Poor oral hygiene is a leading cause of cavities under a crown. Once a crown is placed, patients often think all is done now and they don’t bother to maintain good oral hygiene by regular tooth brushing, flossing, and oral rinses.
All dental procedures are at risk of failure if oral hygiene is compromised. You must play your part for good results after dental treatment.
- Other causes of cavities under the crown include:
- Poor crown design
- Poor tooth preparation before crown placement
- Excessive pressure on crown leading to cracks (bruxism)
