This 8ft tower of teeth is foul, and the summit of 15 years work by Yu Qian, a Chinese dentist who is trying to raise awareness about dental hygiene by word of mouth. His piece of art is made from 28,000 human teeth. So far he has treated 100,000 patients, and ‘harvested’ 28,000 diseased teeth. The tower includes five different types of diseased teeth and has been made using various unspecified adhesive materials.
