Hello These are the stains that have to be cleaned by the dentist, so please visit the dentist and use soft, bristle toothbrush with fluoridated toothpaste twice daily in the right direction

These are extrinsic stains. They can be removed through scaling.

Observing the stains on your teeth, it is possible that they result from the use of herbal-based toothpaste, as some formulations may contribute to gradual staining. I recommend switching to a non-herbal toothpaste. Additionally, certain dietary habits, such as consuming coffee, tea, red wine, or dark-colored fruits, can lead to tooth discoloration.  If you engage in any of these habits, consider moderating them to maintain a brighter smile.
