14 DAY TRIAL // People who drink at least three cups of black tea per day are less likely to suffer from tooth decay, researchers writing in the British Nutrition Foundation’s Nutrition Bulletin argue.
Interestingly enough, this beverage continues to fight back tooth decay regardless of whether or not the people who consume it add some sugar in it.
Experiments have shown that several chemical compounds found in black tea are highly effective in terms of keeping two types of bacteria, i.e. Streptococcus mutans and Lactobacillus, at bay.
Both these bacteria have previously been documented to foster not just tooth decay, but also gum disease, Daily Mail tells us.
Black tea consumption keeps them from setting up camp and starting to breed, and reduces inflammation inside a person's mouth.
As Dr. Tim Bond puts it, “This benefit is thought to be due to a reduction in inflammation in the oral cavity and prevention of the adhesion and growth of bacteria linked to periodontal disease.”
According to Dr. Carrie Ruxton, green tea also helps fight back tooth decay.
It isn't as effective as black tea, yet it does yield one other benefit: it prevents bad breath by neutralizing several sulphur compounds that have been linked to this condition.
