I had "major" dental work done not too long ago and thanks to many posters here on CZ felt confident enough not to take Antibiotics ... well there was no infection involved. And thank God, "mine" did´nt get to that stage. Thanks to gargling with Oregano Oil and taking a good "Schuss" of Vit. C with every glass of water I drank... also eating well - must have done the trick!
Just recently found out on the CZ search machine that the Antibiotic the doc prescribed for a urinary tract infection was the last thing I needed. So would recommend you do a search if the Antibiotic you´ll be taking is OK.
