Q: KIT: Molding the thermo-fitting mouth trays?

A: Bring 4 inches of water to a boil and remove from heat to cool for 6-7 minutes.

Submerge one of the mouth trays into the hot water for 10-12 seconds until tray appears soft. (Important: for best results do not overheat mouth trays)

Place the mouth tray into your mouth covering your upper teeth.

Close your mouth and suck all the air and excess water from the tray, creating suction between the tray and your teeth.

Gently push the tray against the front of your teeth by pushing against your upper lip.

Wait 12-15 seconds before removing the tray from your mouth.

Place the mouth tray into a cup of cold water for 12 seconds to complete curing process.

Repeat steps for lower mouth tray.

Q: KIT: Trim the trays to the correct size?

A: After molding both mouth trays, use scissors to cut any excess material from the tops of the trays at the gum-line. Trimming the trays at the gum line will avoid any possible tissue irritation.

Use scissors to cut the finger tabs from both trays.

Q: KIT: Whitening your teeth

A: Place a small drop of gel onto each tooth impression on the upper and lower mouth trays. (Do not overload trays; a little goes a long way.)

Put gentle pressure on the upper mouth tray by pushing on your upper lip with your fingers in order to ensure a tight fit. Do the same on the lower mouth tray.

Wear trays for approximately 20-30 minutes.

For faster results place the LED light in front of your trays to activate gel.

Once the time is completed, remove mouth trays and rinse out your mouth.

Rinse trays in lukewarm water and store in a clean dry place.

Repeat daily until desired shade is achieved.
