How Long Do PFM Crowns Last, on Average?
Average Lifespan of PFM Crowns
It's hard to imagine that, after several weeks of discomfort, you've just had a PFM crown placed on your tooth. While running your tongue over the smooth, shiny surface, you wonder, "How long will this thing last?" This question is one that many choose PFM crowns tried-and-true solution for durability and function.
While, on average, they can provide quality service for about 10 to 15 years, cases of much less frequent use exist, with records suggesting a lifetime of up to 20 years or even more with proper care. Thanks to a sturdy metal base with a porcelain overlay, PFM crowns are strong and look good, but their longevity depends on how well they are cared for.
Those Factors That Tend to Affect Longevity
A PFM crown is not one thing for others to regard. Individualized streams, however, tell the story:
- Oral Hygiene Practices: One must consider their crown as part of a multi-focus. Regular brushing and flossing together will defend against decay and gum diseases and, therefore, protect the foundation for that crown.
- Diet Choices: Every meal matters. Cheating on ice or sticky candies can crack or loosen a crown over time.
- Bruxism: If you are a bruxer, a teeth grinder by night, the pressure there could compromise the crown's longevity.
Many considerations affect the teeth, and chew a little harder each day. With this knowledge, individuals can further direct their efforts towards prolonging their lives, thus allowing for a thrilling list of restored smiles for years.
What Can Damage PFM Crowns?
Although the PFM crowns are meant to be strong, certain forms of daily habits and conditions can increase wear or lead to damage. Knowing about them can help you properly care for the crown and keep it going as long as possible.
Teeth grinding and clenching (Bruxism)
Consider this: Night after night, you grind away, unaware, whilst slumbering. Gradually, this sees the crown being subjected to intense pressure, with the possible effects leaving porcelain chipped or a weakened metal base over time. This same bruxism may become a more insidious culprit, thus ruining what would have otherwise been a lengthy lifespan for the crowns if it were not taken care of. A custom nightguard will act as a cushion in the way of grinding.
Poor Oral Hygiene
A PFM crown relies on the underlying tooth's and surrounding gums' health for support. If plaque builds up due to inconsistent brushing or flossing, it can lead to gum disease or decay around the edges of the crown. This weakens the bond between the crown and the tooth, making it more susceptible to damage or loosening.
Chewing Hard or Sticky Food
Eating hard-to-chew substances like ice or hard candy may feel good, but they indeed pose a risk to your PFM crown. This is because a crack may occur in the porcelain, or the adhesive supporting the crown might be damaged due to biting into an object of this nature. On the other hand, sticky foods like caramel may cause the crown to be tugged, pulled away from its place, and exert unnecessary pressure on it.
By eliminating the above causes of crown breakdown, you can keep your PFM crown in good condition and avoid costly repair or replacement.
How to Make Your PFM Crown Last Longer
Caring for the PFM crown helps to ensure its longevity. The life span can be significantly extended if one adopts the proper habits and carefully eliminates risks.
For Ensuring Oral Hygiene
- Brush your teeth with fluoride toothpaste at least twice daily to prevent decay at the edges of the crown.
- Floss daily to remove food debris and plaque below the gumline.
- Antibacterial mouthwashes most effectively control bacteria that lead to gum disease.
Diet Modifications
- Do not eat ice cubes, hard nuts, or candies that could crack your crown.
- Do not let soft, sticky foods like caramel or chewing gum pull the crown off.
- Increase the intake of tooth-friendly foods, such as milk, greens, and crunchy fruits and vegetables, that promote oral well-being.
Regular Dental Checkup
- Visit your dentist at an interval of six months to receive checkups and professional cleaning.
- If anything seems wrong with the crown, such as improper placement or discomfort, please visit your dentist as soon as possible to avert further damage.
- Consider using a mouthguard custom-made by your dentist to protect both the crown and the natural teeth from the environmental effects of grinding.

When Is It Time to Replace a PFM Crown?
Even with proper care, PFM crowns don’t last forever. Knowing the signs of wear or damage can help you address issues before they become severe.
Warning Signs of Wear or Damage
- Chips or Cracks: If the porcelain layer shows visible damage, it can compromise the crown's appearance and function.
- Increased Sensitivity: Sensitivity to hot, cold, or sweet foods may indicate decay or a loose crown.
- Dark Line Near the Gumline: This could signal gum recession, exposing the crown's metal base.
- Crown Loosening or Falling Off: If the crown no longer feels secure, it’s time to consult your dentist.
Risks of Delaying Replacement
Ignoring these signs can lead to:
- Tooth Decay: A damaged crown exposes the underlying tooth, increasing the risk of decay.
- Gum Disease: Loose crowns can create pockets for bacteria to thrive, leading to gum infections.
- Discomfort or Pain: A compromised crown may cause irritation or misalignment, affecting your bite.
Addressing these issues promptly can save you from more extensive dental treatments.
