Does longer time on the teeth mean deeper penetration better whiteening?

I left mine on the recommended time and got good results. Not sure if leaving them on longer will make a difference.

I don't think so. Plus, I think the teeth get so sensitive after longer applying that you would want to avoid it. Sometimes I get some moderate dull pain in the teeth during the night. So don't overdo it.

I leave mine on for 1 hour, and don't eat anything for 30 min. After I take them out. I have not even used all of them because my teeth got as white as I wanted already. I did not want extremely white teeth though.

Hi, I didnt do it in consequetive days, but spaced it out over 2 weeks as the gel was making my teeth sensitive...maybe doing it for 7 straight days might have been better as far as results.

i think its supposed to accelerate the process but im not sure. I stopped using it after 5 days. I honestly do not believe that light does anything because if it did, i think special eyewear would be necessary. My teeth whitens without it.

No negative effect but the product did not perform as I was led to believe it would. I really could not tell any difference in the whiteness of my teeth after using the product.

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.

You will have to do research on that. I do know MSM can whiten teeth w/prolonged use & also helps to decrease gum inflammation by rinsing with the dissolved crystals 2 -3 times daily or by repeatedly rubbing the crystals onto the inflamed gum tissue. If it whitens teeth it can do the same for skin color. However, how much you will need to use & the duration, you will have to look up. Hope this helps.

My experience was that it did not show a discernible difference in the whiteness of my teeth which I would judge to be moderately stained. From the description of the product I expected to see a noticeable increase in whiteness and I saw no difference.

Certainly! I would recommend Biotene Toothpaste after whitening because it helps close the pores in enamel while providing plenty of fluoride and it it more gentle than the regular toothpaste.

No they don't. For those of us with a wide smile, use both a bottom and top strip for coverage of all the top teeth, and do the same for the bottom.Yes, I use twice as many strips, but it's worth having all my teeth white. : DNOTE TO MANUFACTURER: MAKE A LONGER STRIP FOR FULL COVERAGE PLEASE : D

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.

Depends in what you're addressing. Fine lines & wrinkles...a .5 or .7. Deeper penetration addresses scars & the like, so my research indicates.

Yes, in addition to the normal cleaning mode it has a deep cleaning, sensitive, and whitening modes.

honestly I am sure that's whats supposed to be the difference but I really don't see much difference in this and strips I didn't see much of a change , maybe just my teeth ?? maybe they are as white as they can get I dont know good luck :)

I've used it with my clinical strength (from dentist) whitening gel and it seems to speed up the process. i.e. it doesn't take as many treatments to get the results I'm looking for.

I agree about the sensodyne. I found that if I used the strips after I had been using the Crest 3D whitening toothpaste exclusively, I got sensitivity. So I suggest using a sensodyne type toothpaste for a week or more before using the strips. Then when you are done you can go back to whitening toothpaste. Both the strips and the 3D toothpaste worked great though.

It depends on how white you want your teeth and how much coffee, tea, wine, and other staining food and drink you consume. For the first time you use a whitener, I would recommend doing a full course of 10-14 treatments over 2 to 4 weeks depending on how well your teeth handle the sensitivity (which is temporary and can be managed by taking days off in between treatments if you are sensitive). That initial treatment course will dramatically whiten stained teeth (getting a cleaning at a dentist's office prior to this is a good idea too). Afterwards, you will have to touch up every 6-12 months depending on your eating and drinking habits. You can also use once a week to once a month as maintenance.

Bleached is better over time. Sooner or later the bleach teeth will darken and look norma . I order bleach all the time. I tried normal did not like it. Normal color got darker to soon. Cheer.
