How to remove bad odor from porcelain-fused-to-metal dental crowns

To eliminate this odor, it is important to maintain good oral hygiene habits, including brushing teeth, using dental floss, and rinsing with mouthwash daily to clean the teeth and periodontal tissues. Regular professional teeth cleaning and check-ups at the dental clinic are recommended to promptly remove dental calculus and plaque, preventing bacterial growth. Additionally, using fluoride toothpaste and oral disinfectants may help reduce the odor. If the bad smell persists, it is advisable to visit a dentist for evaluation, as you may need to replace porcelain crowns or undergo other treatments.
