How does SunnaSmile teeth whitening work?

SunnaSmile uses a professional-grade LED light system combined with a natural whitening gel to gently lift stains from the tooth surface. It brightens your smile safely — without harsh chemicals or sensitivity.

How long does the treatment take?

A full whitening session typically takes just 30 to 45 minutes, making it an easy add-on to your self-care routine.

How many shades whiter will my teeth be?

Results vary, but most clients see an improvement of 2–8 shades whiter after just one SunnaSmile treatment.

How long do results last?

Whitening results usually last 3 to 6 months, depending on diet, lifestyle, and oral hygiene. Touch-ups help maintain brightness.

Is SunnaSmile safe for sensitive teeth?

Yes. SunnaSmile is specifically designed to be gentle on enamel and safe for sensitive teeth, using only natural, non-abrasive ingredients.
