I wear dentures and have done for many years due to an accident in my 20s. I have always had NHS dentures and have found them very good, but last year they broke, my practice is part NHS part private one of these big companies, the dentist said they could not offer me a new pair but I could have a repair, which meant that I would be without my front upper teeth for 3 weeks, or I could pay private to the tune of £900 ( this is a partial set)and he showed me the dentures saying they are more flexible and it would be a better fit , his mother had a set blah blah . Tbh there is no difference, yes initially they seemed more flexible but honestly 12 months later you can't tell the difference. I was told by someone who until recently had worked in a dental practice and she said the 3 week wait for a repair is untrue and they can turn around repairs in 48 hours which I would have been happier with. although I don't see why I wouldn't have been eligible for a new set as I had them for a number of years. So I do feel they push you the private route for no good reason except they are forced by the company they work for.
