Root canal treatment prices in 2026 + Build-up (filling) cost

Root canal treatment prices in 2026 vary depending on the tooth type, number of root canals, and treatment complexity. Typically, the cost for front teeth is lower, while the cost for molars is higher due to the greater number of canals. Additionally, the build-up (filling or reconstruction of the tooth after root canal treatment) cost is calculated separately.

Your frequently asked questions about root canal treatment costs

Does the number of tooth roots affect the cost of a root canal?

Yes, the more canals and roots a tooth has, the longer and more complex the treatment will be. For this reason, root canal treatment for multi-rooted teeth is generally more expensive than for single-rooted teeth.

Can a broken tooth still undergo root canal treatment?

If the tooth root is healthy, in many cases it is possible to perform the root canal first and then proceed with reconstruction or crowning. The feasibility is determined after examination and X-ray evaluation.

Does a wisdom tooth root canal cost more?

In many cases, yes. Due to its position, difficult access, and complicated root canals, a wisdom tooth may cost more than other teeth.

Does laser root canal treatment cost more?

If advanced equipment such as lasers or supplementary technologies are used, the treatment cost may increase.

Does delaying a root canal increase the overall treatment cost?

Yes, delaying treatment can lead to the spread of infection, further damage to the tooth, and the need for additional procedures, which ultimately raises the final treatment cost.

How is root canal treatment cost calculated?

The cost of root canal treatment in Iran is determined based on the following factors:

Tooth type: Root canal treatment for front teeth is generally less expensive than for molars.
Number of root canals: The more canals there are, the higher the treatment cost.
Degree of infection or tooth damage: Severe infection or complicated cases can increase the cost.
Need for retreatment: Retreatment (Re-Treatment) has a higher fee due to its greater difficulty.
The dentist’s expertise and experience: Seeing a root canal specialist (endodontist) in Sa’adat Abad or other northern and western areas of Tehran usually costs more than visiting a general dentist.
Equipment and technology used: The use of advanced tools such as rotary files, apex locators, or dental microscopes can affect the treatment cost.
Additional treatments: If a build-up, post and core, crown, or radiography is needed, the fees for these services are calculated separately.

How much does the build-up (filling) cost after a root canal?

The cost of build-up (rebuilding or filling the tooth after root canal treatment) is calculated separately from the root canal cost. The build-up fee, if tooth rebuilding is required, will be added to the final treatment price.

Is a dental crown always needed after a root canal?

No, not all root canal‑treated teeth require a crown. The need for a crown depends on the extent of tooth destruction, its location, and the amount of remaining healthy tooth structure. Generally, molars that bear more chewing pressure are more likely to need a crown after root canal treatment; however, for some front teeth or teeth with minor damage, a build‑up or appropriate restoration may be sufficient without a crown.

Cost Comparison: Root Canal vs. Tooth Extraction + Implant

When a tooth becomes infected or deeply damaged, the patient faces two treatment paths: saving the tooth with a root canal, or extracting it and replacing it with an implant. Although extraction may seem like the simpler option at first glance, there is a significant difference in cost and treatment time between the two approaches.

Root canal treatment typically preserves the natural tooth and does not require more complex surgical and restorative procedures. In contrast, the extraction-plus-implant route involves several separate steps (extraction, implant placement, and final crown), each with its own independent cost, which can significantly raise the total final fee.

In the table below, we have briefly reviewed both common treatment paths along with the costs of each step for you.

Treatment Stage	Root Canal Path	Extraction + Implant Path
Stage 1	Root canal: Price inquiry via WhatsApp	Extraction: Price inquiry via WhatsApp
Stage 2	Build-up (filling after root canal): Price inquiry via WhatsApp	Implant (without crown): Price inquiry via WhatsApp
Stage 3	Crown (if needed, optional)	Implant crown (zirconia with prosthetic components): Price inquiry via WhatsApp
Approximate Total	Price inquiry via WhatsApp	Price inquiry via WhatsApp
Treatment Time	Usually 1 to 3 sessions	Several months (from extraction to implant placement and final crown delivery)
Likelihood of Additional Costs	Low (possible need for a crown) Price inquiry via WhatsApp	Higher (possible need for bone graft or sinus lift)

As shown in the table, in most cases the cost of root canal treatment and build-up is less than half the cost of extraction and implant, even in the most economical implant scenario. For this reason, in cases where the tooth is treatable, root canal treatment is usually considered a more cost-effective option both in terms of cost and time; however, the final decision should be made after a clinical examination and assessment of the tooth’s actual condition by the dentist.

Additional costs of root canal treatment that you should know before treatment!

Radiography (X-Ray or OPG) cost: Before and sometimes during treatment, imaging is needed to assess the root status, number of canals, and extent of tooth damage. This cost is charged separately.
Build-up (tooth reconstruction) cost: After a root canal, if a large portion of the tooth crown is lost, a build-up is required to strengthen and prepare the tooth.
The cost of post and core: If the tooth does not have enough structure to support a crown, a post and core may be used to increase the tooth’s strength, the price of which is calculated separately from the root canal treatment.
Crown cost after root canal: Some teeth, especially molars, need a crown to prevent fracture. The crown cost varies depending on the selected material.
Retreatment cost: If the previous treatment is unsuccessful or an infection recurs, root canal retreatment may be needed, which is usually more expensive than the initial root canal.
Cost of treating tooth infection or abscess: If the tooth has a severe infection or abscess, additional treatments may be needed before or simultaneously with the root canal, which incurs a separate cost.
Cost of treating damage to surrounding teeth: Long-term infection can affect surrounding tissues, gums, and jawbone, leading to the need for additional treatments.

Why is root canal treatment for molars more expensive?

The cost of root canal treatment for molars is generally higher than for front teeth, because these teeth have a more complex structure and their treatment requires more time and precision. The most important reasons for the higher cost include:

Higher number of root canals
More difficult access to the tooth
Possibility of extra canals or root curvature
Greater need for reconstruction and crowning

What is the difference between a regular filling and a build-up after root canal treatment?

Regular fillings and build-ups are two different procedures that are often confused due to their similar names. A regular filling is done to repair tooth decay in a living tooth without the need for a root canal, and it replaces a small amount of tooth structure. A build-up, however, is specifically for teeth that have had root canal treatment; because the tooth structure becomes weak and brittle after the root canals are emptied, a larger and stronger filling (build-up) is needed to restore the lost structure and prepare the tooth for a crown or final restoration.

Feature	Regular Filling	Build-up After Root Canal
Application	Repairing decay in a living tooth	Rebuilding the tooth after root canal treatment
Prerequisite	Does not require root canal treatment	Only performed after root canal treatment
Volume of restoration	Small to moderate	Large (replaces a significant portion of the tooth crown)
Final purpose	Preserving aesthetics and function of a healthy tooth	Withstanding chewing pressure and preparing for a crown
Cost in (2026)	Usually less than a build-up	Price inquiry via WhatsApp
Need for post and core	Usually no	Yes, if extensive crown damage exists

When does a tooth need root canal treatment?

When infection or decay reaches the tooth’s nerve (pulp), the tooth requires root canal treatment. The most important signs include:

Severe and spontaneous pain (especially at night)
Prolonged sensitivity to heat or cold that persists even after the stimulus is removed
Swelling and gum abscess around the tooth
Darkening of the tooth color
Deep decay that has reached the tooth pulp
Severe trauma to the tooth can also cause nerve damage and necessitate root canal treatment, even without decay.

What happens if we don't perform root canal treatment on a tooth?

Infection spreads from inside the tooth to the jawbone and surrounding tissues.
Formation of a dental abscess and pus accumulation, accompanied by increasing pain and swelling.
Development of a cyst at the tooth root, which in advanced stages requires surgery.
Spread of infection to adjacent teeth.
Bone loss in the jaw in the area of the tooth root.
Conversion of local pain into chronic pain, and sometimes headaches or referred pain to the jaw and ear.
Final loss of the tooth and the need for extraction.
Several-fold increase in treatment cost, because replacing the tooth with an implant or prosthesis is usually more expensive than the root canal itself.

How to reduce root canal treatment costs in Tehran?

To reduce the cost of root canal treatment in Tehran, the best approach is to prevent the treatment from becoming complicated and to choose the right services needed. Some effective strategies include:

Treating the tooth at early stages of decay: Early visits before decay reaches the nerve can prevent the need for root canal treatment and additional costs.
Timely examination and X-ray: Early diagnosis of dental issues makes treatment simpler and reduces the likelihood of needing additional procedures such as abscess drainage or retreatment.
Comparing the final treatment cost, not just the initial price: Choosing the cheapest option does not always reduce overall costs, because a low‑quality root canal may require retreatment and additional expenses in the future.
Proper care after root canal treatment: Maintaining oral hygiene, returning for final restoration, and avoiding excessive pressure on the treated tooth reduce the risk of treatment failure and repeat costs.
Choosing the right treatment instead of delaying it: Delaying a root canal may lead to increased infection, further tooth damage, and the need for more expensive treatments such as extraction and implants.
