What is Root Canal Treatment?
10.02.2026

This is a treatment method applied when a tooth becomes infected or decayed due to various reasons. It is a procedure performed by cleaning the tooth and then sealing the inner part with a filling.

For patients experiencing dental problems, if bacteria in the tooth reach the nerve endings, dentists examine the tooth and perform root canal treatment if deemed necessary. Otherwise, it may lead to tooth loss. Root canal treatment protects the tooth from decay or infection. People who do not want to experience toothache are advised to undergo root canal treatment. Removing the nerves during the procedure does not cause any harm to the patient; on the contrary, it prevents tooth pain. This is a brief explanation of what root canal treatment is.

How Long Does Root Canal Treatment Take?

Root canal treatment is carried out depending on the level of decay in the patient’s tooth. While the treatment process may be completed in a single session for some patients, it may take two or three sessions for others. A person who will undergo root canal treatment must first be examined by a specialist dentist. Then, based on the necessary examinations, it is decided whether this treatment is required.

  • To prevent pain during root canal treatment, the inside of the mouth is first numbed.
  • After numbing, necessary precautions are taken to prevent water from entering the tooth and oral cavity.
  • Using a special instrument, the dentist opens and cleans the inside of the tooth. The nerves inside are then removed.
  • After the root canal treatment is completed, the hole opened in the tooth may be permanently filled on the same day by some dentists, while others may apply a temporary filling. After a short period and once the required results are achieved, it is permanently sealed.

The answer to the question of how long root canal treatment takes depends on the extent of damage to the tooth based on the steps mentioned above.

Can a Tooth That Has Undergone Root Canal Treatment Decay?

First of all, root canal treatment is performed due to damage to the tooth. To avoid experiencing the same pain again, the patient must pay close attention to oral hygiene. The treated tooth may be affected by decay occurring in neighboring teeth. At the same time, the answer to the question “can a tooth that has undergone root canal treatment decay?” is yes. The patient must perform dental care regularly and without interruption after treatment. If it is noticed that the treated tooth has decayed, the patient should immediately consult the same dentist.

What Are the Symptoms of Failed Root Canal Treatment?

This conclusion is reached when the tooth becomes reinfected after root canal treatment. The symptoms of unsuccessful root canal treatment usually become noticeable weeks or months later. If we ask what the symptoms of failed root canal treatment are, the following list would be accurate:

  1. If the pain complained of by the patient does not subside after treatment and instead becomes more severe, this indicates a problem with the treatment.
  2. After root canal treatment, swelling in the face or around the mouth should subside within two days. Otherwise, the treatment has been unsuccessful.
  3. Conditions such as nasal congestion or discharge may also indicate this outcome.

In such cases, the patient should act according to the dentist’s recommendations. In unsuccessful root canal treatment, the tooth may be extracted or refilled.

How Should Dental Care Be Performed After Root Canal Treatment?

Patients undergo root canal treatment to eliminate dental complaints. To avoid experiencing the same pain again, proper care must be taken after treatment. For example, teeth should be brushed morning and evening, and dental floss should be used.

  • After root canal treatment, the mouth should be rinsed gently with mouthwash.
  • To avoid experiencing the same dental health problems again, regular oral hygiene must be maintained.

The answer to the question of how dental care should be performed after root canal treatment is explained through this list. If any dental problems occur, you should обязательно consult your dentist again.
