Is Lumira safe for sensitive teeth?
Yes. Lumira uses an enamel-safe PAP+ formula that whitens without the sensitivity or gum irritation common with peroxide-based kits.
How fast will I see results?
Most people notice a visibly brighter smile within 7 days of daily 10-minute sessions, with best results after about two weeks.
How do I use the LED kit?
Apply a thin line of gel to the mouth tray, insert it, and turn on the LED light for 10 minutes. Rinse and repeat daily for 7–14 days.
How often should I whiten?
Run a full cycle to reach your desired shade, then top up once or twice a week with the gel refills or purple serum to maintain it.
Will it damage my enamel?
No. PAP+ is designed to be gentle on enamel while still lifting stains effectively.
