Saving your natural teeth
Precision Root Canal Treatment

What is Root Canal Treatment?

Root Canal Treatment (endodontic therapy) removes the infected nerve and blood-vessel tissue inside the tooth caused by a cavity or trauma, disinfects the canals, and then fills them to preserve the tooth. It can save your natural tooth instead of extraction Conservative careis our standard.

We remove the infected pulp and precisely clean and fill the canals to preserve your natural tooth. It is the final conservative option before extraction.

Root Canal Treatment, here’s how it works

Knowing each step in advance eases anxiety

Diagnosis Cleaning Filling Prosthodontics
1

Diagnosis & Anesthesia

X-ray·3D CT to accurately assess the extent of infection. With sufficient anesthesia, we start without pain.

About 10 minutes No pain (under anesthesia) 3rd-floor treatment room
Please eat before treatment. Eating may be difficult for 2~3 hours after anesthesia.
2

Root canal access & cleaning

Under 25x microscopic magnification, we precisely remove infected nerve tissue. We thoroughly disinfect the canals with ultrasonic irrigation.

About 30~40 minutes No pain (anesthesia maintained) 25x microscopic magnification
This step is critical. We locate and treat fine canals that are invisible without a microscope.
3

Root canal shaping & filling

We precisely shape the canals with Ni-Ti rotary files, then fill them tightly with a sealing material (GP points). We measure the exact length with an electronic apex locator.

About 20~30 minutes A slight pressure sensation Electronic apex length measurement
Depending on the infection status, treatment may be divided into 2~3 visits. In between, we protect the tooth with a temporary filling.
4

Crown Placement

A tooth after Root Canal Treatment becomes weaker, so we place a crown to restore normal chewing force. It is made to match your natural tooth color.

About 30 minutes (2 visits) No pain Natural tooth preserved
Treatment complete! A crown typically lasts 10~15 years or more. Keep it healthy with regular checkups.

Total treatment time About 2~3 weeks, 2~4 visits

Frequently Asked Questions

Find answers to your questions

With adequate anesthesia, there is little to no pain during treatment. You may feel mild discomfort for 1~2 days afterward.

Yes. Teeth become weaker after Root Canal Treatment, so placing a crown protects the tooth and helps prevent fractures.

Typically 2~3 visits over 1~2 weeks. It may take longer if the infection is severe.

Slight discoloration can occur, but placing a crown resolves the esthetic concern.

Modern Root Canal Treatment is performed under thorough anesthesia, so there is little to no pain during the procedure. Many patients with dental anxiety still receive it, and if you are very anxious, Sedation Dentistry is available. Delaying treatment can actually make the pain worse.

Tooth root Inside the tooth's root canals, completely removing the infection usually requires 2~3 visits. If the infection is severe, additional visits may be needed, and thorough disinfection improves long-term success.

Root Canal Treatment (endodontic treatment) is performed when the nerve (pulp) inside a tooth becomes infected or necrotic due to a cavity or trauma. The infected tissue is removed, then the inside is disinfected and filled. It is an important treatment to save the tooth without extraction.

Because it is done under adequate anesthesia, there is little to no pain during treatment. In fact, the toothache before treatment is often much worse. Mild discomfort for 1~2 days afterward can be managed with pain relievers.

Once the nerve is removed, blood supply to the tooth stops, and it can become dry and weakened. That is why it is standard to place a crown (restoration) after Root Canal Treatment to protect the tooth.

Usually 2~3 visits are required. Depending on how severe the infection is, more visits may be needed, and the interval between visits is 1~2 weeks. For acute pain, we provide emergency care first and then proceed step by step.

If the infected nerve is left untreated, pus can form at the tip of the tooth root (Periapical abscess) and the infection can spread to the surrounding bone. Swelling of the face and severe pain may occur, and extraction may eventually become unavoidable.

With proper Root Canal Treatment plus protection with a Crown, the tooth can last a long time. However, there is a risk of reinfection, tooth fracture among other risks, so Regular checkupsare important. The success rate is about 90–95%.

At Seoul BD Dental, we provide precise Root Canal Treatment using digital X-rays and an electronic apex locator. A specialist provides the treatment directly, maximizing the chance of saving your tooth with a minimally invasive approach.

Pain may temporarily worsen between visits. This is a reaction as the medication works on the nerve and can be managed with pain relievers. However, if you have significant swelling or fever, please visit us immediately.
