Srikant gcye (CONVERTER SUPERVISOR)

Black teeth can occur due to extrinsic stains or intrinsic problems. Extrinsic stains usually happen when the enamel surface collects discoloration from food, drinks like tea, coffee, red wine, or habits such as smoking. Intrinsic causes are deeper, like cavities, dead pulp, or trauma that kills the inner tissue of the tooth. If only the surface is stained, professional cleaning or whitening can help. But if the discoloration is because of decay or pulp death, a dentist may need to do a root canal or crown.
