I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear that this happened.
You should read the contract before either of you talk to the dentist, because they could try to use clauses within it to avoid paying. It's not a defense that your husband can't read, because the law says that a person who signs a contract has read, understood, and agreed with everything in it. You need to know what language is in there that they might try to use against you.
With that said, when you pay someone to do work for you, there is an implied covenant that they will do it correctly. If the teeth do not fit, they need to fix them or refund enough of your money that someone else can. They can't make you pay more for a more expensive item because they breached the contract. If they will not fix the teeth, you can sue them for the cost of having another dentist do so, or for the cost of getting the correct dentures from another dentist. If you prefer to avoid going to court, it sometimes helps to send a letter, via certified mail, giving them one chance to return the money. If you are not a lawyer, you cannot represent your husband. You can take dictation for a letter if he tells you what to say, but he needs to be the one to sign it, and the letter should be from him. Otherwise, a local attorney can draft a letter from you.
