Crowns 101: How to Know When Your Tooth Needs One

If you’ve ever been told you “might need a crown,” you probably had a few questions.
What exactly does a dental crown do? When is it truly necessary? And how do you know if it’s the right option for your smile?

At Williams, Daily & Frazier Dental in Raleigh, NC, we want you to feel confident, not confused, when it comes to your dental care. This guide breaks down the basics of dental crowns, when you might need one, and how they can protect your teeth for the long haul.

What Is a Dental Crown, Exactly?

A crown is a custom-made cap that covers the entire visible portion of a tooth, restoring its shape, strength, and appearance. Crowns are designed to look and function just like natural teeth, blending seamlessly into your smile.

They're typically made from:

• Porcelain or ceramic (great for front teeth)
• Metal alloys (strong and durable for molars)
• Porcelain-fused-to-metal (a blend of strength and aesthetics)

Think of a crown as armor for a damaged tooth, it protects what’s underneath while giving you full chewing power and a natural appearance.  It’s important to choose the right one for your lifestyle and take care of them well.

When Does a Tooth Need a Crown?

Crowns aren’t just for cosmetic fixes. They serve a critical role in preserving and protecting teeth that are weakened or at risk of further damage. Here are the most common reasons we recommend a crown:

1. Large Cavity or Filling

When a tooth has a large cavity, or an old filling that takes up most of the tooth, there may not be enough healthy structure left to support another filling. A crown helps hold everything together and prevent cracks.

2. Cracked or Broken Tooth

Whether it’s from biting down on something hard, a sports injury, or teeth grinding, cracks can compromise your tooth’s integrity. A crown provides stability and protects the crack from spreading.

3. After a Root Canal

Root canal-treated teeth are more brittle and prone to breakage. Placing a crown helps seal the tooth and restore strength.

4. Tooth Wear or Erosion

Teeth that have worn down from grinding (bruxism) or acid erosion can become shorter and more sensitive. A crown rebuilds the shape and function of these teeth.

5. Cosmetic Enhancements

In some cases, crowns are used to improve the appearance of misshapen or severely discolored teeth.

If any of these sound familiar, schedule an exam with our team. We’ll evaluate your tooth and help you decide if a crown is the right move.

How Do I Know If I Need One Now?

Here are a few signs your tooth may need a crown:

• Ongoing sensitivity to heat or cold
• Pain when chewing or biting
• A chipped, cracked, or broken tooth
• A tooth that feels weak or “hollow”
• Visible damage or darkening around a large filling

Even if your tooth isn’t currently painful, damage can worsen over time. The earlier we address it, the more likely we can save the tooth and avoid more intensive treatment down the road.

What to Expect During a Crown Procedure

At Williams, Daily & Frazier Dental, we make the crown process smooth and comfortable.

How It Works:

1. Initial evaluation: We take digital X-rays and assess your tooth.
2. Tooth preparation: We gently shape the tooth to make space for the crown.
3. Impressions: We take precise digital or physical impressions to create your custom crown.
4. Temporary crown: You’ll wear a temporary crown while your permanent one is being made.
5. Final placement: At your next visit, we’ll bond the crown to your tooth and make sure it fits comfortably.

With proper care, a dental crown can last 10–15 years, or even longer.

Crown vs. Filling: What’s the Difference?

A common question we get is: Why can’t I just get another filling?

Fillings work well for small areas of decay or damage. But once a tooth is significantly weakened, a filling may not provide enough support. Fillings fill, crowns protect.

If you’re not sure which you need, we’re happy to talk you through the pros and cons of each option.

How to Care for a Crown

Good news: taking care of a crown is just like taking care of your natural teeth.

• Brush twice a day with a fluoride toothpaste
• Floss daily, especially around the crown’s edges
• Avoid chewing on hard objects (like ice or pens)
• Keep up with your checkups for cleanings and exams

We’ll keep an eye on the crown’s condition and the health of the tooth beneath it at every visit.
