Root Canals Treatment or Endodontic Treatment


Has your dentist or endodontist told you that you need root canal treatment?
If so, you're not alone.

Millions of teeth are treated and saved each year with root canal or endodontic treatment. Learn how root canal treatment can relieve your tooth pain and save your smile in Bangkok. To understand a root canal procedure, it helps to know about the anatomy of the tooth. Inside the tooth, under the white enamel and hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue, and helps to grow the root of your tooth during development. In a fully developed tooth, the tooth can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.

Endodontic treatment treats the inside of the tooth. Endodontic treatment is necessary when the pulp becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can caused pain or lead to an abscess.



During root canal treatment, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed with a rubber-like material called gutta-percha. Afterward, the tooth is restored with a crown or filling for protection. After restoration, the tooth continues to function like any other tooth. Root canal in Bangkok takes only a few visits.



Modern root canal treatment is very similar to having a routine filling and usually can be completed in one or two appointments, depending on the condition of your tooth and your personal circumstances. You can expect a comfortable experience during and after your appointment of having root canal in Bangkok.

Saving the natural tooth with root canal treatment has many advantages:
  • Efficient chewing
  • Normal biting force and sensation
  • Natural appearance
  • Protects other teeth from excessive wear or stain

  • Endodontic treatment helps you maintain your natural smile, continue eating the food you love.

    Endodontic Therapy (Root Canals Treatment in Bangkok)

    Endodontic therapy or root canal therapy is a sequence of treatment for the infected pulp of a tooth which results in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion. Root canals and their associated pulp chamber are the physical hollows within a tooth that are naturally inhabited by nerve tissue, blood vessels and other cellular entities which together constitute the dental pulp. Endodontic therapy involves the removal of these structures, the subsequent shaping, cleaning, and decontamination of the hollows with small files and irrigating solutions and the obturation (filling) of the decontaminated canals with an inert filling.



    Endodontists are dentists who have trained after their basic dentist's training so as to become a specialist in the field of root canal treatment. This advanced training includes the use of specialized equipment.



    If root canal treatment is performed by a general dentist who is not an endodontist or it's not given the attention to detail it requires, it can fail in catastrophic manner. The most common reason for failure is infection. This is when patients are often referred by a general dentist to an endodontist for further management (that is, re-treatment of the root canal) – or advised to have an extraction. At Promjai Dental Clinic, patients can be confident with our root canal services by endodontists in Bangkok.

    Step-By-Step Root Canals Treatment in Bangkok


    Root Canal Treatment doesn't cause pain, it relieves it.

    Dental Microscope for Root canals Treatment

    Why is the microscope so crucial in endodontic treatment carried out by a registered specialist?

    A key development in the success of root canal treatment in Bangkok is the use of high-powered microscopes. The operating dental microscope allows the operator to see the inside of a tooth and the root canal system at a magnification of up to 20 times, with added lighting.

    This is important because:
  • teeth often have extra roots or canals that cannot be seen with the naked eye or loupes (glasses with magnification)
  • crowns or big fillings in teeth often make it difficult to see the inside of a tooth, and special light from the microscope is required to see the floor of these teeth
  • Often teeth can have fractures or other abnormal anatomy, and these can be detected and treated early, rather than after the event – when treatment fails.

  • Advances in technology and training of root canal treatment in Bangkok have for some time allowed endodontists to enjoy a high success rate. Contrary to outdated perceptions, treatment doesn't require multiple visits and need not be painful at all.

    Endodontic Retreatment

    With proper care, even teeth that have had root canal treatment in Bangkok can last a lifetime. But sometimes, a tooth that has been treated doesn't heal properly and can become painful or diseased months or even years after treatment. If your tooth failed to heal or develops new problems, you have a second chance. An additional procedure may be able to support healing and save your tooth. If you have pain or discomfort in a previously treated tooth, talk to an endodontist about retreatment.

    Why do I need another endodontic procedure?

    As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:



  • Narrow or curved canals were not treated during the initial procedure.
  • Complicated canal anatomy went undetected in the first procedure.
  • The placement of the crown or other restoration was delayed following the endodontic treatment.
  • The restoration did not prevent salivary contamination to the inside of the tooth.


  • In other cases, a new problem can jeopardize a tooth that was successfully treated. For example:



  • New decay can expose the root canal filling material to bacteria, causing a new infection in the tooth
  • A loose, cracked or broken crown or filling can expose the tooth to new infection.
  • A tooth sustains a fracture.


  • During retreatment, the endodontist will reopen your tooth and remove the filling materials that were placed in the root canals during the first procedure. The endodontist the carefully examine the tooth, looking for additional canals or new infection. The endodontist then removes any infection, clean and shapes the canals and places new filling materials. The opening is then sealed with a temporary filling. Once the tooth heals, a new crown or other restoration is placed on the tooth to protect it. These few steps can be easily done for just one or two appointments in Bangkok.

    Dental Symptoms

    Even with proper brushing and flossing habits, and regular dental check up, you can have problems with your teeth and gums. Tooth pain, injury, increased sensitivity to hot or cold, and oral or facial swellings are just some of the signs of potential dental problems. Read about common dental symptoms to help you understand the causes and possible solutions for your tooth pain.

    Abscessed Teeth

  • An abscess is a painful infection at the root or in the gum of a tooth. It occurs when the pulp, the soft tissue inside the root canal, becomes inflamed or infected and goes untreated.
  • A toothache is the most common symptom of an abscess, but you may also experience pain when chewing, tooth sensitivity to hot and cold, swelling of the gums, or other symptoms. If you have ongoing pain or suspect an abscess, see an endodontic who specializes in treating infected teeth and pulp.
  • A dental abscess is usually treated with root canal treatment. An endodontist will remove the inflamed or infected area, clean, shape and fill the root canals, and seal the space. You will return to your dentist, who will place a crown or other restoration on the tooth to protect and restore it to full function. After restoration, the tooth continues to function like any other tooth.

    Cracked Teeth

    Cracked teeth show a variety of symptoms, including erratic pain when chewing, possibly with release of biting pressure, or pain when your tooth is exposed to temperature extremes. In many cases, the pain may come and go, and your dentist may have difficulty locating which tooth is causing the discomfort.



    There are many different types of cracked teeth. The treatment and outcome for your tooth depends on the type, location and extent of the crack.



    Craze Lines

    Craze lines are tiny cracks that affect only the outer enamel. These cracks are extremely common in adult teeth. Craze lines are very shallow, cause no pain, and are of no concern beyond appearances.



    Fractured Cusp

    When a piece of a tooth's chewing surface breaks off, often around a filling, it's called a fractured cusp. A fractured cusp rarely damages the pulp, and usually doesn't cause much pain. Your dentist can place a crown over the damaged tooth to protect it.


    If breathing through your mouth or drinking cold fluids is painful, bite on clean, moist gauze or cloth to help relieve symptoms until reaching your dentist's office. Never use topical oral pain medications (such as Abseil) or ointments, or place aspirin on the affected areas to eliminate pain symptoms.



    Cracked Tooth

    A cracked tooth means a crack extends from the chewing surface of your tooth vertically toward the root. The tooth is not yet separated into pieces, though the crack may gradually spread. Early diagnosis is important in order to save the tooth. If the crack has extended into the pulp, the tooth can be treated with a root canal procedure.


    However, if the crack extends below the gum line, it is no longer treatable, and the tooth cannot be saved and will need to be extracted. That's why early treatment is so important. A cracked tooth that is not treated will progressively worsen, eventually resulting in the loss of the tooth. Early diagnosis and treatment are essential in saving these teeth.



    Split Tooth

    A split tooth is often the result of the long term progression of a cracked tooth. The split tooth is identified by a crack with distinct segments that can be separated. A split tooth cannot be saved intact. The position and extent of the crack, however, will determine whether any portion of the tooth can be saved. In some cases in Bangkok, root canal treatment may be performed to save a portion of the tooth.



    Vertical Root Fracture

    Vertical root fractures are cracks that begin in the root of the tooth and extend toward the chewing surface. They often show minimal signs and symptoms and may therefore go unnoticed for some time. Vertical root fractures are often discovered when the surrounding bone and gum become infected. Treatment may involve extraction of the tooth. However, endodontic surgery is sometimes appropriate if a portion of the tooth can be saved by removal of the fractured root.
