RED wine could prevent tooth decay, according to a study by Spanish scientists.

Scientists dipped samples of bacteria into various liquids, including red wine alone, red wine without alcohol, red wine mixed with grape seed extract, water and 12% ethanol.

Project leader Dr Victoria Moreno-Arribas said: “Red wine with or without alcohol and wine with grape seed extract were the most effective at getting rid of the bacteria.”

It is hoped that the findings could lead to the development of natural products to fight dental diseases.
