How Often Do Crowns Need to be Replaced? – Identifying Factors

Dental crowns are an excellent solution for reinforcing teeth that are missing or damaged. 

However, they do have a specified lifespan, even with the best care, and will eventually need to be replaced. 

On average, dental crowns can last anywhere between 10 to 15 years, depending on the material you choose for the crown and how well they are maintained. To determine if it’s time for a replacement, it’s best to consult with your dentist. 

Material of the Crown 

The material used to make a dental crown significantly affects its durability and lifespan. 

Porcelain Crowns: Typically last between 10 to 15 years 

Ceramic Crowns: Last between 10 to 15 years.

Metal Crowns: Last 15 to 20 years or more. 

Resin Crowns: Last about 5 to 10 years. 

Quality of the Initial Dental Work 

Poorly done dental work the first time can lead to problems such as gaps, which may cause decay or loosen the crown over time. If the crown is not fitted correctly or if there are issues with the tooth preparation, the crown may not do its job properly. 

Oral Hygiene Practices 

Good oral hygiene can play a major role in preventing plaque buildup and decay around the crown. If plaque accumulates, it can lead to gum disease and cavities, which can affect the crown and the underlying tooth, thereby requiring more frequent replacements. 

Diet & Lifestyle Factors 

Consuming hard or sticky foods can put undue stress on crowns, leading to potential damage or loosening. Similarly, a diet high in sugary or acidic foods can contribute to decay around the crown. 

Teeth Grinding (Bruxism)

Grinding or clenching your teeth can place significant stress on crowns, causing them to crack or wear down more quickly.

Dental crowns are inherently designed to protect the tooth they cover. If a crown can no longer serve this protective role, it should be replaced. Keeping a damaged or infected crown in place can lead to serious oral complications and may require more extensive dental work.

For instance, if a cavity develops beneath a crown, your dentist will need to remove the crown to treat the decay, or the infection may progress deeper into the tooth. Ignoring the problem could even result in the need for a root canal, which is more complex than simply replacing the crown.

Whether your crown has cracked from chewing on candy or it’s been in place for many years, it’s important not to delay necessary treatment to avoid more severe issues in the future.

While crowns are designed to last, you may want to think about scheduling an appointment with your dentist if you notice any of the following signs. 

• Your crown has visible damage or cracks.
• You experience swelling, discomfort, or pain around the crowned tooth. 
• You notice extreme wear and tear in your crown. 
• Your crown is damaged. 
• Your crown is loose. 
• Your crown is no longer aesthetically boosting your smile. 
• Your gum line is receding. 
• Your bite seems uneven or abnormal.
• Your tooth is decaying under the crown. 

• Brush your teeth twice daily with fluoride toothpaste and floss every day to prevent plaque buildup around your crown.
• Avoid consuming hard foods such as ice, nuts, and hard candies, as well as sticky items like caramel and taffy, as these can damage or loosen your crown.
• If you grind your teeth or clench your jaw, especially at night, wear a mouthguard to protect your crowns from excessive pressure and wear.
• Schedule regular dental check-ups and cleanings. Your dentist can monitor the condition of your crown and address any issues before they become serious.
• If you notice any changes in your crown, such as discomfort, loosening, or visible damage, contact your dentist promptly to avoid further complications.
• Reduce your intake of sugary and acidic foods and beverages, which can contribute to tooth decay and damage the area around your crown.
• Eating a balanced diet with plenty of fruits, vegetables, and whole grains can promote overall oral health and help keep your crowns in good condition.
• If you’re getting a new crown, discuss material options with your dentist to select a high-quality material that suits your needs and lifestyle, ensuring greater durability and longevity.

Dental crowns are an effective restoration treatment for safeguarding your teeth from damage and decay. While they do require periodic replacement, they are both reliable and long-lasting.
