Rapid breathing

Im creating a new thread to hopefully get quicker replies. I posted the video with my chinchillas buckie making crazy sounds. We went to his normal vet today and he said hethought there was a good chance the vocalizing and such was him responding to pain associated with his teeth and the points on them. I was planning to make an appt this week anyway because it was time for his dental filing and such. He has made those squeaks before because of tooth pain....but this time i thought i heard some congestion. His nose whistled a little for instance. The vet today and evet yeaterday both said his lungs are clear. Today he was sedated and the vet did alot of trimming and filing. He was expected to be pretty sore. He had a shot of baytril yesterday by the evet because i didnt want to risk it and today we got orbax because of the sores his teeth made in his mouth.

My question is....if his lungs are clear, he has no discharge of any kind, could rapid breathing now be because his mouth is sore and hes hurty? I hand fed him but didnt have to force him at all. He is pretty exhausted but he did sneak out of his cage to quickly for me to stop and ran around the room a minute. But im still just really worried and considering taking him to the evet again. They dont know alot but my vet said i could have them call him. Thoughts?
