The short answer
Before-and-after Opalescence results are judged by comparing the starting shade with the final shade under similar lighting, after the teeth and gums have been assessed. Whitening changes natural tooth colour, but fillings, crowns, veneers, and bonding do not bleach in the same way.
What should be recorded before Opalescence whitening?
Have a dental examination and record the starting shade before treatment. Follow the prescribed application time, keep gel off the gingiva, avoid staining foods while following the clinician’s instructions, and report significant sensitivity or gum irritation.
What changes should prompt a review before whitening?
Seek review before whitening if one tooth is dark, the teeth hurt, gums bleed, or decay, cracks, exposed roots, or defective restorations are present. Contact the dental team if pain or tissue irritation persists after stopping.
When should you seek advice before whitening?
Ask how the shade will be recorded, what type of stain is present, whether restorations will need colour matching, and which Opalescence formulation and wear schedule are intended.
