Can dentist send me bills half a year later claiming my insurance didn't cover all costs? - dentist cover letters

I had some work done and paid for dental care for all equilibria in the dental office. The staement leaving a balance amount of $ 0
I recently received a bill from the dentist, six months later made this work and stated that I owe them money, and that the invoices are overdue. Although this is the first letter I of them!
I pulled out of the state 2 months ago and also switched insurance and I have a new employer. Can they still come after me?
