How to Save a Tooth with Root Canal Treatment image 1

Hello.

When tooth pain, cavities, or sensitivity make dental health poor, root canal treatment is the method that can preserve a natural tooth as a last resort.

It is a precise treatment performed when the nerve and pulp inside the tooth are damaged or infected, and it is effective in restoring function without extracting the damaged tooth.

Many people visit the dentist only after they can no longer endure the pain, but if treatment is delayed in the early stages, the condition may worsen and extraction may become necessary.

Root canal treatment is an important final option for saving a natural tooth, so if you feel pain, it is important to visit the dentist promptly.

0

Let me explain the cases in which root canal treatment is necessary.

0

  1. Nerve damage caused by severe cavities

If cavities progress and infection spreads to the pulp, inflammation or pain may occur inside the tooth. In such cases, the infected pulp must be removed through root canal treatment.

0

  1. Damage caused by trauma

If a tooth is broken due to an accident or external impact, or if the pulp is exposed, the tooth may be saved through root canal treatment.

0

  1. Chronic pulpitis

It often starts with mild pain at first, but if left untreated, persistent inflammation can cause serious problems in the tissues around the tooth.

0

  1. Pulp damage related to gum disease

Severe periodontitis can spread infection from the root area of the tooth and cause nerve damage.

The root canal treatment process

If you need root canal treatment, you may be wondering about the next treatment process. I will introduce the steps.

0

  1. Diagnosis and initial evaluation

At the dental clinic, the condition is checked with an X-ray, and the extent of nerve damage is assessed. If necessary, a pulp test is performed to check the tooth's sensation and blood flow.

0

  1. Local anesthesia and removal of infected pulp

Local anesthesia is administered to minimize the patient's pain, and the infected pulp is removed.

0

  1. Cleaning and shaping of the root canal

After removing the pulp, the inside of the tooth (the root canal) is thoroughly disinfected and shaped appropriately. This step helps prevent infection and prepares the tooth for filling.

0

  1. Root canal filling

The cleaned and disinfected root canal is sealed using a special material, usually gutta-percha. This step prevents further infection and helps maintain stability.

0

  1. Prosthetic restoration

If the tooth has become weak, a crown (artificial tooth crown) is placed to protect it and restore function. This allows the natural tooth to continue being used.
