Question: The second upper tooth (filled, the nerve is not removed) was very painful. Flux came out, and then a fistula (two days later it burst). I went to the doctor, she tried to insert the drainage … It did not work, said the hole is very large fall out. Told me to squeeze out the pus myself slowly.
Answer: You need to see a dentist for re-examination and make an image of the tooth, only after that it will be clear what was the reason for this inflammatory process and respectively take measures to eliminate it. If the doctor decides to drain the tooth, the root canals should be opened and endodontic treatment performed, only then the positive result of treatment will occur. But the final word will be given to the attending doctor who sees the clinical situation visually.
