Is teeth whitening dangerous?
Whether it's over the counter or under the lights, teeth whitening has become a common cosmetic procedure.
"Over the years a lot of coffee and tea and your teeth do darken down. So I wanted to see what it would be like if they made them lighter,” said Jane Graf, patient.
Some whitening products have been linked to tooth erosion.
Doctor Yanfang Ren of the Eastman Institute for Oral Health decided to compare the effects of a common whitener with orange juice.
"We want to measure the depths of erosion,” said Ren.
Ren found when put in contact with teeth in the same manor, the acid in the orange juice was much more dangerous to tooth enamel than the whitener.

Ren says if used properly the whitener is safe and since the study used orange juice on the surface of a tooth for 20 minutes a day, Ren says drinking juice or soft drinks normally isn't that risky either.
