Dental crowns are prosthetic restorations designed to cover and support weakened or damaged teeth. They play an essential role in maintaining oral function by restoring a tooth’s strength, shape, size, and appearance. By protecting vulnerable teeth, they contribute to both dental health and aesthetics.
Custom-made to fit each patient, dental crowns are crafted from materials that vary in durability and appearance. From metal and porcelain to a combination of both, each option offers specific benefits for diverse dental needs. With proper care, they can last for many years, though their lifespan also depends on the crown type and the patient’s oral health.
In this blog, we will explore a common question, ‘How long do dental crowns last?’ We will look at the factors that affect the durability of these restorations, including oral hygiene habits and lifestyle choices. We will also share tips on how to care for them to help extend their longevity.

Factors Affecting Dental Crown Longevity
Answering the question, ‘How long do dental crowns last?’ requires an understanding of the key factors that influence their lifespan, including:
- Materials Used:
The choice of material plays a significant role in the crown’s lifespan. For instance, metal crowns are stronger and more resistant to wear, making them ideal for back teeth. In comparison, porcelain crowns are suited for visible teeth due to their natural appearance, but they require more careful maintenance to avoid damage. - Oral Care Habits:
Proper oral hygiene helps extend a crown’s lifespan. Through consistent brushing, flossing, and mouthwash use, you can lower the risk of decay and plaque buildup that can compromise the treatment. - Dietary Choices:
Limiting sugary drinks like sodas helps protect the crown by reducing the risk of decay. Also, avoiding hard foods like nuts and sticky foods like caramel prevents damage by reducing the risk of cracking or loosening the crown. - Lifestyle Habits:
Certain habits can shorten the lifespan of a dental crown. For example, smoking leads to gum disease, while grinding places excessive pressure on the crown, potentially causing cracks or wear. - Regular Dental Visits:
Routine dental check-ups help detect issues early and prevent damage. They allow your dentist to monitor the condition of the crown and address any concerns before they compromise its longevity.
By paying attention to these factors, patients can maintain their crowns for as long as possible.
The Importance of Proper Care and Maintenance
Proper care and maintenance are key to extending the lifespan of a dental crown. A consistent routine of brushing and flossing helps prevent plaque buildup and damage. Regular dental check-ups are also essential to monitor the crown’s condition and address any issues early.
Along with good oral hygiene, patients should be mindful of their food and drink choices. Hard or sticky foods like ice or gum can damage the crown, so avoiding them is important. Additionally, habits like teeth grinding or jaw clenching can wear down the crown, but wearing a custom night guard can protect it during sleep.
Dental Crown Materials and Their Lifespan
Dental crowns are made from various materials, each offering distinct benefits and lifespans, such as:
- All-Porcelain:
This material provides a natural appearance, making it ideal for front teeth. However, it is less durable than other options and can be more prone to chipping or cracking. - Porcelain-Fused-to-Metal (PFM):
PFM crowns combine the aesthetic appeal of porcelain with the strength of a metal base. The downside is that the metal layer may become visible over time, affecting appearance. - All-Metal:
Metal crowns are highly durable and resistant to wear, making them suitable for molars. The main drawback is their metallic appearance, which does not blend with natural teeth. - Zirconia:
Zirconia crowns offer exceptional strength and a natural appearance. While they are highly durable, they can sometimes cause wear on opposing teeth due to their hardness.
Understanding the advantages and disadvantages of each material helps patients select the option that matches their needs and preferences.
Common Causes of Dental Crown Failure
Dental crowns, though durable, can fail due to factors affecting both the crown and the original tooth, requiring replacement. Below are common causes of dental crown failure:
- Poor Oral Hygiene:
Neglecting regular brushing and flossing can lead to decay around the crown, weakening its bond to the tooth. - Dental Injuries:
Accidents or trauma to the mouth can cause a crown to crack, chip, or become loose. - Material Failure:
Over time, the material of the crown can wear down or break, especially with heavy use. - Crown Construction Issues:
Improper fitting or poor placement can lead to early crown failure. - Crowned Tooth Condition:
If the underlying tooth is weakened or decayed, it can affect the crown’s lifespan and function.
Signs That Your Dental Crown Needs to Be Replaced
Dental crowns can show signs of failure with prolonged use. Here are some indicators that it’s time to replace them:
- Discolouration:
Staining or darkening around the crown can indicate decay or material breakdown. - Decay:
The area around the crown may show signs of tooth decay or damage, which could affect the crown’s fit. - Cracks or Chips:
Physical damage to the crown, such as cracks or chips, may compromise its integrity. - Looseness:
A crown that feels loose or moves can indicate issues with the cement or the underlying tooth. - Pain or Sensitivity:
Pain around the crown or sensitivity to hot and cold can signal problems with the crown or tooth.
Regular visits to the dentist help catch these signs early, allowing for timely dental crown replacement if needed.
The Role of Your Dentist
Dental professionals play an important role in the success of dental treatments, particularly when it comes to placing dental crowns. Their skills and experience contribute to the restoration’s longevity and functionality, helping patients maintain healthy smiles. Here’s what they do:
- Assessing Your Oral Health:
The dentist evaluates the tooth’s location, your bite pattern, and your aesthetic preferences to recommend a suitable restoration material. - Recommending the Appropriate Material:
Based on your needs, they select from materials like porcelain, metal, or zirconia. - Proper Installation:
They carefully prepare both the tooth and crown to achieve a secure and long-lasting fit. - Aftercare Guidance:
They advise on how to maintain the crown and avoid any potential damage following the dental crown procedure.
Maximising Dental Crown Longevity
Taking care of your dental crown is essential to promote its longevity and maintain the overall health of your smile. Below are some simple practices to protect your investment and avoid the need for premature replacements:
- Practise Good Oral Hygiene Habits:
Brush twice a day, floss daily, and use mouthwash to keep the crown and surrounding teeth clean. - Avoid Dental Injuries:
Be mindful of activities that could damage the crown, such as chewing on hard objects like pens or ice. - Seek Prompt Dental Care:
Regular dental check-ups help detect any issues early and allow for timely intervention. - Limit Sugary or Acidic Foods:
Foods like candies or lemons can erode the crown material and contribute to decay.
By following these guidelines, you can maximise the lifespan and preserve the appearance of your dental crown.
Dental Crown Longevity: What to Expect
If you’re wondering, ‘How long do dental crowns last?’ These dental restorations can remain functional for many years. Some may even endure for decades. Here’s an overview:
- Zirconia Crowns:
These usually last between 5 and 15 years. - Porcelain Crowns:
Their average lifespan is between 5 and 10 years. - Full Metal Crowns:
These can last anywhere from 3 to 15 years. - Porcelain-Fused-to-Metal Crowns:
