Healing after wisdom teeth extraction

Hi all,

My boyfriend is having all four of his wisdom teeth extracted today. They are all impacted, so the extractions will involve surgery.

I would like to ask for advice as to what he should do in order to facilitate the healing process.

I suggested he should abstain from eating/chewing for as long as possible, preferably a couple of days, and to only drink through a straw (tea and water).

Please let me know what you recommend.

Thanks!
