HELP!!! My 7 month old has had his bottom 2 teeth for about a month and a half now. My husband today noticed little black vertical lines on the backs of each tooth. We’ve been brushing his teeth morning and night, and he’s only had the teeth for a short while. I can’t imagine that he’s already got dental issues!!!? He did just try blueberries the past couple days, but I can’t believe that he would have two black lines on the backs and that brushing wouldn’t take away the stains. Has anyone had a similar thing happen before? Or, seen this happen before? Please tell me it’s not tooth decay, because that is all that comes up in google when I search. Nothing comes up about “lines”. I’ve made a call to the doctor and am waiting for a response about an appointment, but I’m just looking to see if someone else has dealt with this before. I’m pretty postpartum still, so this is terrifying me. Please be gentle in the comments. Thanks. 💛
