equine dentist coming ... what questions should I ask?

Jubilee's getting her teeth floated today. The first time since I've gotten her, which was in October. She doesn't have a problem with her teeth (at least I don't think). They've been looked over by my trainer and she said they look good, she eats well and puts on weight and isn't sore when riding. But she is almost 18 and having a float will problem be good for her. I've never even seen a horse have its teeth floated before. What should I expect? BTW, she's not going to be sedated. And what kind of questions should I ask the dentist about her teeth??

Thanks!

Ooo just enjoy it! Its really cool! Ask to see the teeth and look for the points against the sides of her mouth. Ask to feel it. Touch the tounge and play with your horse as much as possible while its sedated. I also suggest if you don't like drills try not to watch. But its nothing like our dentists. Much cooler and they are way more sedated. :)

I've only seen it done once. The vet had a rasp and just rasped where the sharp points were. It made a weird noise lol the pony didn't care at all - he's a great little guy!
