Which term refers to something related to the mouth?

The term "oral" specifically pertains to the mouth and is often used in medical and health contexts to describe anything associated with the oral cavity, which includes the lips, tongue, cheeks, and the structures within the mouth. It encompasses various functions and practices, such as oral hygiene, oral surgery, and oral health, highlighting its direct connection to the mouth itself.

In contrast, the term "bucal" is another word for oral but is less commonly used in many contexts. "Facial" refers to the face as a whole, which includes areas beyond just the mouth, and "dental" relates mostly to teeth and their health rather than the broader context of the mouth. Thus, "oral" is the most precise and widely accepted term for anything directly related to the mouth.
