Final answer:
Chewing on amalgam immediately after placement is not permitted due to its strength.
Step-by-step explanation:
The statement is False. Unlike composite resin restorations, chewing on amalgam immediately after placement is not permitted because of its greater strength. While amalgam is generally stronger than composite resin, it still needs time to fully harden and set in the mouth. Chewing on amalgam too soon can damage or dislodge the filling, causing it to fail.
