The duration before consuming food following a dental restoration varies depending on the type of filling material used. Traditionally, with amalgam (silver) fillings, a period of approximately 24 hours was advised to allow the material to fully harden and achieve its optimal strength. Composite (white) fillings, conversely, typically harden immediately under a curing light during the dental procedure.
Adhering to recommended waiting times, when necessary, prevents potential damage to the new restoration. Prematurely applying excessive pressure from chewing could lead to chipping, displacement, or general weakening of the filling. This, in turn, can compromise the filling’s longevity and effectiveness in protecting the treated tooth from further decay. Historically, the development of faster-curing materials has reduced or eliminated waiting periods, enhancing patient convenience.
