Many widely consumed polyphenol-rich foods or beverages including tea, coffee or wine, have been shown to benefit oral health, with anti-gingivitis and anti-caries properties. Objective: To investigate the effect of commercially available teas and bottled beverages containing plant-derived polyphenols on in vitro growth and biofilm formation of supragingival plaque bacteria isolated from children. Methods: Supragingival plaque bacteria obtained from tooth surfaces of children were treated with nine commercially available teas and beverages. The effects of test teas, juices or beverages on in vitro growth and biofilm formation of plaque bacteria were examined. Results: All teas tested inhibited the growth and biofilm formation of the supragingival plaque bacteria. Bottled beverages varied in the inhibition of growth and biofilm formation. Biofilm formed in the presence of plant-derived polyphenols were loosely adherent and easily dislodged from surfaces, indicating weakened biofilm attachment. Conclusions: Commercially available teas and beverages containing plant-derived polyphenols may benefit children’s oral health by suppressing growth and biofilm formation of the supragingival plaque bacteria. The concept of oral diseases prevention using natural foods or beverages may be a novel and practical approach to promote oral health in children.
