Orange Juice Is More Detrimental Than Teeth Whitening Products

Published:August 4th, 2010

Researchers at the Eastman Institute for Oral Health have revealed that orange juice has negative effects on our teeth. They also assessed the effects of teeth whitening products and have concluded that orange juice can cause more damage than teeth whitening products.

The effects of 6% hydrogen peroxide were insignificant compared to acidic fruit juices. Orange juice decreases hardness but increases roughness of tooth enamel. Extensive surface details could be observed due to a new focus variation vertical scanning microscope.

The acid is so strong that the tooth is literally washed away. The orange juice decreased enamel hardness by 84%. However, no significant change in hardness or surface enamel was found from teeth whitening products.

When tooth enamel is weakened or eroded, the wear of the teeth can speed up, so risk of tooth decay becomes greater. Juice and sodas have high acid content and it has long been known that they can affect enamel hardness. However, this was the first study to compare the effect of orange juice and of teeth whitening products.
