How does the peroxide gel work on your teeth?
Whitening strips contain a peroxide gel held against the enamel by a flexible carrier. The gel can irritate gingiva if it overlaps the gumline and can increase sensitivity in exposed dentin.
What steps should you follow when applying the strips?
Brush gently, dry the teeth if directed, align the strip below the gumline, fold the excess behind the teeth, and remove it at the stated time. Do not cut or share a strip.
Which symptoms mean you should stop and see a dentist?
Stop the course and contact a dentist if pain is severe, gum tissue turns white and sore, or symptoms persist after removal.
What should you ask about strength, restorations and sensitivity?
Ask which product strength is appropriate, whether fillings or crowns will change shade, and how to manage sensitivity.
