Should I brush my teeth before using?Updated a month ago

Yes, it's generally a good idea to brush your teeth before using whitening strips. Brushing helps remove plaque, food particles, and any surface debris, which can allow the whitening strips to adhere better to your teeth and work more effectively. Just make sure you brush gently, as you don't want to irritate your gums, and give your teeth a little time to dry before applying the strips. That way, the whitening gel can get to work more efficiently!
