What Are Teeth Whitener Strips
Teeth whitener strips are thin, flexible plastic patches coated with a peroxide-based gel. You place them on the front surfaces of your teeth for a set time, usually 10 to 30 minutes. The gel temporarily penetrates the enamel to break down surface and deeper stains, according to the American Dental Association.
How Effective Are Whitening Strips
Whitening strips can lighten teeth by several shades over a typical two-week course. Results vary based on stain type, concentration of whitening agent, and how consistently you use them. They work best on yellowish surface stains but are less effective on gray tones caused by medication or trauma.
How to Use Whitening Strips Safely
Follow the package instructions and do not exceed the recommended daily wear time. Common side effects include temporary tooth sensitivity and gum irritation. Avoid using strips with cracked or damaged enamel, and consult a dentist if you have restorations, cavities, or gum disease.
