There are four major glands that produce saliva. The parotid glands are in front of and slightly below the ear on both sides. The submandibular glands are underneath the jaw on both sides. In addition there are hundreds of tiny minor salivary glands throughout the mouth and throat. The major glands can occasionally get infected and swell and need antibiotics, sometimes they can develop stones that are similar to kidney stones, theoretically. Tumors, which are mostly benign but occasionally cancerous, may also develop.
When lumps of the salivary gland develop, a diagnostic workup will be completed after which, medical treatments and surgical options (when indicated) will be discussed.
