مقدمه
درمان ریشه دندان (عصبکشی)، یکی از رایجترین و ضروریترین روشهای دندانپزشکی برای حفظ دندان آسیبدیده است. این درمان معمولاً باعث از بین رفتن درد ناشی از عفونت یا پوسیدگی شدید میشود، اما برخی بیماران بعد از درمان، دچار درد، ناراحتی یا حساسیت میشوند. در این مقاله از دندانپزشکی دکتر فربد سیفی و دکتر فرزانه داشخانه، به بررسی دقیق دلیل درد بعد از درمان ریشه دندان و روشهای مدیریت آن میپردازیم.
آیا درد بعد از درمان ریشه دندان طبیعی است؟
بله. احساس درد خفیف تا متوسط برای چند روز بعد از درمان ریشه طبیعی است. دلیل این درد معمولاً تحریک بافتهای اطراف ریشه، التهاب موقت یا واکنش بدن به درمان است. However, if the pain persists or increases in intensity, there may be a problem that needs to be investigated.
Main causes of pain after root canal treatment
In the following, we introduce the most important reasons that may cause pain after denervation:
1. Inflammation of the tissue around the root
During root canal treatment, the tissues around the tooth may be slightly irritated. This irritation can cause temporary inflammation, resulting in mild to moderate pain, which is usually manageable with anti-inflammatory medications.
2. Residual infection
If the infection is not completely cleared from the dental canals, the infection may remain after the treatment and cause pain, swelling and sometimes fever. In such a situation, there is a need to re-treat or use antibiotics.
3. Excessive or insufficient filling of the channel
One of the common causes of pain is incomplete or excessive filling of dental canals. If the filling materials extend beyond the tip of the root or the canals are not completely filled, inflammation and pain will occur.
4. Tooth root crack or fracture
In some cases, a denervated tooth has a crack or fracture in the root. This can lead to permanent pain and sometimes there may be a need to extract the tooth.
5. Too much pressure when chewing
After root canal treatment, the tooth may become very sensitive to pressure. If the temporary or permanent crown is not properly adjusted or there is too much pressure on the tooth, pain will occur.

How many days does the pain last after root canal treatment?
In a normal state, pain or discomfort continues between 3 and 7 days after the treatment and gradually decreases. If the pain becomes more severe or lasts more than a week, you should definitely see a dentist. The specialized team of Dr. Farbad Seifi and Dr. Farzane Dashkhane are always ready to check your condition.
How to control pain after root canal treatment?
1. Taking prescribed medications
After treatment, the dentist may prescribe pain relievers such as ibuprofen or acetaminophen to control pain and inflammation. Antibiotics are also necessary if there is an infection.
2. Avoid chewing food with the desired tooth
Until the tooth is completely restored and receives a permanent cover, direct pressure on it should be avoided.
3. Observance of oral hygiene
Regular brushing and use of antibacterial mouthwash helps to reduce inflammation and prevent secondary infection.
4. See a dentist on time
In case of increased pain, fever, purulent discharge or swelling of the face, you should go to the dentist immediately.
The difference between normal pain and abnormal pain after root canal treatment
| Features | natural pain | abnormal pain |
|---|---|---|
| Duration | 3 to 7 days | more than a week |
| intensity | mild to moderate | acute and chronic |
| Drug reaction | improvement with housing | No effect or escalation |
| Accompanied symptoms | without severe fever and swelling | with fever, swelling or bad breath |
Bone dryness and persistent pain after root canal treatment
In some cases, the bone tissue around the root of the tooth may become inflamed or so-called "bone dryness". This condition occurs due to mechanical damage or remaining contaminated materials around the root and can cause chronic pain. The treatment of this condition depends on draining the area, washing it again and sometimes prescribing antibiotics.

What is the treatment of chronic pain after denervation?
If the pain persists beyond normal, the dentist may do one of the following after the examination:
-
Re-treatment of the root (re-treatment)
If the canals are not properly cleaned or filled. -
Apicoectomy surgery
In cases where retreatment does not work and the tip of the root is inflamed. -
Tooth extraction
If the tooth has a vertical fracture or uncontrollable infection.
Is it necessary to use veneers after root canal treatment?
Yes. Root-treated teeth usually have a weak structure and are more prone to fracture. Using a veneer protects the tooth from chewing pressure and reduces the possibility of pain or subsequent damage.
Dentist's role in reducing pain after root canal treatment
Dentist's skill and experience play an important role in the success of root canal treatment and pain reduction afterwards. Choosing the right materials, complete disinfection of the canals, and precise adjustment of the filling are among the factors that must be performed by an experienced dentist. The professional team of Dr. Farbad Seifi and Dr. Farzane Dashkhane provide accurate and pain-free treatment for patients using modern equipment and specialized knowledge.
FAQs about pain after root canal treatment
Is pain after denervation a sign of treatment failure?
Not necessarily. In most cases, minor pain is normal. But if the pain is severe or continuous, a more detailed investigation should be done.
Can you eat after root canal treatment?
Yes, but you should avoid eating solid foods or chewing with treated teeth for a while.
Is root canal treatment always successful?
The success rate of root canal treatment is high, but factors such as complex tooth anatomy, chronic infection or lack of care can reduce success.
