A horse's lower jaw is more narrow than its upper jaw so the teeth on their upper jaw develop sharp points on the cheek side. On their lower jaw the sharp points develop on the tongue side. The vet is filling down those sharp edges.

For anyone wondering, this process is called “floating” a horse’s teeth. Keeps them from slicing their own tongues on their teeth.
