Can Teeth Grinding Break Crowns?

Yes. Dental crowns are designed to be strong and durable, but they are not indestructible. Over time, the excessive forces created by grinding and clenching can damage crowns, loosen restorations, and even affect the natural teeth supporting them.

Are Dental Crowns Strong?

Absolutely.

Modern dental crowns are made from durable materials designed to withstand normal chewing forces.

However, grinding and clenching create forces that are often much greater than those experienced during everyday eating.

Repeated excessive pressure can eventually damage even well-made restorations.

Can Grinding Damage a Crown?

Yes.

Although crowns are designed to protect weakened teeth, grinding may increase the risk of:

• Chipped porcelain
• Cracks in the crown
• Wear of the chewing surface
• Loosening of the crown
• Damage to the tooth underneath

Not every patient who grinds will experience these problems, but the risk is higher when excessive bite forces are present.

Can Grinding Damage Other Dental Work?

Yes.

Grinding doesn’t affect only crowns.

It can also contribute to:

• Broken fillings
• Chipped bonding
• Damaged veneers
• Worn implant restorations
• Cracked natural teeth

Because grinding affects your entire bite, we evaluate all of your teeth and restorations—not just the area that’s causing symptoms.

Can the Tooth Under the Crown Crack?

Unfortunately, yes.

A crown protects a tooth, but it cannot eliminate the forces created by grinding.

If excessive pressure continues over time, the natural tooth beneath the crown may still develop a crack or fracture.

This is one reason we often recommend protecting your teeth with a custom nightguard if signs of grinding are present.

How Do I Know If Grinding Is Damaging My Crowns?

Signs may include:

• A chipped crown
• Pain when biting
• A loose crown
• Increased tooth sensitivity
• Repeated crown repairs or replacements
• Worn teeth in other areas of your mouth

Sometimes there are no obvious symptoms, and the earliest signs are identified during a routine dental examination.

Can a Nightguard Protect My Crowns?

Often, yes.

A custom nightguard creates a protective barrier between your upper and lower teeth while you sleep.

Although it usually doesn’t stop grinding, it helps reduce the stress placed on:

• Crowns
• Natural teeth
• Fillings
• Veneers
• Dental implants

Protecting your restorations today may help reduce the need for more extensive treatment in the future.

How Do We Evaluate Bite Forces?

At Total Dentistry, we don’t simply replace a damaged crown.

We also evaluate:

• Signs of grinding or clenching
• Tooth wear
• Bite function
• Existing restorations
• Cracked teeth
• Jaw muscles

Understanding why a restoration failed helps us recommend treatment that supports your long-term oral health.

Our Total Oral Health Approach

At Total Dentistry, every restoration is part of a larger system.

Healthy teeth, healthy gums, and a healthy bite all work together to support the long-term success of crowns and other dental restorations.

If excessive bite forces are contributing to damage, addressing those forces is just as important as repairing the restoration itself.

The Bottom Line

Dental crowns are extremely durable, but they are not immune to the effects of grinding and clenching.

If you grind your teeth, protecting your crowns with a custom nightguard may help reduce excessive wear and prolong the life of both your restorations and your natural teeth.

If you’ve noticed a chipped crown, repeated crown damage, or signs of teeth grinding, contact Total Dentistry to schedule an examination. We’ll evaluate your bite and recommend the best way to protect your smile for years to come.
