I have a wonderful equine dentist-I have never seen him sedate, and we have happy horses thru the whole thing. He is closer to Rochester-$75 for a float. I don't remember how much extractions are-it has been years since one of mine needed any. Just need to plan LOTS of extra time-he is a "chatter".
Some of my friends use vets tho-I refer to it as "spring cleaning".
they sedate and power float and clean sheathes...... As I recall about $150/horse. THey share the farm call cost.
