A dental crown—commonly called a dental cap—can last for many years. But like everything else in life, it doesn’t last forever. While modern crowns are durable and reliable, they are still subject to wear, damage, and aging.
Many patients walk into Royal Oral & Dental Clinic, Kanpur, unaware that their old crown is failing. Ignoring the warning signs of a damaged or loose dental cap can lead to pain, infection, or even tooth loss.
In this guide, we’ll help you understand the early symptoms of a failing dental crown, what causes them, and what to do next.
What Is a Dental Crown?
A dental crown is a tooth-shaped cap placed over a damaged, decayed, or root canal-treated tooth to restore its shape, strength, and appearance. Crowns are made from various materials like
- Porcelain
- Ceramic
- Zirconia
- Metal alloys
- Porcelain-fused-to-metal (PFM)
While crowns can last 10–15 years (or longer with proper care), they are not permanent. Over time, they may wear down, become loose, or cause discomfort.

Warning Signs Your Dental Cap May Be Failing
It’s important to know the red flags before the issue becomes a dental emergency. Here are the top signs your crown might be in trouble:
1. Recurring Pain or Sensitivity
Pain when you bite down or sensitivity to hot or cold drinks could indicate:
- Decay underneath the crown
- A hairline crack in the cap
- An improperly fitted crown
📍If discomfort persists, consult a dentist immediately to avoid nerve damage.
2. Crown Feels Loose or Wobbly
A healthy crown should feel as solid as a natural tooth. If it moves or wiggles:
- The cement holding it may have deteriorated
- Bacteria can seep under and cause decay
3. Swelling or Bleeding Around the Crown
Gum irritation is a serious sign of:
- Inflammation
- Gum disease
- Poor crown margin fit
Red, swollen gums near the crown should never be ignored.
4. Bad Breath or Unpleasant Taste
A failing crown may trap bacteria, leading to:
- Infection
- Bad odor
- Metallic or sour taste in the mouth
🦷 This often means there’s decay beneath the crown or the surrounding tooth.
5. Visible Crack or Damage
If your crown has a chip or visible crack, it could:
- Affect your bite
- Allow bacteria to enter
- Lead to sharp edges that irritate your tongue
6. Receding Gums Around the Crown
Gum recession exposes the crown edges or underlying tooth root, often resulting in:
- Increased sensitivity
- Higher decay risk
- Aesthetic concerns (especially with front teeth)
Why Do Dental Crowns Fail?
Here are some common causes of crown failure:
- Improper fitting during initial placement
- Poor oral hygiene over time
- Tooth grinding (bruxism)
- Injury or trauma to the crown
- Natural wear and tear
What Should You Do If Your Dental Cap Is Failing?
Don’t panic—but don’t delay either. Here’s what to do:
✅ 1. Book a Dental Evaluation Immediately
Only a professional can assess the damage and recommend solutions.
✅ 2. Avoid Sticky or Hard Foods
Until your crown is fixed, avoid chewing on the affected side.
✅ 3. Maintain Good Oral Hygiene
Brush gently around the crown and floss to prevent plaque build-up.
