Sometimes, a tooth cap cracks, and it can leave you worried or uncomfortable. Many patients in Houston deal with this, and they often ask why it happens and what they can do to prevent it.
A tooth cap in Houston can stay in great shape when you understand what causes cracks and how to protect your restoration.
What Causes a Tooth Cap to Crack
1. Heavy Biting and Teeth Grinding
The most common causes of cracks are heavy biting and teeth grinding (also called bruxism). Many people grind their teeth at night without knowing it. This puts strong pressure on the cap and can lead to chips, lines, or breaks.
Grinding also affects the natural tooth under the cap. When both take too much pressure, cracks can form faster. If you grind your teeth, your dentist may see wear patterns, stress lines, or tight jaw muscles.
A tooth cap in Houston can handle normal chewing, but grinding makes the pressure too strong. A night guard can help protect your teeth if this is a problem for you.

2. Chewing Hard Foods Too Often
Many cracks in tooth cap happen when people chew foods that feel harder than expected. Ice, nuts, hard candy, and popcorn kernels can damage even strong dental restorations.
It’s easy to forget that a tooth cap isn’t unbreakable. While it looks like a natural tooth, it still needs care. Biting into hard objects creates small cracks first. Then those cracks grow with repeated pressure.
A tooth cap can stay strong when you choose foods that put less strain on your teeth.
3. Old Tooth Caps and Normal Wear Over Time
Every dental restoration has a lifespan. Many tooth caps last five to fifteen years, but some may wear down sooner depending on your habits and oral health. As a tooth cap gets older, the material may weaken. Small cracks form and slowly get bigger.
Daily chewing, temperature changes, and normal aging all affect your cap. If your tooth cap is older, your dentist may check it for early signs of cracks.
A new tooth cap made from modern materials stays more resistant to fractures and surface wear.
4. A Weak Tooth Under the Cap
When a tooth under the cap becomes weaker due to decay or stress, the cap may not have the support it needs, which can lead to cracks or looseness.
If decay forms under the cap, you may feel sensitivity or notice a change in how the cap fits.
5. Accidents or Sudden Impact
Biting your fork, getting hit in the mouth, or having a sports injury can crack a tooth cap instantly. Even a small impact can chip the edge or loosen the cap.
If this happens, it’s important to see your Houston dentist soon. Fixing a small crack early can stop a bigger break later.
Wearing a sports mouthguard helps prevent injuries if you play contact sports or have an active lifestyle in the city.
6. Temperature Changes
Hot things make it stretch, and cold things make it shrink. If temperature keeps changing fast like that, tiny cracks can start to form in your tooth and even in cap.
You might notice this if you sip hot cocoa and then drink ice water right after.
A tooth cap stays safer when you avoid sudden temperature swings during meals.

How to Prevent a Tooth Cap from Cracking
You can keep your cap strong by adding a few easy habits to your day. These steps help both the cap and the natural tooth under it.
- Use a night guard if you grind
A night guard takes the pressure off your teeth and protects your cap.
- Avoid chewing very hard foods
Choose softer foods so you don’t put too much strain on your cap.
- Keep your oral hygiene strong
Brush twice a day and floss daily to keep the tooth under the cap healthy.
- Visit your dentist regularly
Checkups help your dentist spot small cracks before they turn into bigger problems.
- Protect your teeth during sports
A mouthguard helps stop sudden hits from damaging your cap.

FAQs
1. How long does a tooth cap usually last?
A well-cared-for tooth cap can last ten to fifteen years or longer. Your habits and oral health play a big role.
2. Can I fix a cracked cap at home?
No. A cracked tooth cap needs a dentist for tooth cap repair or replacement. Home fixes don’t last and can make the damage worse.
3. Why does my tooth cap feel sensitive even if it’s not cracked?
You may have gum recession, a small cavity under the cap, or mild irritation. A dental check-up helps you find the exact cause.
