Hi Michelle,
Glad to hear Patch has come through his op OK and is eating again.
If your vet wants to do conscious teeth clipping, the he will need is a pair of buccal pad separators which you can only get from Vedra at the CCT. Without these, he won't be able to keep Patch's mouth open properly. Then he needs to be able to wrap the pig, have suitable bone roungers and rasps for trimming / filing, and some training to make sure that he knows exactly what to do. So many vets don't really know what "normal" guinea pig teeth look like as they are all different, just like humans. One of the biggest mistakes made is that lower incisors are trimmed "because they are too long", when in fact they are designed to be longer than the top ones!
Training takes about 1-1.5 hours and the BAR notes are comprehensive. I showed one of my own vets how to do this, and she now does guinea pig dentals as part of the normal consulation - no anaesthetics or fuss, so much safter for the pig and cheaper for the humans! The nearst BAR people that do teeth are myself and Chris & Titch in Hastings.
Hope this helps, Chrissie & 11 Gorgeous Guineas
