    I have a horse with an underbite. Does anyone out there know if this is a problem or not?

    Definition - Lower incisors protrude in the front of upper incisors.
    Etiology - Hereditary - Horse is born with under bite. Developmental - Ramps on lower premolars can cause lower jaw to shift forward resulting in an under bite.
    Resulting Problems - Prevents horse from chewing freely side to side resulting in improper and excessive molar wear. Ramps, transverse ridges, wave complexes and sheared molar table angles will become more severe as horse is forced to chew incorrectly over time. Can also cause severe discomfort with the bit. Can result in TMJ pain.
    Solution - Reduce length of lower incisors. Correct corresponding molar abnormalities.
