bacterial infection
"Tooth infection. After taking 5 of the 28 pills I had the worst heartburn of my life and could not even lay down. After 10 of them I ended up in the ER with chest pains, excruciating heartburn, diarrhea, and the itchiest hives from head to toe. They were however very effective at clearing up the infection which in turn reduced the pain in my mouth significantly. So for me, where tooth pain is almost intolerable it was a trade off I accept."
