I used (rinsed with) apple cider vinegar yesterday in the hopes that it would help with what might be a tooth infection. In my ignorance, I brushed my teeth (with electric toothbrush) right after using the vinegar. As I brushed, I thought that I had somehow broken all of my teeth and all the nerves were firing and the pain was excruciating! Side note: I have a mouth full of receding gums. I have been in excruciating pain every since. Does anyone know of anything that might help?
