I have really bad teeth in general and have used this remedy for years with straight 3% HP. Works beautifully and I highly recommend if you can't get to a dentist for proper treatment.

Not knowing much about hydrogen peroxide but wanting to get a tooth abscess under control I went to the health food store and bought 35% HP as I was dizzy and concerned. I diluted it according to directions, 1oz to 11oz of water and that would create a 3% HP solution. I swished it in my mouth and it foamed big time. Can't tell you exactly how long I swished for cause it was really strong so not for very long but instantly I felt so much better. No more dizziness. No more tooth discomfort.

I came upon this site because that was a couple years ago and I am having issues again and wanted to try the HP again so checking here for strength and dilutions again. I agree... teeth should be able to be healed. I have used calcium to recalcify a black cavity my daughter had in a new 6 yr molar. That took 4 months of double the amount of suggested calcium, but the cavity was completely gone. Most everything else in the body can be healed and restored, so why not teeth. I am avoiding a root canal cause I do not want the infection to be locked in the body and show up later somewhere else. Any other suggestions for healing teeth totally to the root, cracks included is so welcomed!

Peroxide is great, I use food grade also and dilute it appropriately, it's especially great for bacterial infections, but you have to get it to the source of infection, it even kills cancer if you can break through the viral cyst. But essential oil of clove is even better for impacted teeth, tooth pain, etc, and it penetrates much deeper than peroxide.

For tooth pain, I first tried the garlic remedy, but the pain-free effect only lasted for a short time. I saw the Earth Clinic editors' recommendations and tried the peroxide swish. (1 capful peroxide. Swish for 5 minutes) Pain gone! I repeat this about every month or so just to make sure there is no recurrence. Simple, cheap, fast, and effective. Thanks, Earth Clinic.

I had a painful tooth that was throbbing last year. It's dangerous to let a dental infection fester, however I was not in an area where dental care was an option. I tipped a capful of peroxide in my mouth and tilted my head so it reached the infected tooth. I did NOT swish the peroxide around, just let it foam up. When the liquid was gone and only foam, I spit the peroxide out, rinsed my mouth out and proceeded to do it again with another capful. I did this 3 times. On the third time there was less bubbling up so I knew the peroxide treated the bacteria. Remarkably no pain the next day or thereafter but my tongue was sore from the peroxide.

I have a tooth that hurts maybe once a day, generally at night mostly, and sometimes during the day. I keep strong salt water nearby or plain water to swish my mouth out, the pain subsides within a few minutes. I may go several days without pain and if it does flair up I just put straight Himalayan pink salt there, swish it around the base of the tooth and the pain subsides within a minute or so. Use just a small amount. I also use garlic in the morning. Every time the pain starts, swish. I put peroxide or half vinegar and half alcohol mixed in my ear. The peroxide works best for me.

I had a painful toothache from one of my top molars, the tooth had broken in half actually, and I was in a lot of pain. But that was almost 11 months ago :) Hydrogen peroxide works!! I brushed my teeth with baking soda, rinsed. Then swished a little HP for a few minutes (let it foam), then spit it out and rinsed with a little warm water. Again, that was 11 months ago, and I have absolutely no pain in that tooth, it's still there.

I'll make this quick. Tooth abscess, not eating, not sleeping, and terrible pain. A tablespoon of Peroxide mixed with 2 tablespoons of water. Just let it sit in my mouth for about 30 seconds. Pain slowly started going away. About 10 minutes later I tasted something in my mouth. Grabbed a paper towel and there it was. Abscess blood and pus. Rinsed again and was instantly back to normal. Wow! It worked so quickly, wish I knew sooner.

I used 50/50 water and hydrogen peroxide. Swished for 2 min, spat, rinsed, and repeated after about 5 min. (2 min because that's as much as I could take before it got too foamy.)

When I had a tooth infection a decade ago, a dentist gave me a prescription Hydrogen Peroxide mouthwash. I came upon this site trying to find a DIY version.

I have had a broken molar for years, but was able to keep it clean and happy with oil pulling and obsessive flossing until about 5 months ago. At that time, it started becoming very sensitive to cold and heat. This winter I couldn't open my mouth outdoors because the cold air would go right into my tooth and give me a blinding headache for hours. Eventually the gums around it became constantly swollen, tooth became painful to touch, and i'd get a massive tooth/headache every night. Advil/Tylenol did nothing. Was on antibiotics recently for something else, and that did nothing for my tooth. This past week I haven't been able to chew on that side of my mouth. I assumed this meant the broken tooth was finally dying.

This evening, in great pain, I finally tried the 50/50 peroxide water. Painful at first, but by the end of the swish it had improved about 10%. I thought that would be it, and that I'd just have to continue this regimen for a few days to see any major improvement. 2 hours later, it has improved 60%. The tooth is not painful to touch, the swelling has gone down massively, though it's still sensitive to cool air. No pus but my gums are steadily releasing something like salt water, and a tiny bit of some hard foreign substance has been ejected along with the liquid. Maybe popcorn kernel? broken piece of tooth? I might be up all night spitting out salt water, but I'm without pain for the first time in months. I'll take it!

I drained my abscess with 3% hydrogen peroxide and paired it with antiseptic mouth wash and massaged the area with my thumb to push the pus up and out. I had the worst pain while doing this but I pushed through it. I was starting to get lock jaw so in order to fix this I actually killed two birds with one stone. Fast forward to two weeks ago I got my wisdom tooth pulled and a couple days later I noticed the taste in my mouth was funny, but there was that unpleasant taste of pus I couldn't mistake. So I started rinsing with peroxide and salt water until I was cleared to use mouthwash again. So far so good; the pain has somewhat gone away but the swelling in my gums is still there. I'll continue to use the peroxide until I go to my check up next week. Peroxide worked wonders.

I found that Hydrogen Peroxide stopped my toothache, I have tried other remedies but nothing worked.

Hi everybody. I'm 65. Ten years ago all of my upper teeth were hurting. Dentist told me to yank them all and get dentures. $3 to $4 thousand smackers! The big hunt for a natural cure began. Found Hydrogen Peroxide. Brushed my teeth with a cap full of 3% HP two times a day for 2 days. Let it foam for about 5 minutes. Pain free after that. Here I am 10 years later with all of those teeth that the dentist told me to yank except one. I still brush with HP once a week. My teeth are doing GREAT! Thanx for the opportunity to help someone else. - Bill

My abscess is 100% gone after using the Peroxide method. What I did was boil a sewing needle for 10 minutes to sterilize it, I poked the abscess a few times and then pressed on it and drained it all out. I immediately swished straight 3% peroxide afterwards. It turned the gum (Where the abscess was) white for half an hour which was the infection being killed. I continued using peroxide for several days after. It's been over a week now and the abscess has not returned and the pain is gone. So relieved!

I had similar results injecting HP in the abscess region. Yes the pain was intense. It took several tries but after more than a week the abscess is not active. Did it kill the infection deep in the tooth? No idea. But since there is no puss being produced, it just may have done that. Did it feel risky? Yes. I would not have done it if the antibiotics had seemed to be working.

As to the safety: I seriously doubt it could trigger an infection as it clears bacteria in its path. I wish I had tried this earlier with a tooth that eventually rotted, broke and was finally pulled.

Tooth abscess for second time after 6 months -

I used hydrogen peroxide every hour for one day. Next day swelling and pain were gone. Antibiotics are in the trash can and I am cancelling my root canal appointment.

Also going to buy a bottle of colloidal silver and use it once a week to make sure no more infections occur.
