First of all, please don't panic. Fear will not make the problem go away, it's just going to give you something else to deal with and this problem will be resolved at some point.
The post operative instructions to not blow your nose (for about a week!!) is suppose to be given to all patients who have had upper molar extractions. If you have to sneeze, keep your mouth open to avoid pressure in the sinuses. Also, do not drink through a straw, smoke, drink alcohol or rinse with any mouthwash containing alcohol or essential oils. All of those things will prevent the surgical area from closing over.
If the dentist said "a root has gone up into your sinus" this generally means that part of the root was fractured off during the extraction and he pushed it up into the sinus while trying to retrieve it. Depending on where the root is, it may work it's way down and eventually poke a hole through the gum as if you were teething. This would be the best case scenerio.... then a dentist could remove it without difficulty.
The big issue here is the risk of infection. So it is wise to take the antibiotic and be diligent with your post operative instructions including rinsing with warm salt water starting 24 hours from now. If water runs out of your nose when you drink or rinse, then you need to go back to your dentist as this means that the sinus has not closed over. If now or in the future you develop unusual sinus congestion, pain or a bloody nasal discharge, then you would need to see an oral surgeon to evaluate where the root is and determine if there is any pathology going on.
This situation does occur from time to time.... if you are symptom free once the extraction site has healed closed, then it is best to have the area evaluated 1-2 times a year with an xray at your dental office to see where the root is and if there are any unfavorable changes occuring in that area.
Were you planning on replacing this extracted tooth with an implant?

I have been given a pile of antibiotics and an order NOT to sneeze ever again (well, for a day or so).
So far the other posts give me the fear.... I have the fear!
What to do?
