My son paid about £150 a couple of years back - to a dentist called Zoltan I think. He was most impressive and looked after our party of 5 very well. We all got cold drinks and even sat in the room with my son whilst he watched MTV on the overhead screen. I then asked about having mine done and he checked my teeth over to see if it would be OK. I had a slight gum infection and he said best not to at the moment. I offered to pay for his time and he said' Why? I haven't done anything.'
Once back in the UK I asked my own dentist and paid £300 for mine doing. However I now have a fitted gum shield so I can buy the same stuff cheaper on the net and 'top up' as required.
