This photo is of a 25 year old gelding that was having difficulty chewing his feed. You can see that he has a number of dental issues but the most obvious is a deep laceration in his cheek caused by a sharp enamel point. Also, many of the cheek teeth are wore to the gum line making it difficult to chew hay and other coarse feeds. And there were some fragmented molars that required extraction.
You just never know what you will find until you look!!
