The tooth enamel on the molars is in absolute measure the thickest of any known ape, averaging in three different molars, and over on the tongue-side (lingual) cusps of an upper molar. This has attracted comparisons with the extinct "Paranthropus" hominins, which had extremely large molars and thick enamel for their size. However, in relation to the tooth's size, enamel thickness for "Gigantopithecus" overlaps with that of several other living and extinct apes. Like orangutans and potentially all pongines (though unlike African apes) the "Gigantopithecus" molar had a large and flat (tabular) grinding surface, with an even enamel surface, and short dentine horns (the areas of the dentine layer which project upwards into the top enamel layer). The molars are the most hypsodont (where the enamel extends beyond the gums) of any ape.
