There are advantages and disadvantages to everything, tea and coffee being no exception. They are refreshing and revitalising, but as year follows year you might notice the effect they can have on your teeth, more specifically the colour of your teeth. Your pearly whites take on a less becoming hue and you begin to wonder if they're a lost cause. Black tea, or 'normal' tea as I like to think of it, is actually a bigger culprit than coffee because it contains a higher level of tannic acid. Our teeth are covered in a thin layer of protein known as the pellicle and the tannins bond to it, hence the staining. There are various approaches you can take to reduce or slow down the effect:

  • The most radical would be to just drink water, but few of us have the desire, let alone the willpower, to lead such an ascetic life style.

  • You could try drinking white, green or herbal teas some of the time, as they have a lower capacity to stain teeth.

  • Waiting for your tea or coffee to cool down also reduces the effect.

  • Factoring in an extra tooth brushing session during the course of the day would be beneficial; chewing sugar free gum is a good alternative when out and about.

  • As the proteins in milk bind to tannins, it would follow that taking milk in your tea would be a wise move because there would be fewer tannins free to bind to your teeth.

  • If you're not fussed about looking a bit odd, then imbibing tea through a straw will reduce exposure to the tannins!

  • Of course there are a host of tooth whitening pastes on the supermarket shelves if your teeth are really beyond the pale.
