Scot, there is no doubt..it is absolutely the OP. We've heard this same story over and over.
Now, if you want to really WOW your dentist, add a few drops of Oil of Oregano to your pulls, once a day for a about 8 days. But no more. There will be no inflammation, infections, or anything. It's like taking an antibiotic.
By changing your oil to Sesame, I wouldn't be surprised if you have even further, good results.
