Yesterday I had two big fillings done on my molars (no anesthetic), and a light clean and descale, and it cost me £145, private, for 40 minutes work. I paid £170 for another big tooth repair a few weeks ago that required two sessions following the original check up. That is over three weeks income for me but it repairs two broken teeth and a cavity.
I have no problem with a reasonable cost for the work as the dentist has to train, and run a surgery, and maintain standards, and ensure that people who don't look after their teeth properly still have teeth to not look after.
I am firmly of the belief that essential services are worth the cost. It is just a shame that some 'more essential' services are not paid as much as others.
For the OP
The standard of work expected in the UK and abroad might be different, as might the acceptable local standard for teeth and what the local economy will stand. The local cost of living might also have a large impact on the cost of providing that service.
Maybe your team would have thought the cost would have been worth it.
