What minimally invasive procedure is used to treat small interproximal lesions or post-orthodontic white spots?

Resin infiltration is a minimally invasive procedure specifically designed to address small interproximal lesions and post-orthodontic white spots. This technique involves the application of a low-viscosity resin that penetrates the porosities of early caries or demineralized enamel. By sealing these areas, it not only halts the progression of decay but also restores the aesthetic appearance of the affected teeth.

The benefit of resin infiltration lies in its conservative nature; it preserves more of the natural tooth structure compared to other techniques. Traditional treatments, such as composite restorations, typically require more extensive removal of healthy tooth material, making resin infiltration a preferred choice for early lesions.

This approach also requires minimal preparation and can be performed without the need for anesthesia, which is advantageous in many clinical situations. Its efficacy in treating early detection lesions gives it a notable place in modern dental care.
