Quality of expensive dental work in Germany

OK, here's my predicament: about 30 years ago, when I first came to Germany, I had a dental bridge stuck into my mouth. Seven teeth, glued to four front teeth which are whittled down to stubs. Literally, stuck tight; I have not had any problems for the past 30 years.
Two months ago I went to my German dentist who took an X-ray and noticed that one of the whittled down teeth is dead. She said the whole bridge needs replacing. That will cost a couple thousand in Germany no doubt. I am only covered for 70% in Germany, which I get as Beihilfe. I don't have a price estimate yet, but I'm betting I might have to pay about 2000 Euros, which I don't have.
I returned to the UK (where I now live, been here eight years) and investigated the NHS. Turns out I would only have to pay only £195 for NHS treatment. I did not tell the dentist here about the dead tooth; the dentist here took an x ray and I assumed she'd notice it. She didn't. She filled a cavity and that was it. I did not speak up.
SO, how good can the NHS treatment be, if she did not notice?
I am going to India for two months; I've heard that you can get good dental treatment in India. Any experience here? Any advice?

You can get fantastic dental treatment in India. However, the majority of dentists are probably lousy. I would get a recommendation first. If your friends and family don't know one, the place to ask (or search the archive) is www.indiamike.com.
