What's the duration of the whitening? Does your teeth reverts back to it's original color after a period of time?

It has been about 8 months since I whitened my teeth, and I still feel that they are whiter than they were before I did it. I would guess most people would probably whiten every 6 months to keep their teeth looking white at all times.

The whitening lasts several months. Eventually your teeth start to show the more stains again, but I think this is the case with all whitening strips.

They make no medical claims but I can tell you your teeth will be very white after using. I use it once in a while and wait till it at about 1/2 strength. Never swallow it just rinse or brush with it.

Hi Emily, I bought it and also the whitening for 7 days that each strip it's 30 min, I can tell you that the 1 hour it's stronger so you use only one or two and it's really work.. It's better bc it is stronger .. I put it less than 1 hour bc my teeth wasn't so bad.. It is depend how white you want it, hope I helped you.. And sorry about my English I'm not American ... :)

The whitener is effective enough for me to use once per day for 2 weeks. Depends on cases, people suggest using it every 6 month.

I started seeing noticeable results after about 3 times of using the strips (I was using them every other day or so, so it took about a week). By about 5-6 times of using the strips, my teeth were definitely the color I was hoping for. If you used them every day, you could get them bright white in a week I'd guess.

At first I did for about 2 wks then cut back after my the stains on my teeth went away. After you use them a while you will be able to gauge how often you need them.

I leave it on one hour but I'm doing touch up only, not original whitening. My original was done in the dentist office. I now touch up after each time I get my teeth cleaned. There is an instruction sheet with the package.

You can start it for 2 minutes or 2 minutes 30 seconds. It vibrates every 30 seconds, so that you can brush an equal time for top/bottom/right/left. The optional extra 30 seconds enables ultrasound said to whiten your teeth.

First off, it's not in your mouth all that long unless you suffer from dry mouth. The color that it 'melts' away to is red. I've seen red after brushing my teeth in the saliva but never have I ever had staining on my teeth from these. You really shouldn't worry about this as you're supposed to let it fully dissolve under your tongue, not anywhere else in the mouth. Anywhere else in the mouth would NOT allow the B12 to be absorbed properly and would be a waste of product and money.

It's been at least six months since I last used this product. But, it seems to me that I got at least a week out of each tube. My dentist's office recommended only using a very small amount (the tip of a pencil) in each front tooth space of the retainer and mouth guard at each use. I reached the maximum amount of whitening quickly. The amount of whitening was determined by how white the existing crowns were. I bought the first four syringes and then bought a second set of 4, but only used one syringe before the dentist told me I had reached the right amount of whitening. The first set of four probably was enough. It's been at least six months since I last used this product. But, it seems to me that I got at least a week out of each tube.

I want to add that I do it for about 4 to 5 days. For best results, use it right after a dental cleaning. Once your teeth get whitened, you can use it only periodically when you feel it is necessary or again after your next dental cleaning. Hope that helps.

The light is supposed to help with the whitening process as used at other professional establishments. You suppose to keep it in your mouth for at least 10-20 minutes after the treatment. The treatment isn't supposed to dry on your teeth because it's supposed to be applied only to the tray then insert the tray in your mouth. Be careful not to add too much treatment because it will burn / irritate your gum on contact. I hope this helps.

If you have sensitive teeth, you might start off keeping your bleaching tray in only for 2-3 hours the first time and increase if you can tolerate it. That's what I did. It takes a little longer to get your teeth whiter that way but you won't feel the discomfort.

No may restore them to what they were. But doesn't whiten them any more than when they were put in

You mean your teeth didn't get any color on them? It usually takes me a while to get the color off. Better yet, just go to Ora wellness website for a good brushing technique and you're not going to need these anymore.

After 2 hours it stops working. It doesn't continue to whiten for 8 hours, that would be dangerous. I accidentally fell asleep on the couch with them on one day, but I really don't recommend sleeping with any type whitening strips, only bleaching trays. These adhere pretty good, but I still personally wouldn't sleep with them on.

It did whiten them but the bulb burned out after one use. No adverse effect on the gums at all. It's just uncomfortable .
