Is saying "Es necesario que ustedes cepillen sus dientes" slightly incorrect? I seem to recall that the last part means "brush their teeth", but implying that their teeth aren't part of them, like fake teeth.
Is this true?

Also, is there phrasing/a word that means 'sans'?

Es necesario que SE cepillen los dientes

it's not gramatically incorrect, but it's certainly not used in oral or written spanish. while in english we say "brush my/your/his teeth", in spanish we use the definite article, "cepillarse LOS dientes".
