What Is Tooth Whitening?

Tooth whitening, or bleaching as it is sometimes called, works very similarly to the way you might bleach your towels or other linens: by changing the color of your natural tooth enamel so that your teeth are brighter and whiter. Whitening treatments are easy and non-invasive, and the results can be quite literally dazzling. In many cases, there is no better way to boost the brilliance of your smile. In fact, having whiter teeth is our patients’ number one priority when it comes to cosmetic dental work!

There are two main ways to whiten teeth:

In our comfortable Empress Dental offices in Toronto or North York

In the comfort of your own home

REMINDER: Tooth whitening can only be done on natural tooth enamel, so if you have any old fillings, crowns, etc. that might need to be replaced, you should wait to do so until after your bleaching treatment. This way, all of your teeth will be the same color, and no one will know any differently. Also, if you need work done on the teeth you want to whiten, ask your Empress Dental dentist before starting a bleaching regimen.

Also, you should know that tooth whitening is not a permanent “fix.” You may require a touch-up every few years, and more often if you enjoy the following:

  • Smoking
  • Drinking coffee
  • Drinking tea
  • Drinking wine

Why Should I Whiten My Teeth?

Our patients choose to whiten their teeth for many reasons, including but not limited to:

  • Fluorosis (excessive fluoridation during tooth development – see our page about fluoride for more information)
  • Normal wear of outer tooth layer
  • Stained teeth due to medications such as tetracycline, etc.
  • Yellow- or brown-stained teeth
  • To look good for a wedding, graduation, or other special event
  • To improve self-confidence and feel more attractive

How Does the Whitening Process Work?

At Empress Dental, we use the Iveri Whitening System, which:

  • Is an in-office system
  • Consists of just 1-2 sessions that are 20 minutes in length
  • Typically combined with a cleaning appointment for the best results
  • We give you a one-size-fits-all, dual-arch tray to take home and use for touch ups and maintenance – no impressions or pour models required!
  • Uses red and blue LED technology to accelerate whitening and enhance gingival health without producing uncomfortable heat.
  • Comes in extra-strength (which contains 36% carbamide peroxide and 6% hydrogen peroxide) and regular strength (which contains only 36% carbamide peroxide) gel options
  • Contain potassium nitrate and xylitol to get rid of sensitivity and minimize dehydration.
