Ok so over the weekend massive amounts of pain with my back tooth to the point where I had to go to the dentist today. This particular dentist I used to go to about 3 years ago but had a denplan scheme. So anyway in I trot they asked me to fill out a form as I havent been for awhile. No further questions asked about payment and before I know it 2 of them are carrying out the and root canal filling. Upon strolling down to reception I get hit with a bill for £417!! Part of me thinks I should have asked but was in so much pain it just didnt enter my head and part of me thinks they should have done the bloody work without checking!! Your thoughts please?
