[4] Most species have as many as 22 tooth without having canines or anterior premolars. A niche, or diastema, happens concerning the incisors as well as the cheek teeth in many species. This allows rodents to suck in their cheeks or lips to protect their mouth and throat from wood shavings together with other inedible substance, discarding this waste from the edges of their mouths.[citation required] Chinchillas and guinea pigs have a high-fiber diet plan; their molars haven't any roots and increase continually like their incisors.[five]
