Wrangler's birth date is 5/8/2006. These two pictures were taken on 1/25/2011, putting him a bit over 4 1/2 years old. This is his left side and we can see that his upper corner incisor or I/3 is newly emerging from his gum line. The lower corner incisor is still his 'baby tooth' or deciduous tooth.
On the right side of his mouth you can see more of the erupting upper corner incisor or I 3/ . That the corresponding lower tooth is still his baby tooth is quite apparent: whiter, smaller and a distinct neck at the gum line.
Reviewing the tooth eruption chart from my previous post, note that Wrangler is on schedule with his teeth. The corner incisors are expected to erupt at 4.5 years of age.
Look at the photos again, paying attention to the intermediate incisors or I 2/2; note that the left teeth are smooth across the chewing surface (occlusial surface) indicating that they are 'in wear' and are actually 'level' at this time. Now look closely at the surfaces of the right I 2/2, the roughness indicates that the teeth have just recently become 'in wear' and it will be almost 6 months before they are 'level'.
One more tooth to note, on the right lower gum, behind his incisors, you can see his brown little canine tooth. These are common in male horses, not as common in mares.
Now go take a peak at your horse's incisors, have fun with teeth!
