Hi, it does sound as if your wife has a dry socket. It occurs when the the blood clot in the extraction site was lost. This can occur 1-3 days following an extraction and leads to extreme discomfort and extends the healing time. Dry sockets normally heal from the bottom up on their own with no treatment required. Exposed bone is what causes the pain. Once a new clot forms and granulation tissue covers the exposed bone your discomfort will disappear. It could take 10-14 days for this to occur and as long as 4-6 weeks for total healing!
There are no restrictions when eating. She can have whatever she likes..
At your local drugstore you can get some gauze and cut it so it is about 3/4 of an inch square and apply some Zinc Oxide Ointment or Desitin Ointment on it and put it in her socket. The pain relief should be almost immediate! However, this does need to be removed in 48 hours. Packing the socket with oil of clove gauze is standard treatment.
If it is no longer exposed then it should be left alone granulate and heal. Since she is in extreme pain now she should make her own oil of clove dressing.
This video will show you what and how to do it:
She needs to take 2 Advil (400mg) every 4-6 hours along with 2 Tylenol (650 mg) every 4-6 hours. Please do not use this regimen if there is a history of peptic ulcer or liver disease or if you are taking blood thinners. This combination is as effective as a prescription medication. Advil and Tylenol together is as strong as a narcotic and works even better.
Unfortunately for your wife exposed bone is very painful and once the bone is covered with some granulation tissue she will be much more comfortable. Does this answer your question?
