Teeth whitening results can last for several months or even a few years, depending on your habits. So, if you’re wondering “how long does teeth whitening last” or “how to maintain teeth whitening,” the answers are variable.

To maintain your results longer, we recommend:

  • Avoiding tooth-staining foods, such as coffee, tea, red wine, and bright sauces
  • Brushing and flossing at least twice daily.
  • Seeing your dentist twice a year for dental checkups and teeth cleanings

About Professional Teeth Whitening in Bellevue

We offer three teeth whitening options to meet your needs:

  • In-Office Teeth Whitening
  • Professional Teeth Whitening Strips
  • Custom Bleaching Trays

In-office teeth whitening is typically the fastest way to brighten your smile. Take-home kits and whitening strips allow you to whiten on your own time and better control your results.

No matter which at-home whitening option you choose, be sure to follow your dentist's instructions, and always call us if you have questions.

Why You Should Leave Teeth Whitening to a Dentist

With all the whitening kits available in stores and online, it’s tempting to whiten your teeth on your own.

However, these products are not prescription-strength, which can lead to disappointing results. Additionally, the ingredients may not be suitable for your dental health. Whitening on your own can also mean lingering tooth sensitivity and enamel damage.

When you whiten your teeth with the dentist, we ensure your oral health is up to the challenge. We also clean your teeth first to enhance your whitening results, especially if you haven’t been in to see us in a while.

Whitening with the dentist is simply safer and more effective.
