Up until episode 17 of _Kimetsu no Yaiba_ , we see Nezuko no longer act like
the flesh-hungry demon she was when she first transformed, this is for a
couple of reasons that I can think of:

  1. She found her senses and understands family is a priority (as shown in ep. 1)
  2. In her 2+ years nap, her anatomy shifted (described by the doctor & mentor), to the point where the hunger is no longer killing her and she can act (somewhat) normally

But given these, why does she still need the mouthpiece? What's its purpose?
Also if she did still have the hunger, and it was being used as a
preventative, couldn't Tanjiro ask the doctor to make her be able to survive
on only blood?

Something doesn't add up.

Why does Nezuko still have a "muzzle"?


Remember that the main thing that Tanjiro is trying to do is find a way to
turn Nezuko back into a human. Also, at this point Nezuko is unique because
she's the only known demon who has never tasted human blood - even Tamayo and
Yushiro rely on allegedly humanely-sourced blood to survive - and it is
strongly suggested that this makes it more likely that she can be turned back.

Additionally, Urokodaki used hypnosis on Nezuko when she was sleeping to make
her see demons as the enemy and humans as friends. It's not clear whether this
is a long-term solution, or if there's a chance that it could wear off at some
point. If it does, and Nezuko winds up biting a human, then not only would she
potentially be un-saveable, but he and Tanjiro would be bound to kill her as
per his promise to the Demon Slayer Corps.

Therefore, Nezuko wears the muzzle to ensure that she never has a chance to
taste human blood, either because the hypnosis wears off or just through
random chance (for example, in the heat of battle she could wind up biting
someone or just getting blood splashed in her mouth from someone's wound).
