dental abscess
"I have had an abcess in the same tooth 3 times now over the past 7/8 years the problem is its a front one so my dentist is reluctant to remove it. As I have had it a few times now I can tell the strange sensation a mile of as it is coming on before the real pain starts which might I add is probably the worst pain I have ever endured. So I went straight to the dentist. Because I caught it early this time he didn't want to perform a root canal and prescribed me with metronidazole 400mg 3 a day for 5 days I have had amoxicillin previously and it didn't work properly and had to have 2 root canals in short succession (not pleasant). I'm now on day 4 the swelling has decreased considerably  very impressed with this medication"
