Never mind that, I can't believe any denture manufacturer would willingly use a type of plastic or metal that is dissolved by a mild water-soluble organic acid.
In fact, I don't even think there's any rigid plastic or workable metal that would dissolve in such conditions. At the risk of being shouted down by an ignorant mob, I'm going to stick my neck out and say I don't believe this story is entirely plausible.

I'll keep an ear open in the chippy,
for anyone requesting "absolutely no vinegar, else my teeth will melt."

Now if you stuck real teeth in vinegar for nearly a whole day, they WOULD dissolve.
You'd need something like hydrochloric acid in alcohol or acetone to do any chemical damage to dentures, even the cheap ones.

I think we should get in touch with guffguff's mum's dentist's laboratory of choice, since he has basically libelled them by claiming their products were knowingly sold while not being fit for purpose.
