Our Most Asked Questions.

1. How do Crest Whitening Strips work?

Crest Whitening Strips use a thin layer of peroxide gel on flexible plastic strips. The peroxide penetrates the enamel to remove surface and set-in stains, whitening teeth over time.

2. How long should I wear Crest Whitening Strips?

It depends on the product. Most strips are worn for 30 minutes once daily. Some intensive products (like Crest 3D Whitestrips Professional Effects) may require shorter or longer application times. Always follow the instructions on the box.

3. How long does it take to see results?

Many users see visible results in 3 days, with full results after 10–20 days, depending on the product.

4. Are Crest Whitening Strips safe for my teeth and gums?

Yes, when used as directed. Crest Whitestrips are enamel-safe and approved by the American Dental Association (ADA). However, some users may experience temporary sensitivity or gum irritation.

5. Can I brush my teeth before or after using the strips?

Yes. It’s best to brush gently before applying, but avoid toothpaste with strong abrasives right before treatment. After removing the strips, you can brush again to remove any gel residue.

6. Can I use them if I have dental work (crowns, veneers, fillings)?

Whitestrips will not whiten crowns, veneers, or fillings—only natural tooth enamel. This could result in uneven whitening if you have visible dental work.

7. How does delivery work?

We offer same-day delivery across the UK for all orders placed before 3 PM (Monday–Saturday). Orders placed after 3 PM will be dispatched the next working day.

8. Do you offer international shipping?

Currently, we only ship within the UK.

9. What happens if I miss a day?

It’s okay. Just continue with the next treatment. Do not use multiple treatments in one day to make up for a missed one.

10. Can I track my order?

Yes, once your order is dispatched, you will receive a tracking link via email or SMS.

11. Who can I contact for support?

You can reach us via live chat on our website, available Monday to Saturday, 9 AM to 6 PM. Please only use the live chat as this is our main point of call with our customers.

12. Can I eat or drink after using the strips?

Yes, but it’s best to wait 30 minutes after removing the strips. Avoid staining foods and drinks (like coffee, wine, or berries) for the best results.

13. Do Crest Whitening Strips expire?

Yes, they typically have a shelf life of about 12–18 months. Expired strips may be less effective.

14. Can I use Crest Whitening Strips while pregnant or breastfeeding?

Consult your dentist or doctor first. While there’s no clear evidence of harm, safety during pregnancy or breastfeeding has not been fully established.
