Fact: The Teeth of Mice Never Stop Growing.
Wisdom teeth are notorious for the pain they cause us when they grow.
Compared to mice though, we are still infinitely better off. The teeth of mice keep on growing. If mice don’t do anything about their teeth, they might lose
the ability to close their mouths or eat properly.
Mice prevent teeth overgrowth by frequently gnawing on things. This is the main reason why
mice like to gnaw on hard objects that are not necessarily edible. It keeps their teeth short and sharp.
