**Teeth whitening brand** [**Opalescence**](https://opalescence.com/?ref=packaging-europe.ghost.io) **has introduced pre-filled Opalescence Go Advanced whitening trays, said to remove the need for an outer placement tray and reduce packaging waste.**

The company states that each patented UltraFit tray is pre-filled with whitening gel to ensure consistent distribution and precise placement during treatment, with a one-step application process. The trays are available in 15% hydrogen peroxide concentration with a Cool Mint flavour.

Opalescence adds that the trays are ‘clinically proven’ to whiten teeth by up to 5 shades and Opalescence Go Advanced whitening has been designed by dentists to be gentle on teeth.

Opalescence Whitening’s Chief Clinical Officer, Dr. Jaleena Fischer-Jessop, comments: “My patients want fast, long-lasting, at-home teeth whitening they can trust and use safely while still getting top-tier results,” says Opalescence Whitening’s Chief Clinical Officer, Dr. Jaleena Fischer-Jessop. “By pairing the UltraFit tray with our advanced whitening formula, we’re offering a straightforward, effective, and convenient way to brighten smiles.”
