One of the most common complaints about teeth whitening is dentinal hypersensitivity after whitening
The reason for this is simple: the teeth whitening gels de-hydrate the enamel, so when the teeth re-hydrate naturally in the first 24 hours some people can have sensitivity
WHITERx Pre whitening swabs are quite innovative in the way the dental liquid contained inside, penetrates inside the enamel rods to pre-hydrate the teeth to prevent or minimize post dentinal sensitivity.
The anionic foaming agents, aqueous cleaning technology also acts as a stain remover prior to whitening to optimize whitening results.
For these two reasons, it is a must to pre-whiten to deliver ultimate results, sparkling white teeth, and pain-free whitening
