Mermy before you decide...there are erupted wisdom teeth, and impacted wisdom teeth. If impacted, they are tissue impacted or bone impacted. (jdarg-look away) Fully erupted wisdom teeth are realtively easy to remove, the roots are shorter and the upper ones usually roll out. Recovery is fast with little puffiness if you take it easy and use ice the first 24 hours.
Tissue impacted is a bit harder, they make an incision in the gum, then remove the tooth. Bone impacted means they cut through the tissue, drill through the bone and remove the tooth, usually in peices. This is the one with the most difficult recovery time. But even then she may bounce back quicker than you think. Removal on Friday, she would feel good by Monday (maybe Tuesday if she didn't follow instructions to the letter). It's important to follow the directions exactly, ice on and off as directed, the swelling equates to pain. No vigorious spitting ( but don't swallow the blood, makes the tummy sick), don't smoke, don't use a straw. You are trying to not dislodge the blood clot in the socket, this is the dry socket you've heard of and the nerve is protected by the blood clot. (sorry jdarg I told you to look away)
If Fyl has erupting teeth that are trying to come in she may trap food between the tissue and the tooth as it tries to erupt, this is painful and can lead to infection. She's teething just like when she was a baby so it's uncomfortable, but not an emergency. Just be extra diligent to keep that clean, a water pik helps or rinse with a peroxide mouth rinse to bubble the trapped debris. If she has bone impacted teeth they can actually be sitting in her jaw sideways with the biting surface of the tooth pushing on the last molar, leaving it can damage that molar. Even if they are not impacted they can crowd the existing teeth shoving them out of alignment and messing up her occlusion. If it messes up her bite, she'll get headaches etc. So it may be best to not wait too long. I'd try to get her set up by Christmas break just in case.
My daughter had all 4 removed at once, all impacted. Two were soft tissue impacted the other bone impacted and sideways. The bone impacted was what caused her the most pain. Removed Friday, nasty day, lots of meds and ice ready. She was up on her feet Monday with little swelling. I watched her like a hawk the first 24 hours I'd seen too many dry sockets in our office and didn't want that. Sorry that was long. Let us know what you decide.
