BETTER BUT WITH SIDE EFFECTS
I recently used HP because of a tooth abscess. I swished about 1-1/2 tsp undiluted over the counter HP a couple of times. I must say it did help with the abscess tooth pain. Unfortunately, several days later, I noticed an extreme sensitivity of my teeth to hot and cold. I can only assume it was from the HP. Has anyone else had this experience? I haven't found anything thus far on the website that indicates that HP can harm your teeth in this way. I'm puzzled! I am still having trouble with that particular tooth abscess but am now reluctant to swish any more HP until I can find out what I've done wrong. I did not mix it with water and maybe that was the problem? Anyone with some feedback would be very welcome to respond!
