MMA is a traumatic sport. I see a lot of the top fighters in the UFC have good teeth which seems surprising to me. I got injured in a short sparring session. (because of a very bad mouthpiece but nonetheless) That's none of the full-force fighting in the UFC. Yet I don't think a lot of fighters had problems with teeth. Do you know fighters who reportedly suffered from such things? All I remember is Couture's loss to Machida.
