Resin infiltration is a minimally invasive restorative treatment for post-ortho white-spot lesions (WSLs) and certain congenital hypocalcified enamel (“hypo” spots). It seems to provide an intermediary treatment modality between prevention and restorative therapy. The concept was introduced as a micro-invasive approach for the management of smooth surface and proximal non-cavitated carious lesions. Unlike whitening products, Icon resin infiltration is considering to be a long term treatment solution. Research shows stability for at least 2 years.   This is a treatment we offer to help fade the appearance of WSLs & hypo spots. We can not assure the spot will disappear completely, but in most cases it provides a significant cosmetic improvement in one simple, painless visit. Worse case scenario – there’s no change in appearance, but at least nothing irreversible or invasive has been done to the tooth.
