The form and function of microbat teeth differ as a result of the various diets these bats can have. Teeth are primarily designed to break down food; therefore, the shape of the teeth correlate to specific feeding behaviors.<ref>{{Cite journal |last=Evans |first=Alistair R. |date=2005-04-25 |title=Connecting morphology, function and tooth wear in microchiropterans: FUNCTIONAL DENTAL MORPHOLOGY IN MICROCHIROPTERANS |url=https://academic.oup.com/biolinnean/article-lookup/doi/10.1111/j.1095-8312.2005.00474.x |journal=Biological Journal of the Linnean Society |language=en |volume=85 |issue=1 |pages=81–96 |doi=10.1111/j.1095-8312.2005.00474.x}}</ref> In comparison to megabats which feed only on fruit and nectar, microbats illustrate a range of diets and have been classified as [[insectivore]]s, [[carnivore]]s, [[Hematophagy|sanguinivores]], [[frugivore]]s, and [[nectarivore]]s.<ref name=":3">{{cite book |last=Freeman |first=Patricia W. |chapter=Form, Function, and Evolution in Skulls and Teeth of Bats |year=1998 |title=Bat Biology and Conservation |editor1=Thomas H.

The diverse diets of microbats reflect having dentition, or cheek teeth, that display a morphology derived from dilambdodont teeth, which are characterized by a W-shaped ectoloph, or stylar shelf.<ref>{{cite web | last1=Wund | first1=Matthew | last2=Myers | first2=Phil | title=Chiroptera (bats) | website=Animal Diversity Web | date=2005-08-16 | url=https://animaldiversity.org/accounts/Chiroptera/ }}</ref> A W-shaped dilambdodont upper molar includes a metacone and paracone, which are located at the bottom of the “W”; while the rest of the “W” is formed by crests that run from the metacone and paracone to the cusps of the stylar self.

Microbats display differences between the size and shape of their canines and molars, in addition to having distinctive variations among their skull features that contribute to their ability to feed effectively. Frugivorous microbats have small stylar shelf areas, short molariform rows, and wide palates and faces. In addition to having wide faces, frugivorous microbats have short skulls, which place the teeth closer to the fulcrum of the jaw lever, allowing an increase in jaw strength.<ref>{{Cite journal |last=Freeman |first=Patricia W. |date=March 1988 |title=Frugivorous and animalivorous bats (Microchiroptera): dental and cranial adaptations |url=https://academic.oup.com/biolinnean/article-lookup/doi/10.1111/j.1095-8312.1988.tb00811.x |journal=Biological Journal of the Linnean Society |language=en |volume=33 |issue=3 |pages=249–272 |doi=10.1111/j.1095-8312.1988.tb00811.x}}</ref> Frugivorous microbats also possess a different pattern on their molars compared to carnivorous, insectivorous, nectarivorous, and sanguinivorous microbats.<ref name=":3" /> In contrast, insectivorous microbats are characterized by having larger, but fewer teeth, long canines, and shortened third upper molars; while carnivorous microbats have large upper molars. Generally, microbats that are insectivores, carnivores, and frugivores have large teeth and small palates; however, the opposite is true for microbats that are nectarivores. Though differences exist between the palate and teeth sizes of microbats, the proportion of the sizes of these two structures are maintained among microbats of various sizes.<ref name=":3" />
