Excessive Transverse Ridges
Excessive Transverse Ridges are a series of washboard like ridges that occur across the grinding surface of the molar arcades. Excessive transverse ridges can restrict the movement of the temporal mandibular joint, forcing the horse to open its mouth to get anterior/posterior and lateral movement of the lower jaw. This may sound unimportant but the correct function and movement of the mandible and temporal mandibular joint is vital for the horse. While most would agree that normal ridging is important in the grinding function of the teeth, if these ridges become too exaggerated they will need to be reduced to a normal level.
