Things You'll Need:
- Whitening strips
- Timer
- Toothpaste for sensitive teeth (optional)
-
Step 1
Open the packet for the upper teeth and remove the whitening strip. Remove the protective shield from the strip's gel side and place the edge of gel side against your upper teeth. Adjust it to avoid getting the gel on your gums and smooth the strip against your teeth. Fold the excess edge behind your teeth.
-
Step 2
Open the packet for the lower teeth, remove the protective shield and place the strip on your lower teeth. Adjust and smooth the strip over the edge and behind your teeth.
-
Step 3
Set the timer for the amount of time mentioned in the instructions on the box. The average amount is 15 minutes in the morning and 15 minutes in the evening. If you have the dissolving type of whitening strips, there is no need to set a timer.
-
Step 4
Remove the strips when the timer goes off. Spit out--don't swallow--the remaining gel. Brush your teeth and rinse thoroughly to remove the remaining hydrogen peroxide.
-
Step 5
Repeat the use of the whitening strips according to the package's instructions. Each box will contain the amount needed for a complete treatment; this will typically be between 7 to 14 days. The strips with higher concentrations of hydrogen peroxide will require fewer days to use. If you have achieved the level of whiteness that you want, you can stop sooner and save the remaining strips for later use.
