In the photo to the right you can see a common presentation of an infected tooth.&nbsp; In this case, an old root canal that has failed is draining pus and infection from the tooth.&nbsp; As the picture shows, the drainage presents as a pimple on the surface of the gums on the outside surface of the tooth.<\/p>\n<p>Over the years I have observed that when a root canals fails, it can usually be attributed to one of the 5 reasons listed below:<\/p>\n<ul>\n<li>Overfilling the tooth with the filling material<\/li>\n<li>Incomplete filling of the canals of the teeth<\/li>\n<li>Cracked or fractured roots<\/li>\n<li>Setting the bite of the tooth too high afterward<\/li>\n<li>The patient is immune compromised, has an auto-immune disease, or has Multiple Chemical Sensitivity (MCS)<\/li>\n<\/ul>\n<p>In blog posts to follow, I will be discussing these factors separately.&nbsp; I will include case studies and photos to show how and why these problems occur.&nbsp; No matter what the cause of the problem or failure, the result is usually the same.&nbsp; When a root canal fails, the consequence is almost always more infection.&nbsp; This does not always result in pain, however.<\/p>\n<h2>If my tooth is infected shouldn&#8217;t it hurt?<\/h2>\n<p>You would think that if a previously done root canal becomes infected it should cause pain, right?&nbsp; Not necessarily.&nbsp; Think about it for a moment.&nbsp; During a root canal procedure, the nerve is totally removed from the tooth.&nbsp; So, if there is bacteria left behind or if the tooth becomes re-infected later on, how would you feel it?&nbsp; There is no more nerve there to tell you there is a problem or let you know that pressure is building up again from the infection.<\/p>\n<p>An infection can remain for years until something upsets the balance because it is embedded in the jaw,&nbsp;which is hard bone, as it drains from your tooth, .&nbsp; So essentially, the infection is locked in the jaw bone until it increases enough and the pressure builds up enough for it to push its way out into the gums around the tooth.&nbsp; Basically, the pressure builds up until it finds an avenue to push its way out.<\/p>\n<h2>Are Root Canal Filling Materials Toxic?<\/h2>\n<p>In this case study we are going to examine what can happen when the dentist overfills the canals, and the filling material extends beyond the end or apex of the tooth.&nbsp; Often when this happens it does not mean failure.&nbsp; The body adapts and can still heal.&nbsp; However, whenever there is filling material or cement that is pushed outside the tooth,&nbsp;inflammation is always created, along with the potential for further problems.&nbsp; These problems may include:<\/p>\n<ul>\n<li>Temporary pain that usually resolves in a few weeks<\/li>\n<li>Long term soreness that usually resolves but not always<\/li>\n<li>Long term inflammation and low grade infection<\/li>\n<\/ul>\n<h2>Root Canal Failure: Case Study #1<\/h2>\n<p><a href=\"https:\/\/myholisticdentist.com\/wp-content\/uploads\/2018\/01\/Xray-of-Overfill-and-Infection-16.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3539 size-medium alignright\" src=\"https:\/\/myholisticdentist.com\/wp-content\/uploads\/2018\/01\/Xray-of-Overfill-and-Infection-16-300x186.jpg\" alt=\"Failed Root Canal\" width=\"300\" height=\"186\" srcset=\"https:\/\/myholisticdentist.com\/wp-content\/uploads\/2018\/01\/Xray-of-Overfill-and-Infection-16-300x186.jpg 300w, https:\/\/myholisticdentist.com\/wp-content\/uploads\/2018\/01\/Xray-of-Overfill-and-Infection-16-610x379.jpg 610w, https:\/\/myholisticdentist.com\/wp-content\/uploads\/2018\/01\/Xray-of-Overfill-and-Infection-16.jpg 680w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a>This patient presented with this infected root canal draining pus out to the gums, as shown in the featured picture above.&nbsp; There was some discomfort but no significant pain.&nbsp; The image taken of the tooth showed that there was a slight overfill, but most dentists would say that this is acceptable and that the root canal would still be considered a success.<\/p>\n<p>However, this is by no means guaranteed.&nbsp; Some patients react to the materials used to fill the tooth during a root canal procedure.&nbsp; One of these materials is called gutta percha, which is similar to latex from the gum tree. The other is a sealer.&nbsp; Sealers can sometimes cause inflammation in the tissue around the tooth, depending on which type is used.<\/p>\n<p>Even though the Xray looks acceptable, the situation was not, as the tooth was clearly draining infection and had to be treated.&nbsp; The patient was given the option of seeing a specialist (endodontist) to re-treat the root canal, or extract the tooth.&nbsp; The patient chose to extract the tooth and replace it with an implant later.<\/p>\n<p>After the extraction was done, the infected tissue was removed from the bone so that bacteria would not remain and infect the healing site.&nbsp; In holistic or biological dentistry this is called a cavitation.<\/p>\n<p><a href=\"https:\/\/myholisticdentist.com\/wp-content\/uploads\/2018\/01\/Overfill-of-Root-Canal-Final.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-3547 size-medium\" src=\"https:\/\/myholisticdentist.com\/wp-content\/uploads\/2018\/01\/Overfill-of-Root-Canal-Final-300x265.jpg\" alt=\"Gutta Percha Overfill\" width=\"300\" height=\"265\" srcset=\"https:\/\/myholisticdentist.com\/wp-content\/uploads\/2018\/01\/Overfill-of-Root-Canal-Final-300x265.jpg 300w, https:\/\/myholisticdentist.com\/wp-content\/uploads\/2018\/01\/Overfill-of-Root-Canal-Final.jpg 477w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a>After the extraction I was able to capture the root canal overfill in this photo.&nbsp; The gutta percha was pushed outside of the tooth during the filling procedure, and the overfill is very clearly outside the tooth.&nbsp; This created inflammation and eventually infection,&nbsp; resulting in the pus draining out to the gums as recorded in the first photo.&nbsp; You can also see the evidence of a small cyst attached to the end of the root.<\/p>\n<p>This is a clear example of what can happen with root canal teeth, and this type of problem is not always picked up by Xrays.&nbsp; Sometimes you need a special type of imaging to see what is really going on.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What causes existing root canals to become infected and fail?&nbsp; In the photo to the right you can see a common presentation of an infected tooth.&nbsp; In this case, an old root canal that has failed is draining pus and infection from the tooth.&nbsp; As the picture shows, the drainage presents as a pimple on [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":3549,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","om_disable_all_campaigns":false,"footnotes":""},"categories":[165,268],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What Causes Root Canal Infections and Failure? - Integrative Dentistry, San Diego Holistic Dentist<\/title>\n<meta name=\"description\" content=\"Can old root canals fail?

He began his career by owning and operating a network of six offices in the San Francisco Bay Area.\u00a0 Presently he owns a private holistic practice in North County San Diego\u2019s Encinitas. Dr. O started looking for solutions to his health challenges that resulted from the stress and environmental toxicity that built up over a ten year period running his dental network. He has dedicated himself to learning about oral systemic problems and how dentistry can affect your health. He has applied what he has learned over the last twenty years to ensure he, his staff and his patients are protected from the chemicals and toxic materials found in most dental offices. He has produced an environmentally friendly office that is also peaceful and calm. He is an expert on dental materials having looked at hundreds of biocompatibility lab tests over the years.\u00a0 He has identified the most bio-friendly materials to use in his practice and which dental materials can be used to replace metal fillings and crowns, including BPA free and fluoride free \u2018white\u2019 fillings.\u00a0 He also uses metal-free Zirconia or ceramic implants and PRF (platelet-rich fibrin) grafting materials which come from the patient\u2019s own blood. Dr. O\u2019Rielly teaches C.E. courses on the systemic effects of gum disease.\u00a0 He is an expert in using phase contrast microscopy for analyzing dental infections, where he shows patients what kind of microbes, i.e. bacteria, amoeba, and yeasts like candida are populating the mouth and affecting the body as a whole. He has an educational blog and is writing a book on dental health called \u2018Hidden Dental Infections: Healing Root Canals and Infected Teeth with the Erbium Laser\u2019 where he discusses dental nutrition, toxic dental materials and the effects of old root canals on inflammation and overall health.\",\"sameAs\":[\"https:\/\/myholisticdentist.com\",\"https:\/\/www.facebook.com\/holisticdds1\/\",\"https:\/\/twitter.com\/https:\/\/twitter.com\/holisticdds\"]}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"What Causes Root Canal Infections and Failure? - Integrative Dentistry, San Diego Holistic Dentist","description":"Can old root canals fail?

He began his career by owning and operating a network of six offices in the San Francisco Bay Area.\u00a0 Presently he owns a private holistic practice in North County San Diego\u2019s Encinitas. Dr. O started looking for solutions to his health challenges that resulted from the stress and environmental toxicity that built up over a ten year period running his dental network. He has dedicated himself to learning about oral systemic problems and how dentistry can affect your health. He has applied what he has learned over the last twenty years to ensure he, his staff and his patients are protected from the chemicals and toxic materials found in most dental offices. He has produced an environmentally friendly office that is also peaceful and calm. He is an expert on dental materials having looked at hundreds of biocompatibility lab tests over the years.\u00a0 He has identified the most bio-friendly materials to use in his practice and which dental materials can be used to replace metal fillings and crowns, including BPA free and fluoride free \u2018white\u2019 fillings.\u00a0 He also uses metal-free Zirconia or ceramic implants and PRF (platelet-rich fibrin) grafting materials which come from the patient\u2019s own blood. Dr. O\u2019Rielly teaches C.E. courses on the systemic effects of gum disease.\u00a0 He is an expert in using phase contrast microscopy for analyzing dental infections, where he shows patients what kind of microbes, i.e. bacteria, amoeba, and yeasts like candida are populating the mouth and affecting the body as a whole. He has an educational blog and is writing a book on dental health called \u2018Hidden Dental Infections: Healing Root Canals and Infected Teeth with the Erbium Laser\u2019 where he discusses dental nutrition, toxic dental materials and the effects of old root canals on inflammation and overall health.","sameAs":["https:\/\/myholisticdentist.com","https:\/\/www.facebook.com\/holisticdds1\/","https:\/\/twitter.com\/https:\/\/twitter.com\/holisticdds"]}]}},"_links":{"self":[{"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/posts\/3493"}],"collection":[{"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/comments?post=3493"}],"version-history":[{"count":35,"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/posts\/3493\/revisions"}],"predecessor-version":[{"id":9165,"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/posts\/3493\/revisions\/9165"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/media\/3549"}],"wp:attachment":[{"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/media?parent=3493"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/categories?post=3493"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/myholisticdentist.com\/wp-json\/wp\/v2\/tags?post=3493"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
