Today I noticed a small hard bump on the roof of my mouth.  I have just gotten over a cold and have a cold sore on my lip and also I ate some fried tortilla chips that always tear up my gums could that be it?  I know it wasnt there this morning when I brushed my teeth
Hi, Thanks for posting the query, This could be due to infection from the tooth, any type of trauma, benign lesion. I would suggest you to get a checkup done, an OPG radiograph of the lesion is required. Is the lesion painful?? Could also be due to allergic reaction. Take care!
