After treating tooth decay and removing the affected part, one option to restore the missing area is an “inlay.” Among these, the zirconia inlay has been gaining a lot of attention in recent years.
Zirconia is often referred to as “artificial diamond” because of its exceptional strength and excellent aesthetics. Compared with traditional metal or ceramic materials, it offers many advantages.

✨【Benefits】
1️⃣ High strength and durability
Zirconia is extremely hard and can withstand the strong biting forces of the molars. It is resistant to chipping and wear, making it a long-lasting material.
2️⃣ No risk of metal allergy
Because no metal is used, zirconia inlays are a safe option for patients with metal allergies.
3️⃣ Natural whiteness and aesthetics
The color closely resembles natural teeth, so it does not stand out like silver fillings. It maintains a harmonious and beautiful smile when speaking or laughing.
4️⃣ Excellent gum compatibility
Zirconia is biocompatible and less likely to cause gum discoloration or inflammation.

⚖️【Comparison with Other Materials】
Silver fillings (metal alloy): Covered by insurance and less costly, but less aesthetic and may cause metal allergies.
Ceramic inlays: Highly aesthetic, but not as strong as zirconia.
Zirconia inlays: A well-balanced option combining both strength and aesthetics.

💡【Points to Note】
This is a self-pay treatment, so costs are higher compared to insurance-covered options.
Due to its high strength, in some cases there is a risk of wear on the opposing tooth.

🌸【Summary】
Zirconia inlays are especially recommended for those who:
✅ Want a strong, long-lasting material
✅ Prefer a natural appearance without silver fillings
✅ Are concerned about metal allergies
They are an excellent option for maintaining both dental health and a beautiful smile.
