What Is The Most Commonly Encountered Microorganism In Pulp And Periapical Infections

Root Canal Infection – Is it causing health symptoms?

There were a total of eight species of microbes collected. Peptostreptococcus and Streptococcus spp. were frequenters. Bacteria that sing during their digestions, such as Prevotella and Porphyromonas spp., have a black-pigmented appearance. A similar pattern was seen with infectiouss in the primary pulp area as well. As with previous studies, these results are consistent.

So If I Need A Root Canal Or Already Have One What Should I Do

If you knew you had an infection in your jaw thats draining pus from your tooth and retreating the root canal wont fully resolve it what would you do? The most important thing is to get the right imaging. You know the typical Xrays they take in the dental office? They sometimes dont show an infection if its there, even if it is a fairly large one. Why is this? Its because the infection and pus is in your jaw, and the bone essentially masks it or hides it. The only way to be sure of what is going on is to take a 3D image of the teeth called a cone beam. This technology is becoming more available in dentistry and more dental offices and specialists are using it for their patients because of the accuracy and the information provides.

Here is an example. In the picture to the right you see a normal dental Xray of tooth #3 which has an existing root canal. So what do you see? Well, not much. There is no clear sign of a problem. And if you combine this with the fact that this patient has no symptoms, most dentists would take a look at the tooth ask if there was any pain anywhere. If the answer was no, they pass on by and not think twice about it.

This image corresponds with the root canal tooth shown in the Xray above. These images allow us to see a tooth from all angles just like we are rotating the tooth. In this way we can see if there is a problem or not. Extremely important with root canal teeth.

What Should One Expect After Root Canal Therapy

Root canal therapy should relieve the pain you feel. Until your root canal procedure is completely finished — that is, the permanent filling is in place and a crown, if needed, is in place — it’s wise to minimize chewing on the tooth under repair. This step will help avoid recontaminating the toothâs interior and also may prevent a fragile tooth from breaking before the tooth can be fully restored.

For the first few days following the completion of treatment, the tooth may feel sensitive due to natural tissue inflammation, especially if there was pain or infection before the procedure. This sensitivity or discomfort usually can be controlled with over-the-counter pain medications such as ibuprofen or naproxen . Most patients can return to their normal activities the next day.

As far as oral health care is concerned, brush and floss as you regularly would, and see your dentist at normally scheduled intervals. Because the final step of root canal therapy is application of a restoration such as a crown or a filling, it will not be obvious to onlookers that a root canal was performed.

Root canal treatment is highly successful the procedure has more than a 95% success rate. Many teeth fixed with root canal therapy can last a lifetime.

How Is A Secondary Root Canal Infection Treated

When a root canal is treated for the second time, it is more commonly referred to as a retreatment. A retreatment is performed the same way as a typical root canal procedure, including the use of antibiotics. If a retreatment is not sufficient, there is a surgery that can be performed known as an apicoectomy. This procedure relieves the infection by accessing it through the bony area around the tooth, instead of through the top of the tooth.

When To Worry About A Tooth Infection

If you suspect you have a dental abscess, dont wait until it ruptures to seek treatment. Dental infections should be treated promptly to prevent the spread of the infection.

Common symptoms of a dental infection that requires urgent dental care include:

  • Noticeable sore under the gums
  • Swelling and inflammation near the affected tooth
  • Bad taste in the mouth
  • Loose tooth
  • A severe, throbbing toothache that doesnt go away
  • Swollen and painful lymph nodes in the neck
  • Pain when chewing or biting down


Tooth abscesses are dental emergencies. They need to be drained by a professional quickly to prevent spreading. A noticeable sore and severe, throbbing pain are the most common symptoms.

How Long Can a Tooth Infection Go Untreated?

If you wait too long to treat a tooth infection, it can begin spreading to other areas of your body, including the neck, head, or jaw. A general dentist must professionally drain an abscessed tooth by extracting it or performing a root canal.

Usually, this includes draining pus and bacteria, which is why some people are actually unaware they have an infection. It is unpredictable to determine how long a dental abscess will drain until it stops and causes facial cellulitis .

You should never pop or squeeze an abscess because the infection can be pushed deeper into the tissues of your mouth.

Risks of not treating a tooth infection promptly:


Complications Of Root Canal Therapy

Despite your dentist’s best efforts to clean and seal a tooth, new infections might emerge. Among the likely reasons for this include:

  • More than the normally anticipated number of root canals in a tooth
  • An undetected crack in the root of a tooth
  • A defective or inadequate dental restoration that has allowed bacteria to get past the restoration into the inner aspects of the tooth and recontaminate the area
  • A breakdown of the inner sealing material over time, allowing bacteria to recontaminate the inner aspects of the tooth
  • Sometimes re-treatment can be successful. Other times, endodontic surgery must be tried in order to save the tooth. The most common endodontic surgical procedure is an apicoectomy, or root-end resection. This procedure relieves the inflammation or infection in the bony area around the end of your tooth. In this procedure, the gum tissue is opened, the infected tissue is removed, and sometimes the very end of the root is removed. A small filling may be placed to seal the root canal.

    Since 2000 there have been great innovations in the art and science of root canal therapy. Dentists now must be educated on the current concepts in order to optimally perform a root canal procedure. Root canal therapy has become more automated and can be performed faster thanks in part to machine-driven rotary technology and more advanced root canal filling methods. Many root canal procedures are done in one dental visit which may last for around 1â2 hours. Newer technologies are available that allow more efficient, scientific measurements to be taken of the dimensions of the root canal, however, the use of CT scanning in endodontics has to be justified. Many dentists use dental loupes to perform root canal therapy, and the consensus is that procedures performed using loupes or other forms of magnification are more likely to succeed than those performed without them. Although general dentists are becoming versed in these advanced technologies, they are still more likely to be used by root canal specialist .

    Laser root canal procedures are a controversial innovation. Lasers may be fast but have not been shown to thoroughly disinfect the whole tooth, and may cause damage to the tooth.

    What If I Have An Infection Before The Root Canal

    If you are experiencing an infection before your root canal procedure is performed, you may have an antibiotic prescribed to you in order to treat the infection. If you have an active infection during root canal therapy, there is a chance the infection can block the anesthetic from working and numbing the area. It is important to talk with your dentist about your symptoms, and follow their recommendations for treating the infection first, then the full tooth.

    Filling The Root Canal

    Is My Root Canal Tooth Infected | Ask Blodgett Dental Care

    The standard filling material is gutta-percha, a natural polymer prepared from latex from the percha tree . The standard endodontic technique involves inserting a gutta-percha cone into the cleaned-out root canal along with a sealing cement. Another technique uses melted or heat-softened gutta-percha which is then injected or pressed into the root canal passage. However, since gutta-percha shrinks as it cools, thermal techniques can be unreliable and sometimes a combination of techniques is used. Gutta-percha is radiopaque, allowing verification afterwards that the root canal passages have been completely filled and are without voids.

    An alternative filling material was invented in the early 1950s by Angelo Sargenti. Filling material has undergone several formulations over the years , but all contain paraformaldehyde. The paraformaldehyde, when placed into the root canal, forms formaldehyde, which penetrates and sterilizes the passage. The formaldehyde is then theoretically transformed into harmless water and carbon dioxide. According to some research, the outcome of this method is better than a root canal procedure performed with gutta-percha. There is, however, a lack of indisputable scientific studies according to the Swedish Council on Health Technology Assessment.

    What Is Root Canal Surgery

    Endodontic surgery refers to the Greek words meaning inside and tooth . In fact, a root canal is only one of the types of endodontic therapy, referring to the treatment of the soft tissue inside of teeth, called the pulp, which plays a significant role in a tooths development and growth. When a tooth is fully formed, it can survive without the pulp due to the surrounding tissues. In this paragraph, we will cover all the stages of root canal surgery, including:

  • Performing dental x-rays
  • Creating an opening and removing the decayed pulp
  • Medicating the opening
  • Restoring the tooth.
  • Removing The Infected Pulp

    If a follow-up visit is scheduled for a root canal procedure, then the dentist will likely start by numbing the tooth to minimize discomfort during treatment. They will then carefully access the root of the tooth where the infection is present. Using either small dental tools or laser dentistry, the dentist will then remove the infected, decayed or damaged pulp material in the root of the tooth.

    Getting A Root Canal Replacement

    Sometimes a root canal procedure does not permanently solve the problem of an abscessed tooth. You may break the tooth long after the root canal therapy, allowing bacteria to enter. A root canal dentist can offer a root canal replacement to help you heal. If you lose pieces of your tooth, your dentist may use a composite resin to rebuild the tooth before adding a root canal crown.

    The Origins Of Root Canal Infections

    What is Root Canal &  Treatment Works?

    While root canal causes vary, they all start the same way: with an injured tooth. Whether its a crack or chip in the tooth, a fractured tooth root, damage to the tooth pulp or a tooth having repeated dental procedures, they can all lead to root canal system infections.* However, the number one cause of root canal system infection is tooth decay.**

    Before causing a root canal system infection, the decay must first develop beyond the tooth enamel, which is the hardest structure in your bodyits even harder than bone!** Factors such as the thickness and quality of the enamel can determine how long it takes for a cavity to form, but it is typically within monthswhich is why your dentist wants to see you bi-annually for checkups.***

    Its when you dont attend checkups that your tooth decay is likelier to penetrate through the enamel and into the next layer of the tooththe dentinthat you become at risk of a root canal infection. Once the decay progresses through the dentin and reaches the tooth pulp, microorganisms in the tooth decay can cause inflammation, which promotes bacteria growth and the spread of infection.
