It says to use once a day - forever? Or just until the teeth a whiter, then an occasional maintenance use?

The kit comes with enough whitener for one 15 minute treatment per day for 10 days. After that you would have to order more of just the whitener, since the trays can be used indefinitely. Most people recommend doing the whitening once every six months, or more often if you drink a lot of coffee or red wine.

We recommend using the product for up to 10 days, or until your teeth are as white as desired. Doing this treatment on occasion is typical if you only need a slight touch-up. If your teeth are heavily stained then you can use this daily until your teeth show improvement.

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.

Depends on the whiteness of your teeth. If they are white already, then you need to use more than a few strips to see results. However if they're not too white, you can see results after just one use

Obviously, it depends on how often you use it, however. I don't use it every day and it lasted a long time.

I don't recall the exact directions, but I used one every night for a week and then used one for 2 hours at a time every couple days for the remainder of strips. I think you're good as long as your gums are not getting irritated. Mine never did. I now only use one for 2 hours about once a month and it keeps my teeth looking great!

It's meant to keep tartar off the teeth over time. I don't think it's meant as a teeth whitening product. Sorry.

Wow are you serious? I leave mine on all night and take them out in the morning. Is this why my teeth sting when I do this?Typically about 7 hours. Is this wrong? I often get comments on how white my teeth are though.

Figure a half tube per upper/lower, so a full tube for both. If you are trying to whiten from yellow, use it once a week until you get where you like the color. After that use as needed for maintenance. Maybe once every couple of months.

I go for 6 month routine dental cleanings. My dentist hasn't said anything about damaging my teeth. It's pretty effective, so I don't use it daily.

use as long as it takes to whiten, or until you are happy with the whiteness. I leave on for an hour.

You could. But they do tend to cause pain... I've overused them & by that I mean one every other day. Unless you have a high tolerance of pain, I wouldn't recommend them. If you want a whiter smile faster, I would suggest the two hour strips every other day. Twice the whitening, maybe a little more painful but it's faster & takes a lot less uses.

You get about two or three uses out of each injector. You'll find that if you whiten for a week or two initially, you'll only need to whiten about every month after that.

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.

I use it fully about once every 2 years... But about every year I use it for 3 days to keep it up the whiteness.

I did it several days in a row when I first got them - don't remember how many.After a couple of weeks, I did a couple more....I don't want my teeth looking like they did when I was four years old.....I think older wrinkled faces with brightly shining pearly whites look odd and artificial.But, these stopped my granddaughter from asking "Papa, why are your teeth yellow?", and used now and then they eliminate the stains from coffee and other stuff I put in my mouth.Talking to your dentist isn't a bad idea....mine doesn't whiten his own teeth, but then he's 10 years younger than I am.....

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.

That's a subjective question. Depends on how much you use, and how often. If you use once a day, will last longer than if you use twice a day. There isn't as much in here as it appears, if you will notice the bottom is bowed inward. I don't recall how long it lasted, but know (as with anything) that is driven by how much and how often you use it.

Use every night for 1-2hours, in 1-2 weeks you will be able to know the difference on your teeth. Then you can just use once a month just to maintain the whiteness.
