I had a extraction 4 days ago and am now experiencing pain. i can actually see the bone area. and can't reach my dentist should i use periogard (chlorhexidine gluconate)?

Dry Socket Possible: Call your dentist asap. You could possibly have a dry socket resulting from loss of the blood clot in the extraction site. This area needs to be packed with a dressing that will cover the area to help it heal and to alleviate your discomfort. I would talk to your dentist before using the Perioguard rinse, just to be on the safe side.

Yes: Post dental extraction may cause dry socket pain, as well as pain resulting from irritation of the root, and surrounding structure, including the gum. Chlorhexidine mouth rinse, such as Perigard or Peridex (chlorhexidine gluconate) can decrease post extraction infection. If you experienced increase pain, you may need to consult your dentist for further evaluation.
