Salivary Glands Disorders

The salivary glands have the ability to produce saliva that keeps your mouth moist, helps protect your teeth from rapid decay, and helps you to digest food.

Moreover, they are relatively small and are present around your mouth, lips, and cheeks.

There are a number of diseases that can affect your salivary glands.

These can range from cancerous tumors to Sjogren’s syndrome. While some conditions go away with the use of antibiotics, other conditions require serious treatment, including surgery.

Let’s discuss the causes of salivary gland disorders in detail.

Causes of Salivary Glands Disorder

There are 3 paired salivary glands in your oral cavity. These are the parotid, submandibular and sublingual glands.

They are responsible for producing saliva, however, if they are blocked, is one of the most common sources of problems.

These blocked glands can lead to more painful symptoms.

Sialolithiasis and Sialadentis

Sialolithiasis and sialadenitis can occur in your salivary glands, and these are as follows:

On the other hand, Sialolithiasis occurs when you have stones made of calcium form in the salivary glands.

These stones can block the glands and that can either partially or completely block the flow of saliva.

On the other hand, sialadenitis is an infection involving a salivary gland.

Most of the time, it results from stones blocking the gland.

Staph or strep bacteria can cause it and older adults and children are more prone to getting this infection.

Sjogren’s Syndrome

This is another common salivary gland disorder and occurs when the white blood cells in your bloodstream target the healthy cells of the salivary glands.

This condition affects women with autoimmune disorders like lupus.


Flue virus, mumps, echovirus, Coxsackie virus, or cytomegalovirus are some of the types of viruses that can affect your salivary glands.

Cancerous and Noncancerous Tumors

Tumors may develop in the glands as well, however, they are very rare. Noncancerous cells that can affect the parotid glands include pleomorphic adenomas and Warthi’s tumors.

However, benign pleomorphic adenomas can grow in the submandibular glands and the minor glands but is rare.

Symptoms of Salivary Glands Disorders

The symptoms of sialolithiasis are a painful lump under your tongue and pain that increases while you eat.

Sialadenitis symptoms are a lump in your cheek, pus that drains into your mouth, foul-smelling pus, and fever.

Moreover, cysts that grow in your salivary glands can cause yellow mucus, difficulty eating, speaking, and swallowing.


Viral infections like mumps can cause fever, muscles aches, joint pain, swelling on both sides of your face, and headache.

The symptoms of Sjorgen’s syndrome are dry mouth, dry eyes, tooth decay, sores, joint pain or swelling, dry cough, fatigue, swollen salivary glands, and frequent infections.

Moreover, they will take a Dental X-ray of the affected area to pinpoint the obstruction.

A head and neck surgeon can use these X-rays to administer anesthesia to numb the salivary gland opening and free any blockage.

Additionally, a biopsy can remove salivary gland tissue to aid in diagnosis.

This is particularly crucial if your doctor suspects that you have an autoimmune disorder that affects your salivary glands.

Treatment Options

Mumps: Mumps can cause infection of the testicles in males that can, later on, cause problems with fertility.
