Contact allergy to toothpaste flavors.

Abstract

Toothpaste flavors are fragrance mixtures. Oil of peppermint and spearmint, carvone and anethole are ingredients with a low sensitizing potential, but they are used in almost every brand of toothpaste and caused seven cases of contact allergy in a 6-year period at Gentofte Hospital. Toothpaste reactions are rare due to several reasons; local factors in the mouth, the low sensitizing potential of the flavors generally used, and the lack of recognition. It is emphasized that the toothpaste battery for patch testing has to be relevant and changed according to the consumers' and manufacturers' taste and fashion.
