I guess that "szczoteczki" looks plural to you.
The verb "używać" (to use) takes a direct object in the Genitive case. "szczoteczki" here is Genitive singular.
Genitive singular of feminine nouns almost always is identical to their Nominative/Accusative plural forms. Yes, "szczoteczki" is also plural, just not in this sentence.
