How long can you wear a temporary crown?

Temporaries serve a specific clinical role: they protect the prepared tooth, maintain occlusal space, and give the patient function while the permanent restoration is being fabricated. Standard bis-acryl provisionals handle normal occlusal load for 4 to 6 weeks without significant wear. PMMA-milled provisionals, produced through a digital workflow, can extend reliable service to 3 months in full-arch or complex restorative cases where the treatment timeline demands it.

For general dentists managing single-unit or multi-unit crown cases, the turnaround at the lab sets the outer boundary for how long any temporary needs to perform. When a lab ships final restorations within 10 to 12 business days, a standard bis-acryl provisional is more than adequate. Delays push risk onto the provisional and onto the patient relationship. Predictable lab turnaround is not a convenience item; it is part of the clinical risk management picture.

For prosthodontists coordinating full-arch rehabilitations, the provisional itself is a diagnostic tool, used to confirm vertical dimension, phonetics, and esthetic parameters before the final ceramic is committed. In those cases, the temporary may intentionally run 6 to 12 weeks. That extended wear demands a milled PMMA provisional with verified occlusion, not a chairside pour. The lab that mills the final restoration should ideally be part of that provisional planning conversation from the start.
