It is important to have custom mouthpieces made to whiten your teeth properly. The boil & bite trays, and strips that are bought from a store causes spotting on the teeth (this is due to the teeth whitening gel not being evenly distributed on the teeth because the mouthpieces and strips are not snug), allows saliva to dilute the whitening gel, and cause extra sensitivity (because the mouthpieces are not cut out along the contours of your teeth and allows the gel to sit on your gums).

It is vital that a good impression is taken. A good impression determines if your trays will fit right and snug. This is why Professional Teeth Whitening uses an impression material called vinyl polisiloxane that is not runny, does not gag you, and takes a far superior impression than an impression taken using alginate (impression material that a typical dentist uses). Alginate is 10 times cheaper, runny, gags the customer, and takes an inferior impression. Professional Teeth Whitening provides you with this superior impression material so you do obtain a good impression and so your mouthpieces are of the best quality.

1.	READ ALL INSTRUCTIONS PRIOR TO PROCEDING

2. Take a ball of gray putty out of the gray container and a ball of blue putty out of the blue container. With the tips of your fingers, mesh/knead them together until they become one color (do this quickly before the material begins to harden).

3. Roll the meshed putty into a 2 inch long hot dog shape and place it into the tray. Mold the putty so it's evenly distributed throughout the tray.

4. In front of a mirror or a friend, place the tray in your mouth and position your upper teeth between the front two walls of the tray, making sure your front teeth don't scrape the inner wall of the tray.

7. Inspect the impression, making sure that it captured the tops of your front teeth past the gum line and that the impression is not distorted. If the impression isn't good, re-do steps 2 to 6 after taking an impression of your bottom teeth. To redo an impression, remove the putty from the tray and re-use the tray with a new putty mix.

9. Place both impressions in the preaddressed envelope and seal the bag. Place your personal information card into the small pouch on the outside of the pre-addressed envelope and mail it to Precision Dental Arts.
