Hi there,
First time really posting, and doing so for a friend. Apologies for the long post, but the details are all necessary.
So.... I have a friend, who recently had severe toothache, and as he wasn't registered with a dentist, had to make an emergency appointment where they took him on privately. This is an NHS dentist, but of course they do private work also.
When he told me the pain he was experiencing, from my personal experience I said it may likely need a root canal, but as it was one of his back teeth, he may prefer to just save the money and get the tooth extracted.
He goes to the emergency appointment on Wednesday, at a cost of £135 (£90 for it being emergency, £45 for the actual appointment), where he is told root canal, followed by a crown, extraction or hygienist (?!?!?!) Are his options to solve the problem. He's in agony and is sat there while the dentist faffs around what he wants to do. Friend's response is "you're supposed to be the professional, wwyd?" Dentist initially says extraction, which friend expected and is obviously cheaper than root canal, so he agrees. Dentist numbs him and is preparing to do the work when the dentist suddenly says "I think we can, and should save the tooth (STT)" friend is shocked and obviously numb and lying there helpless. Dentist calls a colleague in, he then gets told go for x-rays, so he does, despite being numb (!!), and then takes a seat again. The 2 dentists are sat there, friend says looking like they're plotting, and eventually come out with "we should really try to STT"
Friend is shocked, but agrees, despite the huge cost increase as his thoughts are, 'well they know best'
Then the dentist says "come back on Saturday to start your root canal" (!!!!) So friend is incredibly annoyed, as he's been numbed for no reason, and they still haven't done anything about the pain. He asks about this, and they give him a leaflet about taking paracetamol and ibuprofen correctly. He is told to come back Saturday at 10am to start the root canal.
Saturday comes, he goes for his appointment and is taken to a hygienist first (£100), then they start the root canal (£350) and it is mentioned that the tooth is a bit wobbly, but it "should be ok" 
He is then told come back on the following Wednesday.
Wednesday comes, and he goes back, is numbed again and the dentist then says "oh the tooth is still wobbly, that should have cleared up by now"
At this point, I would like to add that there has been No medication prescribed and therefore anything that needed "clearing up" would not do so magically of its own accord!
So the dentist calls a colleague in again, the some plotting colleague, who then says "I don't think we can STT"
Friend is gobsmacked and infuriated and says "just take the damn thing out now, like I wanted in the first place!" The dentist does it and when it's all over says "we could have STT if the infection had cleared up" so my friend asks him why he wasn't given any antibiotics then? Dentist says, "no, the pus and bleeding should have gone and we don't give antibiotics for that"
(since when?!?!)
Friend is then charged £120 for tooth extraction and starts asking to be refunded for the unnecessary costs he has incurred. Dentist refuses and says it was all necessary.
So now, my AIBU.... AIBU to think that my friend has been ripped off and basically mistreated by this dentist, and that who starts a root canal, surely this is a procedure that is done in one appointment, and to expect that he should only have been charged for the inital emergency appointment and the eventual tooth extraction and refunded the rest for the unsuccessful and unnecessary treatment?! Also, if there was an infection, SURELY he should have been given antibiotics to clear this BEFORE any work was carried out?!
And if we are not BU, as I suspect, what can he do to get his money back and potentially sue for damages?!
If you've read this far, then thank you!!!
