How long until I see whiter teeth?

Banana White says the system whitens 1-2 shades after one use. Most users see the clearest change after using it 3-5 days in a row, as the brand recommends.

How often do I need to charge it?

The light lasts for 1-2 full 25-minute treatments per charge. Charge it overnight; the light flashes while charging and stays on when full.

How many treatments are in the kit?

The kit includes 30 treatments of whitening gel. That covers an initial run of 3-5 days plus months of maintenance at 2-4 sessions per month.

Is it safe for sensitive teeth?

The gel uses carbamide peroxide, which is gentler than hydrogen peroxide but can still cause sensitivity. The built-in red light therapy is intended to reduce tooth and gum sensitivity during sessions.

What is the difference between the blue and red/blue modes?

Use blue light alone for the first 15 minutes, then tap the device twice to switch to red and blue light for 10 minutes. The full session is 25 minutes.

The kit includes the wireless LED tray device, a charging cable, and 30 treatments of whitening gel. Check the listing for the exact gel format and any extras.

Our take on the Signature Wireless Kit

The Banana White Signature Wireless Kit is an at-home teeth whitening set built around a cordless LED tray. The tray has blue LEDs on top and bottom plus red light therapy, which the brand says helps reduce tooth and gum sensitivity. The kit includes 30 treatments of professional-strength carbamide peroxide gel. Sessions run 25 minutes: 15 minutes of blue light, then 10 minutes of red and blue.
