The sensation to all lower teeth is primarily provided by which nerve?

The sensation to all lower teeth is primarily provided by the inferior dental nerve. This nerve is a branch of the mandibular division of the trigeminal nerve (cranial nerve V). It enters the mandible through the mandibular foramen and runs within the mandible, giving off branches that innervate all the lower teeth, including the molars, premolars, canines, and incisors.

The inferior dental nerve is responsible for transmitting sensory information, such as pain, touch, and temperature, from the lower teeth to the central nervous system. This is crucial for dental procedures and understanding dental anatomy. The importance of this nerve is highlighted in dental practices, particularly in administering local anesthesia for lower tooth procedures, which targets this nerve for effective pain control.

Other nerves mentioned, such as the greater palatine nerve and nasopalatine nerve, are involved in providing sensation to the hard palate and anterior maxillary teeth, respectively, while the long buccal nerve supplies sensation to the buccal mucosa and mandibular molars but does not provide innervation to the teeth directly.
