Four photos of a wisdom tooth showing how it looks before and after being soaked in a cola for a day, a week and a month

Four photos showing a human wisdom tooth being soaked in cola for a month. Photos taken at different times. Top left before put in cola. Top right after about 24 hours. Bottom left after one week and bottom right after one month. The phosphoric acid (E338) in cola drinks erodes the enamel. A lot of the enamel is gone on the last picture.
