How long should they be left in and how often?

Oh and maybe like once every other month for use...if your teeth arent super yellow once every couple months should be fine. I had a yellowing tooth on my bottom row (slightly crooked on the bottom) its all white now.

I keep the trays in around 30 minutes. I do it daily for a week. It might take 2 weeks depending on how white you want tour teeth. I also coat my gums with petroleum jelly to prevent burning them. I try not to drink coffee or red wine. If I do, I put the trays in that night.

I use a brand of bleach called opalence (I think thats how you spell it) I leave it on for an hour and then brush lightly so I dont irritate my gums or anything. The brand that came with the impressions I havent use it yet but im sure its the same......same strength. I suggest puttin vaseline on ur gums before hand. If you think about it, if you go to the dentist for impressions they cost way way more than this that comes with the bleach and the impressions. You have a good deal with this. I hope I answered your concerns :)

At least a few months. I use them too quickly to find out, but I used a leftover box after about three months and they were good as new.

They have the expiration date printed on the filter package. Usually a few years. I usually keep them about 2-4 weeks after opening, depending on the spray environment. I keep them in an air tight box when not in use. You can also use zip lock bags; otherwise they will become contaminated. If the environment is not adequately ventilated the useable time can be greatly reduced also.

It depends on the intensity of the conditions. I've been able to reuse them many times, after allowing to dry out. But in very humid conditions or underwater, I've discarded them after a day or two. You'll see them start to come apart when it's time. Also make sure a corner of the insert doesn't get caught in the case closure, it's pretty easy to accidentally do.

I'm thinking for a week or until they look dirty. You have to take them out in the morning and put them back in the case. Don't just put them on your night table to collect dust.

They last for a long time. I have had mine for over a year. I bought two bags and consolidated them all into one bag. As I use them I put the used ones in one of the nets (bags) it came in and toss them in the wash. That way I always have enough.

There is no indicator. I leave them for about two hours. You can leave them overnight but it does not make a difference.

Well, I keep them after opening in a ziplock bag and I think sometimes it's 6 months or more before I use them all. Sometimes I put them in the refrigerator in the ziplock bag. Once you've reconstituted them with water however I'd use them within a few days.

Twice a week. I would not leave them on more than 20 minutes first time. I left mine on 30 minutes twice a week after I knew my teeth would not hurt. If you left them on to long believe me you will know.

I keep them in a cabinet unopened until I am ready to use them. Once opened I store them in the refrigerator in a closed container.

I keep mine in the refrigerator. They should last a few months that way. They are delicious!

It depends on how you store them, and how much of a perfectionist you are. I vacuum seal them in quart mason jars as soon as I receive them, and store them in a low cool cabinet. They are fine for 6 months.

I keep mine in a cabinet. As long as it's dark and dry you should be good. They won't last for extended amounts of years but at least 1 yr they are definitely good. Hope that helps :)

The manufacturer recommends discarding after three months, so I would follow these directions, however the frequency of use will determine ultimately how long it will last. Mine has lasted at least three months. I hope this helps.

As per manufacturer recommendation, the safe should be left open for at least 15 minutes once every two weeks or twice a month. In addition, the safe comes with a medium sized bag of silica gel so you can leave it in along with your documents.Thanks

I am guessing 3-4 hours but I am not sure. I usually put them in at midnight and they are ready to go by 6 am or so.

I usually change them about once a month. I rinse them off when I change the fountain once a week. Sometimes I get longer.
