Every check up ends with a sheet. On it: what the dentist found, tooth by tooth, what they suggest doing about each one, what each of those things costs, and what happens if you do nothing for now.
You take it away. Nothing on it is booked at the desk unless you ask for it to be, and nobody will ring you about it. If you come back in six months with the same sheet, we will look again and tell you what has changed, because some of it will have.
This is also why no treatment is done in a check up appointment. A plan agreed while somebody is lying in a chair with a light in their eyes is not a plan anybody agreed to.
