5. Which teeth are not suitable for whitening? TOP

The natural tooth and the filling are composed of different substances.
It is therefore almost impossible to bleach the natural tooth and the filling to the same shade.
- Heavy tetracycline staining will not respond to bleaching.
- Teeth that have had root canal treatments often discolour internally. They may respond to internal bleaching. The tooth is opened and the bleach is applied. It is usually only moderately successful.

- Whitened teeth will only keep their colour if they are maintained by regular brushing, flossing and the use of whitening toothpastes.
