SmileDirectClub Teeth Whitening Kit with LED Light - 4 Pack Gel Pens - Professional Strength Hydrogen Peroxide

made my teeth kinda sensitive . but works soooo good ! 10/10

My teeth were moderately white but I had some staining because I drink coffee everyday. But this made my teeth so much brighter in just 4 days. Absolutely no pain and I have sensitive teeth, unlike whitening strips where I have pain from one strip.

The gel did whiten my teeth a few shades...I don't know if it was as much as they advertised it would, but I've seen a definite improvement. The picture shows progress from day one til end of 4 pens treatment, which they say it should last about a week. It lasted me longer (about 11 days), maybe because at first I didn't use enough gel. Didn't experience any sensitivity until at the end of the treatment very light sensitivity. I wasn't happy with the accelerating light .... It's very bad quality it broke within a week,the light goes in and out (mostly out) which became very frustrating very quick. I had to buy another brand accelerating light which seems to last longer so far. If I had to do it again I would buy just the gel pens treatment and a different light from the beginning. They need to work on making a better, longer lasting light. Maybe the adaptors for different phones is the problem. They need to come up with a more reliable connection. I wish I could just plug it in with a cable....like a USB cable, not into a phone. Overall grad I tried it I feel more confident with my smile. Note: Top teeth are crowns bottom my natural. So it does work on crowns as well!

So easy and quick to use. Giving one as a gift this Christmas.

This is my 1st jab at the LED teeth whitening. The price is a little more than I would normally spend, but the reusability was the main appeal. There are some plus & minuses worth mentioning. To begin, I thought I ordered the type that you can use once per day for 10 minutes - Amazon had it listed as a separate product from the 5 minutes twice per day, but the instructions on the box I received indicate to use for 5 minutes twice per day. No biggie, I'm just a busy lady & I was hoping for a once per day product. Overall, I think the whitening worked fine. (Again, I don't have much to compare it with) I was actually able to get 2 one-week uses out of the gel pen included in the box. Maybe I'm not using enough, but that was kind of a bonus, & I like that I can purchase refills online as well. I couldn't really find info on how often it's safe to use this product, so I'm just beginning my 3rd treatment this calendar year (and also since purchasing) in mid-November. My main issue is with the length of the charge. The directions indicate that 1 full charge should be enough juice for a one-week treatment. This was accurate for the first use, but it had to be re-charged mid-week during the 2nd use, and now I have to charge the mouthpiece after every single use for the 3rd round. I've been super careful to keep the base of the mouthpiece dry when rinsing with lukewarm water, just like the directions say, & I use low water pressure & dry it thoroughly before storing back in the the charging cradle. The mouthpiece shut off after less than a minute on the second day of the current round, so I had to miss that session since I didn't have time to wait for it to charge. I know a lot of reviews complain about the power button being too touchy, which I agree with, but that wasn't the issue in this case. It worked fine after it charged for a while. All in all, it does the trick if you have time for the maintenance & are prepared to charge the product often.

I tried 3 kits and this one is the best by far and I plan to keep buying this one moving forward. The gel brush lets you get into the crevasses of your teeth. Previous gel kit I tried didn't have a brush so it was hard to spread effectively. Also the strips don't effectively cover the crevasses of your teeth. This one does it well. Only 5 minutes at a time is nice. Previous kits I tried was 15-30minutes. This 5 minute kit lets you just do it quickly during your morning & nighttime routine. The light attaches to your phone which is nice since I always have my phone on me. My teeth are looking noticeably whiter after just a few days of use.

I’ve been using this brand for years now and it absolutely works, even my dentist asked what I used because he was impressed with how even and white my teeth were. I don’t even use it weekly now but a touch up every few weeks keeps my teeth perfectly white. The whole brand is great including the tooth paste and extension pen they make. I’ve tried other products over the years including the Crest 3D white but it doesn’t even come close to the results you’ll get from this brand. I promise it works amazingly and this is coming from an avid coffee drinker and former smoker. It’s also super gentle on your gums as well and I’ve never once experienced any discomfort or sensitivity after using it. Also the fact that it can plug into your phone is super handy because you can toss it on and go about your morning routine without having to be plugged into an outlet, the device is also super light weight since there’s no bulky battery pack attached to the end.
