Do i use whitening strips before or after brushing
Whitening strips are placed on clean, dry teeth according to their instructions, and brushing immediately beforehand may irritate gums.
The short answer
A strip holds peroxide gel against enamel for a set time. Brushing removes plaque but can temporarily irritate the gingival margin if the strip overlaps it.
How can brushing and gum irritation affect strip application?
Clean the teeth earlier, allow irritated gums to settle, and place the strip on tooth surfaces rather than gums. Remove it at the instructed time and do not exceed the schedule.
When should you stop using whitening strips and seek advice?
Stop for sharp or persistent sensitivity, painful white gum patches, decay, cracks, or poor strip fit.
What should you ask before using whitening strips?
Ask whether your teeth and gums are ready, how to separate brushing from application, and whether restorations will remain a different shade.
