Being a music teacher/guitar teacher i have had to take some test on emergency situations and also i have gone through one root canal and when it comes to tooth aches and tooth pain, some great pain relievers are pure vodka(don't drink, just use as mouth wash), Honey( honey will sooth the throat which can sooth the nerves also), Another is prescribed medication and antibiotics from your dentist or endodontist, and hot black tea with some lemon in it
