Can Porcelain Crowns Get Decayed? Causes and Effective Treatments

Are Porcelain Crowns Prone to Decay?

However, while the porcelain crown remains intact, the underlying natural tooth structure can still be vulnerable. In some cases, decay may form on the prepared tooth beneath the crown due to:

• Cavities or dental disease not being fully treated before the crown procedure.

• A poor fit between the crown and the natural tooth, creating small gaps where food and bacteria accumulate.

• Improper oral hygiene that allows bacteria to thrive around the crown’s margins.
  

How to Treat Tooth Decay Under Porcelain Crowns

1. Remove the crown to access and clean the affected tooth.

2. Treat the decayed tissue thoroughly.

3. Restore the crown, or replace it with a new one to protect the tooth and restore aesthetics.

In advanced cases, an X-ray may be used to determine the extent of damage and plan further treatment. This approach helps prevent progression of decay and reduces the risk of tooth loss.

Preventing Decay After Porcelain Crowns

• Follow a healthy diet: Reduce sugar intake, avoid tobacco and stimulants, and limit overly hard or chewy foods that could compromise crown durability.

• Maintain strong oral hygiene habits:

  • Brush at least twice daily with a soft-bristled toothbrush.

  • Use dental floss or an interdental cleaner to remove trapped food particles.

  • Rinse with salt water or an antibacterial mouthwash to control bacteria.

• Schedule regular dental check-ups: Visiting the dentist every 6–12 months allows for early detection of problems, professional cleaning to remove tartar, and long-term crown protection.
