Implants can cost several grand apiece
Also it is surgery, they place the metal into the gum then it needs to grow in for a few months, then you go back and they open the gum and screw in the teeth!
My niece is going through all this at the moment. She broke some teeth several years ago when she fainted in the street and fell on her face - because it was an accident cased by a medical event ie a faint, she got full NHS funding and it isn't costing a penny, but it has been painful and invasive. First they tried to save the broken teeth, but that didn't work, then they removed them (the two front uppers, poor girl) and she's had a plate ever since......not nice for a pretty girl in her late teens/early 20s
I'd have to be rich and brave to go down the implant route and I am neither of those things
I believe it can be a lot cheaper abroad though, I know a lot of people go to Hungary and such places from the UK for cosmetic type dental procedures these days.......
