It works eventually
My dentist sells this exact device for three times the price, so this seems to be a good value. It took me a while to get it up and running. The device had to be charged overnight before it lit up. I was worried I had a dud because the power light was on at first, but the mouthpiece wouldn’t light up. It worked at full charge, though. The whole process is pretty messy. You apply gel to your teeth, then insert the mouthpiece for 8 minutes. You repeat that four times for one session. As you wear the mouthpiece, your mouth fills with saliva and you might start drooling, so keep a paper towel handy. After 8 minutes, you take it out, reapply the gel, then do it again. The directions didn’t say how much gel to use, but each little gel capsule is supposed to be one session. I had a lot left over, so the next time I put on more.<br /><br />You start by checking the whiteness of your teeth on a little chart, the check again after each session to mark your progress. I started at a 7 and am at a 4 after three sessions, so it does work.<br /><br />However, the instructions say not to put the gel on the gums, and I’ve noticed that my teeth are lightening on the tips more than at the base. So, on the last session I applied the gel right at the gum line to balance the effect. Today, my gums are sore, so I understand why they say that, but what else am I supposed to do to get the whole tooth white? Anyway, I’m taking a day off before doing my next session.<br /><br />I have sensitive teeth, and this has not really caused any serious discomfort. I recommend this device at the price I got, which was around $110.
