Salivary Gland Stones: A Comprehensive Guide
Key Takeaways
Salivary gland stones form when minerals build up in the ducts that carry saliva to your mouth
The submandibular gland under the jaw is most commonly affected, followed by the parotid gland
Symptoms include pain and swelling that gets worse when eating or drinking
Most stones can be treated without surgery using conservative methods like massage and hydration
Small stones may pass on their own, while larger stones might need medical removal
Overview
Salivary gland stones, also called sialolithiasis, are small mineral deposits that form inside the ducts of your salivary glands. These glands make saliva to help you digest food and keep your mouth healthy. When stones block the flow of saliva, it causes pain and swelling.
This condition affects about 1 in 10,000 people each year. Men are twice as likely to develop salivary stones as women. The condition most often affects adults between 30 and 60 years old, though it can happen at any age.
Most salivary stones form in the submandibular gland, which sits under your jaw. About 80% of cases involve this gland. The parotid gland near your ear is the second most common location. While uncomfortable, salivary stones are not dangerous and rarely lead to serious complications.
Salivary stones are more common in warm climates where people may not drink enough water. They happen more often in people who already have other problems with their salivary glands. The good news is that most people get better quickly once they start treatment.
Symptoms & Signs
Salivary gland stones cause symptoms that typically come and go. The pain and swelling often get worse when you eat or drink because your mouth produces more saliva at these times.
Primary Symptoms
Pain and swelling in the affected gland that increases during meals
Dry mouth or reduced saliva flow on one side
Bad taste in your mouth from reduced saliva production
Difficulty opening your mouth when swelling is severe
Visible lump under your jaw or near your ear that may feel hard
When to Seek Care
You should see a healthcare provider if you have persistent pain or swelling in your salivary glands. Get medical attention sooner if the swelling spreads to your neck or if you develop a fever, as these could indicate infection. Some people also notice that the pain goes away and comes back, which can happen when a stone partially blocks the duct and then moves slightly. If you can see or feel a hard bump in your mouth that doesn't go away in a few days, this is another good reason to call your doctor.
When to Seek Immediate Care
Contact a healthcare provider immediately if you have severe swelling, difficulty swallowing, or signs of infection like fever and chills.
Causes & Risk Factors
Salivary stones form when calcium and other minerals crystallize in your saliva ducts. Several factors can increase the likelihood of stone formation.
Dehydration is one of the main causes because it makes your saliva thicker and more concentrated. This thick saliva moves more slowly through the ducts, giving minerals time to settle and form stones. Poor oral hygiene can also contribute by allowing bacteria to build up in your mouth. Understanding allergies symptoms, causes, and management options can help you identify if allergic reactions are affecting your saliva production.
Certain medications that reduce saliva production can increase your risk. Some medical conditions that affect your immune system may also make stones more likely to form. Illnesses that make you lose a lot of fluids, like vomiting or diarrhea, can also lead to salivary stones. Some people inherit genes that make them more likely to get stones in their body, including in their salivary glands.

Diagnosis
Your healthcare provider will start by asking about your symptoms and examining your mouth and neck. They will feel for swelling and may try to express saliva from the affected gland.
Medical History & Physical Examination
During the exam, your provider will ask when your symptoms started and what makes them better or worse. They will check both sides of your mouth and neck to compare. The provider may gently massage the gland to see if they can feel a stone or if saliva flows normally. They will also look inside your mouth for signs of blockage or infection.
Diagnostic Testing
Ultrasound to see the stone and check for blockages in the duct
CT scan to get detailed images of larger stones and surrounding tissue
Sialography using contrast dye to map the salivary ducts and locate blockages
MRI in some cases to get clearer images of soft tissue around the glands
Treatment Options
Treatment aims to remove the blockage and restore normal saliva flow. Most cases can be managed without surgery using simple techniques.
Conservative Treatments
Hydration therapy by drinking extra water to thin your saliva and help flush out small stones
Warm compresses applied to the outside of the affected gland to reduce swelling and encourage saliva flow
Gland massage performed several times daily to help move stones through the duct naturally
Sialogogues like sour candies or lemon drops that stimulate saliva production and flow
Advanced Treatments
Lithotripsy using shock waves to break up larger stones into smaller pieces that can pass naturally
Endoscopic removal where a tiny scope is used to locate and remove stones through the natural duct opening
Surgical removal for very large stones or when other treatments fail, though this is rarely needed
Most people feel better within one to two weeks of starting conservative treatment. Your doctor may give you antibiotics if an infection develops. Pain medication can help keep you comfortable while the stone moves or is being removed.
Living with the Condition
Most people recover completely from salivary stones with proper treatment. The key is maintaining good habits to prevent new stones from forming.
Daily Management Strategies
Stay well-hydrated by drinking at least 8 glasses of water daily. Practice good oral hygiene by brushing twice daily and using an antibacterial mouthwash. Gently massage your salivary glands for a few minutes each day to keep saliva flowing smoothly. Avoid medications that reduce saliva production when possible, and talk to your doctor about alternatives if needed. Similar to how understanding rare types of anemia requires ongoing monitoring, salivary gland health benefits from regular attention.
Keep track of when your symptoms get better or worse to help your doctor monitor your progress. Many people find it helpful to eat soft foods while recovering from salivary stones. Avoiding very hot foods and drinks can also reduce pain during the healing process.
Exercise & Movement
Regular physical activity helps maintain overall health and proper hydration levels. Gentle neck exercises can improve circulation to the salivary glands. Avoid activities that might cause whiplash or neck injuries, as trauma to the neck area could affect your salivary glands.
Prevention
Drink plenty of water throughout the day to keep your saliva thin and flowing
Maintain excellent oral hygiene with regular brushing, flossing, and mouthwash use
Stimulate saliva flow by chewing sugar-free gum or sucking on sugar-free candies
Avoid smoking as it reduces saliva production and increases infection risk
Keep a water bottle with you so you can drink water throughout the day. Staying hydrated is the most important thing you can do to prevent future stones. Limiting caffeinated drinks like soda and coffee can also help since they can dehydrate you.
Frequently Asked Questions
Yes, stones can return if you don't maintain good hydration and oral hygiene. Following prevention strategies significantly reduces the risk of recurrence.
Small stones may pass within a few days to weeks with proper hydration and massage. Larger stones typically need medical treatment to be removed.
While both involve mineral deposits, they form in different parts of the body. Having one type doesn't necessarily mean you'll get the other, though some people may be prone to both.
Salivary stones are uncommon in children but can occur. The treatment approach is similar to adults, focusing on hydration and conservative management when possible.
Most salivary stones can be treated without surgery. Only large stones or those that don't respond to conservative treatment may require surgical removal.
