Teeth whitening

Teeth whitening

Having a beautiful smile may be even easier than you think. Many people achieve the look they’ve been dreaming of with our simple “whitening” procedure.

What can cause tooth discoloration?

There are many causes including aging and consumption of staining substances such as coffee, tea, or tobacco. During tooth formation consumption of tetracycline, certain antibiotics or excessive fluoride may also cause tooth discoloration.

Dental whitening can be used to correct tooth discoloration. In cases of extreme discoloration, crowns or veneers may be the only choice, but because of the low cost of whitening treatments, teeth whitening is nearly always worth a try.

Is teeth whitening safe? Research and clinical studies indicate that whitening teeth under the supervision of a dentist is safe. In fact, many dentists consider whitening the safest cosmetic dental procedure available. 

Whitening Options

Dr. Lee, Dr. Tu & Dr. Chung will help assess your teeth to decide which treatment method is best for you. We offer the following teeth whitening procedures:

Zoom! Professional In-office Whitening

Zoom! is a great option for people who want immediate results. It uses proprietary light-activated technology to whiten your teeth significantly in just over an hour. The Zoom! light-activated whitening gel’s active ingredient is Hydrogen Peroxide. As Hydrogen Peroxide is broken down, oxygen enters the enamel and dentin, bleaching any colored substance while keeping the structure of the tooth unchanged.

Custom bleaching trays and Take-home gels

An impression is taken to make a custom “retainer” to hold the bleach against the teeth. We provide you with bleaching gel to use each night for about 3-4 hours for a week or two. With only a few hours of wear per day, our bleaching agent bubbles stains right out of your enamel. When your teeth reach the desired brightness, only occasional treatment is needed to maintain your new smile. This may be a suitable option for people who prefer the convenience of whitening at home or have issues with tooth sensitivity.

Are there any side effects?

Some people experience temporary increased tooth sensitivity to cold during treatment. These symptoms disappear within 1-3 days after interruption or completion of the treatment. We may recommend pre and/or post-procedural use of a desensitizing toothpaste if your teeth are more prone to cold sensitivity.

Key Benefits of Teeth Whitening

  • Corrects brown, yellow and spotted tooth staining

Do the results last a long time?

By following some simple post whitening care instructions, your teeth will always be lighter than they were before. We recommend flossing, brushing twice daily, and touch-ups with the take-home bleaching gel. These are professional formula products designed specifically to keep your teeth their brightest. They are available through our office.
