Galvayne's Groove

I've always thought myself fairly accurate with telling a horses age by their teeth... but now I'm not so sure...

I have a book that shows pictures of the lower incisors and the upper centrals and intermediates, and today I decided, just for the heck of it, to check out my 20 y/o mare's teeth and compare to it, as the book shows horses teeth at 2, 3, 4, 5, 6, 7, 10, 15 and 20 years of age.

According to the book, my twenty year old mare is really between 12 and 15 years old... judging by both Galvayne's Groove and the dental stars on the lower centrals...

I'm confused here... Can their teeth really be off by as much as five to seven years? Because I know my mare is twenty...

GGroove isn't 100% accurate. A mare's groove indicated she was about 13, yet everything else, slope of teeth, tilted pelvis, etc. indicated she was closer to 30.

Lol. When I compared my mares teeth to the chart I have, I kinda mentally freaked, lol.

Don't forget though, in addition to the groove, look to see the angle of the teeth, how 'long in the tooth' they are.

Dental aging is always a ballpark estimate. I guess it also depends on the horse's lifestyle and whether or not they have any vices, especially cribbing.

Had a vet age my grade Paint as 11ish. But I had already owned him by that time 13 years and had he was well broke when I bought him. I aged him by teeth and my time with him as 20ish.

So that can be off quite a bit, and too, there are some horse traders that will file down teeth to make them appear younger.

Horses make me a better person.

It always use to be that ant horse over the age of eight was classified as 'aged' because only up to eight years can their teeth be accurate
