If it's slight, it's mostly cosmetic, but horses with more "action" in their stride, or with really severe cases, can interfere which can cause splints and a greater potential for lameness. Trimming more frequently and making sure the foot is well balanced every time (which I'm guessing you already do, along with other responsible horse owners) can help alleviate the problem.
