Teeth can become up to 8 shades whiter in approximately 45–60 minutes of chair time.
Furthermore, the technology has evolved to address patient comfort. Earlier iterations of whitening lights generated significant heat, which could lead to pulpal inflammation and post-operative sensitivity. Modern Zoom Activators utilize LED (Light Emitting Diode) technology, which produces minimal heat. This is a crucial distinction; by minimizing the thermal load on the tooth pulp, the Activator helps reduce the risk of the dreaded "zingers" or sharp sensitivity often associated with professional whitening. Additionally, the Activator features adjustable intensity settings, allowing clinicians to tailor the treatment to patients with specific sensitivity thresholds, thereby balancing efficacy with patient comfort. activator zoom dental
