental surgeons working with him. They were all very good.
Their web site is
http://www.cosmeticdentistry.hu/ and if you have a look at this you will find all the information about both London Dental Practice and Hungary. The London Dental opened because they are able to do consultations for Budapest providing both quotations and/or treatment. I went there for annual checkups which one must have to keep the guarantees on the implants/teeth. Unlike UK they offer a range of Implants - in honesty I cannot actually see what can go wrong except for infection in gum.
London Dental also put the healing screws in about 2 weeks before the actual crowns/bridge was fitted
There is a button on the website for Prices. If you get the UK to quote you then know what you are looking at saving.
Chill Blaski was the UK representative who I also had contact with by telephone. I actually spoke direct with Budapest to arrange things so I could do flights. I would fly out on Sunday and met at airport by their driver and taken to Opera Gardens Hotel which is also within the BHMS group and you get a very good discount - they also know all about dental eating requirements.
