Do Crowns Fall Out Easily?

June 24, 2024

Dental crowns are a fantastic restoration option for teeth that are cracked, broken, severely decayed, or have undergone root canal treatment. They offer superior strength, aesthetics, and longevity compared to fillings. But a common concern patients have is: Do crowns fall out easily?

Like most things in dentistry, the answer is not a simple yes or no. While crowns are designed to be very durable, there are situations where they can become loose or even fall out. At Arlington Dental Excellence, we understand your worries, and this blog post aims to shed light on what to expect with your crown and how to maximize its lifespan.

How Long Do Dental Crowns Last? 

Dental crowns can last for many years with proper care and maintenance – often exceeding 10 to 15 years. However, several factors can influence their longevity:

  • The type of crown material: Porcelain fused to metal (PFM) crowns are generally quite durable. All-ceramic or all-porcelain crowns offer a more natural look but may be more susceptible to chipping or breaking, especially in the back teeth.
  • The placement of the crown: Molars and premolars, used for chewing, experience greater stress and may require replacement sooner than front teeth.
  • Your oral hygiene habits: Brushing twice daily, flossing regularly, and maintaining a healthy diet all contribute to the tooth's health under the crown and the longevity of the restoration.
  • Underlying dental issues: If you have bruxism (teeth grinding) or a habit of chewing on hard objects, your crown may be more prone to damage or loosening.

Signs That Your Crown Might Be Loose

Here are some signs to watch out for that might indicate a loose crown:

  • Sensitivity or pain around the crowned tooth, especially when chewing.
  • A feeling of looseness or a slight gap around the crown.
  • Difficulty biting or chewing.
  • Discomfort or a gritty sensation when biting down.

So, Do Crowns Fall Out Easily? 

The short answer is no; crowns don't fall out easily. However, it's not entirely impossible. Several factors can influence a crown's stability; in some cases, they may become loose or dislodged.

Causes of Dental Crowns to Loosen or Fall Out 

Here are some of the most common reasons why a crown might become loose:

  • Improper fit: During the crown placement process, a dentist ensures the crown fits precisely over the prepared tooth. If the fit isn't ideal, it can create space for bacteria to accumulate, leading to decay and potential loosening of the crown.
  • Everyday wear and tear: Chewing, especially on hard foods, can put stress on the crown over time. This can wear down the cement that holds it in place, eventually leading to loosening.
  • Bruxism (teeth grinding): If you grind or clench your teeth at night, the excessive pressure can cause the crown to become loose or even crack.
  • Trauma: An accidental blow to the mouth, such as from a fall or during sports, can dislodge a crown.
  • Poor oral hygiene: Plaque buildup around the crown can weaken the bond between the crown and the tooth, increasing the risk of loosening and decay.

How to Prevent Your Dental Crown from Falling Out? 

Here are some key steps you can take to ensure your crown lasts for as long as possible:

  • Practice excellent oral hygiene: Brush your teeth twice daily for two minutes each time, and floss daily. This removes plaque and food particles that contribute to decay.
  • Maintain a healthy diet: Limit sugary and acidic foods that erode your teeth and the crown material.
  • Avoid chewing on hard objects: This includes ice, hard candy, nutshells, and other items that can put undue stress on your crown and teeth.
  • Wear a mouthguard: If you grind your teeth at night, a mouthguard can protect your crown and teeth from damage caused by bruxism.
  • Schedule regular dental checkups: Regular dental appointments allow your dentist to monitor the condition of your crown and address any potential problems early on.


While dental crowns are designed to be durable and long-lasting, various factors can influence their stability. By understanding these factors and taking preventive measures, you can help ensure the longevity of your dental crowns and minimize the risk of them falling out easily.

Can flossing loosen a crown?

Regular flossing around and between your dental crown is imperative for maintaining its integrity. Neglecting to floss regularly can lead to recurrent decay, potentially compromising the crown's stability. Ensure you gently slide the floss down between the teeth, using an up-and-down motion, while carefully maneuvering it against the side of the tooth and beneath the gums.

How do you protect your teeth when the crown falls out?

You have several choices: opt for wax, use a piece of gauze, or buy temporary dental cement. Since the tooth's nerves and tissue will be exposed, making them more susceptible to decay, it's recommended that you refrain from eating or chewing on that side of your mouth until your crown is properly secured.

Can you get an infection if your crown falls out?

Even if your natural tooth and the surrounding gums aren't causing discomfort, the delicate area remains vulnerable to breakage, potentially escalating the risk of infection and necessitating a root canal. Even in the absence of pain following a crown falling out, it's crucial to promptly schedule an appointment with a dentist to address the issue.
