Teeth Whitening FAQ

1. What is teeth whitening?
Teeth whitening is a cosmetic dental procedure or at-home treatment that removes stains and discoloration from teeth, making them look brighter and whiter. It can be done professionally at a dentist’s office or using over-the-counter products like whitening strips, gels, or toothpaste.

2. How do Crest Whitening Strips work?
Crest Whitening Strips use a peroxide-based gel to break down stains on the surface of your teeth. The strips are applied to the teeth and left on for a specified amount of time (usually 30 minutes), during which the whitening agent penetrates the enamel to lift stains and discoloration.

3. How long do I need to use Crest Whitening Strips to see results?
Most users start seeing noticeable results after 3 to 5 days of consistent use. For optimal results, you typically need to use them for the full recommended duration, which is usually 10–14 days, depending on the specific product you are using. Products like Crest 3D White Professional Effects Whitestrips offer full whitening results in 20 days.

4. Are Crest Whitening Strips safe to use?
Yes, Crest Whitening Strips are safe when used as directed. They are a widely used and FDA-approved product. However, it is important not to exceed the recommended usage time to avoid potential tooth sensitivity or gum irritation.

5. Will Crest Whitening Strips cause tooth sensitivity?
Some users may experience mild tooth sensitivity while using whitening strips. This is temporary and should subside once you stop using the strips. If sensitivity occurs, try using the strips less frequently, or opt for a product designed for sensitive teeth. We advise customers to consult with their dentist before using any teeth whitening product.

6. Can Crest Whitening Strips work on crowns, veneers, or fillings?
No, Crest Whitening Strips will not whiten dental restorations like crowns, veneers, or fillings. They only work on natural tooth enamel, so if you have these dental work, they may not match the shade of your newly whitened teeth.

7. Can I use Crest Whitening Strips if I have braces?
It is not recommended to use Crest Whitening Strips while you have braces because they may not whiten the areas around the brackets evenly. If you want to whiten your teeth while wearing braces, consult your dentist for professional whitening options.

8. How should I care for my teeth after whitening?
After whitening your teeth, avoid foods and beverages that can stain your teeth, such as coffee, tea, red wine, or berries, for at least 24–48 hours. Maintain regular oral hygiene by brushing and flossing daily, and consider using a whitening toothpaste to help maintain your results.

9. How often can I use Crest Whitening Strips?
Crest recommends using whitening strips once a day for 10–14 days. After completing a whitening treatment, it’s best to wait a few months before using them again to avoid overuse and potential sensitivity.

10. Are there any side effects of using Crest Whitening Strips?
The most common side effects are tooth sensitivity and mild gum irritation. These side effects are generally temporary and should subside after you stop using the strips. If you experience persistent irritation or sensitivity, discontinue use and consult a dentist.

11. Can I use Crest Whitening Strips if I am pregnant or breastfeeding?
It’s always best to consult with your doctor or dentist before using any whitening products if you are pregnant or breastfeeding. While Crest Whitening Strips are generally considered safe, your healthcare provider can offer personalized advice.

12. Do Crest Whitening Strips provide permanent results?
The whitening effect from Crest Whitening Strips is not permanent. Over time, your teeth may gradually become stained again due to factors like diet, lifestyle, and aging. To maintain your bright smile, you may need occasional touch-up treatments.

13. Can I use Crest Whitening Strips with other whitening products?
If you’re using other whitening products, such as toothpaste or mouthwash, it’s safe to continue as long as you follow the instructions carefully. However, overuse of multiple whitening products at once could increase tooth sensitivity. Always consult your dentist if you’re unsure.
