Lost $250 on a whitening kit that did nothing for my molars
Bought this LED tray set in March from a mall kiosk in Austin, promised 5 shades in 2 weeks. My front teeth lightened a bit but the molars stayed yellow, so I basically paid for a flashlight. Anyone else find that these kits just skip the back teeth no matter how you position the tray?
Sounds about right. Those LED trays are basically just tiny tanning beds for your two front teeth while your molars sit in the dark like they didn't pay rent. I had one where the gel only touched the front six and the back ones stayed the color of old coffee. You keep shifting it around hoping it'll reach back there, but the tray is shaped like a mouth guard for a toddler and just gives up past the canines. Next time save the cash and grab a cheap whitening pen for the front, your molars are backstage anyway.
