My 8 month old little one has a baby tooth stuck in the back of his mouth... its hanging by a THREAD and it looks rotten! I took him to the vet and she looked at it and said to wait about 2 weeks... and if it doesn't come out, she'll pull it. But his breath is REALLY starting to stink

Is there anyway to speed along the process? He isn't chewing on the chewies i've been providing for him. Blahhhh.
