In the vast majority of cases, an early carious lesion, also known as an incipient or white spot lesion, that is not treated and is simply "watched" will progress into a cavitated lesion requiring restorative treatment. Most fillings have a life expectancy of 10-15 years and require replacement when additional decay forms around the margins or the restoration breaks down. Treating early lesions with Curodont before they cavitate can help prevent the need for a lifetime of costly restorative work. Curodont can be especially beneficial for interproximal lesions that would require the removal of healthy tissue to address decay.
