Why do people get the urge to bite things?

People may feel the urge to bite things due to a combination of sensory stimulation and stress relief. Biting can provide a tactile experience that engages the senses, offering comfort or satisfaction, especially in stressful situations. Additionally, this behavior is often instinctual, rooted in early developmental stages when infants explore the world through biting and mouthing objects. In adults, it can manifest as a coping mechanism for anxiety or frustration.
