[|Human|] I changed my tooth brush from one electric to another. 2-3 weeks later, I am finding black deposits in the upper surface of some teeth. No bleeding from the gums,there is 1 kind of a small blister on upper gum it doesn t bleed either. I cant scrape or brush away the black marks? Possibilities?
[|AI|]  Helloi have gone through your query. You have not mentioned your age. Black discoloration of teeth can be due to various reasons. Do you have any habit of chewing tobacco or smoking. Black staining can be due to high iron content in the water. Chat Doctor. Sometimes black discoloration can be a tooth decay also.is there any pus discharge from the blister or any pain related to the nearby tooth. If I was your treating doctor i would recommend you to have a full mouth scaling (cleaning) and polishing done. Aftercare would include use of mouthwash and maintain good oral hygiene .if this doesn't work then it could be a case of intrinsic staining or cavities would suggest you to visit a dentist and get it chekedHope this ans helpsRegards
