Are led teeth whiteners safe
LED whitening results and risks depend mainly on the gel, exposure, tray fit, and the condition of your teeth and gums, not the light alone.
Are LED teeth whiteners safe for your teeth and gums?
LED whitening results and risks depend mainly on the gel, exposure, tray fit, and the condition of your teeth and gums, not the light alone.
How do the LED device and peroxide gel work together?
An LED device emits visible light near the teeth while a product may contain peroxide gel. The light does not repair decay or change the shade of fillings, crowns, or veneers, and poorly fitting trays can expose the tongue or gums.
What should you check before using an LED whitener?
Check the ingredient label and follow its exposure instructions exactly. Have a dentist inspect cavities, cracks, enamel wear, gum recession, and existing restorations before choosing a home system.
When should sensitivity or gum changes prompt dental advice?
Stop if you develop marked sensitivity, gum whitening, burning, ulcers, or pain, and seek dental advice if symptoms persist. Do not use whitening over untreated decay or unexplained tooth pain.
What should you ask about the light, gel and restorations?
Ask what the light is intended to do, which gel is paired with it, whether your restorations can match, and how sensitivity will be managed.
