Symptoms:

Symptoms vary, depending on the specific type of salivary gland disorder:

• Sialolithiasis – The most common symptom is a painful lump, usually in the floor of the mouth. Pain may worsen during eating because the stone blocks the flow of saliva.
• Sialadenitis – Symptoms may include a tender, painful lump in the cheek or under the chin; a foul-tasting discharge of pus from the duct into the mouth; and in severe cases, fever, chills and malaise (a generally sick feeling).
• Viral infections – The first symptoms may include fever, headache, muscle aches, joint pain, poor appetite and malaise. These are followed by swelling in the parotid glands, usually on both sides of the face, in the cheeks and below the ears, and difficulty opening the mouth.
• Cysts – A cyst causes a painless lump that sometimes grows large enough to interfere with eating, speaking, chewing or swallowing. Mucoceles can burst, releasing a straw-colored liquid.
• Tumors – A slow-growing lump – sometimes painful – is the most common symptom of both cancerous and noncancerous salivary gland tumors. This lump may be found in the cheek, under the chin, on the tongue or on the roof of the mouth.
• Sjgren's syndrome – Sjgren's syndrome causes dry mouth, tooth decay, frequent mouth infections, mouth sores, swelling of the salivary glands, sialoliths and recurrent salivary gland infections. It also causes dry eyes, which may lead to chronic eye infections, corneal ulcers and vision loss. There may also be muscle pain, joint pain, malnutrition, weight loss and many other symptoms.
• Sialadenosis – This condition typically causes painless swelling of the parotid glands on both sides of the face, in the cheeks and below the ears.
