In 2022, my dentist replaced a crown for my upper right incisor, which had a root canal on it in 2015. Since that time, the crown has come off four times. Although my dentist re-cements it each time, the crown doesn’t feel secure. The crown most recently fell off in November, but I anticipate it happening again since it feels loose. It’s so inconvenient. Will I need a new crown soon? I don’t think my insurance will cover any of it because this one is only two years old. – Thanks. Maggie from OH
Maggie,
When a new dental crown dislodges, it is likely due to an issue with the initial crown preparation. This may involve insufficient retention form, particularly when significant tooth structure is lost following root canal treatment.
A post in a damaged tooth, followed by composite buildup, can help retain a crown
A common approach for the issue involves:
- Intracanal Post Placement: A dentist inserts a flexible post into the root canal to provide additional support and strengthen the weakened tooth structure.
- Core Build-up: The dentist places composite resin material over the post, restoring the tooth’s form and creating a more stable foundation for the crown.
This approach aims to enhance retention by utilizing both the remaining tooth and reinforced internal structures.
The success of this procedure depends on how much tooth structure remains. A dentist will recommend alternative treatment in cases with minimal remaining tooth structure.
