MySmileTeeth Whitening Pen 30+ Treatment Enamel Safe Tooth Whitening Gel for Teeth Sensitive-10 Min Fast Whitening Teeth-Helps to Remove Stains from Coffee, Smoking, Wines-Mint Flavor

Easy to use. Saw whiting results upon first application

I have used this for 4 days straight and my teeth has gotten whiter for sure. I will but the kits for my family and continue getting the strips. This is a wonderful product. I have not seen my teeth so pretty in a while.

I just got it so I can't really rate it but I do like the product it is not messy and easy to use so all pluses on that I just can't rate on how it works as far as how well it works yet. Hopefully it does great.

Arrived quickly and seems to be working. I have very sensitive teeth and this has no zings!!

I have been using the Snow whitening system for several months now prior to purchasing this product. And while it has done an excellent job in whitening my teeth the LED light that comes with the wired system has to be attached to your phone in order to be powered. This is very limiting in that you have to have a cord in your hand for 20 minutes. You can't get up and do things as easily as you normally would because usually the phone has to be in your hand. Snow does have a wireless LED light system but it's quite expensive and you have to buy it with a kit. So I decided to look for another option.So I looked on Amazon and I found the MySmile rechargeable teeth whitening LED light. I thought to myself, "this is excellent!" It's actually rechargeable and has a little case with it.It actually works really well in terms of the recharging and how it fits into the case. The problem I have is that it is much more uncomfortable than the Snow system LED light.For some reason this thing cuts into my gums a little bit and I have to bite back on the unit in order for it not to cause my gums any pain.While I am getting used to biting it in a different position than you normally would with any other mouthguard, I would prefer not to have to do that. It's a problem that I never had with the Snow system. However, because this thing is so much more practical in that I don't have a cord it's either this or be connected to the power cord of the Snow system. For that reason I have to say that this thing is very useful but the design is slightly flawed in that it cuts into the gums a bit.If it didn't give me any pain it would be by far the best LED whitening light on the market. They really should think about doing a redesign that doesn't cut into the gums so much. If they would have done that I would have given this thing five stars easily.

Helped remove stains

Recommended. It works well.

One pen won't work - I turn the bottom to push the gel up to the brush at the top over and over. Nothing ever comes out into the brush. The one pen that does work, I had to turn the bottom about 20 times to finally get the gel to come to the brush at the top. This makes me wonder just how much gel is in the container. There were no directions regarding how to prepare your teeth for the application of the gel. Nor were there directions on what to do when you've finished with an application. I'm returning the order for a refund.
