Professional Teeth Whitening

If you find yourself trying to smile without showingteeth whitening your teeth, or move your lips as little as possible while you speak because your teeth make you feel self-conscious, that is terribly sad. Everyone should be able to enjoy smiling. But if your teeth are yellowed or dingy, you might be reluctant to smile. Fortunately, there are treatments available that can remove stains and whiten your teeth by several shades.


Tooth Whitening Treatments from Your Dentist

You have undoubtedly seen tooth whitening treatments in drug stores and you may even have tried one. Chances are the results were nowhere near as good as you expected. It is a common misconception that these products can deliver the same results as your dentist. This is because commercially available treatments lack the powerful ingredients that allow your dentist to whiten your teeth by several shades, safely and effectively.


KoR™ Deep Bleaching

The KoR™ Deep Bleaching system is the one most recommended by Dr. William Schlesinger. It works by means of a powerful bleaching gel that penetrates deep into your teeth, destroying stain molecules and restoring the ability of your teeth to absorb oxygen. Even older teeth can be restored to their youthful condition. Other bleaching methods may last a long time, but they cannot be considered permanent. KoR, however, when followed up with home treatments, is permanent.

teeth whiteningThe KoR system is also customized for you. With other treatments, the dentist will usually have a number of different-sized bleaching trays available and will choose the one that best fits your mouth. With the KoR system, Dr. Schlesinger will actually take impressions of your teeth so that you will have your own, custom-fitted trays. The bleach is then sealed within the tray so that nothing will leak and possibly irritate your gums.

You will begin with an in-office treatment and then you will be given gel-filled trays to take home and wear while you sleep. Because the trays are so form-fitting and so thin, you may not even notice that they are in your mouth. You will use the at-home trays for two weeks and then return to Dr. Schlesinger’s office for a final treatment. The in-office treatments take anywhere from an hour to an hour and a half.


Zoom!® Teeth Whitening

The Zoom!® teeth whitening formula also works byteeth whitening means of gel-filled trays. They are not custom-fitted, but it is generally not difficult to find trays that will feel comfortable in your mouth. The Zoom! whitening gel is placed in the tray, and then the tray is placed in your mouth. You can relax while the whitening gel does its work. When the in-office treatment is finished, you will be given trays to take home so that you can continue whitening your teeth at your convenience.

You will need to come back periodically for additional professional treatments so that your teeth will continue to look good. As long as you continue your whitening treatments, you can be assured of a brilliant smile.



Opalescence® whitening treatments are another highly teeth whiteningeffective way of whitening your teeth. The treatment consists of take-home kits containing trays and a 20% peroxide gel. If you have sensitive teeth, this could be the ideal treatment for you. As an additional benefit, Opalescence prevents cavities and improves the hardness of your tooth enamel.
