Is it ok to use whitening strips
Whitening strips may lighten natural enamel by placing a peroxide gel against the tooth surface, but their use depends on your gums, enamel, fillings, and
The short answer
Whitening strips are flexible pieces coated with a peroxide-based gel. The gel can pass into enamel and break down some stain molecules, but it does not whiten crowns, veneers, fillings, or other dental restorations.
How should you check your mouth before using whitening strips?
Check that your teeth and gums are healthy, follow the product directions exactly, and stop if you develop marked burning, ulceration, or lasting sensitivity. Do not place strips on broken gum tissue or use them to treat pain or a dark tooth without an examination.
When should you see a dentist before using whitening strips?
See a dentist before whitening if you have cavities, gum disease, enamel defects, exposed roots, severe sensitivity, pregnancy-related questions, or visible restorations in the smile zone. Seek prompt care for swelling or spontaneous tooth pain.
What should you ask about whitening strips and restorations?
Ask whether the discoloration is surface stain or a change inside the tooth, whether restorations will match afterward, and which concentration and schedule fit your mouth.
Frequently asked questions
Do strips whiten fillings?
No. Whitening changes natural tooth structure, so a filling or crown may remain a different shade.
Why do my teeth hurt after strips?
Peroxide can temporarily irritate dentin or the pulp through enamel, but strong or lasting pain should be assessed.
