Pro light dental whitening system
A professional light whitening system combines a peroxide gel with a dental light, after checking teeth, gums, fillings, and sensitivity.
The short answer
A light-activated dental whitening system uses peroxide gel under dental supervision, with the light serving as part of the product protocol rather than replacing the gel.

How does peroxide gel break down tooth stains?
The gel contains a peroxide compound that breaks down stain molecules within enamel and dentine. Before treatment, the clinician checks for decay, gum inflammation, exposed roots, cracked teeth, and restorations that will not bleach.
What happens during a light whitening appointment?
A dental visit normally includes shade assessment, examination, gum protection, controlled gel placement, light exposure according to the system instructions, and post-treatment advice. Tell the clinician about sensitivity, pregnancy, restorations, and previous whitening.
When should teeth be examined before whitening?
Have an examination before whitening if teeth hurt, gums bleed, roots are exposed, or a single tooth has darkened. Contact the provider if severe sensitivity, gum burning, or an uneven result develops after treatment.
Which gel and light protocol will be used?
Ask which gel and light protocol will be used, whether existing fillings or crowns will match afterward, and how sensitivity will be managed if it occurs.
Frequently asked questions
Will it whiten crowns?
No. Crowns and fillings do not bleach like natural tooth structure.
Why can sensitivity happen?
Peroxide can temporarily irritate dentine pathways and the pulp, especially when teeth already have sensitivity.
