What you have to remember is that you want to get a good impression of your teeth so that you don't waste the teeth whitening gel.
Also the finished impression should be a good fit, this means that all the teeth are covered by the impression but any surplus that reaches over to the gum should be trimmed off. The reason for this is that we don't want any gel to work on the gums as this is one of the main reasons that people report sensitivity after using teeth whitening. The surplus is very easily trimmed off with a pair of sharp scissors.
The thermo forming trays are very pliable and you should practice putting either the top or bottom tray in your mouth and trying to suck all the air out as this is the action you will use to make the finished article. When you actually fit the tray you will have to work quickly as the trays soften in a matter of seconds in the hot water. Make sure that you have everything that you need to hand so as not to waste time.
Now working with one tray at a time, bring the water to the boil in a pan, let the water just go off the boil and immerse one tray into the water. You do this ...
... by holding the tray with the tab which is at the curved top of the arch. Do not let go off the tab and only hold the arch in the hot water for a couple of seconds. When you withdraw the arch it will be very floppy so take care not to shake it, just place it straight over either your bottom or top set of teeth and with strong sucks, suck all the air out. This should make a good impression of your teeth. Now do the same with the second tray but place it over the opposite set of teeth and draw the air out. As mentioned earlier if there is any surplus, trim it off before using the trays. You are now ready to start using your teeth whitening gel and getting the lovely white teeth you are hoping for.
