If your tongue burn is severe, it's important to seek medical attention immediately. This includes burns that are classified as second or third-degree, or burns that cover a large area of your tongue. Also, if your tongue burn does not seem to be healing after one to two weeks, or if you experience signs of infection such as redness, swelling, or pus, it's important to consult a healthcare provider. Cleveland Clinic does not endorse non-Cleveland Clinic products or services, so make sure to consult with your own healthcare provider for the best treatment options for you.
