How do you replace The dentist said open wide with a pronoun?

You can replace "The dentist said open wide" with a pronoun depending on the context.

Here are some options:

* He/She said open wide: This works if the context makes it clear who the dentist is.

* They said open wide: This works if the dentist's gender is unknown or if you want to use a gender-neutral pronoun.

* The dentist instructed me to open wide: This is a more formal way to phrase it, but it avoids using a pronoun entirely.

Ultimately, the best way to replace the phrase depends on the specific situation and the tone you want to convey.
