What is salivary gland infection?

Salivary glands make saliva, or spit. An infection in these glands can make the glands swell and hurt.

An infection can happen when bacteria gets into the gland. This is more common in people who have diabetes, poor tooth care, or stones in these glands. Bacteria can build up and cause an infection if you don't get enough fluids. It can also happen if the flow of saliva gets blocked by a small stone in the gland. A virus can also cause an infection.

Your care depends on the cause. If the problem is caused by bacteria, your doctor may prescribe antibiotics.

Home treatment may help. You can drink more fluids or suck on sugar-free lemon drops to increase the flow of saliva.

• If your doctor prescribed antibiotics, take them as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.
• Take an over-the-counter pain medicine if needed, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Be safe with medicines. Read and follow all instructions on the label.
• Do not take two or more pain medicines at the same time unless the doctor told you to. Many pain medicines have acetaminophen, which is Tylenol. Too much acetaminophen (Tylenol) can be harmful.
• Drink plenty of fluids. If you have kidney, heart, or liver disease and have to limit fluids, talk with your doctor before you increase the amount of fluids you drink.
• Put an ice or heat pack (whichever feels better) on the swollen jaw for 10 to 20 minutes at a time. Put a thin cloth between the ice or heat pack and your skin.
• Suck on ice chips or ice treats such as sugar-free flavored ice pops. Eat soft foods that do not have to be chewed much.
• Use sugar-free gum or candies such as lemon drops. They increase saliva.
• Avoid over-the-counter medicines that can give you a dry mouth. These medicines include antihistamines, such as diphenhydramine (Benadryl) or chlorpheniramine (Chlor-Trimeton).
• Gently massage the infected gland.
