I have this bitter taste in my mouth. It's been this way for 2 days. Could it be from an abcessed tooth with

no pain? I have a broken tooth but there are no other symptoms of an abcess no swelling nothing. But I have this bitter/metalic taste and it especially tastes worse after eating or drinking.. ANy ideas on what this could be?

I'm experiencing this same thing right now. I'm not pregnant. I know I'm healthy otherwise. I did find this interesting forum on the web where people are reporting that after eating pine nuts, they get episodes of the bitterness after eating or drinking.

I've also read that post nasal drip might cause this. I hope you get some relief. If I find anything else out I'll post you another answer.
