Common Causes of Dental Crown Damage and How to Avoid Them

A dental crown isn’t just a cosmetic fix—it’s a powerful tool for restoring function, protecting fragile teeth, and bringing back your natural smile. But without proper care, even the strongest crown can fail. In this guide, discover the main reasons crowns break or wear down and learn how to protect your investment with smart, simple habits.

What Is a Dental Crown and Why Is It Needed?

This is a tooth-shaped cap that fits over a damaged or weakened tooth. It’s used when a tooth has a large cavity, is cracked, worn down, or has had a root canal. Think of it as a shield—protecting your tooth so you can bite, chew, and smile without worry.

Reasons someone might need a crown:

• Protect a tooth after root canal treatment
• Restore a tooth that has cracked or chipped.
• Cover a large filling when there isn’t much tooth left.
• Make the shape or color of a tooth better.
• Strengthen a worn-down tooth.

Crowns are made from different materials like porcelain, metal, or zirconia. A durable dental crown should last many years, but it still needs attention and care.

Common Causes of Dental Crown Damage

Even the strongest crown isn’t invincible. Several things can cause it to crack, chip, or come loose. Here’s what to watch out for.

Teeth Grinding and Clenching (Bruxism)

Clenching or grinding your teeth during the night time can place a huge amount of pressure on your crown. Eventually, this stress can cause the crown to crack or wear down faster. You might not even know you’re doing it unless your jaw feels sore in the morning or your partner hears the grinding sounds.

Look out for:

• Morning headaches
• Jaw tension
• Flattened or chipped teeth

Chewing Hard Foods or Objects

It’s tempting to crunch on ice or chew a pen cap, but these habits can break a crown. Even biting into hard candy or a nut can cause trouble if your crown isn’t strong enough to take the pressure.

Avoid:

• Ice cubes
• Hard candies
• Fingernails
• Pens and pencils

If you enjoy crunchy snacks, chew with care and use your back teeth.

Poor Oral Hygiene and Decay

Just because a crown covers a tooth doesn’t mean it’s safe from cavities. If food and bacteria collect where the crown meets the gum, it can lead to decay underneath. This can result in the crown to become loose or fall out completely. Good brushing and flossing keep this from happening. If you’re not cleaning around the crown, you’re leaving your tooth open to damage.

Remember to:

• Brush twice each day
• Floss daily, especially around the crown edges
• Rinse after meals when you can

Trauma or Accidental Injury

A sudden hit to the mouth—during sports or even from a fall—can crack or knock a crown loose. If you play contact sports or ride bikes, always wear a mouthguard.

To prevent damage:

• Wear a custom-fit sports guard
• Avoid rough play
• Get dental checkups after any facial injury.

A fast visit can help repair dental crown damage early before it becomes a bigger issue.

Improper Crown Placement or Design

If a crown isn’t shaped or fitted correctly, it can cause trouble from day one. You might feel discomfort, bite problems, or pressure that leads to damage. That’s why it’s important to go to an experienced local dentist or dentist in Vancouver who knows how to place crowns with precision.

Natural Wear and Tear Over Time

Nothing lasts forever—not even crowns. Daily chewing, biting, and brushing wear them down slowly. Over the years, dental crown damage from regular use has become more likely, even with excellent care. Depending on the material, most crowns last 10–15 years.

Signs it’s time for a new crown:

• Loose fit
• Visible cracks
• Gum irritation
• Changes in bite feel

How to Prevent Damage to Your Dental Crowns

Good habits and regular care can help your crown last longer and stay in great shape.

Maintain Excellent Oral Hygiene

Keep your crown clean to avoid decay and gum trouble. Use a soft-bristled brush and non-abrasive toothpaste.

Daily care checklist:

• Brush morning and night
• Floss gently under the crown edge
• Use fluoride mouthwash

Ask your dentist near you for tips on cleaning tools that work best around crowns.

Avoid Habits That Stress Your Teeth

Your teeth—and your crowns—aren’t built for breaking things or crunching on hard objects. Stop those small habits that can add up to big problems.

Cut out:

• Nail biting
• Opening packages with your teeth
• Ice chewing

Attend Regular Dental Visits

Your dentist can identify small issues before they turn into serious damage. Catching problems early means faster, simpler fixes.

Routine checkups help:

• Spot cracks or weak spots
• Catch signs of decay.
• Adjust the bite if needed.

If you are from the area and want to get a dental crown in Vancouver, schedule cleanings twice a year. It’s the right way to keep your crown and your natural teeth healthy.

When to See Your Dentist

Don’t wait for pain. See your dentist if:

• Your crown feels loose
• You spot a crack or chip.
• You feel soreness around the crown.
• Your bite feels off

Quick action can save your crown—and sometimes your tooth.
