New Study Finds No Conclusive Evidence Linking Juice to Dental Cavities and Tooth Decay

A new dental literature review published in Frontiers in Public Health finds there is no conclusive evidence that drinking juice has a negative impact on dental health. The study reviewed existing data about 100% juice and corresponding dental health outcomes in children, adolescents, and adults.

The JPA-sponsored study reviewed eight publications representing five independent prospective cohort studies in children and adolescents, and nine Randomized Clinical Controls (RCT) in adults. The studies conducted on children and adolescents found no association between 100% fruit juice and tooth decay or dental cavities. These studies reflected normal intakes of juices and dental hygiene practices. While the results of the adult study suggested a potential association, this data was primarily conducted using intra-oral devices and conditions that are not reflective of typical juice consumption.

More research is necessary to reach definitive conclusions on this subject. Larger, well-designed intervention studies are especially needed, as these approaches involve consensus study techniques with a more accurate reflection of dynamics of healthy teeth  in both adults and children. These types of studies are also essential for enacting policies and making clinical recommendations on the intake of 100% fruit juice.

While the current research says there is no need to be concerned about your dental health when drinking juice under normal circumstances, proper dental hygiene is the key to preventing cavities.
