Hearing "root canal treatment", many people immediately think of sharp pain and expensive costs, so they hesitate or ignore it. In fact, delay only causes inflammation to spread, leading to tooth loss, jaw bone infection, and even affecting overall health. The important thing is to clearly understand the standard root canal treatment process, know step by step what the doctor will do to ensure safety, no pain and keep the tooth for a long time.
So how does the root canal treatment process take place? We invite you to follow this in-depth article. The content is compiled based on the sharing of Doctor Hoang Vy, specialist in implantology and endodontic treatment at the Lac Viet Intech Dental System, and will help you clearly understand the standard root canal treatment process according to the Ministry of Health.
Root canal treatment(also known as root canal treatment or endodontics) is a specialized dental technique, designed to remove the entire tooth pulp that is infected, necrotic or irreversibly damaged. Then clean, shape the root canal system and seal to prevent bacteria from re-invading. This is an important solution to help preserve real teethinstead of having to remove them, thereby maintaining chewing function and natural aesthetics.
Root canal treatment helps preserve natural teeth as much as possible instead of removing them
According toAmerican Dental Association (ADA), root canal treatment canMaintaining real teeth with a success rate of over 90% if performed according to technical procedures, using medical-standard filling materials and modern equipment.
In Vietnam,Dental root canal treatment process of the Ministry of Healthhas been issued as a standard applicable nationwide. This process includes strict steps fromexamination - diagnosis - anesthesia - opening the pulp chamber - cleaning - shaping - filling - restoration. Most reputable dental clinics today strictly follow this process, to ensure absolute safety, sterility and long-term treatment effectiveness for patients.
Indications for root canal treatment are when the pulp has become inflamed, necrotic or irreversibly damaged. At that time, marrow cells lose the ability to restore themselves. If not removed promptly, the infection will spread to the entire root canal system and the area around the tooth root.
Leaving pulpitis untreated for a long time will cause bacteria to destroy the entire tooth structure, leading to a jaw bone abscess and forcing the tooth to be completely removed. At this time, to ensure chewing function and aesthetics, you will have to undergo restoration using specialized implant methods.

Common clinical situations include:
When cavities destroy enamel and dentin, bacteria Penetrating directly into the pulp chamber causes pan initial inflammatory reaction to eliminate bacteria but causes pressure in the closed pulp chamber, leading tosevere pain.
According to the Journal of Endodontics (2020), more than 70% of root canal treatment cases stem from tooth decay that is not treated early
Serious risks if not treated:
Spread of infection: Bacteria move through the tip of the tooth causing periapical inflammation and alveolar bone abscess teeth, or diffuse inflammation in the maxillofacial area.
Jaw bone damage: Bone loss around the tooth root causes loose teeth and permanent tooth loss.
Systemic infection: In rare but dangerous cases, bacteria from the foci of pulpitis enter the bloodstream causing sepsis which can be life-threatening.
A report by theAmerican Association of Endodontists(2022) shows thatuntreated pulpitis is three times more likely to progress to systemic infectionthan other oral infections
First step, the doctor conducts a thoroughclinical examinationto observe the condition of teeth, gums and surrounding soft tissue. This helps detect signs of inflammation, swelling, bleeding or abnormalities in oral structure.
Next, the patient will have adigital X-raytaken. This is an imaging technique that helps the doctor clearly assess the condition of the tooth pulp, measure the length of the tooth root, detect damage to the alveolar bone or infected foci around the tooth tip that cannot be seen with the naked eye.
Finally, the doctorassesses the overall health of the whole bodyto ensure that the patient is eligible for treatment, especially those with cardiovascular disease, diabetes or blood clotting disorders.
According to research on theJournal of Endodontics(2020), accurate diagnosis combined with digital X-rays reduces the risk of failurein root canal treatment by38%
The doctor will do a clinical examination before root canal treatment
The doctor useslocal anestheticto completely eliminate pain during the treatment process. The type of anesthetic and dosage are calculated based on each patient's health condition and pain threshold.
After anesthesia, arubber damplaced around the tooth needing treatment. This is an important tool to isolate teeth from saliva, prevent bacteria from entering the root canal, and help the treatment area stay completely dry and sterile.
Local anesthesia is given to the patient to eliminate pain
Doctor createdopening into the pulp chamberthrough the chewing surface for molars, or the lingual surface for incisors and canines. The opening is designed to best facilitate access to the entire root canal system.
Then the whole thingpulp tissue is inflamed or necroticRemoved with specialized tools such as hand or machine tools. This process requires high precision to avoid missing diseased tissue or damaging the root canal wall.
Root canal will dowashwith a disinfectant solution such as Sodium Hypochlorite (NaOCl) or Chlorhexidine, which helps remove bacteria and tissue debris and prevent reinfection.
Cleans the oral cavity and opens the pulp
Combined Doctorapex locatorwith X-ray images to accurately measure the working length of the root canal. This is an extremely important step, because if done too short, diseased tissue will be missed, and if done too long, it will damage periapical tissue, leading to pain and complications after treatment.
Measure the length of the root canal
Shaping the root canalis performed with hand files or machine files to expand and shape the root canal system. The goal is to create a regular cone shape, making it easier to seal later.
According toCochrane Review(2016), proper filling techniques can help prolong the life of root canal treated teeth by an average of10–15 years.
After root canal treatment, the tooth will lose a large amount of hard tissue, becoming brittle and prone to breaking. Depending on the level of damage, the doctor will choose the appropriate restoration option:
Direct filling with compositeif most of the tooth tissue is still strong.
Ceramic crownif the tooth has lost a lot of hard tissue or is in a position subject to high chewing force, to protect and restore maximum aesthetics.
Welding with specialized materials
Lower molars usually have 2-3 roots, inside which contain a complex root canal system with many interwoven, zigzag and difficult-to-reach secondary canals. This anatomical feature makes the root canal treatment process of lower jaw teeth much more difficult than other tooth locations. To achieve optimal results, the doctor needs to:
Accurately locate each root canalwith length measuring devices and supporting software, avoiding missing hidden root canals.
Use a dental microscopeto magnify and clearly observe the entire internal structure, helping to detect even small or calcified root canals.
Perform the pulp cleaning process multiple timeswith specialized solutions, ensuring complete removal of bacteria and debris. necrotic pulp debris and toxins.
According toResearch published in the journal Clinical Oral Investigations (2019), root canal treatment of lower molarshas a higher risk of failure than upper molarswithout the support of a dental microscope. This shows the importance of modern technology in increasing success rates and prolonging tooth life after treatment.
Acute pulp inflammation:Usually completed in 1–2 appointments.
Necrotic or abscessed pulp:Requires 2–4 appointments to completely clean out.
The cost of root canal treatment is not fixed but varies depending on many factors:
Number of root canals: Teeth with many root canals (such as molars) require longer work time and effort, so the cost is higher.
Tooth location: Teeth in difficult-to-reach locations (especially lower molars) are often more difficult to manipulate, requiring sophisticated and time-consuming techniques.
Skills and Doctor's experience: A highly specialized doctor who has performed many complex root canal treatments will bring a higher success rate.
Supporting technology: The use of dental microscopes, electronic apex locators, modern mechanical files, etc. helps improve efficiency and safety but also affects the price.
Reference price list in Vietnam(common level in clinics):
Tooth door: 1,000,000 – 2,000,000 VND/piece.
Small molars: 1,500,000 – 3,000,000 VND/piece.
Major molars: 3,000,000 – 4,000,000 VND/piece.
Root canal treatment requires absolutely precise technical procedures and strict adherence to aseptic principles. If the procedure is performed incorrectly, the patient may encounter serious complications:
Apical periodontitis: Due to bacteria or remaining necrotic pulp tissue, causing inflammation at the root tip.
Prolonged pain after treatment: Occurs when the pulp remains or the root canal is not thoroughly cleaned.
Fracture of instruments in the root canal: A complication that is difficult to handle, can cause the root canal to become clogged and increase the risk risk of reinfection.
Recurrent infection: When the filling material is not sealed or the filling technique is not standard, the bacteria will re-enter, destroying the tissue around the tooth.
According to research published in theJournal of Endodontics(2018), up to14% of root canal treatment failuresoriginate from non-compliance with standard procedures and inadequate aseptic control enough
To maintain long-term root canal treatment results and avoid complications, patients need to:
Limit vigorous chewingon the treated tooth, especially in the first few days, to avoid tooth fracture.
Follow the follow-up scheduleaccording to the doctor's instructions to monitor healing and detect any unusual signs early.
Maintain optimal oral hygiene Pros: Use a soft-bristled toothbrush to brush your teeth at least twice a day, combine dental floss and antiseptic mouthwash to clean plaque between teeth.
Root canal treatment requires high technology, modern equipment and experienced doctors, because even a small mistake can lead to recurrent inflammation, prolonged pain or even permanent tooth loss.
