How does teeth whitening work?
Active substances that bleach the teeth include gels and serums that are used for whitening teeth. Most generally, this is either hydrogen peroxide or peroxide carbamide. They break down stains, making the colouring less concentrated and whitening the teeth.
In other areas of your mouth, those two compounds may be harsh. This is why protection for gums and lips is added. To prevent patients from burning their mouths, items intended for home use have much lower concentrations. This also suggests that these consequences would not be as evident as clinical treatment.
LED and other forms of lamps can be used to help the operation. No, they’re not whitening their teeth. By making the active ingredients break down faster, those devices simply speed up the process.
