  2. The Importance of Determining the Age of Horses Uses: • Validate advertised age when buying • Confirming age when racing or showing • Feeding for proper nutrition at various life stages

  3. Aging by Teeth • An art that requires skill and experience • Very old method of aging horses • Error increases with horse’s age • Becomes an educated guess after horse is older than 14 years • Stabled horses tend to appear younger (less tooth wear) • Pastured horses tend to appear older (more tooth wear)

  4. Maxilla Wolf Tooth (when present) Canines Incisors Molars Mandible Premolars Equine Tooth Structure Horses have 24 temporary teeth and 42 permanent teeth

  5. Central Incisors (also pincers or nippers) Intermediate Incisors Corner Incisors Equine Tooth Structure Age is determined using the 12 front teeth (incisors)

  6. Mouthing a Horse for Age In Real Life: Hold the tongue out and to the side with your hand. This restraint provides an unobstructed view and is not painful to the horse.

  7. Tooth EmergenceTemporary Teeth (Baby Teeth) Temporary pincers: Birth - 10 days Temporary intermediates: 4 – 6 weeks Temporary corners: 6– 10 months

  8. Canine teeth appear: 4-5 years Permanent corners: 4 ½ years Permanent intermediates: 3 ½ years Permanent pincers: 2 ½ years Tooth EmergencePermanent Teeth 6 years old

  9. Tooth Wear As horses age, “cups” disappear from incisors 15 years old 6 years old As horses age, teeth become more triangular-shaped

  10. Galvayne’s Groove A mark on the upper corner incisors that appears and disappears in a predictable pattern as horses age Usually appears around the age of 10 years.

  11. Galvayne’s Groove A mark on the upper corner incisors that appears and disappears in a predictable pattern as horses age Groove is usually half way down at age 15

  12. Galvayne’s Groove A mark on the upper corner incisors that appears and disappears in a predictable pattern as horses age By age 20 the groove usually extends the full length of the tooth

  13. Galvayne’s Groove A mark on the upper corner incisors that appears and disappears in a predictable pattern as horses age Groove begins to recede around age 21

  14. Galvayne’s Groove A mark on the upper corner incisors that appears and disappears in a predictable pattern as horses age Groove is halfway gone by age 25 and disappears completely around age 30.

  15. Aging Using Teeth Determine the most likely age for the following horse • 7 years • 14 years • 21 years • 28 years Wear – No Cups
