What are tongue bumps?

What Does It Mean When You Have Bumps on the Back of Your Tongue? (1)

We all have several hundre d bumps on our tongues called papillae, also known as the taste buds. Inflamed bumps on the back of your tongue — the circumvallate papillae — usually aren’t a cause for concern and will heal on their own.

We all have several hundred bumps on our tongues called papillae, also known as the taste buds. There are four types of these papillae:

  • Filiform papillae, covering about two-thirds of your tongue and responsible for its sense of touch
  • Fungiform papillae, which distinguish flavors and temperature
  • Foliate papillae, lining the sides of your tongue
  • Circumvallate papillae, which are large bumps toward your throat positioned in a V-shape

Normally, these bumps are largely unnoticeable — they have a consistent color and texture, supporting your ability to eat.

But sometimes tongue bumps can appear swollen. While enlarged papillae may just be a short-term nuisance, they can also make it difficult or painful to eat, talk, swallow, or even taste food.

Inflamed bumps on the back of your tongue — the circumvallate papillae — usually aren’t a cause for concern and will heal on their own. However, severe, spreading, or longer-lasting bumps might be a sign of another underlying condition that requires a doctor’s treatment.

Because your oral health is tied closely to your overall well-being, it’s important to know why you have bumps on your tongue and when to seek medical care.

Signs and symptoms of tongue bumps

Inflamed bumps on the back of your tongue are usually visible, appearing larger and swollen. Sometimes they may change color as well, to white, bright pink, or black patches.

Enlarged taste buds may also cause:

Change in taste

The papillae on the back of your tongue aren’t responsible for taste. But if the inflammation has spread, you may experience a partial or total loss of your taste sensation or have difficulty discerning between flavors like salty, bitter, sweet, or sour.

Difficulty moving your tongue

As the bumps on the back of your tongue swell, it can be hard to move your tongue normally.

Depending on the severity, this could impact normal speaking and swallowing. Swelling can also make your tongue feel sore and appear larger — in some cases, the top and bottom teeth don’t fit neatly together around the tongue.

Pain or a burning sensation

While enlarged bumps can make your tongue feel sore, you may also experience a localized burning sensation in the problem area. This could be an ongoing discomfort or only felt when the tongue is in use, like as you eat.

A furry or hairy texture

Debris, bacteria, and dead skin cells can get lodged and stuck between inflamed tongue bumps. This accumulation causes a white, fuzzy-looking coat on the surface of your tongue.

Causes of tongue bumps

Tongue bumps are common and generally considered harmless — but they can also be a symptom of a more serious condition.

You may experience bumps on the back of your tongue due to:

Physical trauma

Accidentally biting your tongue can irritate your taste buds, making them swell. Eating or drinking extremely hot food can also burn and blister papillae.

Allergies

Sometimes an allergic reaction causes tongue bumps, especially with some fresh fruits and vegetables that contain certain pollen species, like melons, apples, and bananas.

Infection

Oral infections can spread to your taste buds, leading to enlarged bumps. The most common infection is called oral thrush, caused by the yeast Candida albicans. Along with swollen tongue bumps, signs of oral thrush include white lesions, burning, and soreness.

Tongue bumps are a symptom of other infections as well, including herpes simplex and syphilis. Certain antibiotics for infections can also cause your taste buds to swell.

Poor oral hygiene

If you don’t stick to a good brushing and flossing routine, bacteria can build up and cause inflammation throughout your mouth, including in your taste buds. Smoking can also have this same effect.

Dehydration

Not drinking enough water can cause dry mouth, a condition that increases your risk of taste bud infections, gum disease, and dental cavities over time.

Stress

Canker sores can form at the back of your tongue as well. While their cause is not well understood, research shows that psychological stress may play a role in triggering canker sores. Physical irritation, acidic fruits and vegetables, and hot spicy foods can also contribute to canker sores.

Disease

While uncommon, bumps on the back of the tongue can be a sign of oral or tongue cancer. These wart-like bumps — or squamous cell papillomas — can look white or red and may be benign. Only a doctor can diagnose an unusual bump as cancerous.

Leukoplakia is another condition that can cause tongue bumps. This occurs when the cells in your mouth grow excessively, irritating your taste buds. Some people with diabetes, anemia, and autoimmune diseases may also experience inflamed tongue bumps.

When to see the doctor for tongue bumps

Most enlarged tongue bumps will heal on their own, but you should visit your doctor if:

  • Your symptoms last longer than a week
  • Bumps are growing, spreading, or bleeding
  • Enlarged bumps keep returning after healing
  • Painful bumps interfere with your ability to eat or drink

Diagnosing tongue bumps

To diagnose what is causing your tongue problem, a doctor will first ask about your medical history and any known allergies. They’ll perform a tongue exam to look for changes in taste bud color, texture, and size, checking for irregularities to guide a course of treatment.

Your doctor might also order blood tests to rule out other issues like infection or disease. If they suspect cancer, the doctor will refer you to a specialist to perform a biopsy or remove the lump entirely.

Treatments for tongue bumps

Some causes of tongue bumps require treatment from a doctor, like antifungal medications for oral thrush.

You can relieve discomfort caused by most tongue bumps at home, however. Some home remedies include:

  • Drinking lots of water, through a straw if it’s more comfortable
  • Rinsing your mouth with warm salt water
  • Avoiding acidic and spicy foods and alcohol-based mouthwashes that irritate inflammation
  • Using topical numbing gels or creams
  • Taking over-the-counter anti-inflammatory and pain relief medication like ibuprofen
  • Not smoking or drinking alcohol

You should monitor the size, color, and spread of tongue bumps as you treat them at home — if there is no change or your condition worsens, make sure to make an appointment with your doctor.

The best home care you can do is prevention. Maintaining good oral hygiene can help prevent inflamed bumps at the back of your tongue and keep them from coming back.

Is it bad to scrape your tongue?

Tongue scraping is a way of removing bacteria, food particles, and other debris that causebad breathfrom the surface of your tongue. Tongue scraping is a painless and low-risk procedure. However, there may be some associated risks, such as:

  • Painor bleeding
  • Activation of gag reflex
  • Harm to taste buds, altering taste sensations

However, if done correctly and using the right technique tongue scraping can improveoral healthand minimize foul breath (halitosis).

What are different types of tongue scrapers?

Different types of tongue scrapers come in various shapes and sizes:

  • Brush tongue scrapers:Typically have a long handle like atoothbrushand a tip with ridges or short bristles to scrape the tongue, and must be replaced every 3-4 months of regular use.
  • Plastictongue scrapers:Made of thin plastic wire bent into a U-shape.
  • Metal tongue scrapers:Made of thin, U-shaped, metal wire and typically last longer than plastic ones. Copper and stainless-steel tongue scrapers can be used indefinitely if cleaned regularly. Copper also has antibacterial properties that help get rid of microbes.

To use a tongue scraper, start at the base of the tongue and pull the scraper forward so that it slides andscrapesall the buildup away.

5 benefits of tongue scraping

  1. Improves sense of taste:Scraping gets rid of all the dead cells and other buildup from the surface of the tongue and creates space for taste buds to function optimally. It may help you appreciate certain flavors or textures better.
  2. Freshens breath.Microbes such as bacteria gather in the mouth at night because your mouth doesn’t produce as much saliva when you’re sleeping. Cleaning the tongue using scrapers removes bad-breath causing bacteria.
  3. Reveals the tongue's natural color:Regular scraping removes discoloration caused by debris accumulated on the tongue and helps the tongue return to its natural, pink and clean state.
  4. Boosts immunity:Your tongue functions as the first line of defense for the body. By scraping toxins regularly, you prevent the buildup of bacteria that can weaken your immune system over time.
  5. Promotes betterdigestion:Digestion starts in your mouth, and your saliva contains a variety of enzymes that helps break down food for easier digestion in the gut. If your taste buds get blocked due to the accumulation ofmucusor other buildup, these receptors’ normal messaging function gets disrupted.
