1
What is Root Canal Treatment?
Root Canal Treatment (Endodontic) is performed when the tooth’s nerve (pulp) becomes infected or dies due to a cavity or trauma; the infected nerve is removed, and the canals are disinfected and filled.
2
Does Root Canal Treatment hurt?
We begin only after adequate anesthesia, so there is little to no pain during the procedure.
3
Does a tooth become weaker after Root Canal Treatment?
Once the nerve is removed, blood supply to the tooth stops, and the tooth can become more brittle and weak.
Root Canal Treatment (Endodontic) Frequently Asked Questions 20 items
Root Canal Treatment (endodontic therapy) is performed when the tooth’s internal nerve (pulp) is infected or necrotic due to a Cavity or trauma; the infected tissue is removed, the inside is disinfected, and the canals are filled. It is an important way to preserve a tooth without extracting it.
With adequate anesthesia, there is little to no pain during treatment. In fact, the toothache before a root canal is usually much worse. You may feel mild discomfort for 1~2 days afterward, which can be controlled with pain relievers.
Once the nerve is removed, blood supply to the tooth stops, so it can become dry and more fragile. For this reason, it is standard to place a Crown (restoration) after Root Canal Treatment to protect the tooth.
Typically, 2~3 visits are needed. Depending on the degree of infection, more visits may be required, with 1~2 weeks between appointments. In cases of acute pain, we provide emergency care first and then proceed step by step.
If an infected nerve is left untreated, tooth root at the tip, pus (Periapical abscess) can develop, and the infection may spread to the surrounding bone. This causes facial swelling and severe pain, and extraction can ultimately become unavoidable.
With proper Root Canal Treatment plus protection with a Crown, it can last a long time. However, reinfection, tooth fracture are possible risks, so Routine checkupsare important. The success rate is about 90~95%.
At Seoul BD Dental, digital X-rayand an electronic apex locator enable precise Root Canal Treatment. An endodontic specialist performs the treatment directly, maximizing the chance of preserving the tooth with a minimally invasive approach.
Pain may temporarily worsen between visits. This is a reaction as medicaments used during treatment act on the tissues, and it can be managed with pain relievers. However, if significant swelling or fever occurs, please visit us immediately.
In most cases, we recommend covering the tooth with a Crown (restoration). After Root Canal Treatment, the tooth loses its moisture supply, becomes dry, and is more prone to breaking. Especially molarshave strong biting forces, so using them without a Crown increases the risk of fracture.
As time passes after Root Canal Treatment, the tooth can become darker. This occurs as residual blood components break down. internal whiteningcan be improved with (walking bleach), and for front teeth Laminate Veneeror a Crown can restore esthetics.
It’s when bacteria are not completely removed after treatment or re-infection occurs, causing symptoms to return. If inflammation at the root tip (periapical lesion) remains, Root Canal Retreatment or perform apical surgery (Apicoectomy). Success rates: initial treatment about 90-95%, retreatment about 70-85%.
Root Canal Treatment is covered by Korean NHIS, and your out-of-pocket portion is about 30,000-100,000 KRW (approx. $22-$73), depending on tooth position and number of roots. However, the Crown placed afterward may be non-covered (out-of-pocket) depending on the material, so we will explain the total cost during your consultation.
During treatment (when you have a temporary filling), avoid chewing hard foods on that tooth. The temporary filling may come out, and the weakened tooth can fracture. Chew on the opposite side, and if the temporary filling comes out, please visit us right away.
When infection recurs in a previously treated tooth, we remove the old filling materials and disinfect and fill the canals again. It is more complex than the initial treatment, but often the last chance to avoid extraction and save the tooth.
When standard Root Canal Treatment or Root Canal Retreatment cannot solve the problem, we open the gum and remove the infected root tip.dental operating microscope under which we perform with high precision, and as the last Conservative Treatment approach.
Yes. If significant reduction is required for prosthetic treatment, or if a cavity is very close to the nerve, we may perform preventive Root Canal Treatment. Root Canal Treatment is also needed when a fractured tooth exposes the nerve.
The principle is the same, but front teeth usually have one root, so treatment is relatively simpler. Molars have 3-4 roots and more complex canal anatomy, so treatment is more difficult and takes longer. Costs also vary with the number of roots.
Yes, both baby teeth and permanent teeth can all receive Root Canal Treatment. For baby teeth, we often perform partial nerve treatment (pulpotomy) instead of full Root Canal Treatment to preserve the baby tooth until the permanent tooth erupts normally.
Because the nerve has been removed, the tooth itself does not feel pain, but if the area around the root tip (apex) in the gum or bone becomes inflamed again, pain can occur. This is called "apical periodontitis," and it can be resolved with Root Canal Retreatment or apical surgery (Apicoectomy).
Yes, that's normal. The smell comes from the disinfectants used inside the root canal (sodium hypochlorite, calcium hydroxide etc.), and it fades as treatment progresses. These agents are used at concentrations safe for the human body.
