Drinking or eating food that is too hot can result in painful burn blisters on the tongue. These burn blisters can make it hard to eat, sleep, drink or talk, and can remain painful even when you aren't doing anything at all. You could take a medicinal painkiller to help the discomfort subside, but you may already have the key to comfort in the cupboards of your own home. Use home remedies for burn blisters on the tongue to help you deal with the pain until the tongue heals and the pain subsides.

When your tongue is dry, the blisters can be even more painful. Michael W. Dodds, Ph.D. assistant professor in the Department of Community Dentistry at the University of Texas Health Science Center in San Antonio notes that mouth burns can often deplete your mouth of moisture, leaving it dry and parched and even more painful. Keep a bottle of water on hand and drink it frequently to keep your mouth moist to deal with the pain.
Cold foods can help numb the pain temporarily so that you can eat and drink with less pain. Some ideal cold foods that you can eat for a mouth burn include yogurt, Popsicles, applesauce or frozen drinks. Cold foods make it easy for you to eat without having to do too much with your mouth. Choose foods that slide past your tongue and down your throat easily so you don't need to move your tongue around any more than is absolutely necessary. This gives your tongue plenty of time to heal.
Salt Water Gargle
The U.S. National Library of Medicine recommends gargling with cool salt water to help pain subside. It's a popular canker sore remedy that works on mouth blisters, too. Mix 1 cup of cool water with a teaspoon of salt and stir to dissolve. Pour the mixture in your mouth and gargle over a sink for at least 30 seconds. If possible, swish the salt water mixture around your mouth, making sure that it coats your tongue. Not only does salt help to relieve the pain, it can help clean the blisters and promote faster healing.
Avoid Certain Foods
One thing that may speed healing for your mouth blisters is to avoid spicy or hot foods. Spicy foods can inflame the blisters, causing you more pain and halting the healing process. The capsaicin in spicy foods is irritating to broken skin. Avoid foods that caused your mouth blisters in the first place, warns the American Academy of Family Physicians, like hot coffee, tea and steaming hot foods.
