ICON® Resin Infiltration

White spots can make otherwise healthy-looking teeth appear uneven in color. They may become noticeable after orthodontic treatment or develop because of changes in the tooth enamel, and depending on the cause, these areas can be difficult to improve with conventional whitening alone.

‍

At MacArthur Dental Arts in Irvine, CA, ICON resin infiltration offers a minimally invasive approach for certain types of white spot lesions, penetrating porous areas within the enamel with a specialized resin to help reduce the visible contrast with the surrounding tooth.

‍

What Causes White Spots on Teeth?

‍

One common cause is enamel demineralization, in which lost minerals leave affected areas more porous and noticeably whiter. White spot lesions may also become visible around orthodontic brackets when plaque accumulates in hard-to-clean areas, and certain developmental enamel conditions or dental fluorosis can produce a similar appearance. Because different conditions can look alike, your dentist will evaluate the affected teeth before recommending treatment.

‍

A No-Drill Treatment Option

‍

Instead of covering the affected area with a restoration, the ICON resin is applied to the porous enamel, allowed to penetrate it, and then hardened in place. This changes the way light passes through the enamel, which may reduce the contrast between the white spot and the surrounding tooth. Because healthy tooth structure does not need to be removed to create space for a filling or veneer, ICON does not require conventional drilling or, in most cases, local anesthesia for appropriate lesions.

‍

ICON After Orthodontic Treatment

‍

White spot lesions can sometimes become noticeable after braces are removed, particularly when plaque accumulated around orthodontic brackets caused enamel demineralization. ICON resin infiltration may provide a conservative treatment option for certain post-orthodontic white spots, though your dentist will evaluate the enamel to confirm the affected areas are suitable for infiltration.

‍

ICON vs. Veneers and Bonding

‍

Bonding adds composite resin to the tooth surface to change its shape or cover an imperfection, and veneers cover the visible surface of a tooth with a custom-made restoration. ICON works within the porous enamel itself rather than simply covering the white spot, which can help preserve more of the tooth's natural structure. The best treatment depends on the cause and characteristics of your white spots and your overall cosmetic goals.
