Opalescence

Opalescence teeth whitening system.
I was givin the little things ... Sering How do I use?

brush your teeth before. apply a thin line on the front of your molds only (you do not need to take back, no one will see the return of your teeth anyway) and put them on. I want to put them in at night before going to bed and sleep through the night with them, but you want to try them first for about 1 / 2 hour or two the first case in your teeth are sensitive.

Have you got this from a dentist? They should have explained how to do everything, but anyway. . .
You need to have customized trays that match your teeth. You must leave a line of gel in the front teeth in the bins. There are usually indicator lines to guide you to the amount to use. You do not need to go all the way to the back teeth, I usually recommend going to the first molar. Place the tray in your mouth and press the tray onto the teeth to ensure it is correct. If there is a residual gel that oozes the plateau on the gums, make sure to wipe it, because it causes irritation of the gums. Do the same with the other side. Leave the plates in at least one hour, up until the night, which depends on the strength and your level of sensitivity. You should see results within the first days, using a maximum of 14 days. After this time, you should be quite white, otherwise I see your dentist and see what they recommend next, more or whitening gel more.
Good luck!
