Your salivary glands produce saliva, which keeps your mouth moist, helps protect your teeth from rapid decay, and helps you to digest your food. The salivary glands are relatively small, and they’re around the inner linings of your mouth, lips, and cheeks.
A number of diseases can affect your salivary glands. These range from cancerous tumors to Sjogren’s syndrome. While some go away with time or antibiotics, others require more serious treatments, including surgery.
You have three paired salivary glands called the parotid, submandibular, and sublingual glands. They are responsible for producing saliva. The most common cause of salivary gland problems is blocked salivary glands, which can cause painful symptoms.
Sialolithiasis and sialadenitis are problems that can occur in the salivary glands. Sialolithiasis occurs when stones made of calcium form in the salivary glands. These stones can block the glands, which can partially or completely stop the flow of saliva.
Sialadenitis (or sialoadenitis) is an infection involving a salivary gland. It often results from stones blocking the gland. Staph or strep bacteria can cause this infection. Older adults and infants are most likely to develop this condition.
Sjogren’s syndrome is another common salivary gland disorder. It occurs when white blood cells target healthy cells in moisture-producing glands, such as the salivary, sweat, and oil glands. This condition most commonly affects women with autoimmune disorders, such as lupus.
Viruses also can affect the salivary glands. These include:
Cancerous and noncancerous tumors may develop in the salivary glands as well. Cancerous tumors of the salivary glands are rare. They typically occur between ages 50 and 60, according to Cedars-Sinai .
Noncancerous tumors that can affect the parotid glands include pleomorphic adenomas and Warthin’s tumors. Benign pleomorphic adenomas can also grow in the submandibular gland and the minor salivary glands, but this is rare.
The symptoms of sialolithiasis include:
Sialadenitis symptoms include:
Cysts that grow in your salivary glands can cause:
Viral infections in the salivary glands, such as mumps, can cause:
The symptoms of Sjogren’s syndrome include:
If you have diabetes or alcoholism, you may also have swelling in the salivary glands.
If you notice the following symptoms, see your doctor:
Your doctor will recommend testing based on your medical history and a physical exam. However, some cases are quite obvious from the history and physical exam. In such cases, diagnostic tests may not be necessary.
Your doctor may want to see the blockage to diagnose a salivary gland obstruction. Taking a dental X-ray of the affected area can help to pinpoint the obstruction. A head and neck surgeon can then use anesthesia to numb the salivary gland opening and free any blockage.
If your doctor needs to finely target the salivary glands, an MRI or CT scan can provide more in-depth images. Also, a biopsy to remove salivary gland tissue can aid in diagnosis, particularly if your doctor suspects you may have an autoimmune disorder that affects your salivary glands.
Treatment for salivary gland disorders depends on the disease type and how advanced it is.
For example, if you have a mass in your salivary gland, your doctor may recommend surgery to remove the mass or the gland itself. If the mass is cancerous, you may need radiation treatments to kill off cancerous cells. These treatments won’t typically start until your body has had time to heal. This is typically four to six weeks after surgery.
Radiation treatments to the neck can cause dry mouth, which can be uncomfortable and affect your digestion. Your doctor may recommend drinking more fluids and avoiding foods high in sodium.
If the salivary gland mass isn’t cancerous, radiation may not be required. A mass that doesn’t cause symptoms may be treated with conservative measures. This includes special mouthwashes to relieve dry mouth.
Antibiotics can treat bacterial infections.
Taking good care of your teeth is vital to successful salivary gland treatment. Brushing and flossing your teeth at least twice a day can help prevent salivary gland disorders and tooth decay. You can keep your mouth moist by rinsing with a mixture of 1/2 teaspoon of salt in 1 cup of water.
