All pigs are born with teeth, which are used for eating and as weapons if necessary. Piglets are born with baby teeth, and their permanent teeth grow in around 1 year of age.
Pigs are born with incisors and canines, and these teeth eventually grow molars and premolars. Pigs' canines sharpen through the friction of other teeth and tend to be very sharp and dangerous. Pigs typically use their molars, which become irregularly formed over time, to crush their food before ingesting. Pigs are omnivores, which means they eat both plants and animals, and need their canines and molars to chew their food and eat.
