Aim:

To present three clinical cases of discoloration in calcified upper anterior teeth, that were resolved following different clinical protocols for teeth whitening to return the aesthetics of the anterior teeth.

Clinical cases:

Each clinical case of discoloration was treated following a different treatment protocol based on a correct clinical and radiographic diagnosis. All cases had a favourable outcome and have no regular review.

Conclusion:

In clinical cases as those presented in this article where the canal and pulp chamber are totally calcified or obliterated, it was possible to perform internal and or external whitening to restore optical harmony in a conserv-ative way. This type of treatment would allow responding to the high prevalence of aesthetic demand due to trauma and colour changes.
