[|Human|] Hi, my 13 mo old has had a small black spot on his gum just below one of his front middle teeth.  It has been there for about a week and I have tried brushing and flossing but it seems to be on the gum rather than underneath.  I have read this is from teething but he has had these 2 teeth for 5 mos.  Can you tell me if this is normal?
[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint a black spot over the gums over the gum of middle tooth seems to be most probably due to the traumatic injury to the gum caused by any hard food or tooth brush bristle that might have caused a bruise over the gums. Many a time it is due to impinge of food particles into the gum crevice and needs to be removed. So watch for few days, if it fades off it is fine and if it does not, get it removed by a dentist. As of now brush his teeth using a soft tooth brush. Hope this information helps. Thanks and regards. Chat Doctor.
