should be checked every 6 months. Horses teeth erupt from
the gums throughout their lives. The upper and lower arcades (rows
of teeth) do not line up evenly, so the teeth don't wear down evenly
on all surfaces. The outer edge of the upper arcade doesn't get worn
down and can form sharp points or edges. The same thing occurs with
the inner edge of the lower arcade. This can cause lacerations and
abrasions on the upper gums and on the tongue, thus making chewing
painful. It can also make having a bit in the mouth uncomfortable.
"Floating" or using rasps to take off the sharp edges and the tall
ramps will prevent problems with eating, weight loss, biting, and
behavioral problems. Power tools are also available.
