Hello, for cases of severe tooth decay causing pulp inflammation, many people wonder how much root canal treatment and dental filling costs and whether the cost is high. The doctor will clearly explain each issue from a professional perspective so that you can properly understand the nature of the treatment and avoid confusing a regular filling with endodontic treatment.
How much does root canal treatment and dental filling cost?
The doctor’s direct answer is: dental filling after root canal treatment includes two separate costs: root canal treatment (endodontic treatment) and restoration of the tooth crown using filling material. The total cost usually ranges from approximately 1–3 million VND per tooth, depending on the tooth’s location and the extent of damage.
If you are specifically asking how much it costs to fill a decayed tooth after root canal treatment, it is important to understand that when tooth decay has spread into the pulp chamber, the doctor must clean the root canal system, disinfect it, and obturate the root canals before restoring the tooth externally. The root canal treatment accounts for most of the cost because it requires advanced techniques, strict infection control, and specialized equipment.
The cost is lower for front teeth because they usually have only one root canal. In contrast, molars may have 3–4 root canals, so the treatment cost is higher. Therefore, when researching the cost of root canal treatment and dental filling, you need to consider the overall procedure rather than calculating only the external filling.
Factors affecting the cost of root canal treatment and dental filling
Treatment costs are not fixed and depend on various professional factors. The doctor always conducts a thorough examination and takes X-rays before determining the specific cost.
Extent of pulp damage
If the pulp is only mildly inflamed and the inflammation has not spread extensively, cleaning and shaping the root canals will be simpler. In cases of suppurative pulpitis, pulp necrosis, or periapical abscess, the treatment process is more complex and requires multiple appointments, resulting in higher costs.
Number of root canals requiring treatment
Front teeth usually have 1 root canal, while molars may have 2–4 root canals with curved, narrow, and difficult-to-access anatomy. The greater the number of root canals, the longer the treatment time and the higher the cost.
Filling material used
After root canal treatment, the tooth becomes more brittle and susceptible to fracture due to the loss of its nutritional supply. Choosing the appropriate restorative material is very important. Standard aesthetic composite has a different cost compared with high-strength materials or advanced restorative techniques. This is also a factor affecting how much root canal treatment and dental filling costs.
Dentist’s expertise and equipment
Endodontic treatment requires a dentist with experience, a thorough understanding of root canal anatomy, and precise techniques to avoid missed canals or root perforation. Equipment such as an apex locator, rotary instrumentation systems, and radiographic imaging for assessment also directly affects treatment quality and cost.

Dental filling procedure after root canal treatment
The dental filling procedure after root canal treatment usually includes the following steps:
- Rechecking the root canal system that has been obturated: The doctor evaluates the tooth clinically and through X-rays to ensure that the root canals have been thoroughly cleaned and completely sealed, with no residual bacteria.
- Creating retention and treating the filling cavity surface: The portion of tooth tissue lost due to decay or access to the pulp chamber will be reshaped to increase the adhesion of the material. The tooth surface is cleaned and isolated from moisture to ensure the durability of the filling.
- Placing the filling material layer by layer: Composite material is placed in thin layers, with light curing after each layer to ensure adequate hardness and strength while minimizing material shrinkage.
- Anatomical shaping of the tooth crown: The doctor reshapes the tooth according to its proper biological structure, ensuring that the contact point and occlusal surface are appropriate for the natural bite.
- Checking the occlusion and performing final polishing: This is an important step to prevent discomfort when eating and chewing. Finally, the tooth surface is polished to help minimize staining and plaque accumulation.
The entire procedure needs to be performed meticulously because if the restoration is not carried out properly, a tooth after root canal treatment can easily crack, fracture, or become reinfected by bacteria. In some cases where a significant amount of tooth structure has been lost, the doctor may consider placing a dental crown instead of using only a filling to ensure long-term durability.
After root canal treatment, should the tooth be filled or crowned?
This is a very important question. If the remaining tooth structure is still strong and healthy and the amount of lost tooth structure is not too extensive, a restorative filling may be sufficient. However, for molars that bear significant chewing forces or teeth with substantial loss of tooth structure after root canal treatment, a dental crown is often recommended to protect the remaining structure and reduce the risk of cracks and fractures.
The doctor always considers the balance between maximum preservation of the natural tooth and ensuring long-term durability. Not every case requires a dental crown, but it is also unwise to simply place a filling when the tooth has already become significantly weakened.
If you are experiencing pain caused by tooth decay and are concerned about the cost of root canal treatment and dental filling, the doctor recommends having an early examination at Gangwhoo Cosmetic Hospital for an accurate assessment. In addition to treating tooth decay, the hospital also provides professional teeth whitening services to improve tooth color after restoration, helping you achieve a healthier and naturally brighter smile.
