Although Twi’lek had ordinary teeth like Humans, male Twi’leks used to file their teeth to make them more pointy and sharp. According to their legends, for men, these sharp teeth were mainly a symbol of power that would also help them to survive. It would not be wrong to say that centuries of enslaving foreign influence had made them adopt such measures, not to mention that Twi’leks were also a primitive specie of the Outer Rims.
