How do you get saliva gland stones?

Saliva: Xerostomia means dry mouth secondary to certain rheumatological conditions.

Calcuum: Salivary stones are usually small calcium stones that firm in the salivary duct. Most will past them self, sucking sugarless lemon drop or something that increases salivary flow can help more them along . Sometime a ENT may have to use a instrument to go into a duct and remove the stone and on rare occasions surgery.

Mineral Accumulation: Salivary stones are just like gall stones or kidney stones. They form over time from excess minerals which aren't removed properly. Think of the process as similar to a pearl which forms around a grain of sand over time. They're pretty common and don't generally cause too many problems. But they can be uncomfortable and lead to serious issues. Sometimes they have to be removed.
