My husband is an equine dentist. After spending about $300 in tools, he finally got the "miniature" supplies a few months ago. Last week, he cut out Big Man's wolf teeth, and floated his teeth, and I'm not sure exactly what else. It got gross looking, when he cut out the wolf teeth, and I couldn't handle it, so I went inside.
He did say that doing a mini's teeth is a huge pain in the rear end. I didn't ask why, I just figured that it was because they were so much smaller. He did nearly fall over when he opened his mouth, and there were these HUGE teeth in that little mouth. He's still bewildered at how all of his teeth are going to fit in there, when they all come in.
He had to rig Big Man up in our "big horse" stock, had him crosstied & such. (Big Man did not think the teeth fixing was such a hot idea....he threw a pretty big fit at first)
Hubby did a good job, though. That evening, Big Man was eating his grain and he didn't drop any!!!!. We bitted him up and ground drove him the next morning, no soreness at all. He didn't fight the bit, or throw his head around. It really helped him a lot.
