Salivitis is an infection of the parotid salivary glands caused by bacteria or viruses, fungi, or allergies. Manifestations of acute swelling of the gland, pain and swelling when eating.

Salivary gland inflammation occurs when the salivary glands or salivary tubes become infected with bacteria or viruses. An infection can lead to decreased salivation due to a blockage or inflammation of the salivary tubes.

Mumps can be confused with salivary gland disease. Mumps can lead to infertility, while simple parotitis can cause facial deformities.
