Drinking black tea can contribute to good oral health, an expert has noted.
The Tea Advisory Panel's Dr Carrie Ruxton explained antibacterial properties have been observed in flavonoids contained in the drink.
These can kill bacteria in the mouth and therefore help to prevent tooth decay, while enamel can be protected by the fluoride present in tea.
Dr Ruxton was commenting after research commissioned by the Tea Advisory Panel and published in Network Health Dieticians suggested black tea has just as many health benefits as green tea - despite the latter being perceived as a healthier alternative.
Both varieties come from the same plant and contain similar compounds and Dr Ruxton explained the difference lies in how they are processed.
In addition to the positive effects on oral health, the expert observed drinking around four cups of black tea every day can help to reduce the risk of heart disease.
