Have you ever noticed a sudden, painful swelling near your cheek or jaw and wondered what is going on? Let us explore sialadenitis!

Have you ever noticed a sudden swelling near your cheek or under your jaw that hurts when you touch it? Eating a meal can become very painful, and you might even develop a fever. Feeling worried when this happens to you is completely normal.

Today we will discuss a condition that causes this exact issue. In medical terms, this is known as an inflammation of your salivary glands, called sialadenitis.

What Are Salivary Glands and What Do They Do?

Simply put, your salivary glands are small organs inside your mouth that produce saliva. Saliva is much more than just simple water. Saliva is extremely important for your daily health.

When you eat food, saliva helps moisten it so you can swallow easily. Saliva also starts the digestive process right inside your mouth. Another vital role is protecting your teeth and gums from harmful germs and tooth decay.

Your mouth contains three main pairs of large salivary glands:

• Parotid glands: These are the largest salivary glands located in front of your ears on both cheeks. When people get mumps, these parotid glands are the ones that swell up.
• Submandibular glands: These sit inside your lower jaw, underneath the floor of your mouth.
• Sublingual glands: These are located right underneath your tongue on the bottom of your mouth.

Besides these major glands, you have hundreds of tiny minor salivary glands scattered across your lips, inner cheeks, and throat.

What Is Sialadenitis?

Sialadenitis is the medical term for inflammation and swelling inside one or more of your salivary glands. This happens when the gland becomes red, swollen, and very painful. This condition most often affects your parotid glands and submandibular glands.

Sialadenitis can present in different forms:

• Acute: Symptoms appear suddenly and progress quickly over a short period.
• Chronic: Swelling and discomfort persist over a longer duration.
• Recurrent: The condition clears up temporarily but keeps returning repeatedly.

While this is not the most common health issue, anyone can develop it at some point in their life.

Who Is Most Likely to Get Sialadenitis?

As mentioned before, people of any age can develop this condition. However, it is most commonly seen in adults over the age of 50, especially those who have salivary gland stones.

In addition, certain people have a higher risk of developing sialadenitis:

• Newborn babies during their first few weeks of life.
• People recovering from major surgery.
• people suffering from dehydration or poor nutrition.
• People with suppressed immune systems who struggle to fight off infections.

Is This a Dangerous Condition?

Most cases of sialadenitis can be cured successfully with proper treatment. However, if you leave the infection untreated, it can spread from your salivary gland into the deep tissues of your head and neck, causing severe infections. Because of this, seeing a doctor quickly is essential if you experience pain, swelling, or fever.

What Are the Symptoms of Sialadenitis?

Check if you are having any of these common signs:

• Swelling in one or more salivary glands, tenderness when touched, and skin redness around the area.
• Fever, especially if the inflammation has turned into an active bacterial infection.
• Reduced saliva flow, which can happen in both acute and chronic cases.
• Pain when you chew food, feeling as though something sharp is pricking inside your cheek.
• A very dry mouth, known medically as xerostomia.
• Visible swelling along your cheek and upper neck area.

Imagine your friend, let us call him David, has experienced cheek pain and mild swelling for two or three days. Eating feels difficult and uncomfortable, and he feels a low fever coming on. In situations like this, sialadenitis is a very likely cause.

If you notice one or more of these symptoms, you should consult a doctor promptly.

Why Does Sialadenitis Happen? What Are the Causes?

Several underlying factors can trigger sialadenitis:

• Bacterial or viral infections: This is the primary cause. For example, mumps is a viral infection that specifically targets and inflames your parotid glands.
• Dehydration: Not drinking enough water reduces saliva production, allowing ducts to become blocked and prone to infection.
• Recent illness: Other concurrent health conditions can weaken your body's defense mechanisms.
• Certain medicines: Drugs such as diuretics, antihistamines, and beta-blockers can reduce saliva flow and lead to this condition.
• Sjogren's syndrome: This is an autoimmune disease where your immune system mistakenly attacks your own moisture-producing glands.
• Poor oral hygiene: Failing to keep your mouth clean lets harmful germs enter your gland ducts.
• Salivary gland stones: Hard deposits can block the tiny tubes that carry saliva into your mouth.

Is This Disease Contagious?

Whether sialadenitis is contagious depends entirely on the underlying cause of the condition.

• If an infection caused it: Yes, bacterial or viral infections can spread to other people through coughing, sneezing, or direct contact with infected saliva.
• If a salivary stone caused it: No, if sialadenitis is triggered by a blocked duct or stone, it cannot be passed to someone else.

How Do Doctors Diagnose Sialadenitis?

When you visit a doctor, they will start by asking about your symptoms and performing a physical exam. They will gently feel your swollen areas and inspect the inside of your mouth.

In some cases, doctors use a thin, lighted instrument called an endoscope to look inside your salivary ducts.

Imaging tests such as an ultrasound or a CT scan may also be ordered to check for blockages, inflammation, or salivary stones.

Sometimes, your doctor may refer you to an ear, nose, and throat specialist, known as an ENT specialist or otolaryngologist, for advanced care.

How Are Swollen Salivary Glands Treated?

Doctors use several approaches to treat sialadenitis. The right choice depends on the severity of your specific condition.

Main treatment options include:

• Antibiotic medicines .
• Helpful home care remedies .
• Nonsurgical treatments .
• Surgical procedures .

Antibiotics.

If a bacterial infection caused your sialadenitis, your doctor will prescribe antibiotics such as dicloxacillin, cephalosporin, or clindamycin. Taking these medicines exactly as prescribed for the full course is essential for a complete recovery.

Home Remedies.

Your doctor may recommend simple steps you can do at home to ease pain and encourage saliva flow:

• Drink plenty of water every day. Aim for at least eight glasses daily.
• Sip fresh lemon juice or suck on sugar-free sour candies or lozenges to stimulate saliva production.
• Apply a warm compress gently to the outside of your swollen cheek.
• Massage the affected salivary gland gently in circular motions.
• Maintain excellent oral hygiene by brushing twice daily and flossing regularly.

Nonsurgical Treatments.

In more severe cases, staying in a clinic or hospital may be necessary to receive intravenous fluids (IV fluids) like saline or dextrose to keep your body hydrated. Doctors can also deliver intravenous antibiotics directly into your bloodstream to control serious infections.

Surgical Treatments.

If conservative treatments do not relieve your symptoms, your doctor may suggest surgery.

• If an abscess has formed inside the gland, a minor surgical procedure can drain the trapped pus safely.
• If hard stones are blocking your saliva ducts, surgery may be needed to remove them.
• Doctors sometimes use a tiny camera tool called a sialendoscopy to inspect inside the duct and clear blockages.

How Long Does It Take to Recover?

In most cases, with conservative treatment, salivary gland infections improve within about one week.

However, if you needed minor surgery, your full recovery might take up to two weeks.

Will Sialadenitis Go Away on Its Own?

Mild swelling or minor irritation might resolve independently or with simple home care. However, if your symptoms persist—such as ongoing swelling, severe pain, fever, or trouble swallowing—you must see a doctor right away. Waiting too long can lead to dangerous complications.

How Can We Lower the Risk of Sialadenitis?

While preventing this condition completely is not always possible, you can lower your personal risk by following these steps:

• Drink plenty of water throughout the day.
• Practice good oral hygiene by brushing and flossing daily.
• Eat a balanced, nutritious diet.
• Avoid smoking and using tobacco products.

What Can You Expect If You Have Sialadenitis?

Normally, with simple medical treatment, you will start feeling better within one week. If you underwent surgery, expect swelling and tenderness to subside over two weeks.

Some people experience recurrent bouts of sialadenitis. While you cannot always prevent future episodes, practicing good oral hygiene, staying well hydrated, and avoiding smoking will help lower your risk.

When Should You See a Doctor?

If you experience signs of sialadenitis that do not improve—such as facial swelling and fever lasting longer than three days—schedule an appointment with your doctor. Your doctor can find the exact cause of your swollen gland and provide the correct treatment.

When Should You Go to the Emergency Room (ER)?

If sialadenitis causes severe symptoms like breathing difficulties or trouble swallowing, call 911 (US/Canada), 999 (UK), or visit the nearest Emergency Department right away. Getting emergency medical help prevents dangerous life-threatening complications.
