Can a porcelain-fused-to-metal crown be done?
Disease description:
I have a tooth that's severely damaged, and my dentist said I can get a porcelain crown. However, I'm a bit concerned. Is getting a porcelain crown really reliable? Could it develop problems after just a few years of use?

In general, porcelain-fused-to-metal crowns (PFM) can be used.
Porcelain-fused-to-metal crowns, also known as metal-ceramic crowns, are ideal restorations. They consist of a metal base made from an alloy, with low-fusing porcelain powder applied on the surface to simulate natural teeth. The restoration is then fired and fused in a high-temperature vacuum porcelain furnace. These crowns offer excellent biocompatibility and are safe for implantation in the body or for long-term use in the oral cavity.
Porcelain crowns are suitable for treating tooth wear, discoloration, mild malposition, cracks, or structural defects. If a patient has severe dental caries, periodontal disease, or occlusal problems, appropriate treatment must be performed first to ensure oral health and stability before considering porcelain crown restoration. Additionally, porcelain crowns may also be used for aesthetic purposes, such as correcting excessive spacing between teeth or improving the shape of anterior teeth. Patients should have detailed discussions with their dentists before undergoing porcelain crown restoration to jointly develop the most suitable treatment plan.
In daily life, it is recommended to promptly remove food debris. Try to avoid consuming high-sugar and high-acid foods such as candies and carbonated beverages, which can erode tooth enamel and potentially lead to dental caries.
