Let’s try a little experiment. If you bring your chin to your chest, you will notice that your lower jaw will automatically move forwards.
This is exactly what happens with your horse when you ask him to go nicely on the bit, his lower jaw will move slightly forward.
One of the more common problems we come across in a horse’s mouth is the formation of hooks. This means that part of the first molars of the upper jaw and part of the last molars of the lower jaw are raised due to wear and tear from eating. You could imagine a horse would struggle to bring his lower jaw forward when it is blocked by hooks on the first molars of the upper jaw (see picture).
This problem can be very easily solved by rasping the teeth, and this will make it a lot more comfortable for your horse to go on the bridle and make for a happier ride.
Another reason why it is important to get your horses’ teeth checked!
