8 days post-op simple wisdom tooth extraction. sutures are out. small hole left behind. how long on average for it to close? i've read it heals from the bottom up so to expel foreign matter.

Few more days: Everyone heals slightly differently, but it appears you are healing normally. In another few days you should be fine.

Accurate information: No two people heal exactly the same way. The average non-smoker may take up to 4-6 weeks for the gum tissue to fully heal. Smokers have been known to take much longer. Common sense comes into play with regards to incorporating a normal diet. If it feels like its too soon to start chewing normally- it probably is.

3 weeks: At 36 years old your healing will be a bit slower but the holes should close up at about 3 weeks. Check with your oral surgeon after that if you are still not satisfied.

Several weeks: It is not uncommon for an extraction site that was not partially closed with a gum flap to take several weeks to close, especially if a dry socket occurs (premature breakdown of the blood clot within the socket). It takes quite a while for the socket to fill with new tissues that will turn into bone. As that is happening, the gum will grow from the sides toward the center, making the hole smaller.

It depends but: Approximatley 10 days to 2 weeks for initial surface closer in most cases. This can vary depending upon your general health, age, how well the area is kept clean and your body's healing ability.

True,: Heals by secondary intention. Socket fills in anywhere from 6-12 weeks. Helpful to be able to flush the socket with a plastic syringe. Can get this from most oral surgeons.
