I had mine out at 20 (and I was diabetic at the time). Diabetics are more prone to “dry socket”, they say - and I did have trouble with that. Not much to do to prevent it, other than follow the doc’s instructions to the letter. I only had it in one place - and it was resolved within about 3 days. The pain meds made it seem not so bad. 
I’d really recommend using the little syringe 'squirter" they give you to keep it cleansed of any food particles - I think that’s one reason mine never healed up completely - after 20 years food can still get stuck back there!
All in all - it wasn’t too bad. Hang in there and it’ll be over soon!
