Frequent sugar intake in coffee is a common cause of dental caries (decay). Aspartame is an artificial sweetener and does not cause caries. I would like to know whether using aspartame instead of sugar affects how coffee drinkers perceive the taste. To take part in this trial you need to be drinking coffee with sugar. Please DO NOT add sugar to your coffee if you don't already just to take part in this trial - that would potentially damage your teeth!

Please buy a packet of aspartame tablets or powder, or grab a few from a cafe or McDonalds. Use the aspartame instead of your usual sugar for 3 cups of coffee. After the 4th cup please come back and answer the question.
Please continue using sugar as normal in your coffee. Drink your next 3 cups as normal but after the 4th please come back and answer the question.
