Canker sores are small, painful reddish bumps that often appear under the tongue and usually heal on their own. They can be caused by a virus or may indicate a more serious condition like oral cancer. If you notice any unusual bumps on or beneath your tongue, it's important to consult your doctor. #CankerSores #OralHealth #HealthAwareness #ConsultYourDoctor #MouthSores #HealthTips #OralCancer
