Hello.

This is Haruplant Dental Clinic, where a comfortable daily life begins in a day.

Teeth are one of the first things people notice when you speak or smile. White, well-aligned teeth give a clean and neat impression, so many people consider teeth whitening for a brighter smile.

However, teeth whitening is not just about making teeth white. Tooth discoloration is divided into external staining and internal discoloration, and the key to treatment is to clearly diagnose which one it is and then apply the appropriate procedure.

Today, we’ll share some useful information to know before teeth whitening. Causes of Tooth Discoloration As mentioned earlier, tooth discoloration is divided into external staining and internal discoloration.

External staining refers to a condition where the tooth surface becomes yellowish and darker due to frequent consumption of strongly colored foods such as coffee, wine, or curry, or because of smoking.

In addition, poor oral care can allow tartar and debris to build up over many years, or certain medications, a history of trauma, or root canal treatment can cause tooth color to gradually become more yellowish and dark than before.

In such cases, the issue can be resolved by removing the pigments or discoloring substances attached to the tooth surface, so depending on the desired level of brightness, only a few treatment sessions may be enough to achieve a lighter shade.

By contrast, internal discoloration is a phenomenon in which the color becomes dull from deep within the tooth. If the natural tooth color is yellowish and dark due to genetic factors, or if the enamel that protects the tooth is thin and the inner dentin shows through, the color can appear dull.

In such cases, whitening procedures have limitations in achieving the desired color, so we recommend other treatment methods that can overcome structural issues. Whitening Procedure at Haruplant Dental Clinic

Before whitening, the patient’s tooth color is diagnosed using a shade guide.

A shade guide is a tool divided into steps that allows tooth color and brightness to be measured for comparing before and after whitening procedures or for making prosthetics.

Through this, we diagnose which shade the patient’s tooth color and brightness belong to, and after the whitening procedure is finished, we can objectively check how much change has occurred.

After measurement, the tooth surface is cleaned so the whitening agent can be applied evenly. Then resin is applied to prevent irritation to the gums, completing preparation.

Once all preparations are finished, the whitening agent is placed on the tooth surface to a thickness of 1–2 mm, and then a special laser is applied for a certain period of time. Through this process, oxidation occurs, breaking down the discoloring substances stained on the tooth surface and allowing the original color to be restored.

By repeating this process several times, the tooth color becomes one to two shades lighter than before. Finally, the change before and after whitening can be confirmed again by comparing with the shade guide. Limitations of Whitening Procedures

Typically, even one whitening session can make teeth one to two shades lighter. However, results vary from person to person depending on the condition, and it may be difficult to improve as much as desired.

In addition, whitening is not permanent, so teeth can become yellow again over time, and regular retreatment is needed to maintain the result. This is especially true in cases caused by congenital factors or internal discoloration, where noticeable improvement may be difficult to expect.

In such cases, Haruplant Dental Clinic’s Harunate program may be worth considering. Harunate not only improves color, but also neatly organizes the shape and alignment, so even without whitening procedures, it can help maintain white and well-aligned teeth for a long time. Today, we looked at the causes of tooth discoloration and Haruplant Dental Clinic’s whitening procedure.
