What is the recommended waiting period before performing restorative work after tooth whitening?

The correct answer is a waiting period of 5 days before performing restorative work after tooth whitening. This recommendation is based on the impact that various tooth whitening products, especially those that contain hydrogen peroxide or carbamide peroxide, have on the tooth structure and the overall health of the enamel.

During the whitening process, the bleaching agents penetrate the enamel and dentin, creating a temporary state where the teeth may be more porous and susceptible to changes in hydration and bonding characteristics. Over time, as the teeth stabilize after whitening, they regain their normal characteristics, making them more suitable for restorative procedures.

Restorative materials, such as composites or bonding agents, adhere best to a stable tooth surface. Performing restorative work too soon after tooth whitening could compromise the bond strength due to the residual effects of the whitening agents. Waiting about 5 days allows for the majority of the hydrogen or carbamide peroxide to dissipate and ensures that the tooth is in a more stable state, enhancing the longevity and effectiveness of the restorative work.

In contrast, the options of waiting immediately after whitening, only 1 day, or 2 weeks do not align with the established guidelines observed in dental practice. An immediate restoration could lead to complications, while a longer waiting period than necessary might delay treatment
