should i brush my teeth after using whitening strips

It's generally recommended to avoid brushing your teeth immediately after using whitening strips. Brushing right away can cause irritation to your gums, especially if they are already sensitive from the whitening agents. It can also potentially spread any remaining peroxide on your gums, further increasing sensitivity.\n\nInstead, rinse your mouth thoroughly with water to remove any residual gel. Wait at least 30 minutes to an hour before brushing your teeth gently with a soft-bristled brush. If you experience persistent sensitivity, consult your dentist.
