My experience, as quoted from another thread:
Had mine out over 20 years ago. All 4 removed at once under general anesthetic, 2 were impacted IIRC.
I was probably the most miserable that I have ever been afterward. Swelling was terrible; so swollen that my jaw couldn’t be in its “normal” rest position, so the muscles ached. The stitches in my mouth felt like they were made of heavy rope. They were so annoying that I removed them myself the next day with needle nosed pliers! (Yes, I’m a model patient). That did not make my mom real happy; she called the dental surgeon in a real panic! But, I survived. I had bruising on my neck for at least 3 weeks afterward.
Glad its only a one time thing!!!
