Cause – Rubbing Of Sharp Teeth Against The Soft Tissue
Have you ever bit the inside of your cheek? The sore you feel with your tongue is a cheek ulcer. These are not caused by stress but from trauma from the sharp tooth.
In the horse, cheek and tongue ulcers develop when the sharp points rub against the soft tissue and rub away the outer layers. Depending upon the horse’s threshold of pain, these ulcers are either not noticed by the horse, or they cause him to violently object to the bit.
The treatment is to remove the offending sharp edges and, like your cheek, the ulcers will heal quickly.
