An early weakened spot on a tooth is called an incipient lesion. It is not yet a cavity, needing to be filled, but, if left alone, more than likely will slowly progress to the point of needing a restoration in the form of a filling.
Icon is a process that uses infiltration technology to fill and reinforce demineralized enamel without drilling or anesthesia.....and without unnecessary loss of healthy tooth structure.
It can also be used to treat those blotchy, white spots that some of us have on our teeth that are cosmetically less than ideal.
Fluoride is used as a preventative agent................Icon is used as an infiltrative agent...............composite is used as a restorative agent.
