Updated: May 27

A Woman Showing Her Swollen Tongue.

A swollen tongue can be uncomfortable and concerning. It can make it hard to talk, eat, and even breathe. Whether it happens suddenly or lasts a long time, knowing the causes, symptoms, and treatments is important for quick relief. In this guide, we'll talk about the different reasons why your tongue might be swollen and what you can do to get better.

What Causes a Swollen Tongue?

A swollen tongue can be confusing and uncomfortable. Many people want to know what caused their tongues to swell. Knowing what can cause your tongue to swell is important for proper care and quick treatment.


Allergies are a common reason for a swollen tongue. When you eat or touch something you're allergic to, like certain foods, medicine, or things in your environment, your body reacts and your tongue can get swollen. If you know what you're allergic to, you can try to stay away from those things so your tongue doesn't swell up again.


Infections, like viruses and bacteria, can also cause a swollen tongue. If you have something like oral thrush or stomatitis, your tongue can become swollen and uncomfortable. It's important to brush your teeth and take care of your mouth to prevent tongue swelling. If you think you have an infection, you should see a doctor right away to get it treated.

Trauma or Injury

Accidentally hurting your tongue can also cause it to swell. This could be from biting your tongue, burning your tongue on hot food, or other physical damage. While these accidents usually aren't too serious, they can still cause pain. You should take care of your teeth and mouth and be careful to avoid accidentally hurting your tongue.

Underlying Medical Conditions

Some medical conditions can also cause a swollen tongue. Hypothyroidism (which is when your thyroid gland doesn't produce enough hormones), inflammatory disorders (which are diseases that cause swelling in your body), or autoimmune diseases (which are diseases where your body attacks itself) can cause your tongue to become swollen. If you think you have one of these conditions, you should talk to your doctor about how to manage it.


Some medicines can cause your tongue to swell. It's important to know what side effects your medicine can have and to tell your doctor if you're having any strange symptoms. They can help you figure out if you need to change your medicine or try a different one.


Sometimes, your genes can make you more likely to have a swollen tongue. If you have a family history of allergies or other conditions that cause your body to swell, you might be more likely to have a swollen tongue too. If you know that you have a family history of these conditions, you can take steps to prevent your tongue from swelling.

Hormonal Changes

For women, their hormones can also cause their tongue to swell. This can happen during their menstrual cycle or when they're pregnant. If you're a woman and you're having these problems, you should talk to your doctor about what you can do to make it better.

Dental Issues

If you don't take good care of your teeth, you might get an infection in your gums or a tooth abscess (which is when you have an infection in your tooth). These things can cause your tongue to swell. It's important to brush your teeth regularly and floss to prevent these things from happening.


If you don't drink enough water, you can get dehydrated. When you're dehydrated, your tongue gets dry and this can cause it to swell. Drinking enough water is a good way to prevent this from happening.


Stress can make other health problems worse, even if it doesn't directly cause your tongue to swell. To help prevent this, you can try to relax and not worry too much. You can do things like deep breathing or meditation to help you relax.

Symptoms of a Swollen Tongue

A swollen tongue is not just uncomfortable; it can also be worrying. Knowing the signs of a swollen tongue is important so you can get help early and manage it well. Let's look at some common signs that might mean your tongue is swollen.

  • Visible Swelling: The clearest sign is when your tongue looks bigger than normal. It might swell up in different areas.

  • Discomfort or Pain: When your tongue is swollen, it can hurt and feel uncomfortable. The area where your tongue is swollen might be tender and hurt when you touch it or move it around.

  • Changes in Color: If your tongue is swollen, it might change color. It could turn red or look like it's a different color. This might mean that your tongue is inflamed or that there's another problem.

  • Difficulty in Speaking or Swallowing: A swollen tongue can make it hard to talk and eat. If the swelling is really bad, you might have trouble speaking clearly or swallowing. This can be a problem if you're trying to talk or eat.

  • Altered Taste: When your tongue is swollen, it can affect how you taste things. This is because the part of your tongue that lets you taste is swollen. So, you might not be able to taste things as well as usual.

  • Numbness or Tingling: Sometimes, you might feel like the swollen part of your tongue is numb or tingling. This can make the discomfort even worse.

  • Breathing Difficulties: If your tongue is really swollen, it might get in the way of your breathing. This is because the back of your tongue can get in the way of your airway. If this happens, it's very important to get help right away.

  • Excessive Salivation: When your tongue swells, it can make your mouth make more saliva than usual. This might make it hard to control, and you could end up drooling.

  • Foul Breath: If your tongue is swollen because of an infection, it might make your breath smell bad. This is because the swelling gives bacteria a warm, wet place to grow, and the bacteria can make your breath smell bad.

  • Fever: If your tongue swells because of an infection, you might get a fever. It's important to keep an eye on your temperature in these cases.

How is a Swollen Tongue Diagnosed?

If you have a swollen tongue, a doctor can help you find out what's causing it. Here's how a doctor might figure out what's going on:

1. Professional Consultation

If you have a swollen tongue, you should talk to your doctor. If the swelling is bad or doesn't go away, it's important to see a doctor. You might see a primary care doctor, an allergy doctor, or an ear, nose, and throat doctor.

2. Physical Examination

The first thing a doctor might do is look at your tongue. They'll check to see how swollen it is, if there are any marks or other things that look wrong, and if there's any sign of infection or injury.

3. Medical History

It's important to tell the doctor about any health problems you've had in the past, like allergies or infections. You should also tell them about any accidents or injuries you've had to your tongue or anything else that might have caused the swelling. This will help the doctor figure out what's wrong.

4. Diagnostic Tests

Based on what the doctor sees and what you tell them about your health, they might ask you to do some tests. These might include:

  • Blood Tests: Blood tests can show if you have an infection, inflammation, or other health problems. This can help the doctor figure out what's causing your tongue to swell.

  • Allergy Testing: If you think you might be allergic to something, the doctor might do an allergy test. This might include a skin test or a blood test that looks for things that might make you allergic.

  • Imaging Studies: Sometimes, the doctor might want to look inside your body using special machines. These might include X-rays or MRI scans, which can help the doctor see what's going on with your tongue and the area around it.

5. Oral Swabs and Cultures

If the doctor thinks you have an infection, they might take a swab or a sample of the part of your tongue that's swollen. This can help the doctor figure out what kind of infection you have and what medicine will help.

6. Biopsy

If doctors aren't sure why your tongue is swollen or if they see something strange, they might suggest a biopsy. This means taking a tiny piece of tissue from your tongue to look at it more closely.

7. Specialized Consultation

Depending on what the doctor finds at first, they might send you to see other doctors who specialize in certain things. These could include an allergy doctor, an immunologist (a doctor who studies the immune system), or an oral and maxillofacial surgeon (a doctor who works on the mouth, jaw, and face).

How to Treat a Swollen Tongue

If you have a swollen tongue, there are different ways to treat it depending on what's causing it. These are some of the ways you can treat a swollen tongue:

1. Home Remedies

  • Cold Compresses: If your tongue is swollen, putting a cold pack on it can help bring down the swelling and make you feel better. You should put the cold pack on your tongue gently and for a little bit of time.

  • Saltwater Rinses: Rinsing your mouth with salt water can help to make your swollen tongue feel better. Mix a little bit of salt in some warm water and then swirl it around in your mouth for half a minute, then spit it out.

  • Hydration: It's important to drink enough water if your tongue is swollen. If you don't drink enough water, your tongue can swell even more. Make sure you drink water throughout the day to stay hydrated.

2. Over-the-Counter Medications

  • Anti-Inflammatory Medications: You can take medicine like ibuprofen to bring down the swelling in your tongue and make the pain go away. Make sure to follow the directions on the medicine so you don't take too much.

  • Antihistamines: If you think allergies are making your tongue swell, you can try over-the-counter allergy pills. These can help stop allergic reactions that are making your tongue swell.

3. Medical Interventions

  • Prescription Medications: If your tongue stays really swollen or doesn't get better, doctors might give you stronger medicine to treat the cause or to manage how you feel.

  • Epinephrine (for Allergic Reactions): If your tongue is swollen because of a really serious allergic reaction, you might need to use an EpiPen. This is a device that gives you medicine to stop the allergic reaction. If this happens, you need to go to the hospital right away.

4. Healthy Lifestyle Choices

  • Balanced Diet: Eating a variety of foods that give you all the vitamins and minerals you need helps keep you healthy. This lowers the chances of not getting enough of certain nutrients, which can make your tongue swell.

  • Hydration: Drinking enough water is still one of the best ways to prevent tongue swelling. It's important to drink water every day so that your body stays healthy.

When to See a Doctor

If you have a swollen tongue, you might be able to treat it at home, but there are times when you should see a doctor right away. Knowing when to act fast can stop problems from getting worse and make sure you get the best care. Here's when to get help from a doctor.

  • Severe Swelling: If your tongue gets very swollen quickly, or if it spreads to your throat, you need to see a doctor right away. This could be really dangerous, especially if it makes it hard to breathe.

  • Difficulty Breathing: Having trouble breathing is a big warning sign. If your tongue swelling makes it hard to breathe, you need to get help right away. This might mean calling for an ambulance or going straight to the emergency room.

  • Persistent Symptoms: If your tongue is still swollen after you've tried to make it better at home or with over-the-counter medicine, you should go to the doctor. This is because your tongue might have a problem that needs a doctor's attention.

  • Speech Impairment: If your swollen tongue makes it really hard to talk or say words clearly, you should see a doctor. Trouble speaking could mean there's a bigger problem that needs a doctor to check it out.

  • Systemic Symptoms: If your tongue is swollen and you also have other symptoms like a fever, feeling tired all the time, or losing weight for no reason, you should go to the doctor. These symptoms might mean there's an infection or another problem that needs to be checked out and treated.

  • Allergic Reactions: If you think your tongue is swollen because of an allergic reaction, and you have other symptoms like hives, trouble breathing, or other parts of your body are swollen too, you need to get medical help right away. This is a really serious problem and you need a doctor to help you.

  • Recurrent Episodes: If your tongue keeps swelling up, even if it's not very bad, you should go to the doctor. The doctor can help you find out what's causing the swelling and help you stop it from happening again. This can help make you feel better and improve your life.

  • Painful Swelling: If your tongue is really swollen and hurts a lot, and regular pain medicines don't help, you should see a doctor. If the pain keeps going, there might be something else going on that needs a doctor's help.
