Hi
Welcome to the MedHelp forum!
Small white bumps could be mouth ulcers due to iron and Vit B deficiency or poor oral hygiene, or could be due to Herpes infection or could be the result of abrasion from a mal-aligned tooth or an old tooth brush.
It is difficult to comment beyond this at this stage. Do consult your PCP and a dentist. Take iron and multivitamin pill and see if it helps. Change your tooth brush. Practice good oral hygiene. Test for Herpes. Avoid spicy and too hot food. Please let me know if there is any thing else and do keep me posted. Take care!
Sometimes, while brushing my teeth too quickly I hit my gums with my toothbrush. This hurts like heck and within a day or two I have a mouth ulcer there. Are they bumps, or are they kind of indents in your gum? If you caused any trauma to your mouth recently, I'd say they are probably a mouth ulcer.
However, if you're worried or they don't go away within a week, I'd consult with your physician.
they sounds like mouth ulcers to me
