Tongue blisters commonly form due to an injury like suddenly biting the tongue with your teeth, scalding your tongue accidentally and grinding your teeth.
Other causes include food allergies, viral infections, canker sores, mouth ulcers, burning tongue syndrome, enlarged papillae and certain medical conditions like diabetes, anemia and oral cancer.
Excessive smoking, vitamin B deficiency, eating too much fatty foods, side effects of some medication and use of chemical-based mouthwashes can also contribute to this problem.
Tongue blisters may be yellow or white, surrounded by a reddened area. The pain and inflammation associated with tongue blisters can make anyone feel irritated. Plus, the blisters can make it difficult to eat food properly.
In general, tongue blisters last for about a week and disappear on their own. However, you can try some natural remedies to help alleviate the pain and inflammation. Some remedies also promote faster healing.
