What Is Drill-Free Icon Treatment?
“I would like to treat my white spots, but I don’t want my teeth to be drilled.”
Drill-free Icon treatment is recommended for patients who feel this way. Icon is a solution launched by the German company DMG in 2009, and it was originally developed to prevent the progression of early-stage tooth decay.
However, it was later discovered that when this transparent solution penetrates white spot lesions, the white areas blend with the tooth’s natural color. Since then, Icon has gained attention as an effective solution for white spot lesions as well.
Ideal For Patients Who:
- Hesitate to smile in front of others due to white spots on the front teeth
- Have tried whitening but did not see improvement in the white spots on the front teeth
- Are concerned about white spots that appeared after orthodontic treatment
- Were told at a dental clinic that drilling would be necessary but wish to avoid it
- Are worried about white spots on a child’s front teeth (aged 15 or older)
Types of Solutions Used
In Icon treatment, three types of specialized solutions are used in sequence. Each solution has a different role, helping to improve the white appearance and enhance long-term stability.
A) Icon etch
Icon etch is the first solution used. Its main component is hydrochloric acid, and it microscopically prepares the enamel surface to allow the solution used later to penetrate more effectively.
B) Icon dry
The second solution is Icon dry. Its main component is ethanol, and it removes moisture from the tooth surface to prepare for the resin to penetrate more deeply and evenly.
C) Icon infiltrant
The final solution used is Icon infiltrant, which allows the resin to penetrate into the white spot lesions. This low-viscosity resin, known as “TEGDMA,” helps bring the refractive index closer to normal, improving the opaque white appearance to a more natural color.
How Icon Improves White Spots
The white appearance of white spot lesions occurs because the internal enamel structure becomes porous, causing light refraction to scatter irregularly.
In Icon treatment, a special solution (resin) penetrates these porous areas, bringing the refractive index closer to that of healthy enamel. This is how visible improvement is achieved.
The white areas regain their natural translucency, improving appearance while also helping to prevent the progression of tooth decay.
Cases Where Icon May Be Difficult / Alternative Treatment Options
In the following cases, Icon treatment alone may not achieve satisfactory results. In such situations, other treatment options (such as direct bonding or laminate veneers) may be used in combination as necessary.
Cases Where Icon May Be Difficult
- Deep or dense white opacity, such as in enamel hypoplasia
- Irregular or uneven tooth surfaces
- Teeth with laminate veneers already placed over the white spot lesions
Treatable, but are more likely to require direct bonding
- Yellow spots
- Glossy white spot lesions with well-defined borders
- White spot lesions with translucent borders
- Multi-layered white spot lesions
- Distinct white spot lesions present only on one side
- Irregular, patchy white spot lesions (sometimes layered)
For Patients Considering Icon Treatment
- “I have been concerned about the white spots on my front teeth for a long time, but every clinic told me drilling was the only option…”
- “I would like to treat my white spots, but I prefer not to drill healthy teeth…”
For patients with these concerns, Icon can be an attractive treatment option. However, Icon is not suitable for all cases of white spots.
At our clinic, we carefully evaluate each case and value working together with our patients to determine the best treatment approach.
At our clinic, white spot lesions are treated by dentists who have a deep understanding of Icon treatment. With advanced clinical judgment and technical expertise, we are able to treat even challenging cases. We have seen improvement in many cases previously declined by other clinics.
