What to do about tongue blisters?

Red-spots-on-side-of-the-tongueYou must think that your tongue is a very small part of your body, but it plays an important role in your everyday life. Not only does it help in speaking and tasting, but indicates your overall health. When indisposed your tongue might be very uncomfortable, and sores or tongue blisters can cause inconvenience more than you may imagine.

Canker Sores

Canker sores are oral blisters that are the most common problem and occur to people at some point or the other in their life. They are typically small, with their diameter less than one third of an inch, and form on the inner sides of the cheeks, under the tongues or on the gums – if not on the tongue.

The sores may appear white or yellow in the middle and red on the borders. They start as painful red bumps or spots and may grow into open ulcers.

Canker sores are very discomforting. The pain usually goes away within seven to ten days on its own, but it takes almost three weeks or more for the ulcer to heal.


Canker sores are caused due to:

  • Celiac disease
  • Emotional stress
  • Hormonal shifts
  • Lower immune system

You must address mouth sores as soon as possible because if they become infected they may cause additional problems such as lymph nodes. You must visit your doctor if you develop any of the following at the same time:

  • Diarrhea
  • Fever
  • Joint Pain
  • Fever

For quicker healing you must maintain good oral hygiene. This can be achieved by brushing and flossing, and rinsing the mouth with antibacterial mouthwash, whose bubbling feature cleans the mouth while reducing irritation.



Candidiasis, also called thrush, is the overgrowth of the Candida fungus that develops naturally in your mouth. It is caused whenever the bacteria that protects your oral tissues are compromised, either through the consumption of antibiotics, ill-fitting dental appliances or medication induced dry mouth.

Common symptoms of candidiasis include:

  • A reduction in the sense of taste
  • White, cheesy looking patches of fungus
  • Red, inflamed patches of tissues or tongue blisters that are at times hidden by fungi
  • The corner of the mouth area cracked or red in appearance

Candidiasis usually heals in seven to ten days with consistent treatment. If however it does not or recurs quite often, then you must visit your doctor who will recommend tests for conditions like cancer, diabetes or HIV.

Candidiasis is often treated by physicians by antifungal treatments, either as lozenges or mouth rinses for mild cases and regimen tablets for severe conditions. Patients have been reported to develop immunity against these treatments over time, so doctors are very particular in prescribing treatments for every case of the fungus.

All you need to do is maintain good oral hygiene by brushing and flossing regularly, use antibiotics only when it is necessary and keep your mouth well hydrated. Many medicines prescribed contain traces of sodium fluoride to help reduce dry-mouth.



Injuries to the tongue may also cause sores that resemble tongue blisters. The following things may cause blister, burns or cuts onto the tongue:

  • Biting your tongue
  • Eating crunchy foods such as potato chips
  • Sipping extremely hot beverages
  • Sucking hard candies

These may lead to painful ulcers that may time to go away. But as long as an infection doesn’t develop onto them, they aren’t a cause of any concern.

If your tongue is prone to injury then you must avoid foods that may cause damage. These include foods with sharp edges and too hot drinks.

All you need to do is maintain good oral hygiene by brushing and flossing regularly, use warm salt water or mouth rinse for healing and protect natural bacteria balance in your mouth.
