[|Human|] I have a light brown line on either side of one tooth. They each start at the gum and then go down the line of the tooth. I floss and brush and nothing comes up. The rest of the gum isnt painful, puffy, or doesnt bleed. I just got my teeth cleaned by the dentist last week. just wondering what it might be?
[|AI|]  Hi. Thanks for the query. Well, light brown line on both sides of the tooth can be stains over the tooth or can be due to tooth decaying at the sides or proximal surfaces. It can be confirmed only with a clinical evaluation. In case of it is left over stain then scaling of the tooth can help in its removal. In case if it is due to decay then filling the tooth with tooth colored resin based cement can help. Hope this information helps. Regards.
