Literally every rodent. Having teeth like that is the defining feature that distinguishes them from other similar types of mammals, such as lagomorphs (rabbits etc.), which have four top teeth.
Rodents (from Latin rodere, ‘to gnaw’) are mammals of the order Rodentia (/roʊˈdɛnʃə/ roh-DEN-shə), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws.

Mouth closed: cutest little critter
Opens mouth: 😳 wtf
Tbf this condition is shared by many humans as well, so we can add this to the list of excellent lemming metaphors
Basically any rodent(to my knowledge).

Maybe this is just a bad angle. Doesn’t look so bad in some other pics.
