My buck ( 8.5 yrs old ) seems to have too - long of teeth. His bottom front teeth are so long that they irritate his top lip, and it's now swollen - he is still eating and drinking, and when he courts a doe and flips his lip i see the red mark where they rub. He has a good bite, but is just over growing ???? What can be done for this ? Can you file/float teeth like you can in horses ? Thanks !!!
