Generally speaking, when writing out numbers in words between 21 and 99 in English, hyphens are used between the tens digit and units digit. This contrasts with a language such as Italian, where numbers between 21 and 99 are written as single words, without hyphens, for example, the word for the number 32 is trentadue.
