How does whitening work?
We know that whitening works, but how does it work?
Dental dyschromias can be classified in two ways: extrinsic or intrinsic. The intrinsic dyschromias are those spots that occur inside the tooth or those that affect the internal structure of dental tissues, these spots will be removed with Opalescence products but only in consultation treatments performed by the Dentist. The extrinsic dyschromias are The spots that appear on the surface of the teeth occur between the micro-cracks of the enamel and the depth of the dentin (the layer of the tooth under the enamel). Whitening toothpastes and mouth rinses can remove some of these extrinsic stains, but only professional whitening agents can remove the most difficult and deep stains.
The active bleaching agent (hydrogen peroxide or carbamide peroxide) contained in Opalescence gels penetrates the enamel to reach the molecules responsible for the spots. The free radicals of oxygen released by the bleaching agent decompose these molecules (breaking the bonds that hold them together), making them invisible.
Why choosing a whitening should be done under the supervision of the dental professional?
The whitening treatment done under the supervision of a dental professional is a guarantee of safety and makes it possible to obtain the best possible results. The whitening should be carried out only after a correct anamnesis of the patient that allows identifying the most appropriate treatment to their needs. The whitening treatment should always be preceded by a professional cleaning since the dental plaque inhibits or reduces the effect of the bleaching agents. Finally, the dental professional oversees the entire process, controlling progress and treating side effects or possible adverse reactions such as tooth sensitivity.

Does whitening cause sensitivity in the teeth?
Sensitivity in the teeth is a relatively common side effect of bleaching. If sensitivity occurs, it will be transient and disappear once the whitening is completed.
