Just to let people know that I got a condition known as hairy tongue about a year ago when I first started messing about with H202. If you are going to use it for a mouth wash, make sure that even the 3% Peroxide is diluted. At most, the ratio is supposed to be 1:5 in the water.

Anyway, I took it straight and it caused a horrible unsightly condition called hairy tongue which I have NOT been able to get rid of.
I have posted something on this site about six months ago - tried everything, salt water, h202 dilute, lemon water, brushing it with a scraper etc and NOTHING works.

I am not knowing Hydrogen Peroxide. I am sure it is good stuff and has its uses but don't use it as a mouthwash like I did without diluting it. Be careful when experimenting.

Take Care (and if anyone knows something that can help me, please let me know)

I use hydrogen peroxide to rinse my mouth out after brushing and flossing in the morning....but I absolutely dilute it. About 1/2 & 1/2 should be fine. Not sure what to tell you about the hairy tongue though...sounds like it must be awful though. I'm sorry you had to experience that.

I suffered from a "hairy tongue" or a white coated tongue for many months. I did not know what caused the problem, and tried every oral hygiene method I could think of to remedy it, but to no avail. Everyone to include the doctors said it was because I had a dirty mouth. I have always prided myself on taking care of my dental needs so I knew a dirty mouth was not the problem. To make a long story short, through my persistent, I finally found a doctor who diagnosed the problem. The hairy tongue was caused by excessive yeast in my body. Just as excessive yeast can show up as a vaginal yeast infection, it can also show up as a hairy or white coated tongue in the mouth. The doctor prescribed the proper antibiotics and within days the problem disappeared.

Hyrdrogen peroxide is found in pharmacies but you gotta make sure it's very distilled when mixed with water, cause H2O2 is very powerful and damaging, so first make sure it's at a safe concentration before consuming, as for the exact concentrations I wouldn't be the right person to ask as I don't use it- previous posts give exact concentration details, hope it works out!

I drink alot of coffee with milk and always thought it was the milk that caused the BB. I just did the peroxide gargle and what a difference. It's like someone took the sweater out of my throat. I'm very grateful for this advice and will share with others. Thanks you.

I used to have a somewhat furry tongue(white) I used to smoke for years and drank a lot of beer. What I did was I went out and bought some extra virgin coconut oil, originally to make the swelling in my tonsils go down. I brushed my teeth first and then put a big glob of oil in my mouth. I tilted my head back and let it sink to the back of my throat. I held it there and gargled it for about 20 minutes. When I spit it out, my tongue was immediately wayyy pinker. I think I'm allergic to the oil though, because I ate a few tbsp of it and broke out in minor hives on my finger and lips. But it really cured my white tongue. I stopped using it though because of the hives and now to keep my tongue pink, I dip my toothbrush in mouthwash, brush my tongue, and use a tongue scraper to scrape it all off gently. My tongue has improved 90% in one week.

I have been suffering from bad breath for a few years now and had tried various different remedies, some worked, but mainly for a very short space of time, the bad breath always returning. I tried the HP and am very pleased to say my bad breath has COMPLETELY cleared up! I used 2 parts HP to 5 parts water of 3%, 10vol type (that is what is says on the bottle!). I gargle and rinse morning and night, for as long as I can stand, usually max 30 secs per mouthful, then spit out. I then rinse my mouth with salt water. I also wait the 15 mins before I drink or eat anything.

With other remedies and mouthwashes, they simply mask the problem, but with HP because it eliminates the actual bacteria, you then eliminate the bad breath. A big THANK you to this site for helping me in this way, I feel so much better all round. I would definately urge ANYONE with bad breath problems to give this a go.

I am encouraged by the information on this site as I have suffered from CHRONIC bad breath for over 10 years now. I am almost afraid to put too much hope into the hydrogen peroxide remedy as everything else I have tried has ultimately failed over time. I have had some success with commercial remedies, however, this is always short lived - it is as though my mouth becomes accustomed to the active ingredients and the effectiveness wears off. I would be interested in hearing if people with CHRONIC bad breath have had long term success using hydrogen peroxide. Many thanks!

Hi all... I've had severe halitosis for over 24 years, it's such a crippling and alienating condition to suffer from, like everyone with this ailment, I've suffered my fair share of humiliation and embarrassment, and because of it I've tried effortlessly to find a cure by seeking answers from many 7 dentists, 4 ENTs, 3 Gastroenterologists and over 20 GPs and the list goes on and none were able to help me or even pinpoint the cause of it, they were all puzzled and basically gave up! Tried all the mouthwashes and expensive treatments out there, went on various diets and detoxes, tried endless antibiotics but with no avail!

I tried Hydrogen Peroxide and ACV 3 years ago when I stumbled on this website and guess what? It actually worked! But only temporarily!! The bad breath didn't completely diminish but it improved by probably 90% so at that time I was probably the happiest person on earth because I truly believed that I was finally being cured and that in few more days or weeks the bb will completely disappear! But to my disappointed the bb never really disappeared but instead it came back and neither HP nor ACV worked on me again. It's like the bacteria in my mouth or gut - or wherever it's hiding - had become immune to it. So I was so disappointed and my hopes and dreams were shattered once again!

What I want to know from all of the people who have tried HP and ACV and had positive results with it, whether their cure was short term or they were actually completely cured and bb never returned?

I would also appreciate any suggestions or other cures that might help me with my condition as it's ruining my life.


Yes, I had the same experience. Hydrogen peroxide + baking soda worked fabulously for a while. Then they didn't. I have found the only toothpaste that is remotely effective (although I still have bb) are the Eco Dent powder toothpastes. I like anise and cinnamon. Anything else on this planet doesn't work.

I am going to try drinking diatomaceous earth. Also attack the yeast issue I have.

I know a lady that was complaining about really bad breath. She found out that she had the Helicobacter Pylori bacteria in her stomach. Once she got read of it, the bad breath dissapeared. Look into Manuka honey, Grapefruit Seed extract, garlic. Clean you blood with stinging nettle tee.

3 steps to help conquer the battle of the breath, and each solves a contributing factor, so try them separately for 1-2 weeks at a time, or all together, whichever you prefer.

1. Add baking soda to your toothbrush and oral rinse. It neutralizes acid like no tomorrow. Tastes blech, works great. Avoid alcohol mouthwashes.

2. Consume yogurt daily, or a similar dose of probiotic drink or capsules - yogurt is best. Look for at least 4 billion probiotic per serving.

3. Scrape your tongue with a spoon daily.

Also, Check your pH for acidosis. When your pH is in balance, your GI tract and breath will be also. And make sure you are getting enough water.

Desperation and embarrassment let me to searching. I don't know where my father got his information from but for years now I have heard him talking about peroxide as an effective rinse for bad breath. I really did not pay much attention to him even though I'm a nurse and I use peroxide all the time as antibacterial.

This afternoon I was sitting and talking to a few colleagues and the one I was closer to started saying "what is that smell, it smells like a dead rat in here". Having had bad breath for years I immidiately got suspicious. It's like when people sitting next to you all of sudden start fidgeting and looking around and you know next out comes the gum they offer you. Anyone with bad breath history know what I'm talking about. So I looked in her direction and continued talking and she repeated the same thing. Anyway I finshes my talking a little sooner than I wanted to and left together with one other colleague. I went back in and noticed one turned her head away when she saw me and the same colleague was just finishing the same humiliating sentence that she had said before.

I tried to convince myself to give her permission to make me feel bad but she won. I was devastated. I then decided to start looking into peroxide as a mouthwash and I stumbled accross this site.

I have used several different mouthwashes over the years Some were somewhat effective. I never really kept using them for a long time for I'm afraid that long term use of them may cause cancer. This morning, several hours before my humiliation, I used Tom of Maines because it claims to be natural. I have no choice now but to use peroxide and I will definitely do try it and I hope my halitosis and my days of bad humiliation are OVER.

So sorry you experienced that rejection but happy you have found the earth clinic family. If we say something thoughtless or stupid at times. Please forgive us . My worst breath experience was during a time my dentist put me in a situation where I had to keep returning trying to get them to do the right thing. They didn't, so I had to get a mediator. Well that stress made my normally lovely breath, turn horrible. I was shocked my breath was so awful. I use coconut oil, pull it through my mouth for five minutes in the morning. At bedtime I eat a charcoal tablet to clean up my gut. Hope you find your sweet breath again. Forgive them for they know not what they do. What the enemy means to harm us, is worked out for our good. Amen

It is my opinion that bad breath comes from the stomach. Be sure you are balancing your meals with many veggies and fruits, less starch. Consider reading Candida: Killing Me Sweetly. It's helped my husband.

I use over the counter 3% hydrogen peroxide as a mouthwash, but have always disliked the aftertaste. I purchased a bottle of peppermint oil from the baking section of my local market, and put one tablespoon in an eight ounce bottle of 3% hydrogen peroxide. Mouth feels very clean (and now minty fresh, too!) Others may like to add their favorite flavors, increasing or decreasing the measurement according to taste. Make sure to GENTLY shake your bottle before opening to keep peppermint oil evenly distributed, and keep your mouthwash in an opaque bottle (I use the same brown bottle purchased at the dollar store). Refrigerate if your bathroom is very warm, and keep bottle out of direct sunlight.

I just bought the peppermint oil - great suggestion - it is much better this way but I dilute mine with 50 % water. Do you use hydrogen peroxide 3% straight?

Hi, just wanted to share with you my cure for an infected gum -- hydrogen peroxide. Also wanted to respond to Subashini from Kuwait, because I may have an answer for her about the bad breath and oil pulling.

My story (I'll try to be brief)... got a piece of food stuck in the gum behind one of my front teeth. No matter what I did -- floss, oil pull, swish peroxide -- it didn't come out. I then went to a new dentist last week to have my teeth cleaned and the stuck particle removed. Lucky me -- the hygenist was just filling in for the day and during the teeth cleaning part, said she saw something dislodge but then "lost sight of it". Okay, fine, I thought. That night I awoke in the middle of the night with terrible bad breath. It was so bad it actually woke me up. Yes, I do have sensitive smell!! When I looked at the right front tooth the next day, I noticed that the gum was severely swollen, from the tooth to the roof of the mouth. The bad breath also persisted. I started my holistic regime of oil pulling, then later swishing with hydrogen peroxide. The oil pulling, like Subashini said, made my breath worse. YUCK! I tried swishing with sea salt. No luck. Finally I had the idea a couple of days ago to soak a cotton ball with hydrogen peroxide and then hold it (tightly) to the swollen gum for 10 minutes. I also pinched another h202 soaked cotton ball to the back side of the tooth where the piece of food had initially lodged. Interestingly, it didn't hurt, but certain areas of the gum turned white. 10 minutes later the white had disappeared. Glad to say that my bad breath smell immediately disappeared and has not returned. My gum is looking a little better. A couple more days of this (soaked h202 2x a day) and I think I will be back to 100%. I highly suggest this technique if you have a tooth abcess or swollen gums from an infection. It is the best way for hydrogen to penetrate, otherwise it just turns to foam if you swish it around in your mouth.

So Subashini, I think your issue may be an infection somewhere in your gums that the oil pulling is bringing to the surface. Infection smells like dental plaque -- quite disgusting. My suggestion is to pull up your top lip (then pull down the bottom lip) in the mirror in daylight and look for redness in your gums. If you can pinpoint an area, then soak it with hydrogen peroxide cotton ball 2x a day for a day or two. I would predict that your issue of bad breath will immediately go away, even after you oil pull.

Oh, one more thing. You will need to bend over a sink whilst holding the cotton ball to your gums and let your saliva run out. You may need to do round 2 during the same session. Most importantly, you don't want to swallow anything! Rinse well afterwards. Hope this helps someone, somewhere. All My Best,

A science teacher recommended this to me years ago and I've been doing it ever since. Hydrogen Peroxide is a great mouthwash. It kills the bacteria in your mouth which the cause of bad breath. Also brightens your teeth a bit. I take a swig of 3%, swirl it around my mouth for a min or so, spit it out and wallah, breath is fresh.

Oil pulling with one tablespoon of sesame oil, coconut oil , or rice bran oil. swish and pull one tablespoon of oil for 15-20 min. and spit out the oil. It should be a whiteish foam after 15-20 min of pulling.

This will help with all kinds of infections. It will help dotoxify the entire body.

Have you ever known somebody with bad breath? Here is the cure.

1-Do gargles with hydrogen peroxide. All the bacteria accumulated by years will be killed and your breath will be as fresh as it can be.

2-Do the same once a week or maybe once a month. If you still have any problem, that I doubt it, probiotics will be the solution for getting rid of bad breath if it is accompanied by body odor.

But the first step is the gargles.

I've used hydrogen peroxide, 3% pharmacy grade cut 50% with water, to rinse my mouth before brushing, which has been a great help with eliminating bad breath and plaque. But here's a remedy that no one may have thought - a treatment for "tinea cruris" commonly known as jock itch. I had an issue with this for several months and during this period, several times a week, I used Curex and other over-the-counter options to eliminate it, spending $20.00 to $30.00 to no avail. I knew hydrogen peroxide was effective in killing bacteria, so, as a last resort, I cut the pharamcy 3% grade 50%, just like the mouth wash, and used it-in 2 days!!! the itch and soreness was gone! No joke. Total cost 20 cents!

I have always used natural remedies to cure my ills or take care of my skin, and when a cousin of mine became ill with liver cancer I started searching the internet frantically (that's how I came across this site) for a way to help him get rid of the toxins in his body, but it was too far gone. He died one month after being diagnosed with the cancer. A few months ago I started dating a gentleman, who is a great guy but he had bad breath, he brushed and gargled Listerine which didn't help, but masked the bad breath for a few minutes. Since it was his breath, and not his personality that was bad, I bought a bottle of hydrogen peroxide for him to brush his teeth and tongue with and also gargle. The next time we went out the bad breath was gone and he said he can tell the difference. I don't know what he had or what happened scientifically but the hydrogen peroxide worked.

I started using hydrogen peroxide as a mouth rinse 1/2 peroxide 1/2 water....Rinse mouth with the solution and let stand for 2-3 mins, if you look into your mouth you can see the peroxide solution working in between teeth and under the gum line. rinse well after 2-3 min and brush teeth as usual. If you use this solution at night you will notice a lack of morning breath in the am.....The peroxide kills the bacteria that causes bad breath....last but not least...peroxide is cheap!!

3% hydrogen peroxide cures halitosis, instantly. Excellent remedy for halitosis or sulphur smell when some one sneezes. This is not the masking agent like mouth freshener but it takes care of the problem and whitens the teeth.

I have battled bad breath ever since I gave birth to my first born three years ago. When I had my second child, the smell got even worse. Almost smelled like a "toot"/fart, whatever, it was gross. I tried everything, but THE ONLY thing that has worked for me is gargling w/ hydrogen peroxide. I bought the regular 3% from the drug store and gargle w/ it in the mornings and evenings. The taste is gross, and it leaves a film in your mouth that takes about 5 minutes to disappear, but it's well worth it. After I gargle (20-30 secs. is all I can stand) I immediately use a tongue scraper 5 or 6 times. Make sure you scrape as far back on your tongue as you can and don't eat or drink for 15 minutes afterwards. It's cool b/c once you start to gargle, you can actually feel the hydrogen tingling on your tongue like it's fighting the bacteria. As an added bonus, my teeth are whiter, and my gums and tongue are a healthy pink color. I love this stuff, and at $.99 cents for a bottle, how can you go wrong?!

Carey, about the taste - go to a local health food store or market and ask for a bottle of peppermint oil (spearmint and vanilla work too) and add a 1 tablespoon in an 8 ounce bottle of peroxide 3% for minty taste (no sugar so it won't be sweet) but it won't have that awful peroxide taste either. Leaves you mouth minty fresh.

Also, Dee, Dilute 1/2 water and 1/2 peroxide. I use two capfuls of HP and two capfuls of water. FYI

Correction: regarding amount of peppermint oil used in HP. Originally, i said 1 tsp for 8 oz bottle - not what I meant this was TOO much peppermint and too HOT! (Felt like it burned my tongue!) Try using only 1/4th (few drops) tsp per 8 oz then add more as you adjust to it.

I started putting HP on my tongue and letting it sit there without swallowing it for 5 minutes. (before I put the HP on i brushed and flossed my teeth first thing in the morning). After the five minutes were up, my tongue was thick and gooey with bacteria. After that I scraped my tongue with a spoon. It was gross but my gums no longer bled when I brush them and also my energy levels are up!

After reading that Hydrogen peroxide kills breath odor. I decided to do some reasearch before I tried it. What I was basically trying to find was information that would convince me that peroxide wasn't going to poison me. Well I was convinced and decided to try. I've been rinsing my mouth with diluted 3% hydrogen peroxide for the past 3 days and it worked...I had horrible bad breath it was horrible but now it's gone. I'm even having my boyfriend do the same. I'm so happy I tried this. I highly recommend it!!!!!

I had a problem of Bad breath for many years now. I had mints all over the place to make sure I had them all the time. I brushed my teeth after every meal and yet within an hour the bad breath was back. Then I came across Sharon's advice last week. Tried it and it WORKED!!! No bad breath from then on. Amazing! I rinsed my mouth in ordinary peroxide for about 2 minutes. Yes, my tongue was a bit sore. I rinsed after lunch and didn't have dinner-- I wasn't hungry, just so very happy. Next day my tongue was back to normal. Thank you very much, Sharon! It has changed my life. A question: Do you think it is okay to have a quick peroxide rinse everyday morning? Does it harm the teeth enamel in any way?

EC: We read somewhere on the internet a few months ago that hydrogen peroxide can potentially wear down dental fillings, but is fine for dental enamel (it's what they use in teeth whitening formulas). We rinse with it every few days and have NOT noticed any fillings deteriorate!

I don't know how else to post on this thread so I am sub posting. I developed bad breath right around 18 when I started eating meat again. I've been to many dentists all who said I have PERFECT teeth. Well Ive tried so many things and the only thing that is working now is lemon juice in my water bottle. I add about 1 tbsp to a normal sized water bottle and I have one daily. Another person I know is successfully using digestive enzymes also. I can attribute my bad breath to my diet but I don't know what specifically is causing it. Even though this is helping I still don't know what is the root cause for my BB.
