If you are in South Herts, Martin Wilkinson is excellent or alternatively Roger from Ingatestone Saddlery also covers that area. I had my vet do my horse's teeth having had a bad experience with an equine dentist in the area.
Someone i know had a dentist called Matt come out but i can't remember what company he was part of, he covers herts/Bucks etc and was really good any ideas?
Damian Greenshields. I've only used him once but won't hesitate to use him again. My whole yard uses him and he was very gentle and patient with my Horse who had never seen a dentist and one of the youngsters having his teeth done for the frist time. Highly recomended.
