before, during, and at the completion of Whitening.
This is a very critical step in the total success of your whitening treatment. The first thing you will want to do is download the tooth whitening  shade guide provided here on this web site.  We have provided you with a guide that has 20 shades.  You might be asking yourself why 20 shades.  Most dentist have a colored ordered shade guide for teeth that they use to determine shades on their patients. Additionally almost every dentist in the U.S. also uses a VITA shade guide to match their patients teeth for caps, veneers, and tooth colored filling. The tooth whitening shade guide that you can download here and print goes from the very dark  shades  on the dentist COLOR ORDERED SHADE GUIDE to the whitest shade available to dentist for professional tooth matching. This way you are certain to find your starting shade  before you begin your treatment. Below is a list of steps you should do to measure your progress during your treatment. .
1. Save  the tooth whitening shade guide  to your computer and print it on Matt or Gloss paper. Do this from the LINK below to get the best resolution Photo. Once you print your guide cut it with sissors about 1 mm above the edge of  tooth number 1 all the way to tooth number 20. This should form an arc that will allow you to place the shade guide under the edges of your teeth sliding it left or right to find the shade that matches your teeth. You want to be accurate with this step. This is exactly how TOP COSMETIC DENTIST do it. Click here to go to the tooth whitening Shade Guide.
2. Use normal room overhead light and slide the tooth whitening shade guide behind your teeth just under the edges. While looking into a mirror slide the shade guide left or right to  match your shade with one of the colors of teeth on the guide. WRITE THIS SHADE DOWN.  This is called your initial Shade.
4. Put your shade guide in a safe place because you will be measuring your progress once a week.  DON"T DO IT EVERY DAY.  You will change about a Shade a day so you won't see a hugh difference on a daily basis. However,  in a week you'll be excited that you have made such great progress. Write your progress shade down every week. You'll be able to determine how long it will take by counting the number of shades between your INITIAL SHADE AND TARGET SHADE if you use the Whitening  Gel as recommended.
3. Now this NEXT STEP is a very important step. You will want to  determine your TARGET SHADE. You need to be realistic about this step. To do this correctly  close your mouth and place the shade guide on your cheek. The PROPER SHADE HAS TO COMPLIMENT YOUR SKIN COLOR. Slide the tooth whitening shade guide toward the white end of the guide until you reach a shade that really looks good with your skin. You can be one or 2 shades either side of this shade but excessive white is NOT ATTRACTIVE. Be realistic. Now count the number of shades that you will have to changes to get to your TARGET SHADE. WRITE DOWN YOUR TARGET SHADE.
