How do rabbits file down their continuously growing teeth?

Rabbits file down their continuously growing teeth primarily through the process of chewing. As herbivores, rabbits have a diet that consists mainly of fibrous materials like hay, grass, and veggies. The act of chewing these materials provides the necessary abrasion to wear down their teeth, which grow continuously throughout their lives.

This natural behavior helps prevent dental issues that can occur if their teeth become overgrown, leading to potential health problems. Chewing also helps in maintaining the correct alignment and size of the teeth, essential for their overall well-being.

While other options may have some impact on dental wear, they do not play a primary role in the way rabbits efficiently manage their tooth growth. Rubbing against surfaces and gnawing on wood can provide some wear, but the act of chewing fibrous food is the most significant contributor to maintaining healthy teeth.
