In 1923, the dentist John O. Butler decided to start a company which would produce toothbrushes and other dental hygien products. It was a good idea – Butler Company developed into a marvellously successful company. In 1988 it was bought up by the Japanese company Sunstar Inc, which placed a big part of the manufacturing in the US. Today, Sunstar is primarily known for their space brushes, dental floss and a wide range of special products adjusted for dental clinics.
