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

The recommended waiting period of 5 days before performing restorative work after tooth whitening is based on the need to allow the teeth to stabilize after the whitening process. Tooth whitening, especially those involving carbamide or hydrogen peroxide, can temporarily increase the porosity of the enamel and dentin, which means that certain materials used in restorative work, such as composites, might not bond optimally if applied too soon.

During this period, any residual effects of the whitening agents subside, and the teeth return to a more stable pH and moisture level. This stability is crucial for ensuring successful adhesion and longevity of restorative materials, which otherwise might be compromised if applied immediately after the whitening treatment. Therefore, waiting approximately 5 days helps to ensure the success of any subsequent restorative procedures and the overall health of the tooth structure.
