Water is a commodity whose limitations are becoming an increasingly widespread reality. Therefore, Tooth Clock optimizes water consumption in daily brushing and thus offers a small but concrete step on the individual contribution to the good of society in this field. The use of the Tooth Clock is based on the modification of the hourglass and is used in three phases. First, the tube is filled with water with a hole that causes the water to drain, so we put it in a glass. This is followed by brushing your teeth, which measures a 3-minute outflow of water. Then, after 3 minutes, the glass is full of water with which you rinse your mouth and thus end the use.
