what is a white patch?
Our enamel is a mineral that develops in an orderly way, forming a crystalline structure.
Disturbances during enamel development affects this order and an irregular crystalline structure is formed. The optical properties are then altered and the white patch appears a chalky white as the irregular enamel crystals scatter reflected light different to the rest of the enamel.
This is very common and is called enamel hypoplasia or hypomineralisation.
how to remove the white patch
Up until recently the only treatment available was to drill it away and cover it with a white filling.
ICON resin infiltration works by opening up pores within the white patch, allowing resin to infiltrate and fill in the spaces.
Light can then smoothly pass through the white patch without scattering and allow the desired translucent properties to return.
