What is the recommended waiting period after whitening treatment before replacing defective restorations?

The recommended waiting period of 5 days after whitening treatment before replacing defective restorations is based on the chemical processes that occur in teeth after whitening. During whitening, the teeth undergo changes in their internal structure and the pH balance may shift temporarily. To ensure that the color of the natural teeth stabilizes and any residual effects of the whitening agents have diminished, waiting for around 5 days is optimal.

This allows for the release of oxygen from the whitening agents to come to a conclusion, thereby reducing the risk of mismatch in color between the newly restored areas and the adjacent natural tooth structure. The timing allows dental materials used in restorations to bond effectively and ensures that the final aesthetic appearance is satisfactory and stable.
