A temporary crown serves as a protective covering for a tooth that has been prepared for a permanent crown. It acts as a placeholder, shielding the underlying tooth structure from external factors while the permanent crown is being fabricated in a dental laboratory. It ensures the tooth remains functional and aesthetically acceptable during the interim period.
Purpose of a Temporary Crown
Its primary function is to protect the prepared tooth from damage and bacterial contamination, as the tooth structure is more vulnerable after preparation. It also helps prevent sensitivity to temperature changes or pressure, which can occur when the dentin, the layer beneath the enamel, is exposed. Beyond protection, the temporary crown maintains the correct spacing between teeth, preventing adjacent teeth from shifting into the prepared area, ensuring the permanent crown will fit properly. It helps preserve the tooth’s appearance and chewing function, allowing individuals to continue their daily activities with minimal disruption until the final restoration is placed.
The Placement Process
The process of placing a temporary crown begins after the natural tooth has been prepared. This preparation involves reshaping the tooth by removing enamel and dentin, creating a suitable foundation for the crown. An impression of the prepared tooth is then taken, often using a mold or a digital scanner. This impression serves as a blueprint for the dental laboratory to craft the permanent crown.
A temporary crown is fabricated, often chairside. It is typically made from a resin or acrylic material that can be quickly molded and cured. The dentist ensures the temporary crown fits snugly and the bite feels comfortable and natural. Finally, the temporary crown is secured with a temporary dental cement, which holds it in place but allows for easy removal later.
Caring for Your Temporary Crown
Proper care ensures a temporary crown remains intact until the permanent crown is ready. Avoid chewing on hard or sticky foods like nuts, ice, or caramels, as these can dislodge or crack the temporary crown. Shifting chewing to the opposite side of the mouth can also reduce stress on the temporary crown.
Maintain oral hygiene around a temporary crown, which requires a gentle approach. Brush carefully, using a soft-bristled toothbrush to clean the area without dislodging the crown. When flossing, slide the floss out from between the teeth rather than pulling it upwards, which could lift the temporary crown.
Mild sensitivity to hot or cold is common, but persistent or severe pain requires a call to the dental office. If a temporary crown becomes loose, cracked, or falls off, contact your dentist immediately. They can advise if it needs recementing or replacement to protect the underlying tooth. Prompt attention prevents complications and ensures the tooth remains healthy until the permanent crown appointment.
Transition to the Permanent Crown
The final step involves removing the temporary crown and placing the permanent one. During this appointment, the dentist removes the temporary crown and cleans any remaining cement from the prepared tooth.
The permanent crown is then placed onto the tooth. The dentist checks the fit, bite, and shade to ensure it blends seamlessly with the surrounding teeth. Adjustments are made as needed for comfort and aesthetics. Once satisfied, the permanent crown is securely bonded into place with durable dental cement, completing the restoration.
