TEETHING BUMPS (ERUPTION CYSTS)
Location: These bumps are found on the lower jaw, approximately halfway between the nose and throatlatch. They commonly appear on both sides at the same time, although one side could be bigger than the other. What it is: These bumps appear in young horses (typically 2 to 4 years old) and are caused by pressure from permanent teeth as they push out the deciduous or “baby teeth.” Look and feel: Teething bumps are usually about the size of a walnut or smaller, and feel very hard and bony. Should you worry: If your horse is in the correct age range and the bumps aren’t painful when you squeeze them, they shouldn’t be a problem. In some horses, the baby teeth or “caps” will be retained (difficult to push out), and these teething bumps can become enlarged and painful due to excessive pressure. Your vet may recommend removing the stubborn caps to relieve pressure and allow permanent teeth to move in.
