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.
(I learned this the other day when my wife thought rabbits were rodents and we ended up looking it up.)
