Recently I have noticed that the area on my upper gums around the teeth is a cloudy white, slightly rough, looks like its composed of small tiny bumps. I have never had many dental problems, and brushed but not flossed regularly, until now. They are painless, no red or bleeding, no tenderness, everything still has feeling and my teeth do not feel loose or receding. And its not patchy at all, it looks like white small bumps which surround where the teeth insert into the gums.
