Dry the surface of your teeth with a napkin or towel before applying the strips. This will help increase the whitening effect. You can also use a cheek retractor to spread your lips and control the flow of saliva during the whitening treatment. Less moisture in your mouth will give you a better result. Misuse can cause damage to your teeth, gums, and health.
