Persistent drainage and use of a cannula

Doctor, how should we proceed between appointments in abscess cases where drainage continues? Is leaving a cannula in the canal harmful?

Translated version of the Turkish original

We can stop drainage with frequent appointments over several days. I have never needed to use a cannula through the canal and do not prefer it.
