Teeth whitening (or bleaching) is a simple, non-invasive dental treatment used to change the color of natural tooth enamel and is an ideal way to enhance the beauty of your smile.

Because having whiter teeth has now become the number one aesthetic concern of most patients, there are a number of ways to whiten teeth.  The most popular method is using a home teeth whitening system that will whiten teeth dramatically.  Since teeth whitening only works on natural tooth enamel, it is important to evaluate replacement of any old fillings, crowns, etc.  Replacement of any restorations will be done after bleaching so they will match the newly bleached teeth.

Teeth whitening is not permanent.  A touch-up may be needed every several years, and more often if you smoke, drink coffee, tea, or wine.

Reasons for teeth whitening:

  • Fluorosis (excessive fluoridation during tooth development).
  • Normal wear of outer tooth layer.
  • Stained teeth due to medications (tetracycline, etc.).
  • Yellow, brown stained teeth.

What does teeth whitening involve?

This type of teeth whitening usually requires two visits.  At the first appointment, impressions (molds) will be made of your teeth to fabricate custom, clear, plastic, trays.

At your second appointment, you will try on the trays for proper fit, and adjustments will be made if necessary.  The trays are worn with special whitening solution either twice a day for 30 minutes or overnight for a couple of weeks depending on the degree of staining and desired level of whitening.  It is normal to experience tooth sensitivity during the time you are whitening your teeth, but it will subside shortly after you have stopped bleaching.

You will receive care instructions for your teeth and trays, and be encouraged to visit your dentist regularly to help maintain a beautiful, healthy, white smile.


The best way to whiten your teeth depends on your individual preferences, budget, and the condition of your teeth. The short answer: professional teeth whitening by a dentist. Why? It'll work better than store-bought or DIY methods.

Professional teeth whitening removes intrinsic (internal) and extrinsic (surface) stains, which means whiter, even, and longer-lasting results. It's also customized to you, including your sensitivity and desired shade of white.

Teeth whitening is safe for your teeth if you use a dentist-approved method and are a candidate. If you have tooth sensitivity, receding gums, dental work, or a history of oral disease, please check with your dentist before whitening your teeth. If you’re a candidate for teeth whitening, then one of the best ways to whiten teeth is dental teeth whitening at Northwest Dental.

Results from whitening treatment vary from person to person and on the type of stains. Teeth whitening generally works best on yellowish-brown stains compared to gray stains.

Optimal teeth whitening results are achieved when teeth are free from plaque and tartar buildup. Maintaining regular dental cleanings is crucial for your oral health and essential for maximizing the effectiveness of the whitening process. If it's time for your dental cleaning, consider scheduling it on the same day as your teeth whitening procedure, ensuring the cleaning is completed before the treatment.
