The Principles of Teeth Whitening at Gangnam Station and Aftercare for Maintaining a Bright Smile

Summary
1. Teeth whitening is a treatment that uses the oxidizing action of hydrogen peroxide to chemically break down organic staining substances accumulated on and inside the tooth surface.
2. The causes of tooth discoloration are divided into external factors, such as food and smoking, and internal factors, such as aging, pulp necrosis, and medication use. Diagnosis according to the cause is essential.
3. Temporary tooth sensitivity may occur after the procedure, so aftercare is necessary, including avoiding irritating foods and limiting foods that can cause staining.

Hello,

This is New En Dental Clinic.

The key principle of teeth whitening lies in the oxidizing action of the hydrogen peroxide contained in the whitening agent. When a professional whitening agent used at a dental clinic is applied to the tooth surface, it decomposes and releases reactive oxygen species. These reactive oxygen species penetrate the enamel, the outermost layer of the tooth, and the dentin beneath it.

The process then breaks the carbon bonds of the organic staining substances that make the teeth appear darker and decomposes them into tiny particles. This helps restore the teeth’s natural bright, radiant shade without damaging the tooth structure itself.

Factors That Cause Tooth Discoloration

Extrinsic discoloration is closely associated with everyday eating and lifestyle habits. Coffee, green tea, black tea, red wine, chocolate, and curry, which many people commonly enjoy, contain powerful pigments such as tannins and polyphenols.

As people age, the transparent enamel on the outside of the teeth gradually wears down and becomes thinner through years of chewing, while the yellowish dentin underneath becomes thicker. As a result, the teeth may appear generally darker and more yellow.

In addition, intrinsic discoloration may occur when certain antibiotics were taken excessively during early childhood or when trauma to a tooth causes the nerve inside it to become necrotic, resulting in a dark reddish discoloration.

Because this type of discoloration may be difficult to resolve with ordinary whitening, a detailed diagnosis is necessary to determine whether the treatment is appropriate.

Characteristics of Professional Whitening

Professional whitening involves applying a high-concentration hydrogen peroxide whitening agent to the tooth surfaces at a dental clinic and then using a special light device to activate the whitening ingredients and rapidly break down the pigments.

Because a dental professional thoroughly applies a special protective agent to protect the patient’s gums before performing the procedure, it offers a high level of safety. In most cases, a session lasting approximately one hour during a single visit can produce a noticeable improvement in brightness within a short period.

It is particularly popular among office workers with limited time or people with important events approaching.

Aftercare for Maintaining Brightness After the Procedure

For at least several weeks after the procedure, foods that can cause staining should be limited. It is advisable to avoid strongly colored foods such as curry, black bean sauce noodles, and kimchi stew, as well as beverages such as coffee, cola, and red wine.

If you must drink such beverages, using a straw may be a practical tip to reduce direct contact between the beverage and the tooth surfaces.

In addition, after eating, rinse your mouth with water as soon as possible and brush your teeth before the pigments settle onto the teeth.

Q. Tooth Sensitivity After Whitening

A. Temporary tooth sensitivity that occurs immediately after the procedure should be managed appropriately.

During the whitening process, moisture inside the teeth may temporarily escape, and nerve stimulation may make the teeth sensitive to cold water or air. However, this is generally a common temporary phenomenon that naturally disappears within 2–3 days.

While symptoms are present, avoid excessively cold or hot irritating foods and continue your aftercare according to the instructions provided by the dental clinic.

Maintaining a recall system that includes regular dental visits, oral hygiene checkups, and scaling is a proper way to preserve the smile you have achieved for a long time while keeping it healthy.
