question: My husband has noticed in the last two weeks he has white bumps on his upper gums, they are not raised and are not painful or itchy and they are not raised. He has quite chewing tobacco for 6 months now after 8 years and is also on ramipril for high blood pressure. I asked him about his toothpaste and it is crest health pro. Please help me with what this may be as he is having anxiety over them.
