One yr old not talking

My son had a doctors appt today ( thought he had a ear infection) but turns out he's teething extremely bad, anyway my 14 month old isn't talking. Which is fine but he was talking at 10 months old like momma dada, no and yea. He completely stopped which is my concern. We recently moved from NC to SC. His pediatrician said it could be stress from the move, went husband and I work with him on words and reading to him at night. His doctor said if he doesn't start talking in a few months then it's time to go to the next level.. which he didn't go into details but when he points i tell him what it is a couple of times and then let him touch it. Does anybody have anything else they recommend to do?
