Its normal. i work in a dental office. SOunds like the doc did Bitewings/Pano and a dental exam. They check your teeth and gums(Oral cancer screening). If there was ANYTHING at all concerning, he would have told you. Sounds like everything is all good besides some minor gingivitis, which 9 out of 10 people have. Just need a good cleaning and keep up with your daily brushing and flossing you should be good to go!
