What to Eat Post-Wisdom Tooth Surgery

I'm getting my wisdom teeth removed in 2 weeks. I was contemplating doing a juice cleanse for a few days after, since I won't really be able to eat much anyway. Is there any reason this might be unsafe right after the surgery?

I'm worried that it might take me longer than average to recover because my mouth is very small and my wisdom teeth have been bothering me a lot. Are there any foods or drinks that you guys can recommend? I still want to eat healthy during this time. I'm actually hoping to shed those last few pounds since I won't be able to eat much, then use MFP to maintain after. Also, dairy is off-limits for me.
