evidence: What’s less obvious is how Carrey’s choppers are central to that maximalism. Ever present amid the limb flailing, back arching, and facial contortions is an expressive use of upper teeth, which jut out in a slight overbite that the actor pushes to its limits whenever he goes full wackadoo. They appear as a motif across Carrey’s quintessential characters. The otherworldly trickster he plays in The Mask isn’t just distinct for an engorged face with lime-green skin but also for its abyssal mouth that contains an unnatural set of cartoonish oversize teeth. Lloyd Christmas, the sweet idiot he plays in Dumb and Dumber, is iconic for both his bowl cut and a chipped front tooth that’s emphasized when pressed into a stupid, beaming smile. [...] Just as the late Peter Lorre’s bulging eyes remain his most enduring feature, teeth will be Carrey’s long after he’s gone. There’s even a mythological quality to the way teeth link to his story. One fun fact about Dumb and Dumber’s Lloyd Christmas is that his broken front tooth isn’t actually fake. Carrey had already chipped it due to a childhood mishap, and while he had it capped as an adult, the actor opted to revert it for the comedy of the character. "De Niro gains weight. I file my teeth off," he told Entertainment Weekly in 1994. If that’s not evidence of the greatest teeth actor who ever lived, I don’t know what is.
