The mandibular canal is a narrow passageway located within the lower jawbone, or mandible. It houses the inferior alveolar nerve and blood vessels, which supply sensation and blood to the lower teeth and chin. This canal runs from the back of the jaw to the front, typically beneath the roots of the teeth. Understanding the anatomy of the mandibular canal is crucial for dental procedures, especially during tooth extractions or dental implants. Damage to the structures within the canal can lead to complications, such as numbness or pain, making knowledge of its location essential for dental professionals.
