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. :)

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 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.

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.

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.'

I had a tooth /gum infection of an upper jaw molar (not the back one) that caused swelling on the left side of my face up to my eye including swelling the eye partially shut. I got prescriptions for antibiotics which brought the swelling down but still left what appears to be a bump abscess on my gum which would cause the tooth to become sore also.

The antibiotics clearly were not working to get rid of the abscess, so earlier today I tried injecting 3% hydrogen peroxide (no stabilizer) at several locations in the gum (2-5ml) in and around the abscess. Warning - doing this will really hurt like hell when actually injecting the hydrogen peroxide, especially the first few injections when the hydrogen peroxide is actually killing the infection under the gum but it seems to have removed almost all the abscess infection - there is little or no soreness from it now - however the area is somewhat sore from all the syringe pokes as I type - I'll have a better idea tomorrow if the infection is completely cleared up when the gum heals some but it's feeling much better already.

I don't know if injecting hydrogen peroxide is 'safe' so I can't recommend it for others, but it definitely seems to have the potential to stop at least some abscesses.
