should you brush your teeth before whitening strips

Yes, it is generally recommended to brush your teeth before applying whitening strips. Brushing helps remove plaque and food debris, which can create a barrier between the whitening agent and your tooth enamel. A clean tooth surface allows for better contact and absorption of the whitening gel, leading to more effective results.\n\nWhile brushing, be sure to do so gently and at least 30 minutes prior to strip application. Brushing too vigorously or immediately before can irritate your gums, making them more sensitive to the whitening agents. If you have concerns about sensitivity, consult your dentist before starting any at-home whitening regimen.
