When experiencing dental problems, horses may show signs of pain, or they may not display any outward signs at all. This is why regular dental exams are vital. If you notice your horse dropping feed from its mouth (quidding), foul mouth odor, nasal swelling or discharge, facial swelling, excessive salivation, traces of blood in the mouth, undigested feed in their manure, or other general changes, such as a change in body condition, poor performance, head tilting, or bridal resistance, contact your veterinarian. 

Common dental problems include:

• Broken or lost teeth
• Formation of sharp enamel points or hooks, which may cause lacerations inside the mouth
• Infected teeth and gums
• Over-worn teeth
• Periodontal disease 
• Retained baby teeth
• Uncomfortable or intrusive wolf teeth
