I have had a hole in my back tooth for some time and now I have to make an appointment with a surgeon, but the waiting time there is long. Now pus has formed under the tooth and the whole side of my face hurts. How can I get the pus out, since the entire side of my face and also my ear hurt? Thank you.

Dear Sir/Madam!

If this really is a purulent inflammation in the area of the root apex of the tooth described, the abscess must be drained (emptied). Drainage most often has to be performed in two ways:
-trepanation of the tooth, which allows the pus to drain outward through the root canals and the drilled tooth crown,
-incision of the swelling (if it is already present), which allows the pus to drain through the incision.
Later, once the acute inflammation has subsided, the tooth must undergo root canal treatment or be removed. I recommend X-ray diagnostics.

Have a nice day!
