Dental crowns are one of the most common and reliable restorations in modern dentistry. Designed to strengthen and protect a damaged or weakened tooth, a crown can restore function, improve appearance, and last for years when properly placed and cared for. However, not all crowns live up to their potential. In fact, some fail sooner than expected, leaving patients frustrated and in need of further treatment.

At Star Dental Institute, we specialize in high-quality crown restorations and patient education—because understanding why crowns fail is the first step to making sure yours don’t.

Let’s take a closer look at the top five reasons dental crowns fail and how you can avoid these common pitfalls.

1. Poor Oral Hygiene

Just because a crown is artificial doesn’t mean it’s immune to decay. In fact, the natural tooth structure underneath a crown is still vulnerable to bacteria and plaque. If you neglect brushing and flossing, decay can develop at the margins of the crown, especially near the gumline, leading to crown failure and even root canal infections.

How to Avoid It:
Maintain excellent oral hygiene. Brush twice a day with fluoride toothpaste, floss daily (especially around your crowned tooth), and consider using an antibacterial mouthwash. Schedule professional cleanings and exams at Star Dental Institute every six months to keep your crowned teeth healthy and intact.

2. Improper Fit or Placement

A crown that doesn’t fit correctly can spell trouble from the start. If the crown is too loose, too tight, or poorly aligned, it can lead to bite issues, discomfort, or even early wear and tear. Gaps between the crown and the tooth can also harbor bacteria and food particles, increasing the risk of decay or gum disease.

How to Avoid It:
Choose an experienced dental team. At Star Dental Institute, we use advanced digital scanning and precision lab work to ensure a perfect fit for your crown. Our dentists take the time to evaluate your bite, tooth structure, and cosmetic goals before placement, so your crown feels natural and lasts.

3. Bruxism (Teeth Grinding)

If you grind or clench your teeth, especially at night, you’re putting significant stress on your crown. Over time, this pressure can cause the crown to crack, chip, or become loose. Bruxism is a common but often overlooked factor in crown failure.

How to Avoid It:
Talk to your dentist about any signs of grinding, like jaw pain, headaches, or worn teeth. If needed, we can fit you with a custom nightguard at Star Dental Institute to protect both your crown and your natural teeth while you sleep.

4. Trauma or Accidental Damage

Crowns are strong, but they’re not indestructible. Biting into hard foods (like ice, nuts, or hard candy), using your teeth as tools, or experiencing an injury can cause a crown to fracture or dislodge.

How to Avoid It:
Use common sense and caution. Avoid chewing on hard objects, and never use your teeth to open packaging. If you play contact sports, be sure to wear a custom athletic mouthguard to protect your dental work. And if you experience trauma to your mouth, schedule an appointment with us right away for an evaluation.

5. Failing to Address the Underlying Issue

Sometimes, a crown is placed without properly treating the tooth beneath it. If there’s an undetected crack, infection, or decay that isn’t resolved before the crown is placed, it can worsen over time and lead to failure. Additionally, gum disease around the crowned tooth can undermine the stability of the crown if left untreated.

How to Avoid It:
At Star Dental Institute, we don’t just cover problems—we correct them. Before placing a crown, our team ensures that the underlying tooth is clean, healthy, and structurally sound. We also assess the health of your gums and provide any necessary periodontal care beforehand to prevent complications down the line.

Signs Your Crown May Be Failing

It’s important to know the warning signs of crown failure so you can take action early. Watch for:

• Sensitivity or pain around the crowned tooth
• A loose or wobbly feeling
• Visible cracks or chips
• Gum recession or swelling near the crown
• Food gets stuck around the crown frequently

If you notice any of these symptoms, schedule a visit with Star Dental Institute as soon as possible. Early intervention can often save your crown and prevent more extensive treatment.

How Long Should a Crown Last?

With proper care, a high-quality dental crown can last anywhere from 10 to 15 years, sometimes even longer. The key is proactive maintenance, good oral hygiene, and working with a dentist who uses high-grade materials and cutting-edge technology.

At Star Dental Institute, we take pride in delivering crowns that not only look great but also stand the test of time.
