The dental system is like the doctors,they claim a certain amount for the work they do.If the patient pays,they pay a percentage of what the actual work would cost,if you don't have to pay anything at all,the dentist claims that as well as the standard NHS cost.They pay their lab bills separately and the materials they use.
Now if the dentist chooses to be a cheapo and use the cheapest of everything,they still claim the same amount as if they used the best.
They also get paid for however many patients they have,regardless of if they see the patient that year.So long as the patient is registered to them,its money in the bank!
Also they get a set fee per child,again,regardless of if they see the child.
So the dentist may not actually make the dentures themselves,but they are responsible for paying the lab.
Loads of paperwork from what I remember.
And as you can tell,it scarred me for life!
