Bruxism
Bruxism (teeth grinding) is a commonly observed problem in horses, and is often a sign of a physical or psychological discomfort. Sudden onset of bruxism should be investigated in relation to clinical problems, as this is likely to be due to pain. Longer term bruxism can lead to other problems such as wear of the molars and other oral problems that could lead to pain and/or feeding issues.
