Thanks heaps for this reply, Dr Deb, this has been such a learning experience on so many levels.
I opted for putting the tooth in water out near the back door so I can keep it topped up, it is looking cleaner on the outside already.
Re Little's diet, she hasn't had sweet feed or pony nuts while she has been with me, she has been getting sugar beet rinsed and soaked while her tooth socket is healing and all her hay soaked. She gets adlib grass hay with the Shetland herd usually. Chaff and Copra was the feed of choice but I have moved the herd over to chaff Meadow/Timothy/ Oaten and sugar beet as the quality of the copra was not good enough, I had found weeny stones in it that I blamed for the tooth issue!!
I brought her from a riding school and I can't imagine them feeding her sweetfeed but she was in another home prior to that.
Best Wishes
Judy and Little
