The orange coloration in their teeth is not random. The coloring is caused by their enamel, which includes a pigment that consists of the mineral iron. This pigment is the cause of the orange color of the teeth. All of this ends up giving the teeth a chisel-like form that helps them greatly with gnawing.

What are rat teeth made of?
The upper and lower jaws each have a single pair of incisors that grow continuously through their lives. The front of each tooth is made from hard enamel, while the back is made of soft dentine. As the rodent gnaws, the incisors scrape at each other, and the dentine wears away faster than the enamel.
Why are Nutrias teeth red?
The coloring is caused by their enamel, which includes a pigment that consists of the mineral iron. This pigment is the cause of the orange color of the teeth. The iron in it gives the teeth a tougher and firmer texture, which enables the smoother portions in the back to grind down more rapidly.
