Why do the gums bleed around my crown in Glen Iris?

After getting a crown attached to your tooth, you might notice sore, red gums that bleed while brushing or flossing. This isn’t normal—and it may indicate underlying problems needing professional attention.


Common Reasons for Gum Inflammation Around Crowns

1. Poor Crown Fit
A poorly fitting crown can trap food and bacteria, making it difficult to clean and leading to gum inflammation and decay under the crown. These hidden pockets become hotspots for infection and gum disease.

2. Biologic Width Violation
When the crown edge extends too far beneath the gum or invades the biologic width, the body’s immune system reacts, triggering persistent gum inflammation.

3. Root Canal Abscess
A faulty root canal treatment can trap bacteria in the tooth’s root. This may lead to pain, infection, and swelling or abscess in the bone around the crown.


Consequences of Untreated Crown-Related Gum Problems

  • Chronic gum swelling and redness

  • Easy bleeding during oral care

  • Persistent bad breath and taste

  • Bone loss and tooth decay

  • Tooth sensitivity and even tooth mobility

Left untreated, these complications can endanger both your crown and your natural tooth, sometimes leading to extensive dental intervention.


What Should You Do?

If you’re experiencing bleeding, pain, or swelling around a crown, seek a dental evaluation. Only a dentist can pinpoint the cause and offer solutions, such as adjusting the crown, treating infection, or prescribing a deep cleaning.

Addressing these concerns quickly prevents advanced gum disease and damage to your restoration.
