7. Don’t spend money on Over-the-Counter Whitening Trays

We don’t recommend the over-the-counter whitening kits available in convenience stores and online. Unlike custom-made whitening trays from your dentist, these have low concentrations of hydrogen peroxide because their non-custom-fitted structure means the gel will encounter your gums.

8. Use Custom-Fitted Teeth Whitening Trays

Available at your dentist, custom-fitted teeth whitening trays have higher concentrations of hydrogen peroxide than what is found in whitening toothpastes and non-custom (over-the-counter) trays. They also fit better than non-custom trays, making them more effective in whitening your teeth while reducing the amount of peroxide that touches your gums. Custom-fitted trays require two trips to lớn your dentist. The first is so your dentist can perform a 3 chiều scan of your teeth khổng lồ create your trays; the second is lớn ensure your trays fit correctly.

9. Opt for In-Office Teeth Whitening

We believe that in-office whitening is the best teeth whitening method. Available at your dentist’s office, in-office whitening is comparable lớn custom trays — including in cost — but offers a faster way to brighten your teeth. And, unlike custom trays which require two dental appointments, in-office whitening requires only one. In little more than 90 minutes, your dentist will apply a hydrogen peroxide gel to your teeth, followed by a special lamp that aids in the whitening process. Another benefit of in-office whitening is that the limited gel application means you’re less likely khổng lồ experience tooth or gum sensitivity.

 10. Visit Your Dentist for a Cleaning

Although daily brushing and flossing will help whiten your teeth, don’t forget to lớn visit your dentist for your regular cleanings. A dental cleaning is more thorough than at-home brushing & it removes plaque, which ordinary brushing can’t do. Most people should see a dentist every 6 months, but some people should go more often. If you’re not sure how often you should get your teeth cleaned, we have a blog post on how often lớn see the dentist that answers a lot of common questions.

11. Final Teeth Whitening Tip: Don’t Use Hydrogen Peroxide at Home

If you bởi manage lớn find hydrogen peroxide with a higher concentration, be aware it can cause serious tooth damage. Therefore, we do not recommend using hydrogen peroxide at home to whiten teeth.
