A white patch may have been present since the tooth appeared, become noticeable after braces, or developed more recently. It can relate to enamel development, mineral changes, or other surface conditions. Colour alone cannot tell whether the area is stable, active, shallow, deep, or structurally damaged. That distinction matters before choosing a product intended to make the mark less visible.
At Cookstown Dental Centre, we review the history and examine the tooth surface before discussing treatment. Some spots need prevention and monitoring, while others may be considered for a selected cosmetic approach. This page covers the broader diagnosis and options; resin infiltration is only one possible method for suitable lesions. The plan should explain what is being treated, what improvement is realistic, and how any underlying risk will be managed.
