Opalescence

Opalescence is a globally recognized professional tooth whitening brand, credited with pioneering the modern dentist-supervised whitening industry. Introduced in 1990, the brand gained fame for its patented sticky, viscous gel formula that stays in place in custom-fitted trays, allowing for more effective and comfortable treatments compared to previous liquid-based methods.

The brand is owned and manufactured by Ultradent Products, Inc., an American dental supply company. Its products are widely distributed to dental practices worldwide and are known for offering various concentrations of carbamide peroxide and hydrogen peroxide, often including potassium nitrate and fluoride (PF) to reduce tooth sensitivity. The product line has expanded over decades to include pre-filled trays, whitening toothpastes, and in-office "boost" treatments.
