what is the most common bacteria in the failed root canals? and what are the best ways to kill it?

It's a million-dollar question and answer!  There are currently a lot of researches on this subject.\n\nMost of the dentists currently agree that the is the most predominant bacteria in teeth with failed root canal therapy    is Enterococcus faecalis (gram negative, anaerobic).  This bacteria evolves and and is found to survive harsh conditions prevailing in the root canals of endodontically treated teeth.  Scientists believe that E. faecalis has the ability  to form calcified bio-film on root canal dentine.\n\nBesides physically cleaning the canal with the dental files, dentists use 2 main chemicals to treat or disinfect the root canal.  They are 17 percent ethylene-diamine-tetra-acetate (EDTA)and 2.5 percent sodium hypochlorite (NaOCl). Recently, laser is also recommended as another method for sterilizing the canal.\n\nBroad spectrum antibiotics such as tetracycline and clindamycine are also very effective in controlling infection surrounding the root canal (apical pathology). Occasionally, at the last resort of trying to save the tooth, apicoectomy and root amputation are necessary to get rid of these persistent bateria and infection.

It sounds like an infection.....although you have currently taken antibiotics you may need a different kind now....you may want to follow up with the dentist ASAP......\n\nI'm sorry you're in pain....good luck

This happened to me too my old shitty dentist didn't do a good job, she didn't drill and clean all the decay, now after few years i found a new great dentist, he fixed he said i may have ended up having root canal too, maybe tomorrow, maybe in five years maybe never as long as it doesn't hurt and since he filled my tooth again, he even put some medicine there it doesn't hurt and no problems whatsover! So find a good dentist that's a start! ask your family or friends i am sure somebody knows, that's how i found mine!

If you really enjoy root canals you will enjoy trying to fix a stick of RAM.  :-)\n\nIf you bought it from a reputable company like Crucial, Kingston, PNY, Kahlon, or even a chain store like Best Buy, Circuit City, etc, the RAM will have a lifetime warranty.  Just get it replaced and don't go through the pain and agony of that root canal...... er, I mean that RAM repair.

There is no way of preventing it from getting worse. You might be able to slow it down by flossing, brushing and mouthwash and not eating sugar. If you wait too long to go to the dentist you will have to get a root canal. Take it from me I have lots of experiences with cavities, unfortunately.

I've had quite a few  of these.  The main thing is to get the infection out.  They will sometimes lance it to drain it off sometimes they don't even do that... Just put you on an antibiotic for a little while.  If they aren't going to try to save the tooth, they will then pull it.  If there are going to save it they will do a root canal.  I had several a long long time ago.  At that time the dentist did not give me anything either.  His said I had to be able to feel it to tell him when it started hurting.  It was really bad.  However I have had a couple more in recent years.  I had a great dentist and he NEVER made me to thru it without novocaine.  Also he would give you laughing gas and it made the experience not bad at all.  (But then again I LOVE laughing gas)  You just don't seem to care what they are doing.  Unless this is your regular dentist I might want to find somebody else.  There is no sense in going thru it with pain  (It's painful enough when you find out how much all this is going to cost)  Quite a few years ago root canals were up to about 700 bux a shot.. they if you have to have a crown put on it that about another 700.  Hopefully you have good dental insurance.    Truly the worse part is of the unknown.  Most people just aren't overly fond of going to the dentist.  Good luck

A root canal treatment is "basically" the act of taking out the contents from the center of the root, all the way to the tippy end, and then sealing the hollow space with a filling material.  Many people say that they "had the root removed" from a tooth, but root canal treatment treats the CANAL in the center of the tooth.\n\nUsually, it is required when the tissue inside the center of the tooth (ie: in the root canal) is diseased or dead.  This is usually the result of an infection caused by tooth decay that has gone "all the way to the nerve."  The idea here is to eliminate the infection by removing the tissue.  The next goal is to smooth out the inside of the canal(s) so that a filling material can pass freely to the end of the tooth to seal it off.  Once it is sealed off, it is no longer a source of infection to your body.  Your natural immune system will continue to fight off any infection that may have entered the bone and eventually your body will heal.  Some people need antibiotics to help in this fight, but they are not always necessary.\n\nAny pain after the procedure is NOT from inside the tooth. It is from the swelling and infection in the bone at the end of the tooth. Taking the nerve out (or what remains of the nerve) is just done so that we can seal the end of the tooth so that the body can heal the damage in the bone. This takes a while. Root canal treatment is not a magic wand that instantly makes you feel better. It is just the first step in what will then allow your body to heal. The healing can take a while, especially if you had a good sized abscess on the tooth. \n\nIn back teeth, it is generally recommended to have a crown placed over the tooth to protect it from breaking, as teeth that have had root canal treatment tend to dry out somewhat and become more brittle and susceptible to breaking.  Front teeth are often strong enough to go without a crown, but sometimes they need a crown, too.\n\nYeah, it can hurt, maybe 1 out of 10 times.  That 1 guy where it hurts probably waited until the tooth was already really killing him before he went for treatment.  I tell my patients that root canal treatments are like teenagers.  9 out of 10 are no problem at all, but you always hear about the bad ones.\n\nGo here and click on the link about root canal treatment:\n\nhttp://www.ada.org/public/games/animation/interface.asp

This science project, linked below, hypothesized that Listerine Antiseptic Mouthwash would kill the most alpha streptococcus. \n\nThey based that hypothesis on what Marie Clark, Microbiologist at Memorial Hospital, said: "Listerene as an antiseptic should be the best at inhibiting alpha streptococcus."  They also based it on the fact that it was approved by the American Dental Association (ADA).

Sounds like the Root canal failed and the tooth died.  A dead tooth should not be left alone or crowned.  It should be extracted and replaced by an implant.

Do you have a filling in the tooth in question? If you do, it is more that likely that the tooth started decay below the existing filling. This happens because when the dentist told you that the filling should be replaced, you didn't do it. \n\nI know this because it just happened to me. I ended up breaking the tooth, and because of the substantial amount of decay that the tooth had to be pulled. \n\nGet it taken care of soon. If the tooth doesn't hurt now, it will soon. Based on my experience, I am going out on a limb to tell you this, but you will probably need a root canal.\n\nTo answer your question, this is not something that can be treated naturally. The only thing that will be used that could be natural are the anesthetic for the extraction, and the post-op pain medications and maybe antibiotics.\nGood luck.

If the Apicoectomy was INDEED the last resort to save a root canaled tooth then I believe there is no better alternative other than to extract the diseased tooth and either place a dental implant or a bridge.  An apicoectomy is done if the root canal performed on the said tooth is failing and only amputation can preserve the rest of the integrity of the tooth.  \n\nOne thing though, there are different bone fillers after the apicoectomy renders the adjacent bone hollow.  You may want to ask your general dentist or your periodontist about it.

One word: infection.\n\nA root canal treatment is aimed at cleaning and sealing one's tooth so the space filled by the infected nerve is devoid of infectious and inflammatory process. The nerve is then replaced by an inert material that won't cause inflammation and provide a good seal against infiltrations. Sometimes, bacteria can stay in some areas of the root impossible to clean, even for the best dentist in the world. It's often due to the shape of your root canal, and not because of your dentist.\n\nIn theses cases, treatments exist and can be discussed with your dental professional.

Ignore the "person" who is so positive that the tooth will turn black & die. It's already dead. It WILL turn black if you don't do the root canal.\n\nAsk the dentist to warm the anesthetic in warm water before he uses injects. You keep breathing S-L-O-W deep breaths - it really does help keep the pinch down.

1. Sodium hypochlorite (bleach) to kill the bacteria and dissolve tissue remnants.\n2. EDTA (ethylenediamine tetra-acetic acid) is used to soften the canal walls and remove the smear layer.\nI prefer to start with EDTA and finish with bleach, alternating as I go. Some people only use bleach.\nDon't use hydrogen peroxide. If it bubbles past the apex, you will get a very sore patient.

Yes of course, trust the Dentist, he knows what he's doing\n\nYes I've heard of the abscess it, it's like a kind of infection of a bacteria or something AND yes! it might spread to the other teeth if it is not pulled out...thank the dentist he did that...think where you'll be with that abscess still in your mouth\n\nhowever, that was not the only choice(pull the tooth out), certainly he could have given you a treatment of antibiotics to avoid the pain and make it less worst, but eventually you'd need a surgery(realted with the root canal)to get rid of that abscess

If you have a problem with your tooth, it can very easily manifest itself as a headache, especially behind/around your eyes.  You should call the dentist and have the date moved up/closer so you can get it taken care of immediately.  A person should only be on antibiotics for 7 to 14 days.  After that, the bacteria become resistant to the medication, and this could very well be what has happened.  The bacteria that caused the abscess have most likely become resistant and are now migrating to other parts of you body.  Have the date moved closer, and also have your dentist put you on a more potent antibiotic.

The nerve inside has died.  Bacteria are growing on the inside and dying, this is the gray, which will go more black.\n\nI had this on one of my front teeth. The tooth is fine, and shouldn't fall out.  You can get it whitened back up. They scratch of the back of the tooth, clean it up, then put a material on to cover the hole.
