Saginaw, I : Saginaw, i truly don't know how things were handled, but a bad smell and soreness tells me it is not right now. Not everything turns out the way we want it to.

I had a 2nd root canal performed yesterday after an abcess was diagnosed. Is it normal to still have pus on my gum after the procedure?

Keep an eye on it: Unfortunately, root canal treatments can have recurring infections for several reasons. What is important, in my opinion, is to resolve the infection prior to completing the root canal therapy. If it was completed in the presence of active infection, you will need to monitor it closely. If taking antibiotics, the pus should resolve, but could still return later. Pus never really is normal. ...Read more

I got an old root canal retreated this past tues due to abscess. Dr put meds and temp crown on it til appt in 2 wks. Abscess seems worse. Normal?

Endo retreatment: Whenever a n old root canal is retreated, it is normal for the tooth to be more sensitive than before. The removal of the root canal filling is more laborious that taking out the pulp tissues. It is always possible to take the files outside of the root into the surrounding bone and cause some post op pain. Continue the medication as prescribed and check back with the dentist if symptoms worsen. ...Read more
