2080 (이공팔공) is a type of Korean toothpaste as well as a brand name for mouthwash and perhaps other dental products. Though the number 2080 is often thought of as meaning something along the lines of teeth guaranteed from the age of 20 to 80 the actual meaning is as follows:
20개워 건강한 치아를 80세까지 - Twenty(!) healthy teeth until the age of eighty
