Two of my rabbits have had their front teeth taken out due to them not lining up properly or wearing down. Was either that or have them trimmed every three months which I thought would just stress them out too much and can cause infections in the long run. They both cope perfectly fine without those teeth although they look kinda funny when they open their mouths. All I need to do for them now is cut any veg up into bite size peices for them instead of give it whole. They still eat all the plants and grass they used to in the garden with no difficulties and it doesn't hinder them at all in any way. I think I'd advice having this done for most rabbits whose front teeth aren't lined up properly rather than keep having them trimmed and risking infection or stress. Maybe this little lionhead could benefit from it if his teeth are an ongoing problem.
