Does it whiten both the front & back of the teeth?

I don't believe so. Your mouth is closed on the mouth tray, so light only penetrates the front where you put the gel.

Yes it works as long as you fill the tray to the back. I am not using mine anymore though. I found it more time consuming than I had planned on.

I just answered but wanted to say one more thing. Your rear molars do not really need to be whitened, only the front teeth people can see really. So, if your mold covers all visible teeth, you're good to go.

No, when the batteries went flat re whitening gel still works, but the light makes the formula work REALLY fast. Careful not to get it on your gums coz it can burn, especially if you have sensitive gums

no it does not - it is suppose to whiten the white of your eyes and it does not do that either!

Yes if used regularly this toothbrush will whiten teeth and promote healthy gums. Best too brush Ive ever owned

No, just the front. There are two strips in each treatment packet - one for top and one for bottom. They do a great job in a gentle fashion. I've never before been able to take advantage of whiteners because of sensitivity.

Hi, I have crowns too but mine are more in the back of my mouth with the exception of one which is on the side so I really can't answer as to whether they will whiten your crowns that are in the front of your mouth. I have not had one bit of sensitivity to them. All I can say about the crowns is for you to try them or contact Rembrant and ask what their success rate is using their strips on crowns for whitening and if you decide to do this, will you post your results for me to see? Thanks!

Yes they do work for front and back. I've had them over a year and they still look new.

It didn't damage my teeth, but it also did not make them whiter. In my opinion,purchasing the product would be a waste of your money.

Says it whitens but I don't see it, but I have very white teeth. It excels at getting between teeth.

No it doesnt at all. I have a few spots that are brilliant white... Like as white as teeth can get, but closer to my gums it didnt whiten at all. I dont recomend these.

I don't know since I also use a whitening toothpaste and whitening gel with trays. I bought the flosser to get deeper into the gum pockets. not remove stains.

No, it can clean the back. For the amount you pay, it is more than worth it. The # of cavities and trips to the dentist have decreased thanks to this toothbrush.

I haven't found it whitens my crowns but maybe i need to try it again. I don't believe GLO says it whitens the crowns, only natural teeth.

No, but you can wear it on your top teeth or bottom teeth and it hits different places.

It did mine! I even took pics and had my husband look at them. I had him tell me if the teeth in the pictures looked different, and if so, which pic had the whiter teeth. Even he could see a difference. I broke open the capsule, dipped a wet toothbrush in the powder and brushed for 5 straight minutes.

I was not aware of the two versions until just now. However, I used the regular one. I have pretty sensitive teeth and did not experience any problems whatsoever. Now that I know about the speed whitening product, I will try that one and post my comments shortly thereafter. I am very pleased with the results I have achieved with the regular version. Saw results after one use. I used it the first time for 20 minutes. I used it every day for two weeks, and then continued to use it for about 3 times a week after that. I have recommended it everyone!
