How white is enough? Well, no one really knows given the rush in recent years to have a white smile. What we do know, is that there are additional benefits beyond bleaching your teeth. So while attempting to achieve the right smile with a bright smile, whitening your teeth with 10% carbamide peroxide may actually help prevent cavities (dental caries). The bacteria that causes cavities flourish when the pH of your mouth is slightly acidic, which is a bi-product when you eat or drink. There is evidence according to Dr. Van Hayword of GRU that a 10% carbamide peroxide bleaching gel in a custom tray can help elevate the pH, which helps fight decay. There is also some evidence that the same regimen can help keep plaque from forming on the teeth, which may help prevent gum disease.
Deciding how white is enough is a personal decision where weighing the costs and benefits of any cosmetic transformation probably should involve the input of your dental provider. I encourage you to contact your dentist if you have any questions or concerns please feel free to contact us.

 Carbamide peroxide (10% and 15%) has been classified by the United States Food and Drug Association as Category 1, which means there is sufficient data to demonstrate that these agents are safe and effective for use in the oral cavity as oral antiseptic agents (Haywood, 1993; Dental Product Spotlight, 2001).
