Things to know on post-op care?

For context, I got all 4 out at the same time (bottom 2 were grown in sideways, top 2 normal), and I’m 21F. My doctor gave me a little care guide but just looking for more things I should be aware of. Right now the pain is a 6/10 only when I’ve tried to eat. Should I be brushing after every meal now? Should I lightly swish some salt water around?
