When you get a tooth crown, you might wonder, “How long does a tooth crown last?” A crown is designed to protect and strengthen your tooth, but like most things, it won’t last forever. However, you can increase its longevity by following good oral hygiene and necessary precautions.
Let us explore “how long does a tooth crown last” and what factors affect its longevity.
What is a Tooth Crown?
A tooth crown is like a cap that fits over the tooth to restore its size, shape, strength, and appearance. Crowns are used to protect teeth that have been broken, severely decayed, or have had large fillings. A crown keeps the tooth intact, helps in proper functioning, and also improves its
functioning.
When Do You Need Dental Crowns?
Dental crowns are often necessary when a cavity becomes so large that it requires a root canal, leaving a significant portion of the tooth missing. However, there are many other situations where a crown might be needed, including:
- A broken tooth
- Severe tooth damage
- A misshapen tooth
- To support a dental bridge
- Tooth fractures
How Long Does a Tooth Crown Last on Average?
On average, a tooth crown lasts between 10 to 15 years. However, with good oral hygiene and regular visits to the dentist for dental check-ups, some crowns can last up to 20 years or more.
How long a tooth crown lasts depends on many factors, including the material used (such as porcelain, metal, or ceramic), how well you care for your teeth, and habits like teeth grinding or chewing on hard objects
What Factors Affect the Lifespan of Tooth Crown?
Several factors influence how long a tooth crown lasts. Here are the key factors:
Material of the Crown
Porcelain or Ceramic Crowns:
These are popular for their natural appearance but can be less durable than metal crowns, especially on back teeth where biting forces are stronger. Its lifespan is 10-15 years.
Metal Crowns:
Gold and other metal crowns are highly durable and resistant to wear, and last longer than porcelain or ceramic crowns. Its lifespan is 20 years or more.
Porcelain-Fused-to-Metal (PFM) Crowns:
It has the strength of metal with the aesthetics of porcelain and offers a balance between durability and appearance. Its lifespan is 10 to 20 years.
Location of the Crown
Front Teeth:
Crowns on front teeth tend to last longer because they don’t have to handle as much pressure.
Back Teeth:
Crowns on back teeth, like molars and premolars, wear down more quickly over time.
Oral Hygiene Practices
Regular Brushing and Flossing:
Brushing and flossing regularly keep your mouth healthy by preventing decay around the crown.
Professional Cleanings:
Regular dental check-ups and cleanings also help keep the crowned tooth and surrounding areas in good shape.
Bite and Chewing Habits
Teeth Grinding (Bruxism):
Grinding your teeth can put too much pressure on a crown, making it crack or wear out faster.
Chewing on Hard Objects:
Chewing on hard things like ice, pens, or hard candies can also damage the crown and shorten its lifespan.
Quality of Crown Placement
Dental Expertise: The skill of the dentist in placing the crown plays a crucial role. A well-fitted crown is less likely to have issues like leakage or discomfort, which can affect its longevity.
Adhesive Quality: The type and quality of the dental cement used for bonding the crown to the tooth also affects longevity.
Signs That A Crown Needs Replacement
Signs that your crown may need to be replaced include:
Visible Damage:
Chips, cracks, or noticeable wear on the crown.
Discomfort or Sensitivity:
If you experience pain or sensitivity around the crowned tooth, it might indicate that the crown is not fitting properly.
