Teeth whitening is the process of cosmetically altering the shade of your teeth to make them appear whiter and more attractive.
It’s strictly a cosmetic treatment and won’t affect or improve the functioning of your teeth in any way. The treatment can make a significant difference in your overall appearance and helps you feel more confident in the way your smile looks.
At The Smile Agency Orthodontics & Smile Design, Dr. Guinn helps you choose a professional teeth whitening treatment that fits your schedule, no matter how busy you are. During the planning stage, she can predict just how much whiter your teeth will get once your treatment is complete.

Unlike the whitening products you can find at the drugstore, professional teeth whitening products contain high concentrations of strong whiteners like hydrogen peroxide or carbamide peroxide. These substances break up the pigment in your stains, making your teeth appear whiter.

At The Smile Agency, get the smile you always wanted!

Dr. Guinn provides a few teeth whitening treatment options and helps you select the one that is best for you. Both options use professional solutions, so there is virtually no difference in the results that each can achieve. You can choose:

Office Whitening

Office whitening is the faster option. During the procedure, Dr. Guinn applies a protective gel to your gums and a bleaching gel to your teeth. She shines a special light on the gel to activate it, causing your teeth to whiten significantly in just one visit.

Home Whitening

Dr. Guinn gives you custom-fit trays to wear at home. She tells you how much product to use and how long to wear the trays depending on the concentration of the product. You may need to use the trays for several days or weeks until you reach your whitening goal.

Teeth whitening is highly effective for many stains and discolorations, but there are stains that it can’t treat. One way to tell whether you can treat your teeth is to examine their color. Yellow or brown stains usually respond well to teeth whitening and are due to food, drinks, and tobacco.
If you have staining that appears gray, it may not lift with teeth whitening treatments. Gray tones usually come from traumatic injuries, medications, and dental treatments. For gray teeth, Dr. Guinn might recommend a crown or veneer instead.
If you’ve tried to whiten your teeth at home with over-the-counter products without success, call The Smile Agency Orthodontics & Smile Design or book a consultation to try professional whitening today.
