Staining on teeth can occur for several reasons, but they care classified as ether extrinsic or intrinsic. Both are important to understand. Extrinsic stains occur on the exterior or surface of the tooth while intrinsic occur in micro-cracks located deep within the dentin and enamel of the tooth. The dentin is the layer located under the enamel or white exterior. In some cases, over-the-counter whitening products can work to remove extrinsic stains from the exterior, but they are not effective at intrinsic stains. Teeth whitening agents work on both hard-to-clean extrinsic stains and intrinsic stains.
Stella White offers a solution in its teeth whitening products. These contain an active ingredient that is able to remove discoloration from the enamel. It does this through the use of oxygen molecules that react with the discolored molecules located on the teeth, breaking down the connection points. As the oxygen molecules work, they spread out, covering the entire tooth and whitening it. Stella White creates a clean, bright smile as a result. For some people, the results are immediate, but others will need to work at the process over time. Each person is different and results may vary.
