How to Use Hydrogen Peroxide for a Tooth Abscess

| Modified: Oct 29, 2018
Hydrogen peroxide is an inexpensive natural remedy for a tooth abscess. Hydrogen peroxide is made up of hydrogen and oxygen. It has antiseptic and antibacterial properties. The brown bottle of 3% hydrogen peroxide from the drugstore or pharmacy is ideal for treating an abscess. Never use full strength food grade hydrogen peroxide internally or externally.

Mix 1 tablespoon of your 3% hydrogen peroxide with 1 tablespoon of water. Use this diluted solution to hold and swish in your mouth for 2 minutes. Spit the solution out and rinse your mouth. Repeat the hydrogen peroxide swish every 2 hours during the day and again if you wake up in the night feeling pain.

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.

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. :)

Sarah, if you can get clay, apply it. First thing, it calms the pain. Then, it can help pull out the abscess.

Alpha lipoic acid stops nerve pain ....then topical activated charcoal~in the mouth could absorb the toxins...and castor oil on the face over the tooth pain will penetrate and heal the throbbing pain. I know these ones first hand. Blessings, charity

How long did it take for it to completely go away?

Buy some chili powder ( strong kind, like Indian chili powder) put a bit on your finger and apply to affected area, it essentially anesthetizes the pain area with small burning sensation. Turmeric mixed with pepper or also ginger root should be second choices.

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.

Thank yu so much for your review! The literal exact same thing happens to me, cracked in half and everything and I didn't know if I could use peroxide but after reading your review I know I can, again thanks again (:!

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.

hi, is the 'tablespoon of Peroxide' = 35% peroxide or 3% peroxide?


EC: 3%!!

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 have been using HP for about 2 months. Oral surgery was the recommendation. Have L. molars 20 &21., one broken at the gum line that can't be repaired. I have been staving off the tooth extraction as long as possible. I take a blood thinner so surgery is the option. Not looking forward to implants either. I have been wondering how often is safe to use HP. Someone here I think said twice a week was OK. If anyone else has a routine, I would sure like to hear. I have been doing pretty well by being careful with foods with hard surfaces. I also take a Tylenol 500 mg twice a day in case of a flare up. But haven't needed anything for pain otherwise.

I just wanted to add how grateful I am for all the help others have provided. Have been reading post from years ago and there is a lot experience available. Thanks Earth Clinic.

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.

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.

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

BillyBones, I am hoping you still have this article on your system. Id like to know how your teeth are doing today, 2 years later. I have a dentist that wants a tooth pulled and I am freaking out. The amoxicillin worked, and I am using hp swishes and everything is getting better, but afraid what is lurking at the root. Hope you get this to let me know how you're teeth are now doing. thanks

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!

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 :)

So far so good. I just used a capful of the 3% hydrogen peroxide literally just five minutes ago, for the first time. Too soon for a final verdict, of course, but the tooth/gum pain seems to be reduced (not entirely gone). I did a capful of the 3% HP, without mixing it with water as a 50/50 mix, swished it around the (presumably) infected area for 30 seconds, then spit it out, then repeated once, then rinsed my mouth with water. My dentist can't see me for two weeks so I need to bridge the gap between now and then. I'm hoping the pain stays under control for a bit. 4 stars for now, will re-rate after a few hours.

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.

Replied by Bobbie

HP gets rid of infection temporarily but will come back, you are playing with fire not taking the antibiotics. You will need the root canal. When it comes back if the puss gets in your blood can cause gangri and is life threatening. Please take your antibiotics and get the root canal.

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

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.

It is 2 am. My husband, who has had tooth pain for 2 days now, woke me at 12:45 howling in pain and using unprintable words. After googling emergency dentists to call in the morning, I came here to EarthClinic and found out about gargling with 50/50 hydrogen peroxide and water.

Within 3 or 4 minutes he was smiling... but it was short-lived. So I hauled him back out to the kitchen sink for a repeat... but this time he's doing it with just the peroxide, no water.

I'm gonna' call it 'better but not cured.'

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!

I couldn't agree more! In fact, just a week or so ago I wrote a post making almost the exact same recommendations that you did, except for the saltwater rinses, which I agree are a good idea as well.

All hail GARLIC! It has so many beneficial uses. It's something that everyone has access to, and costs pennies per 'treatment'. It's also great for stopping a cold in its tracks if you load-up on it the moment you feel like you're coming down with something.

Nothing is better than the real thing, though. The garlic capsules aren't as effective when treating colds, etc. I also read recently in a consumer report that three different brands of garlic capsules/pearls tested contained only 3% garlic! Plus, they cost a whole lot more.

Why pay $15-20 for a bottle of pearls to get only 3% of the benefits, when for a two bucks, you can get 2-3 entire *heads* of the real thing with 100% potency?
