Our vet has specialized training in dentistry, and he does a great job. I understand the reluctance to sedate, however I think sedation is a helpful tool for many horses. I HATE going to the dentist and especially the feeling, sound and smell of the drill, even though I understand what is happening to me and why it is important! My horse gets anxious easily, and there is no real way I can get him used to what he must go through once year when his teeth are floated. I feel it is much less stressful for him, not to mention safer to sedate him, and the vet can do a really good job.
