I have had it done on mine several about 4 years ago?
The gal did a nice job from what I can tell and two years ago I had an equine dentist check their teeth, at that point he said they could go another 6 months before needing to be done again. Of course there are other factors that contribute like eating habits but I thought 2+ years was pretty good compared to the power float that a vet did previously that the NB dentist has to fix as I was having issues.
Again, like you said, regardless of the method it depends on the job done.
I DON'T LEAD 'EM AND FEED 'EM, I RIDE 'EM AND SLIDE 'EM.
