What is a proprietary mouthwash?

A proprietary mouthwash is a commercially developed oral rinse that is owned and marketed by a specific company, often featuring unique formulations or ingredients that distinguish it from generic or store-brand alternatives. These mouthwashes may offer specific benefits, such as whitening, plaque removal, or breath freshening, and are typically protected by trademarks or patents. Their effectiveness and safety are often supported by research conducted by the manufacturer.
