You may have tried over-the-counter teeth whitening products, such as strips, trays, and toothpaste, to no avail. The results are only temporary. This can be frustrating, but there is a better way: Zoom teeth whitening. This professional teeth bleaching procedure is done in the dentist’s chair. It uses 25% hydrogen peroxide whitening, along with a Zoom Advanced Power Chairside Lamp that accelerates the bleaching process.
