'Couto' toothpaste was developed in 1930s by the Alberto Ferreira Couto. This medicinal toothpaste played an important role in changing oral hygiene habits in Portugal. The toothpaste was registered in Oporto in 1932 and was an immediate success; 'couto paste' is still used in Portugal as a synonym for toothpaste. The toothpaste should be allowed to work in the mouth for a few minutes after application to maximise the antiseptic effect.
