How does an LED whitening kit lighten teeth?
An LED whitening kit uses a light device with peroxide-containing gel; the gel performs the chemical whitening.
What is an LED whitening kit designed to do?
This is an at-home tooth-whitening system, not a brush or gum treatment.
How can you use an LED whitening kit safely?
Follow directions, keep gel off the gums, and have decay, cracks, restorations, and gum disease checked before use.
When should you seek advice before using the kit?
Ask for assessment before use if you have untreated cavities, inflamed gums, exposed roots, or marked sensitivity.
What should you ask before choosing a whitening treatment?
What is the likely cause, what examination is needed, and which treatment addresses it?
