Question about complication/pain after tooth extraction..Please read details (too much to write here!)?

Ok so I had a lower molar extracted 5 days ago and after the 3rd day it still seemed to hurt pretty bad but i thought maybe it was just because the tooth was very hard to get out. The 4th day, yesterday, it started to be EXCRUSIATING plus I started to see a bit of white shoing on the side of my gums where the tooth was pulled and it now has become jagged and sharp and it's cutting the **** out of the side of my tongue! it hurts bad! So I'm wondering what in the world that is...PLUS, I went to the emergency room last night because of the pain being so bad and the dentist being closed for the holiday and the emergency room didnt have much to say but it didnt look infected. they gave me 2 Perkasets and a Rx for Vicodin. The pain is SO much better. I was thinking I have dry socket but I hear that pain killers do not help the pain of dry socket at all, so maybe that not what the problem is? And I also would like to know what the jagged little white thing is that just appeared in my gum. TY!

Probably a piece of the tooth. It is very common for the dentist to have to remove the tooth in pieces. And sometimes they miss a tiny piece. I know it doesn't feel tiny, but it really is. Call the dentist and make an appointment to go in. He/she can pull that little piece out with no pain at all. They can take another xray to make sure they got it all. Shouldn't cost you anything more because it's related to the extraction. So no worries. That pain could be that piece of tooth working it's way out. But see the dentist to make sure.
Reply:I agree with bmac but would also like to add that it does sound like a dry socket. And that the white piece could also be a piece of bone. I know that sounds really bad but a chip of bone will work out just like a chip of tooth. It is more than likely tooth though. See your dentist, you may need to have that socket packed.
Reply:If the area is still in that much pain contact your dentist, the pain killers may help for now, but it does sound like a partial or complete dry socket. The jagged edge can be either a small piece of tooth, a calculus spur that may have been on the tooth prior to extraction and has not fallen into the socket area and become an irritant, or a bone spur which is a jagged edge of bone on the area surrounding the tooth and is now noticeable since the tooth is gone. At any rate, a dentist needs to follow-up, even on a holiday weekends they MUST have an answering service or phone # where they can be reached, that is the law. Emergency rooms are good for a little meds to hold you over until you get to see your dentist, Emergency rooms do not usually perform dental procedures, at least they don't in our area, and the only dentist with hospital rights are Oral Surgeons.
