I went the other day for my 6 month check up, been private since 2000 when I had denplan at my old work when I left the job, I liked the dentist so didn't bother trying to go NHS with the 12 month fookin wait...
Anyway, top and bottom X ray and a clean/polish was £75.
I felt robbed
But NHS is basically a BIG discount of that Jim

don't be worried, the worst they can do is rip all your teeth out
