Did you accidently bite your tongue? Or scalded it while gulping down a cup of hot coffee? It’s no surprise that you ended up with a painful blister on your tongue.

Tongue blisters, also known as tongue zits, are fairly common and not a very serious problem. They tend to heal on their own within a week. But that can seem like forever if it’s turned eating, drinking and even speaking into a painful experience.


Symptoms and Causes of Tongue Blisters

Tongue blisters usually appear as yellow or white bumps on the tongue surrounded by reddish skin. They are fairly common and can occur due to:

  • Biting your tongue or grinding your teeth.
  • Eating very hot food that scalds the tongue.
  • Enlarged papillae, canker sores, mouth ulcers, infections in the mouth, diabetes, anemia or oral cancer.
  • A vitamin B deficiency.
  • Excessive smoking.
  • Use of chemical-based mouthwashes.

Preventing Tongue Blisters

  • Avoid eating very hot, spicy or acidic foods.
  • Do not drink alcohol or smoke. Both increase the bacteria in your mouth, giving way to infections that can cause blisters.
  • Eat foods rich in vitamin B like eggs, cheese, sardines and more. This will prevent tongue blisters due to a vitamin B deficiency.
  • Treat or manage any underlying health condition that can lead to tongue blisters.

Home Treatment for Tongue Blisters

Though the blisters tend to heal up on their own, you can use a few home remedies to soothe the inflammation and pain. If the remedies fail to provide relief after a week, it warrants a trip to the doctor.

Read on to learn five home remedies you can use to get rid of tongue blisters.

Method 1: Ice

Applying ice on tongue blisters is the most common and effective remedy for tongue blisters. Ice helps numb the inflamed area temporarily and lessens the pain. It also helps reduce the swelling.


Single-Step Treatment: Put ice on the blister

use ice

  • Hold an ice cube against the blister until the ice melts. You can also suck on the ice cube if that is more convenient.
  • Additionally, you can sip on ice water whenever the blister starts hurting.

Applying ice will give you immediate pain relief. To help the blister heal completely, repeat the application 4 or 5 times a day for 2 to 3 days.

Method 2: Salt Water (Saline Solution)

Your mouth hosts a colony of bacteria that can infect a blister and make things worse. A salt water, or saline solution, not only helps reduce the inflammation and pain but also helps disinfect the area.

Step 1. Prepare the saline solution

prepare saline solution

  • Add 1 teaspoon of salt to 1 cup of warm water.
  • Stir well until the salt dissolves completely.

Step 2. Gargle with the saline solution

gargle with saline solution

  • Gargle with the saline solution for 20 to 30 seconds, then spit it out.
  • Repeat until you have used up all of the solution.
  • Finish up by rinsing your mouth with warm water.

Repeat 2 or 3 times daily for 2 to 3 days to treat blisters on your tongue.


Method 3: Aloe Vera Gel

Freshly extracted aloe vera gel can help soothe and treat a tongue blister. Aloe vera gel is anti-inflammatory and antibacterial in nature. It imparts a cooling effect on the inflamed blister and also aids the healing process. For similar reasons, aloe vera gel can also be used to treat sunburns.

Single-Step Treatment: Apply aloe vera gel on the blister

use aloe vera

  • Gently apply fresh aloe vera gel on the blister.
  • Leave it on for 5 minutes, then rinse your mouth with lukewarm water.

Apply aloe vera gel 3 times daily for 3 to 4 days to treat the tongue blister.

Method 4: Vitamin B

increase vitamin B intake


Sometimes, a deficiency of vitamin B can lead to blisters on the tongue. Thus, increasing your intake of vitamin B-rich foods can help get rid of tongue blisters and deter their recurrence.

  • Eat foods high in vitamin B, such as eggs, cheese, sardines, beef liver, whole grains, bananas, milk and avocados.
  • You can also take 1 tablet of vitamin B-complex every day for 1 week to meet your daily need for vitamin B and help the blister heal. Consult your doctor for continued use of any supplements.

Method 5: Honey and Milk

A concoction of cold milk and honey can help soothe a tongue blister and heal it faster. Cold milk reduces the concentration of natural acids in your mouth, thus reducing irritation around the blister. Honey lends antibacterial properties and helps retain the moisture in the blister to aid the healing process.

Note: Do not use this remedy for children under age 1, as honey can lead to infant botulism.

  • Do not eat crunchy foods while suffering from a tongue blister, as the sharp edges of such foods can scratch the inflamed area and cause more pain and irritation.
  • Stop smoking and drinking alcohol. They not only cause tongue blisters but also delay the healing process for existing blisters.
  • Hydrogen peroxide can help heal a tongue blister. Dilute 3% hydrogen peroxide with an equal quantity of water. Apply it on the blister for 2 minutes, then rinse your mouth with water. Do this several times a day to disinfect the tongue blister and speed up the healing.
  • A baking soda paste made with some water can also help. Apply it as a poultice over the blister for 5 minutes before rinsing it off with water. Do this 3-4 times a day until you get relief.
