I go to an NHS dentist, and I have to say, I like her. The place is no frills, but the bill is really reasonable. The dentist I used to go to back home in NY was a fortune, and while sometimes the extras are nice, the bills are not.
The only problem I have is that the appointments are short, so it does take a few appointments to get what one appointment at home would have covered. That said, I'm covered under bands of treatment, so despite all these appointments, it doesn't change the bill.
Also, I really like my dentist. I need an awful lot of work done, and she's doing her best to avoid the more painful procedures (root canal) when she can.
