Big name in dental products

ORALB

This brand’s toothbrushes often feature a distinctive round head and are owned by the same company that makes Gillette razors.

This clue hints at a well-known brand in dental care, specifically toothbrushes and toothpaste. "Big name" suggests a major company, and "Oral-B" fits perfectly as a household brand in oral hygiene. The answer plays on the word "oral," which directly relates to the mouth, making it a straightforward but clever reference.
