What causes white bump inside mouth?
Patient: Im 17 with no history of medical problems. Yesterday I found a small white bump on the left inside of my mouth. It doesnt hurt unless I scrape my teeth along it. And I'm really worried on what it could be. I was eating sunflower seeds the day before I found the bump and was wondering if one had maybe caught onto my lip. But why would that cause a bump? Doctor: Hello thanks for consulting at hcm..You may have inadvertently bit into your buccal mucosa on the inner side of the oral cavity.. resulting in microtrauma to the tissues ..hence the bump,.,.please blow air with mouth closed..so that the sharp teeth surfaces do not touch the buccal mucosa..please trim the sharp surfaces of the teeth by consulting a oral physician..if problem persists..nothing to worry as of  now,,hope it helps,,take care,,,
