The submandibular gland is a salivary gland about the size of a plum that lies immediately below the lower jaw. Saliva drains from it through a tube that opens on the inside of the mouth under the tongue immediately behind the lower front teeth.
The most common reason for removing a submandibular gland is as a result of infection that occurs if the tubes that drain saliva become blocked. Blockages usually arise as a result of stones.
