MD Aesthetics teeth whitening is a simple and hassle-free system designed to be part of your evening brushing routine. A unique gel formula containing hydrogen peroxide is painted on using a professional whitening pen once at bedtime for 2-3 weeks. Results are noticeable almost immediately and maximum effects realized after completing the full treatment course. Liquid Smile is 3x stronger and 4x faster than store-bought whiteners and eliminates the night-time wearing of expensive trays. On average, clients repeat the process every 6-12 months for ongoing teeth whitening. Visit our location during business hours to purchase your teeth whitening pen.
