of grey-black color--and aging.
The intra-oral examination when the child reported at 17 months showed green intrinsic staining
of all the erupted primary teeth (chlorodontia).
Harder/deeper extrinsic discoloration and intrinsic staining
require various bleaching techniques.

The gel uses oxidising agents, most commonly hydrogen peroxide, on molecules causing intrinsic staining
- allowing these molecules to be converted into smaller non-coloured material.
Aesthetics is playing an increasingly large part during in-office discussions between the patient and dental professionals.8 Some patients may not need tooth whitening products that are effective against intrinsic staining
, but rather need an ongoing treatment to inhibit new extrinsic stain formation between office visits.
