ICON RESIN INFILTRATION (ICON) IN SAN FRANCISCO

What is ICON?

Resin infiltration is a minimally invasive treatment designed to address white-spot lesions (WSLs) and certain congenital hypocalcified enamel defects ("hypo spots"). WSLs typically result from enamel porosities caused by an imbalance between demineralization and remineralization due to poor oral hygiene, plaque, bacteria, and acids.

Over time, the outer enamel remineralizes, preventing calcium and other ions from reaching the deeper layers, halting the progression of the lesion. The white appearance of these lesions occurs because light scatters at the demineralized enamel’s subsurface. Hypo spots, or enamel bruising, are congenital defects that often result from trauma or infection affecting primary teeth.

The Procedure

  • Single visit treatment

  • No shots or numbing required

  • No drilling involved

  • Teeth are cleaned with plain pumice

  • Lesions are etched for 3×2 minutes to remove the outer remineralized layer that blocks ion access

  • Finishing bur used to smooth any areas that don't show improvement

  • Drying agent (ethanol) applied

  • Resin infiltrant is applied and allowed to soak in for 3 minutes (via capillary action)

  • Excess material is removed using cotton rolls, micro-brushes, and floss

THE BENEFITS

  • Less Invasive & Affordable: Unlike fillings or veneers, ICON doesn’t involve drilling or tooth removal, making it more cost-effective and conservative.

  • Early Treatment Option: Can be performed at a younger age, whereas cosmetic treatments like veneers often require full dental development.

  • Natural Whitening of Hypo Spots: Treated areas blend better with natural enamel and respond well to whitening, unlike untreated spots that may worsen.

  • Prevents Progression of Decay: By sealing the enamel surface, ICON stops white spots from developing into full-blown cavities.

  • Long-Lasting Cosmetic Results: Once applied, the resin creates a stable, smooth appearance that enhances smile aesthetics for years.

WHAT TO EXPECT DURING ICON TREATMENT

The ICON procedure is efficient, precise, and well-tolerated by children. Here’s what it involves:

  • Painless Preparation: Teeth are cleaned and etched to remove the outer enamel layer blocking access to deep spots.

  • Resin Soak & Seal: A drying agent is applied, then the resin is soaked into the enamel for deep infiltration and light-cured.

  • Second Application: A second coat of resin ensures complete coverage, followed by polishing for a smooth, natural finish.

  • Quick Recovery: Treatment lasts 45 minutes to 1 hour, with no downtime or sensitivity afterward—just immediate visual improvement.

FREQUENTLY ASKED QUESTIONS

Have questions about ICON Resin Infiltration? Here are helpful answers for parents:

  • These are visible white marks caused by enamel demineralization or developmental defects. They often result from poor hygiene or early trauma.

  • Nope! ICON is entirely pain-free. There are no needles, no drills, and no anesthesia—just gentle application and light curing.

  • The entire treatment takes about 45 minutes to 1 hour, depending on the number of teeth treated and the size of the lesions.

  • ICON seals and stabilizes the affected enamel. While good oral hygiene is still important, results are long-lasting and can significantly reduce future discoloration.

  • Yes! ICON is a minimally invasive and clinically proven treatment that’s perfectly safe for kids with enamel defects or early white-spot lesions.
