Dental Help

Hi

I have a 4 year old male chinchilla, Ollie. Last month, I noticed that his breath smelled terrible, he wasn't eating, and he was drooling. I took him to the vet. A dental procedure was done and the vet found that Ollie's teeth were very overgrown and he had one very long point which cut into his cheek. His gums were quite inflamed too. All teeth and his points were burred down. We were feeding him critical care and giving him pain medication and antibiotics after. Now it's been a little over 1 month. He is eating some hay and pellets. But I've noticed that he is dropping a lot of his pellets, just like before when his teeth were overgrown. He's not chewing on his sticks like he normally did. I'm starting to get worried. I'm wondering if I need to take him back to the vet again or if healing after a dental procedure takes time before they are "back to normal."He is running on his wheel and around the room like nothing is wrong though. I haven't noticed any bad smell from his mouth but I've noticed that his mouth area is a bit wet sometimes.
