Chipped Tooth Crown: Understanding the Causes, Treatment Options, and Long-Term Care

A chipped tooth crown can be both alarming and painful—but it’s not uncommon, and more importantly, it’s treatable. Whether it happens from biting into something hard, an old dental crown giving way, or trauma to the mouth, a chipped dental crown is a situation that calls for quick, informed action. The key is understanding why it happens, what to do next, and how to prevent further issues.

This article provides a comprehensive, updated, and easy-to-understand guide to chipped tooth crowns—whether porcelain, metal, ceramic, or composite—explaining causes, immediate responses, professional solutions, and how to protect your oral health in the long run. If you’ve ever wondered what to do if your crown chips, this guide has you covered.

What Is a Chipped Tooth Crown?

A chipped tooth crown refers to a fracture, crack, or break in an artificial cap (crown) that is placed over a natural tooth. Crowns are commonly used in dentistry to:

Restore broken or worn teeth
Protect weak teeth after a root canal
Improve the appearance of discolored or misshaped teeth
Anchor dental bridges

When a crown chips, the integrity of the restoration is compromised. Depending on the severity, a chipped crown might simply need smoothing, partial repair, or complete replacement.

Common Types of Dental Crowns and Their Susceptibility to Chipping

Understanding what kind of crown you have is essential in assessing the risks and appropriate treatment options.

Type of Crown	Material Used	Appearance	Durability	Chipping Risk Level
Porcelain-fused-to-metal (PFM)	Porcelain over metal	Tooth-colored exterior	Moderate to High	Moderate
All-Ceramic or All-Porcelain	Ceramic, Zirconia	Very natural-looking	Moderate	High
All-Metal	Gold or metal alloys	Metallic finish	Very durable	Low
Resin	Composite resin	Natural color	Least durable	Very High
E-max or Zirconia	High-grade ceramic	Superior aesthetics	High durability	Low to Moderate

Causes of Chipped Tooth Crowns

Several causes can lead to crown damage, most of which are preventable. Recognizing the cause is the first step to preventing recurrence.

Trauma or Injury
- A fall, blow to the face, or sports injury can crack or chip a crown.
Biting Hard Substances
- Ice, popcorn kernels, or hard candies are among the common culprits.
Bruxism (Teeth Grinding)
- Grinding or clenching, especially during sleep, wears down crown material over time.
Natural Wear and Tear
- Crowns aren’t permanent; over time, even strong materials degrade.
Poor Bonding
- Inadequate cementation during crown placement can weaken its adhesion and structural stability.
Thermal Stress
- Extreme temperature changes (e.g., eating hot soup and then drinking cold water) can expand and contract crown material, leading to cracking.
Underlying Tooth Decay
- If the tooth beneath the crown decays, it can destabilize the crown, making it more vulnerable to chipping.

Symptoms That May Accompany a Chipped Crown

Sometimes a chip is visually obvious. Other times, it may be subtle but still harmful. Be aware of:

Sensitivity to hot or cold
Pain while biting or chewing
A jagged edge you can feel with your tongue
Gum irritation or swelling near the crown
Bad taste or odor, possibly indicating infection

What To Do Immediately If Your Crown Chips

If your crown chips, the first step is to stay calm and take the following precautions:

Remove Loose Pieces
- If the chip is large or loose, remove it carefully to avoid swallowing or inhaling it.
Rinse and Store
- Rinse your mouth with warm salt water to avoid infection. Store any broken piece in a clean container if it may be useful for your dentist.
Avoid Chewing on That Side
- Reduce further damage or pain by chewing on the unaffected side.
Use Dental Wax or Temporary Filling
- Available at most pharmacies, dental wax can cover sharp edges and prevent tongue irritation.
Schedule a Dental Appointment Immediately
- Even if it doesn’t hurt, don’t wait. Early repair avoids more serious problems.

Treatment Options for a Chipped Tooth Crown

The ideal treatment depends on the extent of the damage and the type of crown involved.

Minor Chip or Hairline Crack

If it’s superficial and not causing pain:

Polishing or Smoothing: Dentist reshapes the crown’s rough edge.
Dental Bonding: Composite resin fills the chip to restore function and appearance.

Moderate Chip

If a portion has broken off but the underlying tooth is unaffected:

Resin Patching: For ceramic or porcelain crowns, resin can temporarily patch the chip.
Crown Resurfacing: Sometimes, only the outer layer needs replacement.

Major Fracture or Loss of Function

If the crown is cracked through or affects your bite:

Crown Replacement: The most common solution; the old crown is removed, and a new one is fabricated.
Core Buildup or Post Placement: If the underlying tooth is damaged, a buildup or post is done before crown replacement.

Crown Fell Off with Tooth Damage

Root Canal Therapy (if needed)
Extraction (in severe decay)
Implant Placement (if the tooth is beyond saving)

How Dentists Diagnose and Assess Chipped Crowns

Visual Examination
X-rays to assess the health of the tooth underneath
Bite Test to ensure alignment hasn’t been compromised
Thermal and Pressure Tests if sensitivity or nerve issues are suspected

Crown Materials and Their Repairability

Crown Material	Repairability	Common Repair Approach	Long-Term Durability Post-Repair
Porcelain-Fused Metal	Moderate	Composite bonding	Moderate
All-Porcelain	Low	May require full replacement	Low to Moderate
Metal	High (but rarely chips)	Buffing or reshaping	High
Resin	High but temporary	Composite patching	Low
Zirconia	Moderate	Surface bonding	High

Can a Chipped Crown Be Left Untreated?

Technically yes, but it’s not recommended. Even small chips can:

Compromise bite alignment
Lead to gum irritation or infections
Allow bacteria to enter and damage the underlying tooth
Result in worsening cracks or complete crown failure

Delaying treatment could turn a minor fix into a major dental procedure.

How Much Does It Cost to Repair or Replace a Chipped Crown?

Type of Treatment	Average Cost (USD)	Notes
Minor Resurfacing	$100 – $250	Quick in-office procedure
Resin Bonding	$150 – $400	Temporary or cosmetic
Full Replacement	$800 – $2,500	Depends on material
Root Canal + Crown	$1,500 – $3,000	If nerve damage is involved
Dental Implant	$3,000 – $5,000	For irreparably damaged tooth

Insurance may partially cover crown repair or replacement if medically necessary.

Preventing Future Crown Chipping

Wear a Night Guard
- Especially if you grind your teeth
Avoid Hard and Sticky Foods
- Ice, nuts, and caramel can strain your crown
Regular Dental Checkups
- Small cracks can be caught early
Good Oral Hygiene
- Brushing and flossing around the crown prevent decay
Mindful Habits
- Don’t use your teeth to open packages or bottles

Chipped Crown vs. Chipped Natural Tooth

It’s essential to differentiate the two. Sometimes, the chipped edge might belong to your natural tooth underneath, not the crown. Dentists use X-rays and probing to identify the true source.

Feature	Chipped Crown	Chipped Natural Tooth
Material Appearance	Ceramic or metal look	Translucent natural enamel
Pain Sensitivity	Often minimal	Sharp pain or sensitivity
Repair Method	Crown repair/replace	Filling, bonding, or crown

FAQs

Can I eat with a chipped crown?
Avoid eating until your dentist examines the chip. Chewing can worsen the damage or cause pain.

Is it a dental emergency?
Not always, but any chipped crown should be treated as time-sensitive. Delay can lead to infection or deeper cracks.

How long should a dental crown last?
A properly cared-for crown lasts 10–15 years, but some materials like gold or zirconia can last over 20 years.

Can a chipped crown be repaired at home?
No. While dental wax can protect soft tissues temporarily, professional repair is essential to maintain tooth integrity.

Will insurance cover a chipped crown?
Most dental plans cover crown repair or replacement if it’s medically necessary and not caused by patient negligence.
