Sialadenitis occurs most often in people with a combination of the following:
- Older age (past 50)
- Debilitated from illness or dehydrated
- Dry mouth (xerostomia)
Saliva flow can be reduced in people who are sick or recovering from surgery, or in certain elderly people. A stone (sialolith) or a kink in the duct also can diminish saliva flow. Diseases that reduce salivary flow (such as Sjögren's syndrome) may lead to sialadenitis. People having treatment for cancer also are susceptible to this infection.
Once fluid balance has been restored, your dentist may recommend sugarless sour candies or gum. They can stimulate your body to produce more saliva.
If the infection is not improving, you may need surgery to open and drain the gland. If the sialadenitis is caused by a stone in the duct, the stone may need to be removed by surgery.
