It sounds as though your dentist has tried all reasonable treatments to save the tooth. After two failed root canals and an apicoectomy, extraction sounds reasonable. Any other efforts to save this tooth would be heroic at best with a poor prognosis, based on past treatments. At worst, it will be a complete waste of time and money. Furthermore, any further delay in effectively treating this infection could result in serious complications to adjacent teeth and other parts of the face. Depending on your individual situation, your dentist may be able to recommend treatment to replace the lost tooth. This might include a dental implant, a fixed bridge, or removable partial. Ask your dentist to explain your options.
When a tooth is pulled and when you rinse and water comes out of your nose, this is a sign of an oral fistula. An oral fistula is a hole from the extraction site into the sinus cavity. You will need to return to your dentist for treatment.

An artificial shunt for hemodialysis, either a fistula (direct artery to vein connection) or a graft (artery to vein connection through Goretex tubing), can be on the arm, or preferably on the forearm for a fistula. A fistula, and even less so a Goretex, will not burst because of applying pressure through a sphygmomanometer (which was the original answer posted here). There is a slight risk of causing a thrombosis of the venous side of the fistula, particularly if there is already a venous stenosis.
Fistulectomy is surgical removal of a fistula.
