Sarah comes to Peter/Peter's

[EngLearner]

I wrote this as a context for one of my threads:

John comes to Peter's house with a pizza. Peter puts it on the kitchen table, then they have a short conversation, and then John leaves. Then Sarah comes to Peter, they go to the living room, sit down and start talking. After a while, Peter remembers about the pizza and says to Sarah:

In the movies I've watched, I've heard people say something like "Let's go to John's." when they want to go to someone's place. I wonder if in the passage I wrote I should've said "...Sarah comes to Peter's..." or if my version is also OK.

Yes, you should. No, your original version is wrong.

It would make more sense to say "Later, Sarah arrives". It's clear that the setting is Peter's house.

Does "To go to the dentist." mean to go to where he works, and does "To go to the dentist's" mean to go to where he lives?

No.

"To go to the dentist's"

Is saying it like that incorrect? If not, what does it mean?

It's not wrong. Some people say "I'm going to the dentist" and some say "I'm going to the dentist's". In both cases, they mean that they're going for a dental appointment, wherever it is their dentist works.
