Question:
Do you brush your teeth before you put on crest white strips?
Answers:
Brush your teeth AFTER using the whitening strips.
When you brush your teeth, the toothpaste actually leaves a residue. This layer of residue protects your teeth from liquids and foods you eat that tend to wear at the enamel. It also protects your teeth from bacteria that grows in your mouth.
White strips are mostly baking soda, which burns away the top layer of you teeth, so if you brush before the strips you are only whitening (or burning rather) the layer of protection.
