I got a teeth whitening kit... not the strips but the gel that you apply onto your teeth with a brush and let it sit for a while. Problem is that the kit doesn't give good instructions at all!

How long should I leave it on? And after applying, what do I do? Do I make sure that my teeth are exposed and I'm not allowed to close my mouth, or am I allowed to close my mouth? I thought that if I closed my mouth, my lips would rub the gel off?

Usually you apply and let it sit for 30 minutes and just rinse your mouth with water. You can close your mouth!

You can close your mouth. :)

Look up the brand on the internet.
It should give instructions online :)

That one doesn't work too well.
Get crest night effects. It's great.
You apply the gel before you go to bed after you have brushed your teeth. It will dry and turn in to a wax. In the morning you wipe it off and brush your teeth. You'll see a difference is just a few days. (I use it once a year)
