MILK IN YOUR TEA CAN PREVENT TOOTH STAINS

In dental circles it is well known that certain drinks have a propensity to discolour teeth. Red wine, black coffee, tea and cola drinks among them.

However research in Alberta, Canada has shown that adding a splash of milk to your tea will stop it from staining your teeth.

The staining is caused by tannin in the tea, which is water soluble but which is bound by a protein called 'casein' which is found in milk. This stops it attaching itself to the tooth enamel.

The experiment was carried out on extracted teeth in a lab by placing some in tea and other teeth in a mixture of tea and milk at 37⁰ for 24 hours.

Dr Ava Chow, assistant professor at the university dental department in Alberta, said that the addition of milk prior to consumption of tea had a greater whitening effect than preventative use of a whitening toothpaste.
