    Groundhogs and Other Animals with Interesting Teeth

    In honor of Groundhog Day and Punxsutawney Phil, Delta Dental is filling you in on some facts about groundhogs… and their teeth.
    Groundhogs have 18 chewing teeth, as well as four chisel-shaped incisors. Their two upper incisors constantly grow—about 1/16 of an inch every week! So groundhogs must constantly gnaw on leaves, trees, grass and roots to keep the growth in check.

    Without a shadow of a doubt, groundhogs have some interesting pearly whites. But they can’t hog all the limelight. Here are several other animals with unique sets of teeth.

    GIRAFFE
    When it comes to number of teeth, giraffes and humans are neck and neck. We both have 32 teeth! As for the giraffe’s 20-inch tongue… well, that’s a different story.

    ALLIGATOR
    Alligators have between 74 and 80 teeth in their mouth at a time, but as their teeth wear down, new ones constantly replace them. A single alligator can go through as many as 3,000 teeth in one lifetime! Jaw-dropping, we know.

    HORSE
    You can estimate the age of a young horse based on its number of developed teeth. Typically by age five, they have a full set. You can trust our word, or learn it straight from their mouth.

    NARWHAL
    Narwhals live in Arctic waters around Greenland, Canada and Russia. You may recognize a narwhal from the long, hornlike tusk protruding from its head. But did you know that this tusk is actually an overgrown tooth?

    BLUE WHALE
    Whale now. This mammal doesn’t even have teeth. Instead, the blue whale has a structure called a baleen plate. Shaped like a comb, the bristles of the baleen let water pass through while trapping prey. Once caught, the whale brings in the food with its massive tongue.
