Temporary dental crowns protect modified teeth while permanent crowns are being crafted. They can safeguard you from dental sensitivity, tooth decay, and shifting teeth during treatment. Temporaries are typically composed of either stainless steel or acrylic and are made to last only a few weeks, whereas permanent crowns are designed to last 10 years or more. These restorations are bonded in place using provisional dental cement, which is easier to remove during a follow-up appointment.
