In this video, Dr Jaclyn explores the role of teeth whitening lights and whether they actually make a difference in the whitening process. She begins by explaining that teeth whitening is a chemical process designed to lighten the natural colour of teeth, which is not the same as stain removal during a routine cleaning.

She clarifies that while professional scaling and polishing remove surface stains, whitening goes deeper to brighten tooth structure. Dr Jaclyn also addresses common misconceptions about light-assisted whitening, outlining when lights may be useful and when they add little to no benefit. Her guidance helps patients understand what really contributes to effective whitening and how to set realistic expectations for treatment outcomes.

Teeth whitening is often misunderstood as a simple cleaning, but it works differently. Unlike stain removal from scaling and polishing, whitening lightens the natural shade of teeth through a chemical process. Many treatments today include lights, but their actual effect varies. While some lights may speed up the process, the main whitening power comes from the gel itself. Knowing the difference between cleaning, whitening, and the role of lights helps patients make informed choices about achieving a brighter smile.
