About 2 days ago, I was riding my horse in an open field when he spooked and ran off bucking. I bailed because I was afraid he was going to slam into a fence or a tree. Apparently he got tangled in the reins as he was running off, because they were broken when I found him and his mouth was bleeding. I was riding him in a jointed Segunda bit, which has an upside-down "U" shaped port with sharp points on the edges of the port (pictured below). Today, I went out and looked in his mouth, and I saw that he had two bad cuts: one one the left side of his tongue, and one on the left gum where the bit sits. The cuts weren't bleeding, but the one on his tongue was almost an inch long. He wasn't sore at all, and I rode him today in the same bit (with very light hands!!) without problems. He is also eating normally. Does this mean it has already healed? If so, will he always have a scar? If not, what can I do to make it heal faster? Should I ride him in a hackamore until it does? Thanks.
