Why are my teeth stained? What could have caused it?
Extrinsic Teeth Stains: An extrinsic tooth stain is staining on the surface of the tooth. It occurs when stain particles, such as pigmented residue from food or drink, build-up in the film of protein that covers the tooth enamel. Extrinsic tooth stains are typically caused by to***co use or by regularly drinking coffee and tea, wine or cola drinks. This type of tooth stain responds well to regular dental cleaning and brushing the teeth with whitening toothpaste.
Intrinsic Teeth Stains: An intrinsic tooth stain is staining below the surface of the tooth. It occurs when stain-causing particles work through the exterior of the tooth and accumulate within the tooth enamel. Excessive fluoride use and also have been associated with intrinsic, especially in children. An intrinsic tooth stain is trickier to remove, but it can be done. An intrinsic tooth stain may require bleaching using professional or at-home chemical teeth-whitening products, such as Whitestrips.
Age-Related Teeth Stains: Age-related teeth stains combine the results of both intrinsic and extrinsic tooth discoloration. Because the core tissue of your teeth, the dentin, naturally yellows over time, teeth discolor with age. As we age, the enamel that covers the tooth becomes thinner, allowing the dentin to show through. These intrinsic causes of discoloration combined with extrinsic causes such as the effects of certain foods, beverages, and to***co, will cause most adults' teeth to discolor with age.
