Many different problems can prevent saliva from draining by inhibiting the function of the salivary glands or by blocking the ducts. These causes the salivary glands to swell.
Here are the common causes of swelling of the salivary gland:
One of the most common causes of swollen salivary glands is salivary stones. These stones are essentially crystallized deposits of saliva. These stones can sometimes block saliva flow, causing the salivary glands to swell.
Secondly, swelling of the salivary glands can also be caused by infections caused by various viruses and bacteria. Mumps is the most well-known example of these infections.
Thirdly, benign or malignant tumors can also cause swelling in the salivary gland.
Fourthly, cysts that are congenital or develop after infection or trauma can also cause swelling in the salivary glands.
Fifth, autoimmune diseases that cause the body to attack itself, such as Sjögren's syndrome, can also cause swelling of the salivary gland.
Therefore, treatment for swollen salivary glands varies depending on the cause. To determine the cause, an ear and nose examination is essential, followed by further tests to address the underlying cause.
