48 hours ago I had a lower left molar pulled and a filling, there’s not been much pain if any until 3/4 hours ago where now there is a deep throbbing sensation on the extraction site. After taking a look it seems there’s also gone? But this piece of bone was actually visible whilst the tooth was still in so maybe it’s attached to the very back molar. I’m just scared of dry socket more than anything. Please see attached images and thanks for your opinions.
