4.5 to 5.5+ Years

4.5 Years

The enamel on the fifth tooth has worn away, and the dentine is now wider than the enamel on both the fourth and fifth teeth. The last tooth still maintains enamel wider than the dentine, since it hasn't worn away as much as the previous teeth.

5.5+ Years

All cheek teeth are beginning to show heavy signs of wear, and aging at this point becomes very difficult. In all teeth, the dentine is wider than the enamel. Only a small amount of enamel will remain on the third and fourth teeth. Cusps are dulled and teeth appear much more flat. Older deer will have dentine showing prominently when viewed from the top. All deer experiencing these tooth characteristics are lumped together in a 5+ year old category.
