I'm curious what these reasons are

(My second thought after typing that was "I suppose I could just ask an LLM though")

There are 'best to brush' timelines around eating/drinking. Usually you want to either:

- Brush no less than 15m before eating

- Do not brush until 45m+ after eating

I don't fully understand the science, as I'm not a dentist, but it's something related to the way that things stick to/are absorbed by enamel and dentin.

I believe water is the exception here, you can drink water and then immediately brush. You should not brush and then immediately drink water though. You want the toothpaste to stick around and form a barrier.

Supposedly, after eating the pH in the mouth drops and becomes more acidic, which softens the enamel, so brushing will do more harm than good. That's my understanding.
