I went to a dentist on Monday and they removed an old filling of a root canal. They packed it with some kind of Chinese medicine to soften the tooth so they could insert a stabaliizer before refilling it. Two nights later my right eye became very puffy when I woke up. Today it is even puffier and swollen. Is there any connection between the puffiness and what happened at the dentist? They did not give me an antibiotic. We live in China and the way dentistry is practiced here is different than in the West.
