Dental crowns are one of the most common and effective solutions for restoring damaged, decayed, or worn-down teeth. Designed to cover and protect, a dental crown can restore function, improve appearance, and last 10 to 15 years—or even longer with proper care.

But here’s the catch: how long your crown lasts depends significantly on your daily habits. What you do (or don’t do) each day can either extend its life or cause it to fail prematurely.

In this article, we’ll break down the good habits that preserve your crowns and the bad habits that can destroy them, so you can protect your investment and enjoy a healthier smile for years to come.

🦷 What Is a Dental Crown?

A dental crown is a custom-made cap placed over a damaged or weakened tooth. It can be made of:

  • Porcelain or ceramic (most natural-looking)
  • Porcelain-fused-to-metal (PFM)
  • Gold or metal alloys
  • Zirconia (high strength, durable)

Crowns are used for:

  • Strengthening cracked or worn-down teeth
  • Protecting a tooth after a root canal
  • Covering a dental implant
  • Improving tooth shape, alignment, or appearance

Though they’re designed to be durable, crowns are not indestructible—especially if daily care is neglected.

🔴 Daily Habits That Can SHORTEN the Life of Your Dental Crowns

❌ 1. Skipping Brushing and Flossing

While the crown itself doesn’t decay, the natural tooth underneath still can. Bacteria and plaque can collect at the gumline and around the edges of the crown, causing:

Pro tip: Use a soft-bristled toothbrush and fluoride toothpaste. Don’t forget to floss around the crown daily!

❌ 2. Teeth Grinding (Bruxism)

Nightly teeth grinding or jaw clenching puts intense pressure on dental crowns. Over time, this can cause:

  • Cracks or fractures in the crown
  • Loosening or dislodgement
  • Jaw pain or headaches

Solution: Ask your dentist about a custom nightguard if you grind your teeth.

❌ 3. Chewing Hard Foods or Non-Food Items

Dental crowns are strong—but they’re not made for chewing:

  • Ice
  • Hard candies
  • Popcorn kernels
  • Fingernails
  • Pen caps

These habits can chip, crack, or break a crown, especially porcelain or ceramic ones.

❌ 4. Using Your Teeth as Tools

Don’t open packages, bottles, or tear tags with your teeth. This can not only break the crown but also damage your jaw alignment.

❌ 5. Ignoring Gum Health

Crowns rely on strong gum support. If gum disease develops, it can:

  • Cause the gums to recede
  • Expose the tooth root or crown margin
  • Lead to tooth and crown failure

Inflamed or bleeding gums are a warning sign. Make sure you keep up with cleanings and dental checkups.

❌ 6. Eating Sticky or Sugary Foods in Excess

Sugary or sticky foods (like taffy or caramel) can:

  • Pull crowns loose
  • Increase risk of decay at the crown margin
  • Create acidic environments that damage nearby teeth

✅ Daily Habits That Can EXTEND the Life of Your Dental Crowns

✔️ 1. Maintain Excellent Oral Hygiene

This one’s obvious—but essential. Brushing and flossing twice daily is your best defense against:

  • Plaque buildup
  • Gum disease
  • Crown failure due to underlying decay

Consider using:

  • A water flosser for better cleaning around crowns
  • Antibacterial mouthwash to reduce plaque and inflammation

✔️ 2. Visit Your Dentist Regularly

Routine checkups (every 6 months) allow your dentist to:

  • Inspect your crown for cracks or wear
  • Check the health of the tooth underneath
  • Clean hard-to-reach areas to prevent issues

Early detection can prevent small problems from becoming expensive repairs.

✔️ 3. Wear a Nightguard if You Grind

A custom-fit nightguard protects both natural teeth and dental restorations from the grinding force while you sleep. It’s a small investment that can save you thousands in crown replacements.

✔️ 4. Watch Your Diet

Include foods that promote oral health:

  • Crunchy veggies (carrots, celery)
  • Cheese and yogurt (rich in calcium)
  • Leafy greens
  • Water (to rinse away acids)

Avoid excessive consumption of acidic drinks (soda, citrus juice), which can weaken the enamel around the crown.

✔️ 5. Avoid Smoking or Tobacco

Smoking impacts your gum health and can lead to bone loss around teeth and implants. This increases the chances of crown failure over time.

✔️ 6. Be Gentle with Your Mouth

  • Don’t bite into extremely hot or cold foods right after crown placement (to avoid thermal sensitivity).
  • If your crown feels “off” or painful, don’t wait—get it checked.

🧠 Bonus Tip: Know the Signs of a Failing Crown

Keep an eye out for:

  • Pain or sensitivity near the crowned tooth
  • Visible crack or chip in the crown
  • Loose feeling or movement when chewing
  • Bad odor or taste (sign of bacteria under the crown)

If you notice any of these signs, contact your dentist immediately. Prompt attention can often save the crown and prevent more serious problems.

Dental crowns are an excellent solution for restoring function and appearance—but they require your daily cooperation to stay in top shape.

By avoiding bad habits and adopting protective ones, you can:

  • Extend the life of your crown well past the average
  • Reduce the need for costly repairs or replacements
  • Maintain healthy gums and surrounding teeth

Treat your crown like a valuable investment—because that’s exactly what it is.
