fluoride varnish

Fluoride varnish is a sticky, liquid substance applied to the surface of teeth to help protect them from decay. When brushed onto the teeth, it hardens quickly and releases fluoride, which strengthens tooth enamel—the outer layer that shields teeth from cavities. It’s a safe and effective preventive treatment often used in dental offices, especially for children, but also suitable for adults. Regular application can help reduce the risk of cavities, promote healthier teeth, and restore early signs of decay. The process is quick, painless, and typically requires no rinsing afterward.
