How long does the whitening last?

I've been using Go Smile for years. I use the touch up tubes on an average of three times a week. My teeth maintain a white look. I tried the Go Smile sticks that you can use on a daily basis but the product runs out quickly or doesn't really work at all in terms of longevity.

It's the actual whitener. You do it for 5 minutes a day 7 days in a row which is so much better than the strips. My teeth actually got whiter after the first two days

It is recommended that you use these every day until you finish the box. For faster whitening, use them twice a day. The directions suggest that you may use up to 2 boxes per year. I find that I have reached my "brightness goal" by using one box. I keep extra boxes available and will use them "daily" for a few days when I begin to notice that my smile is losing it's brightness (I can see this most easily in photos.) That usually does the trick. If you experience sensitivity (I have not) it is suggested that you discontinue use for 2-3 days.If what you are asking is, "Can I use these daily 365 days per year?" I don't see that suggested on the instructions. It is recommended that you use these every day until you finish the box. For faster whitening, use them twice a day.

I like the 14% Day White better than the Night White, because I don't like sleeping with bleaching trays in my mouth. I get good whitening from the Day White formula. I use it twice a day and leave it on my teeth for 30 minutes, each time.

I had my original whitening done with a product from a dentists office 20 years ago. This is pretty much the same thing you get from the dentists office now, except so much more cheaper. When I first did mine, it was for two hours every day. I think it's just a matter of how much time & how often you want to dedicate to it :-)

I've experienced teeth whiteneing with this product and it has not caused any sensitivity.

Depends on how often you whitening - it's stronger than over the counter products especially considering the cost.

Only comes with 1 whitening gel syringe and depending on how much product you put it'll lasted me 3-4 weeks & that's 4-5 x a week

In my opinion, those work better than the 2 hour strips. They do about the same whitening, it's just that you don't have to go through having them in your mouth for 2 hours

Every time you put the whitening trays in...I used once a week. You have to put the gel in the trays...put those in your mouth...and then put the light in your mouth over top of the trays...a bit awkward to do.

Not 100% sure but, I believe it would lighting you teeth a light shade of gray. Your teeth may be naturally gray and therefore I would recommend getting you teeth bleach by a dentist OR get the strongest opalescence at 35% and do it once a week for no more than 30 minutes.

yes....it is four cycles of 30 seconds (2minutes) for regular cleaning. The whitening cycle is the same four 30 second cycles with two additional 15 second cycles at a different speed or vibration.I have not tried the sensitive setting

About two months, like it says. The face wash lasts a little longer, the clearing toner a little shorter.

It does not whiten. It's suppossed to help build up enamel and dentin. I have used it and I am pleased with the results. I whitened my teeth to much and they became very, very sensitive. I stopped whitening for 6 months. I used this product, along with toothpastes with xylitol and Novamine. My teeth are much stronger, bad breath is limited and sensitivity is lessened. Hope this help.

I wouldn't say whiten, but the creme will fade away any spots or marks your trying to permanently get rid of . . .

The product I received does not show an expiration date, but I have had some that was three years old and it still whitened my teeth very well.

You could see immediate whiteness of the teeth after a few uses...it all depends on how white the teeth are in the beginning. Keep in mind these Crest strips are just for a 5 min. gentle routine daily. Good luck!
