Teeth stains have many causes, and mostly are 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, drink or tobacco. This type of tooth stain responds well to regular dental cleaning and brushing the teeth with whitening toothpaste.
Today case is about intrinsic stain. 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.
An intrinsic tooth stain is trickier to remove, but it can be done. If the accumulative stain layer is shallow and superficial on enamel, less than 0.2mm, we can combine teeth whitening and micro-abrasion technique to remove the intrinsic stain.
