Can swelling occur on the face after an incomplete RCT?

Hello doctor,

My dentist did half of the root canal treatment, filled it in, and sent me home. Recently the filling has fallen out and I have not been able to get to a dentist. My tooth does not hurt, it occasionally tastes of blood, however, my cheek and gums have swelled immensely this past hour, and the swelling has even reached my lower eyelid. I put clove oil on my gums and tooth, left it for 20 minutes, and then rinsed my mouth seven times with salt water solution. I took some anti-inflammatory tablets (Amitriptyline, I am on this anti-inflammatory for a chronic pain injury residing in my spine and rib cage, it is the only anti-inflammatory my body has responded to. Others such as Celecoxib and Mobic did not work, and over-the-counter medicines did not work either). I had been holding ice to the swelling for 20 minutes every 30 to 40 minutes. But the swelling has not even decreased, it has increased to around the lower eyelid. Please help me find a way to reduce this swelling.

I do not have any pain. It is simply sore from the amount of swelling there is. Does this have anything to do with the unfinished root canal? Please help.

Thank you.
