What are my rights here? I lost my dental insurance due to non payment?

I didn't find out untill 2 months after going to the dentist that it was cancelled, and nobody told the dentest office. Metlife sent me notices that everything was paid for. Can they come back later, and say I owe them

You have the right to pay the bill. Yes, they, the dentist, can come after you for the amount you owe them - and they will, eventually.
