1. Improper crown shape causing gum irritation
The crown margin should be smooth, continuous, harmoniously shaped with the root, and tightly bonded. Margins that are too thick, too thin, rough, or with gaps will irritate gums, leading to swelling.
2. Improper indication management
Porcelain crowns should be placed on healthy, non-inflamed teeth or roots. If pre-existing gum inflammation or swelling persists, it can become chronic and difficult to resolve. Therefore, comprehensive periodontal treatment should be completed first to ensure full gum health before crown placement.
3. Improper Procedures
Damage to the gums. Dr. Ally explains that fabricating porcelain crowns requires specialized instruments, proper techniques, and strict adherence to all procedural precautions. Failure to retract the gums or lack of technical proficiency can easily injure the delicate gum tissue during the procedure, leading to subsequent redness, swelling, bruising, or darkening of the gums.
