My cavitation dentist in Bellevue, Wa.
suggested that during root canal extraction is get lined up with IV'S pre and post surgery this is so important it can stop the infection from settling elsewhere in the body.
Also insist they send the contents of the finding to the lab so it can be identified and a cavitation dentist will know what lab may not be covered by your insurance . I had to pay out of pocket for the lab since no regular hospital labs do this racked on 300. To my bill.
