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 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'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''m not going to give anyone a bunch of bs. by talking about garlic cloves or dentist's so here goes..."I have to have all my teeth pulled but in insurance". I've had several abscesses and all I did was to massage the sore area until the pain subsided and then put about 2-3 cap's of Hydrogen Peroxide in my mouth and saturate the painful area with the HP. The pain will pass almost instantly and since I have several bad teeth, rinsing with HP once or twice a day and letting it foam up in my mouth heads off any further flareups.

"IT'S ALL THAT SIMPLE "! I Should add "I did have a puss bag on my outer gums" so I sterilized a needle and lanced it a few times to empty it, adding pressure on my face to make it drain "then put some HP (APPROXIMATELY 1 OZ.) in my mouth and let it foam to kill the infected puss. "ALL MY PAIN WAS GONE IN 5 MINUTES "!! NOW JUST RINSE YR MOUTH AND HAVE A BETTER DAY......JACK

Worked Temporarily

I put hydrogen peroxide on a cotton ball and held it on my gum boil rubbed it a bit until it released the boil Today the gum boil returned. Did this once before. Gum boil returned. I was told it will keep coming back until I get root canal? Should I keep trying? Maybe I should pop it first? Also have an abcess on my gum. Don't want to pull teeth.

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.

I have a cavity in one of my wisdom teeth. I started using Hydrogen peroxide as a rinse to keep the germs away. My tooth did have some tenderness in it at first. But then the pain went away completely. I just now came upon this article. Three cheers for Hydrogen Peroxide! It is nice to see the info I gained as well. All I did was swish some peroxide around the inside of my mouth. I made sure it went inside the cavity. kept it in my mouth for about 2 or 3 minutes. Spit it out. Then rinsed with warm water. spit it out. Then for good measure I rinsed again with a little mouthwash. I did this right before I went to bed after I brushed my teeth. And again in the morning. I am waiting for a dentist appointment. it is nice not to have any pain while I wait.

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.

Update: 7 months later and the abscess has not returned! HP is WONDERFUL! Also a cavity of mine was giving me almost unbearable pain today, swooshed some 3% HP on the cavity and the pain is gone. So glad I found this website :)

I would like to add to my dental post here. Borax foot soak using a pinch in 2 gal of water once a week made my bad teeth hurt worse the next day, then they seem to be improved. Like it's healing them. I suspect lack of borax has made the calcium go in the soft tissues and not my bones/teeth over the years.

As far as dental pain goes.... I have rode the rodeo....been to the dentist and had the works done( 9 crowns, some root canals, & partials ) and then lost ten teeth while following that program.., due to the teeth worked on abscessing... all that money spent has taught me painful lessons about the system I had trusted. Flouride is bad for your bones and teeth and organs. Hitler used it to make people docile.

Alpha lipoic acid helps a lot for nerve pain. MIX a Tbsp each of baking soda & coconut oil with a drop of peppermint oil, at bedtime...APPLY a small amount of this mix on gums and teeth and head off for a good nights sleep. Works wonders .Get ALL your vitamins, amino acids and water, minerals in balance and detox your body . You can restore your youth . Keep studying and don't believe everything you read.

If you do use the borax get ready for a rodeo ride for awhile....still expecting miracles, because I have faith in the one who designed my teeth . Amen

read earth clinic, go to youtube, and lots of other good sites, as your own library . Just because it's at your local library you can't go blindly trusting it to be the truth that heals you.

google regenerate teeth, people have found ways for teeth to heal & regrow and some have received prayer miracles. God is good all the time, even if he shows up at the last minute. He's stretching my faith, as usual.

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!

Garlic works wonders for all things tooth pain related. I've noticed that many others here do as well.

Slice up a clove of raw garlic and have him put it on the gums surrounding the angry tooth or abscess. He can hold it in place with his tongue, or even his fingers, if necessary.

It will burn a bit at first, but don't let that deter him. Have him move the garlic slice from one side of the tooth to the other for about 10 minutes. Repeat this a few times a day. The more, the better, but at least 3-4x/day.

Through trial and error, I found that the garlic method works even quicker if you also take the garlic internally. If you give him a clove or two of chopped-up garlic to swallow about 3-4 times a day, it helps expedite the healing process.

Also, rinsing with warm salted water in between helps heal, too. Have him gently swish the saltwater around the affected area for about a minute, then repeat the saltwater rinses a few times day/night.

The last time I had a tooth issue, my tooth was so infected that my jaw and part of my face was swollen, and the pain...UGH! Yet, as bad as the infection was, using the methods I described above, I was pain-free within just days! The best part? That tooth hasn't bothered me since, and it's been about 2 years! :)

Good luck!

Its been a month and I have had no further need for injections. The abscess is gone although a slight depression remains where it was. I still sometimes feel a slight pressure in the region (swimming under water for instance) but no signs of infection. How my body is handling the cavities is anybody's guess, but for the time being I am managing and I feel more dentally empowered.

I wanted make one last follow up. My report of 09/12/2016 was a little pre-mature. I had to go in again with the H2O2 injection. I used a different angle, forced the remaining infective core out and have had no problems since then. Just mustering up the courage to do the initial injection was the hardest part. Subsequent follow-ups were uncomfortable but not scary. Follow through made the difference. My infected gum and bone is completely free of infection. The first sign of eruption took place following dental work more than 20 years earlier. Why didn't I know I could manage it this way back then? It would have seemed too radical a move for me, but watching and waiting did nothing other than probably shorten my life. Oh well. Its not a problem anymore.

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.

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.

HP is awesome!

I have a partially erupted wisdom tooth, so a few days ago I developed pericoronitis from it. The pain sucked and kept me up at night. Tried several different remedies, garlic, saltwater, even some chlorhexadine and silver sulfadiazine I had on hand, but nothing seemed to work well. Yesterday I bought 3% hydrogen peroxide and used it undiluted, using a needle and syringe to spray the HP between my gum flap and tooth (not poking myself, just using it like a small water pick) I'd let it foam out, repeat a few times, then finish it with a dose of chlorhexadin to seal my gums. Went to bed and woke up with practically no pain, and not hardly any pain throughout the day. I've always been a huge fan of HP. Once when I was younger I developed a localized MRSA skin infection, lanced it and bandaged some HP soaked gauze over it and it was healed overnight as well. I'm only rating it 4 stars atm because I'm still not 100% healed yet, and I'm not sure if it was strictly the HP that fixed my pain or not, but it sure seemed like it. :)

After seeing a dentist friend about an abscess I made an appointment and he recommended an oral surgeon for two molars 19 and 20. this was 12/20/16. have been putting it off about 8 or nine months. Been getting by with 50/50 peroxide 2 or three times a week. 2 minutes each time. I take a 500miligram Tylenol about every 12 hours just to be safe. Never any pain. I also take a blood thinner. I have one other problem with Trigeminal Neuralgia that I am cautious about performing oral surgery. I plan on consultation. At any rate the peroxide I credit with getting by pretty well. Didn't mean to bore everyone.

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

Yes and please read the book the root canal coverup before getting one in your mouth. Wisdom before action.

More than one week after, no indication of infection I am happy to report. I will report in another month if I remain clear. I still face longer term dental work but at least I seem to have the infection in a managed state. Whether something lingers and again erupts, time will tell.
