What Is a Galvayne's Groove?

It appears as a dark or brownish groove in the upper corner incisor teeth and is typically visible in horses around 10 years of age. However, various factors can affect the accuracy of age determination based on this groove alone.
- ▪The Galvayne's groove first appears at the gum line in horses about 10 years old.
- ▪By age 20, the groove should extend from the top to the bottom of the tooth.
- ▪After age 20, the groove begins to disappear, starting from the top.
