Cranberry Juice Fights Tooth Plaque: New Study
11 Nov
Summary
- Unsweetened cranberry juice slowed plaque bacteria regrowth by 44%.
- Plaque bacteria produced fewer enamel-eroding acids with pure juice.
- Study involved 22 participants, larger trials needed for confirmation.
New research from the University of Illinois Chicago indicates that unsweetened 100% cranberry juice may offer benefits for oral health. Published in Scientific Reports, the study found that pure cranberry juice slowed the regrowth of plaque bacteria and reduced their acid production, which can erode tooth enamel.
Laboratory tests on plaque samples from 22 participants showed a notable decrease in bacterial regrowth. Adults experienced approximately 44% less regrowth, while children saw about 33% less regrowth after rinsing with pure cranberry juice. The juice cocktail and water had no significant effect.
While promising, the study's lead, Christine Wu, emphasizes that these findings are based on a small sample size. Further research is necessary to confirm these potential oral health advantages. It's important to remember that cranberry juice is not a replacement for regular brushing and flossing.
