Hello.
I am Seo Ho-yeon, the director of Yonsei Dagam Dental Clinic, located near Gaerong Station. ^^
Have you ever noticed a white, mottled area on your front tooth while looking in the mirror?
It may not appear to be a cavity, but it can stand out noticeably and become a source of concern whenever you take photos.
As a result, more people than you might expect visit us for a consultation.
White spots that appear on the surface of the teeth often do not pose a significant health concern.
However, when they are located in the center of a front tooth, they remain visible when you smile or speak, which can lead to stress.
Today, I would like to introduce a case involving Icon resin treatment for a patient who visited us because of a white spot on a front tooth.

A White Spot on a Front Tooth Visible When Smiling
The patient said that the white spot visible in the center of the front tooth had been bothering them for a long time.
From the front, it may not appear particularly noticeable.
However, when light shines on it or when speaking with someone at close range, it becomes more conspicuous because its shade differs from that of the surrounding teeth.
White spots are often caused by microscopic demineralization beneath the tooth surface.
They may appear after orthodontic treatment, or changes in the enamel that developed during childhood may remain into adulthood.
Although the causes vary, they commonly share the characteristic of appearing white because the structures beneath the tooth surface reflect light differently from those of a normal tooth.
For this reason, scaling or whitening alone often does not produce a significant improvement.

In this patient’s case as well, the tooth appeared white because of differences in its internal optical properties rather than a problem with the surface.
We therefore planned Icon resin treatment without filing down the tooth.
Conventional resin treatment involves removing the portion of the tooth containing the spot and restoring the resulting cavity with resin.
By contrast, Icon resin treatment does not involve filing down the tooth. Instead, a very small amount of the tooth surface is dissolved using a strong acid, and Icon resin that can penetrate the tooth surface is applied to reduce the appearance of the spot.
However, the same results cannot be expected for every white spot.
Because the outcome may vary depending on the cause, depth, and extent of the white spot, it is important to determine in advance through an accurate diagnosis whether the treatment is appropriate.

In particular, if the white spot extends into the deeper part of the tooth, or if a demineralized lesion associated with an early cavity has progressed, it may be difficult to achieve sufficient improvement with Icon resin alone.
Therefore, it is advisable to accurately diagnose the current condition before treatment, discuss the expected extent of change thoroughly, and then decide whether to proceed with Icon resin treatment.

Thorough Isolation Before Treatment
First, we isolated the treatment area so that the teeth and gums outside the treatment site would not be affected.
Because Icon resin treatment uses a strong acid, the isolation process is very important. Without proper isolation, the neighboring teeth and gums could be affected.


Repeated Acid Treatment and Monitoring of the Changes
We checked the condition after the first acid treatment.
As shown in the photo, the white spot was still visible.
Patients sometimes ask, “Won’t it disappear after just one treatment?”
Depending on the depth and extent of the white spot, several rounds of treatment may be necessary.
In this case as well, we determined that additional treatment was needed. After monitoring the condition of the white spot, we performed acid treatment a total of three times before carrying out the Icon resin treatment.


In the photos taken after treatment, you can see that the area in the center of the front tooth that had appeared white blended much more naturally with the surrounding teeth.



In the close-up photos taken after treatment, you can see that the white spot had almost disappeared even though the tooth was neither removed nor treated with a prosthetic restoration.
Of course, treatment results may vary depending on the cause, depth, and extent of the white spot, and the same changes seen in this case cannot be expected in every situation.
However, when the condition is appropriate for this treatment, Icon resin can be considered before proceeding with treatment that involves removing tooth structure.
In addition, because Icon resin can be infiltrated into the white-spot area and may help reduce the extent of the lesion, it has the advantage of potentially reducing the amount of tooth structure that needs to be removed if additional resin treatment is required later.

Today, I introduced a case in which a white spot was improved with Icon resin treatment without removing tooth structure.
Some people who are concerned about white spots on their front teeth consider veneers or crowns from the outset.
However, depending on the cause and extent of the white spot, it may be possible to first consider methods that minimize the removal of tooth structure.
At Yonsei Dagam Dental Clinic near Gaerong Station, we assess the location and depth of the white spot and the condition of the tooth before consulting with patients on whether Icon resin treatment is appropriate.
If the white spot on your front tooth bothers you every time you take a photo, please have your current condition accurately diagnosed.
If you have any further questions about Icon resin, please call us or visit the clinic at any time. We will be happy to provide a kind consultation.
This has been Seo Ho-yeon, director of Yonsei Dagam Dental Clinic near Gaerong Station.

I hope you have a peaceful day today as well. 😊
