From past 2 months I found that there's something unusual smell coming from my throat. Firstly, I thought its because of oral cleanliness. But now I found it that it is coming from my nose as well. There's white fluid which has bad smell. Also I had a pain in my tooth (upper left) where I had done Root canal in my 7th satndard. My dentist told me that there is some white fluid coming from your tooth it's not good. Please tell me what's the issue I m really scared now. Help me please.
