Without being too much of a kill- joy, research has also shown that the modern habit of drinking coffee and tea – on average four cups per day - with one in three British adults adding sometimes two to three teaspoonfuls of sugar to their drink, increases seriously , the frequency of acid attack on the teeth.

Each teaspoonful contains 4g of sugar whih means that four cups of tea or coffee per day, with just one teaspoonful of sugar, could in itself make up half of a person’s daily recommended sugar intake.
