yes I can vouch for that method...had a very bad swolen jaw due to an abcess...dentist said you will have to wait it out with painkillers and anti-biotics...no way got an old retired arm doctor to make a hole in the jaw with syringe...result 1 minute of the most foul tasting liquid ever imaginable..but instant pain relief...had to swallow salty water for a couple of days...but no further problems...old ways are the best..Happy Canada Day to you all cheers malcolm
