What should I do if the natural tooth under a porcelain-fused-to-metal crown starts hurting?

When the natural tooth under a porcelain crown experiences pain, the first step is to determine the cause of the pain, as it may result from tooth sensitivity, dental caries, apical periodontitis, or other factors. Depending on the specific cause, different treatments can be implemented: 1. Tooth Sensitivity: Sensitivity may occur due to the removal of part of the enamel during the placement of the porcelain crown. It is recommended to use toothpaste designed for sensitive teeth and avoid excessively hot or cold foods. If symptoms persist, seek professional dental care for possible root canal treatment. 2. Dental Caries: If the underlying tooth supporting the porcelain crown develops decay, the affected dental hard tissue should be promptly removed and treated with dental fillings or root canal treatment. In some cases, it may be necessary to remove the porcelain crown for proper restoration. 3. Apical Periodontitis: An X-ray examination can help assess the condition of the tooth root and surrounding tissues. After diagnosis, root canal treatment or pulp revascularization may be performed to eliminate inflammation and restore tooth function. When experiencing pain in the natural tooth beneath a porcelain crown, prompt dental consultation is advised to identify the cause and implement appropriate treatment measures.
