Cheonggudong Dental Clinic: Don't Miss the Timing for Cavity and Root Canal Treatment
Cavities, which anyone can experience, are often taken lightly. However, the longer they are left untreated, the more they can damage not only the tooth but also the nerves inside, causing excruciating pain that can disrupt daily life. Since permanent teeth, once damaged, cannot regenerate, meticulous care and consistent management are essential.

Cavities, commonly referred to as tooth decay, occur when food particles trapped between teeth after eating are not properly brushed away. The acids produced by the decay of these food particles then damage the tooth.
Cavities do not stop once they appear; they gradually spread and deepen over time, making early detection and treatment crucial for this oral disease. However, in the early stages, there is often little to no pain, so many people are unaware of the cavity until it progresses and pain begins.

It is especially difficult to detect cavities when they occur between teeth or on the inner surfaces that are hard to see, rather than on the visible front teeth or the top of the tooth. In such cases, even when pain occurs, people often do not suspect a cavity.
Therefore, to diligently manage oral health, it is important to visit Cheonggudong Dental Clinic regularly for check-ups or to undergo scaling to completely remove plaque and tartar, which cause cavities. These efforts are necessary for cavity prevention and early detection.

Cavities progress through stages 1 to 4. Stage 1 (enamel cavity) is when the cavity only affects the outer surface of the tooth, and patients often don't feel any pain, making them unaware of its presence. If you experience a sharp or sensitive sensation when eating, it's likely Stage 2 (dentin cavity), where the cavity has invaded the dentin, located just below the enamel.

Fortunately, for Stage 1 and 2 cavities, the decayed part can be removed and treated with relatively simple methods such as resin, inlays, or onlays. However, if the cavity has progressed beyond Stage 2 and invaded the pulp (tooth nerve), reaching Stage 3, then a more complex root canal treatment, rather than a simple Cheonggudong Dental Clinic cavity treatment, must be performed.

Root canal treatment at Cheonggudong Dental Clinic is performed using MTA material, which has excellent biocompatibility and sealing properties compared to traditional root canal materials. When a cavity requires root canal treatment, the natural tooth often has less than 50% remaining and is significantly weakened, making it difficult to perform normal tooth functions. Therefore, crown treatment is often performed concurrently to preserve the remaining natural tooth.

Fortunately, up to Stage 3, which involves root canal treatment, it is still possible to treat and preserve the natural tooth for continued use. However, a cavity that has progressed beyond Stage 3 to Stage 4 has already affected not only the tooth but also the periodontium (gums) that support and hold the tooth. At this stage, the tooth may be loose, or there may be so little tooth structure remaining that conservative treatment is difficult. In such cases, treatment must proceed with extraction and the placement of an artificial tooth. This treatment is what you commonly know as implant treatment.
In other words, since root canal treatment is the last stage at which a natural tooth can be saved, it is crucial to prevent the cavity from spreading further. To do so, diligent brushing, regular check-ups, and scaling are essential habits.

At Cheonggudong Dental Clinic, the chief director, certified by the Ministry of Health and Welfare in integrated dentistry, provides thorough care from consultation to cavity treatment, root canal treatment, and post-treatment management. Most importantly, the director personally provides 1:1 responsible care, ensuring stable dental treatment.


Before starting any dental treatment, Cheonggudong Dental Clinic has adopted a 3D-CT precision diagnostic system to meticulously examine the patient's current oral condition and establish a personalized treatment plan. This equipment helps us identify even areas that are difficult to see with the naked eye, ensuring comprehensive care.
Furthermore, to alleviate the burden of pain that patients might feel during treatment, Cheonggudong Dental Clinic utilizes a digital pain-free anesthesia system to help patients receive dental care comfortably.

At Bareunyoung Dental Clinic, we provide comprehensive, one-stop treatment for common cavity and root canal treatments, as well as implants, periodontal treatment, aesthetic treatment, and temporomandibular joint treatment. Even with severe cavities, we prioritize exploring methods to save natural teeth before recommending implant treatment, and all treatments at Cheonggudong Dental Clinic are performed with the preservation of natural teeth as the primary consideration.

Frequently Asked Questions
Why is early treatment important for cavities?
Early detection and treatment are crucial for cavities because, although they cause little pain initially and are hard to spot, they can gradually spread deep, damage the tooth nerve, and cause severe pain over time.
How do cavity treatment methods differ by stage?
Stage 1-2 cavities can be treated relatively simply by removing the decayed part and using resin or inlays. If the cavity has invaded the pulp (nerve) in Stage 3, root canal treatment is performed. For Stage 4, tooth extraction and implants are necessary.
When is root canal treatment necessary?
Root canal treatment is needed when a cavity progresses beyond Stage 2 and invades the pulp (tooth nerve), reaching Stage 3. This stage is the last opportunity to preserve the natural tooth, so prompt treatment is vital.

Cheonggudong Dental Clinic employs a 3D-CT precision diagnostic system to meticulously assess the patient's current oral condition and establish a customized treatment plan, identifying even areas difficult to see with the naked eye.
