Whiteness challenging cases – Tetracycline-stained teeth

Author: João Cardoso Ferreira – Portugal

Anterior teeth chromatic deficiencies cause a huge impact in the smile esthetics and are, in most cases, the patients’ chief complaint. The whitening treatment is an efficient and conservative way to solve most cases.

FGM has a complete line of whitening systems: in-office, supervised at-home, for non-vital teeth and stain remover. The Whiteness line has been developed to achieve excellent results in both simple and challenging cases.

Teeth stained by tetracycline are challenging cases because they are more resistant to treatment with whitening gels, and thus directly affect the patient’s self-esteem. Check out the efficiency of Whiteness Perfect 10% in a clinical case of stained tooth, whose treatment lasted 6 months.

Case report: Among the several etiologies of dental darkening, the ingestion of tetracycline has been considered one of the most challenging for whitening treatments. Its prognostics can be favorable, depending on the location and coloration of the stains. Such stains are classified as intrinsic, that is, when the patient is exposed systemically during the development of the dental organs.1 The supervised at-home treatment technique using 10% carbamide peroxide for 24 consecutive weeks has been preferred as a safe whitening alternative or an alternative for improving tetracycline-darkened teeth2 and shows color stability for at least 90 months after whitening. ³
