I have these brown spots on my teeth and I am getting very concerned. I have never had a cavity before nor do I smoke and I don't eat a lot of
sugar either. I have been brushing my teeth at-least twice a day for the past 1 year. The spots don't hurt and are on the surface of my premolars & molars. At the moment there is one in between my teeth grooves on the lower right region and one brown spot is on the upper right region. This is becoming very stressful as I am worried for possible tooth decay or cavities.
