Early Stage Lesion
This refers to a very early stage in which decay affects only a small part of the enamel surface. If the lesion has stopped progressing, it may sometimes be monitored over time based on the dentist’s clinical judgment.
Permanent teeth are designed to last for life,
but unlike skin, once they are damaged,
they do not naturally regenerate or heal.
At New York S Dental Clinic,
regular checkups, early diagnosis, and timely treatment
help protect your teeth for the long term.
Permanent teeth are meant to last a lifetime. Unlike skin, however, once a tooth is damaged, it does not naturally regenerate or recover on its own.
To keep your teeth healthy for the long term, regular dental checkups, early diagnosis, proper maintenance, and timely treatment are important.
At New York S Dental Clinic, we provide English-speaking cavity treatment in Seoul with careful diagnosis and treatment planning based on the stage of tooth decay.
Tooth decay does not usually become severe overnight. It tends to progress gradually, and the appropriate treatment may differ depending on how far the decay has advanced.
This refers to a very early stage in which decay affects only a small part of the enamel surface. If the lesion has stopped progressing, it may sometimes be monitored over time based on the dentist’s clinical judgment.
At this stage, the decay remains within the enamel and this is often considered one of the best times for treatment. Because there is usually little or no pain, it is often discovered during a routine dental checkup.
At this stage, the decay has progressed into the dentin, which is closer to the nerve. Sensitivity to cold food or hot drinks may begin here, although some people still postpone treatment because the pain is not always constant.
This occurs when decay has progressed to the pulp, the innermost part of the tooth. Severe pain is common at this stage, heat sensitivity may increase, and root canal treatment is often required.
Cavity treatment is selected according to the size of the decay, the remaining tooth structure, and whether the tooth nerve has been affected.
Resin is a tooth-colored material and is commonly used for relatively simple cavities. Because treatment can often be completed in a single visit, it is frequently chosen for smaller areas of decay.
An inlay is a restoration used after the decay is removed and the tooth is shaped. It is fabricated precisely from a tooth-colored material or gold and then fitted into the prepared area of the tooth.
A crown may be used when the decayed area is large or when the tooth has already received root canal treatment. In this treatment, the tooth is covered with a cap-like restoration to protect and reinforce it.
Because cavities are often easier to manage before pain becomes severe.
Qray is an advanced diagnostic device that uses visible light and a special filter to examine the mouth. It can help detect early interproximal caries and other hidden problem areas that may be difficult to identify with the naked eye alone.
Areas with plaque, caries, or cracks may appear as red fluorescence, allowing both the dentist and the patient to check the condition more objectively.
This can support clearer diagnosis, more understandable treatment planning, and more timely decision-making for cavity treatment.
Not every cavity is treated in the same way. Some areas may only need monitoring, while others may require resin filling, inlay treatment, crown treatment, or root canal treatment if the decay has progressed deeply.
At New York S Dental Clinic, the treatment direction is determined after checking the stage of decay, the remaining tooth structure, symptoms, and overall oral condition.
Our goal is not simply to fill a hole, but to preserve the tooth structure appropriately and plan treatment according to each patient’s actual condition.
