One of the things that helps toothaches for us is to swish bourban on the tooth for as long as you can handle it. This offers some immediate relief usually. Then we apply Copaiba oil on the tooth and Clove oil. I also put Copaiba under the tongue. I then rub a mixture of Thieves and Purification diluted in coconut oil on the outside of the jaw over where the tooth is located and rub the remaining on my big toes and feet so the oils absorb into my body quickly. I continue this every 15 minutes until I find complete relief and then apply every few hours thereafter. No need to continue to swish the bourbon unless you just want to or the pain intensifies again. You have to address the infection and the Thieves and Purification do that. Peppermint added to this regimen increases the effectiveness of the oils you use, so I add a drop or two of Peppermint under my tongue and topically with the Thieves and Purification. Oils must be used frequently...they aren't a one and done thing. So keep forging ahead and be vigilant to get the infection and inflammation out. Continue to use several days after symptoms subside. I set an alarm on my phone for several times a day as a reminder.
To recap I use:
3-4 drops Copaiba under the tongue and on the tooth and gums and let sit for at least 30 seconds and then swallow. This has properties that may help with inflammation and pain.

2 drops Clove oil and 1-2 drops Peppermint oil diluted in about 1/4 tsp coconut or olive oil rubbed on the tooth and gums and let sit for a good minute. Swallow. These have properties that may relieve pain and inflammation as well as Clove oil has a high Orac value which goes into the body and kills free radicals.

2 drops Thieves and 2 drops Purification in 1/4 tsp olive oil along with a drop of Peppermint and rub on the outside of the mouth over the infected and surrounding teeth on each side of infected tooth. These have properties that may relieve pain, inflammation and kill bacteria, viruses and fungi.

I hope you find relief!
