Eating blueberries can reduce the risk of tooth decay. This fruit is good for oral health by preventing "bad bacteria" from sticking to the teeth and gums.
Researchers at the University of Queensland School of Dentistry in Australia examined the effects of cranberry, blueberry and strawberry extracts on oral bacteria. They treated 1-day-old S. mutans biofilms with high quality cranberry, blueberry and strawberry extracts, and a combination of three berry extracts.
The researchers evaluated the metabolic activity, acid production, biovolume, structural organization, and bacterial viability of the treated biofilm. The results showed that the biofilm treated with cranberry and blueberry extract showed the most significant reduction in metabolic activity, acid production and bacterial/exopolysaccharide (EPS) bio-volume, but its structure was not as controlled. The biofilm is so tight.
This study shows that nutrients in cranberries and blueberries are very effective in protecting teeth from the bacteria that cause tooth decay. Dark berries are a rich source of polyphenols that provide innovative bioactive molecules as a natural weapon against dental caries, plaque and gum disease.
Therefore, polyphenols are expected to develop new oral care products such as beverages, mouthwashes and toothpastes.
