I’ve personally tried using peroxide for toothache. I could tell you that it gets rid of the pain instantly but it’s not a permanent fix. In order to get rid of this pain you would have to purchase something called clove essential oil. It’s made from real cloves and it is distilled and bottled into a oil.
Honestly it’s just a quick fix and may last up to an hour besides that you’re just making the pain worse. I believe that peroxide in flames the gums and also dries out your tongue tremendously.
A lot of people are gonna say peroxide works but there’s things that it does to other parts of your body in order to dry it out and cause irritation. So definitely be careful using peroxide. I have articles on clove oil and how jit works. Some of my articles below will show you how to use it properly in order to get rid of your toothache infection.
