- The typical recommended duration for wearing at-home bleaching trays can vary depending on the concentration of the bleaching agent and the specific product instructions.
- However, it generally ranges from 30 minutes to overnight.
- This flexibility allows for customization based on individual sensitivity and desired whitening results. Wearing the trays for too short a time, such as 5 to 10 minutes, may not be effective, while excessively long durations, like 48 hours continuously, can lead to gum irritation and tooth sensitivity.
- A moderate duration of 2 to 4 hours is sometimes recommended but is product-dependent.

- Therefore, the most common and safe range advised by dental professionals is from 30 minutes up to overnight wear, ensuring optimal whitening while minimizing side effects.
