A look at the staining properties of foods on our teeth.
Few of us these days perhaps, eat a diet entirely made up of fresh food, relying at least occasionally on takeaway food, supermarket ready meals or even sandwiches and other ready made snacks.
Although many of these are becoming more healthy due to general awareness by the public, many do still contain food colourings which are designed to make the food more appealing to our eyes, and therefore more likely to be purchased.
Stained Teeth
Whilst tobacco is probably by far still the biggest culprit when it comes to heavily stained teeth, food colourings too may also cause discolouration, especially if used over a period of time. Even some very natural colourings such as the spice, turmeric, can cause discolouration when eaten frequently.
The effects of these food colourings are highly unlikely to be noticed immediately, but the effects can build up over a period of time, the length of which may depend upon how regularly we eat these.
