White Spots on Front Teeth, Mottled Teeth Treatment Case / Icon Resin Treatment Method / 강남레옹치과

Hello, this is 강남레옹치과🙂

When you look closely at your teeth,

there are cases where unusually white stains or spots

stand out.

Especially when these spots appear on the front teeth, they can easily be noticed when you smile or talk, which may lead to cosmetic concerns.

These white spots on the teeth are called “mottled teeth,” and it is important to choose an appropriate treatment method based on their cause and the condition of the teeth.

In this post, we will take a look at a case of mottled teeth treatment performed at 강남레옹치과 using Icon Resin.

White Spots on the Teeth:

What Are Mottled Teeth?

Mottled teeth refers to white or opaque spots on the tooth surface that differ from the surrounding teeth.

Due to optical differences caused by the structure of the enamel on the tooth surface, the spots may appear brighter and more opaque than the surrounding teeth. Their causes and depth can also vary.

Common examples include:

✔️ Enamel formation abnormalities that occurred while the teeth were developing

✔️ White spots caused by early demineralization

✔️ Demineralization occurring before or after orthodontic treatment

✔️ Enamel changes related to fluoride

✔️ Changes in tooth development caused by trauma or other factors

Therefore, rather than focusing only on removing the white spots, it is important to first determine their cause, depth, and extent.

What Is Icon Resin?

Several methods may be considered for treating mottled teeth, depending on the condition of the teeth.

Among them, Icon Resin (ICON Resin Infiltration) does not involve extensively removing and covering the tooth surface. Instead, a low-viscosity resin is infiltrated into the porous enamel

in order to reduce the optical difference of areas that appear prominently white.

✋Question✋

How is Icon Resin different from conventional mottled-teeth treatments?

Category	Teeth Whitening	Resin·Veneers	Icon Resin
Purpose	Improve the overall color of the teeth	Improve the color and shape of the tooth surface	Reduce the color difference of white spots
Treatment method	Brighten the tooth color using a whitening agent	Directly restore the tooth surface with a material or attach a restoration	Infiltrate low-viscosity resin into the enamel
Mottled-teeth treatment	The color difference between the spots and surrounding teeth may remain	May be selectively considered depending on the condition of the spots	Improve the appearance by reducing optical differences in the spotted areas
Tooth reduction	None	May be necessary depending on the treatment method and tooth condition	Minimize tooth reduction
Suitable cases	Teeth that are generally yellowish	Cases involving deep or extensive discoloration where improvement of the tooth shape is also needed	Spots such as white spots where Icon Resin can be applied
Recommended areas	Cases requiring improvement of the overall tooth color	Cases requiring improvement of both color and tooth shape	Cases where treatment is needed while considering preservation of the natural teeth

Not all mottled teeth cases receive the same treatment.

The appropriate treatment method may vary depending on the overall tooth color, the depth and extent of the spots, and whether improvement of the tooth shape is needed.

For mottled-teeth treatment, rather than saying that there is “one best method,” the most important thing is to choose the method that best suits the condition of the teeth and the patient’s expectations.

Assessing Each Patient’s Tooth Condition

Even when the diagnosis is the same, every patient’s tooth condition is different.

Mottled teeth does not simply mean white stains that have appeared on the teeth.

The location, depth, and extent of the spots vary from patient to patient, and different issues may also occur in the color or shape of the surrounding teeth.

For example,

✅ Spots + a fractured front tooth

If the tip of a front tooth is chipped along with the white spot, both improvement of the spot and the shape of the fractured tooth must be considered.

✅ Spots + yellowish teeth

If the overall tooth color is yellowish and spots are also present, treating only the spots may make the color difference more noticeable, so the overall shade is considered as well.

✅ Spots + front teeth of different lengths

If the lengths or edges of the front teeth are uneven along with the spots, the proportions and symmetry of the teeth are examined and the necessary treatment is planned.

✅ Mottled spots on children’s front teeth

White spots may also appear on children’s permanent teeth. After checking the development of the teeth and the cause of the spots, the necessity and timing of treatment are determined.

It is important to carefully assess the depth and extent of the spots, as well as the color and shape of the surrounding teeth, and plan treatment with an emphasis on preserving the natural teeth as much as possible.

When necessary, teeth whitening, tooth reshaping, and front-tooth resin treatment may be performed together with Icon Resin.

Icon Resin Treatment Process

Icon Resin treatment differs from conventional resin treatment, which simply adds resin to the tooth surface.

After pretreating the tooth surface, the resin is allowed to sufficiently penetrate into the enamel where the spots appear.

The treatment is then performed step by step so that the color difference from the surrounding teeth can be naturally reduced.

① Check the tooth condition and spot depth

The location and extent of the spots are accurately examined before treatment.

② Special acid treatment and resin infiltration

The tooth surface is pretreated in stages so that the resin can penetrate into the enamel.

③ Infiltration of Icon Resin into the spots

Icon Resin is sufficiently infiltrated into the spotted areas.

④ Light curing and finishing

After curing the resin, the tooth surface is refined and its harmony with the surrounding teeth is checked.

Actual Case

This patient visited the clinic because of concern about white spots on the surface of the front teeth.

The examination showed that there were no significant problems with the shape or alignment of the front teeth themselves.

However, part of the tooth surface appeared more opaque and brighter than the surrounding enamel. As a result, the area looked relatively more prominent when the patient smiled.

After checking the location, extent, and depth of the spots, Icon Resin treatment for mottled teeth was performed to reduce the color difference while minimizing damage to the natural teeth.

Treatment of mottled teeth using Icon Resin is not suitable for every case, but it tends to have high satisfaction among the following patients:

✔️ People whose white spots on the front teeth look particularly prominent

Those who are concerned about tooth stains when smiling or talking

✔️ People who want to minimize damage to their natural teeth

Those who want cosmetic improvement while preserving their existing teeth as much as possible, rather than undergoing extensive tooth reduction

✔️ People concerned about color imbalance rather than tooth shape

Those whose tooth shape or alignment is not significantly problematic, but who have a noticeable color difference in a specific area

✔️ People who want to improve mottled teeth using a less burdensome method

Those who want to improve white spots on their teeth with a relatively simple method rather than restorative treatment

✔️ People who want a result that harmonizes with the surrounding natural teeth

Those who want natural-looking improvement that considers the color and translucency of the existing teeth, rather than artificially covering only the spotted area

Differences in Mottled-Teeth Treatment Experience:

The Highest Domestic Use of Icon Resin in 2025

Even when the condition is the same, not all patients have identical tooth conditions.

The appearance of mottled teeth varies widely, from white spots with distinct color and boundaries to spots that are broadly spread or differ in depth.

Therefore, it is important to identify the condition through an examination and determine the treatment range and method for each tooth.
