How to Whiten Teeth in 7 Steps!
Step 1 - Lets Practice First!
Before placing the thermoforming trays into the warm water it's a good idea to practice sucking the air out from the tray. When you suck the air out the tray, the tray will fit tighter due to a lack of air this is what you want to feel. This is the procedure you will use when you retrieve the trays from the hot water to contour the tray to the inside surface of your teeth. Do the same procedure with the other tray with your lower teeth. Once feel comfortable with you can start to heat a pot of water.
Step 2 - Hot Water
Boil a pan of water approximately 4" in depth so that the tray will be immersed keeping the tab above the water. After the water has come to a boil, remove the water from the heat and place the thermoforming tray in the hot water. Before you place the tray in the water do make sure it is not boiling. Leave the thermoforming tray in the water for 5 seconds. Please note the trays become very pliable at this point and will tend to stick together. While the trays are in this state avoid twirling them as it may ruin the natural contour of the tray.β
Remove the tray from the water and quickly place the tray in your mouth and around your teeth and suck the air out like you did in Step 1. Hold for around 10 seconds. Do the same for the lower tray. To avoid gel contact with the soft tissue (gums), take small scissors and/or nail clippers and trim your trays on the gingival line (teeth/gum line).
Ensure to brush and floss your teeth before applying the Gel to maximize the teeth whitening performance of the gel.
