Would recommend the kit 1000 times! Only used this non-peroxide teeth whitening kit for about a week and already made a massive difference! The kit is super easy to set up, takes about 5 minutes to mould the teeth guard, and the process is super quick also. All you do is squeeze a tiny line of the gel around the middle of the teeth guard and place onto the teeth. Then turn on the the LED light and you’re all done, leave on for 15-20 minutes. That’s how simple it is. Hasn’t made my teeth sensitiv...
