If you find an irritated patch on your tongue, it's tempting to ignore it and hope that it gets better on its own. But if you can't attribute this irritated patch to a specific cause like a burn, abrasion, or trauma, then your condition warrants a trip to the dentist to figure out if it's a sign of something dangerous. Any such oral lesions need to be investigated in case they're a red flag for a precancerous condition. Possible oral lesions include erythroplakia, leukoplakia, or erythroleukoplakia. It's natural to feel overwhelmed, but we're here to guide you through the process. Remember, by not ignoring the red flag, you will help reduce your chances of developing oral cancer.
