Hi..
Can understand your concern..
It is really unfortunate that you are suffering from so much of problem.
In case the root piece is moved into the
sinus the first thing that has to be done is to get it removed followed by closing of the sinus perforation followed by antibiotics and painkillers.
For removal of root piece it depends on the location of root piece into the sinus.
If possible to remove it through the socket iodoform gauze can be placed inside the sinus through the socket to remove the root piece..
If not possible a surgical procedure is carried out in which a hole is drilled through the jaw bone and root is removed from the sinus.
The next part is that in order to close the perforation caused due to removal of teeth it can be done either by placing of gelfoam into the socket and placing stitches on the gum flaps by bringing them close together..
Slowly and gradually the opening gets closed..
You should immediately visit an ORAL SURGEON and get evaluated for the exact condition f the sinus and get treated accordingly..
Hoping you get well soon.
Thanks and regards..
