Generally, bleaching is successful in at least 90% of patients, though it may not be an option for everyone.
Consider tooth bleaching if your teeth are darkened from age, coffee, tea, red wine or smoking. Teeth darkened with shades of yellow, brown or orange respond better to lightening. Gray stains caused by fluorosis, smoking or tetracycline can be lightened, but the results are not as dramatic. If you have sensitive teeth, gum disease, or teeth with worn enamel, your dentist may discourage bleaching.
How long does it last?
Bleaching should last 1 to 5 years, depending on your personal habits such as smoking and drinking coffee and tea.
At some point you may want a touch-up.
How does it work?
The active ingredient in most of the whitening agents is 10% carbamide peroxide.
When water comes in contact with it, the release of hydrogen peroxide lightens the teeth.
Is it safe? Are there any side effects?
Studies have proven bleaching to be safe and effective.
Some patients may experience slight gum irritation or tooth sensitivity, which ends when the treatment does.
What are the realistic expectations?
Typically, there is a two-shade improvement as seen on a dentist's shade guide. The success rate depends on the type of stain involved and your compliance. Bleaching can only provide a shift in color from gray to a lighter shade of gray. Bleaching does not lighten artificial materials such as resins, silicates or porcelains.

Eating healthy
reverses metabolic syndrome
Dr. Tasnime Akbaraly of University College London and her colleagues were interested if healthy eating could actually turn-the-tide and reverse metabolic syndrome, which is having 3 or more of the following risk factors: excess abdominal fat; high triglycerides, hypertension, low levels of HDL the “good” cholesterol, or type 2 diabetes. Having metabolic syndrome doubles a persons’ risk of heart disease and greatly increases the odds of developing type 2 diabetes.
The researchers studied 339 British civil servants with metabolic syndrome, and how closely the adhered to the Alternative Healthy Eating Index (AHEI) to see if it could help reverse metabolic syndrome. The AHEI is a set of published nutritional guidelines by the Harvard School of Public Health in 2002 that emphasizes whole grains, fruits, vegetables and decreased red meat consumption.
Five years into the study, nearly 50% no longer had metabolic syndrome. People who followed the AHEI guidelines the closest were nearly twice as likely to have reversed their metabolic syndrome. The results of the study were published in Diabetes Care, online July 29, 2010.
Dr. Alice Lichtenstein, an expert on diet and heart health from Tufts University in Boston who was not involved in the study said, "It's not about focusing on individual components of the diet, it's really the whole package, and that becomes important because it means that if one of the components of a healthy diet is to eat more fruits and vegetables, just buying a pill saying that there's a concentrated extract of fruits and vegetables is probably not what's going to help you."
