Staining of teeth can be intrinsic or extrinsic. Intrinsic staining is below the surface of the tooth and is harder to remove. Extrinsic staining is stain on the surface of the tooth such as residue from food or drink and build-up that covers the tooth enamel.
Intrinsic stain may require teeth whitening either in-office or at-home whitening products. This type of stain is not removed with whitening toothpaste.
Extrinsic stain removal will respond well with regular dental cleanings and brushing teeth with whitening toothpaste.
If you choose to use whitening toothpaste, make sure your product has a fluoride or anti-cavity containing ingredient. Without this ingredient, you are more prone to cavities.
