How does teeth whitening work?
Each of your Igy White refills contains an active agent, which will break down the stains on and in the tooth.
The tooth is made up of 2 layers:
- the enamel on the surface is less permeable and more solid.
- the dentin under the enamel is more porous and therefore the stains that come in are often tougher.
The concentration and dosage of the igywhite gels have been studied in order to penetrate deep enough to neutralize the more internal stains (in the dentin) but also not to penetrate too deeply into the tooth and cause irreversible damage. The gels are dosed so as not to cause any sensitivity in the patient.
