A Complete Guide by SmileOnPerth
Dental crowns are custom‑made restorations designed to protect and strengthen teeth that are damaged, weakened, or structurally compromised. They help restore the tooth’s shape, size and function, and can also support the overall appearance of your smile. If you’re considering a dental crown, one of the most common questions is: how long do dental crowns actually last?
While crowns are intended to be a long‑term solution, they are not permanent. Over time, normal wear, oral habits, and general dental health can influence how long they remain in good condition. The good news is that crowns can be replaced if needed, and with the right care, they can last many years.
This guide explains how long different types of crowns typically last, how to care for them, and answers common questions patients often ask at SmileOnPerth.
How Long Should a Dental Crown Last?
Most dental crowns (gold crown, silver crown, platimum crown) last between 5 and 20 years, depending on:
-
The material used
-
Your oral hygiene habits
-
Your bite and chewing patterns
-
Lifestyle factors such as teeth grinding
-
Regular dental check‑ups and maintenance
Gold and platinum crowns are known for exceptional durability and often last the longest. Porcelain crowns, commonly used for front teeth due to their natural appearance, typically last 10–20 years with proper care. Ceramic and resin crowns can also last many years when maintained well.
How to Help Your Dental Crown Last Longer
The longevity of your crown depends not only on the material but also on how well you care for it. Here are key steps to protect your crown and support long‑term success.
1. Dental Crown Aftercare (First 2–3 Weeks)
After your crown is placed, the dental cement needs time to fully set. During this period:
-
Avoid biting down on hard foods
-
Limit chewy or sticky foods such as caramel or lollies
-
Chew on the opposite side where possible
-
Be gentle when brushing and flossing around the new crown
This early care helps ensure the crown bonds securely to the tooth.
2. Maintain Excellent Oral Hygiene
Good oral hygiene helps prevent decay around the crown and supports gum health.
-
Brush twice daily with a soft‑bristled toothbrush
-
Floss regularly
-
Limit sugary snacks and drinks
-
Use fluoride toothpaste to strengthen surrounding tooth structure
Healthy gums and teeth help your crown stay stable and functional for longer.
3. Be Mindful of What You Chew
Even after the crown has fully set, certain foods and habits can shorten its lifespan.
Avoid or limit:
-
Hard nuts
-
Ice cubes
-
Chewy lollies
-
Sticky sweets
-
Chewing pens or fingernails
These can cause cracks, dislodgement, or unnecessary wear.
4. Visit Your Dentist Regularly
Routine dental visits allow your dentist to:
-
Monitor the condition of your crown
-
Check for early signs of wear
-
Assess the health of the tooth underneath
-
Provide professional cleaning to reduce plaque build‑up
If a crown becomes loose, chipped, or damaged, early attention helps prevent further complications.

Frequently Asked Questions About Dental Crowns
What Are Dental Crowns Made Of?
Crowns can be made from:
-
Porcelain
-
Ceramic
-
Resin
-
Metal alloys such as gold or platinum
-
Porcelain‑fused‑to‑metal (PFM)
Porcelain, ceramic and resin crowns blend naturally with surrounding teeth, while metal crowns are often chosen for back teeth due to their strength.
How Is a Crown Placed on a Tooth?
A crown is secured using permanent dental cement. Once placed, it may take a couple of weeks for the cement to fully set, which is why gentle chewing is recommended during the early phase.

A typical crown procedure involves two appointments:
First visit:
-
- The tooth is assessed and prepared

-
The tooth is shaped to fit the crown
-
An impression is taken
-
A temporary crown is placed

Understanding Treatment Risks
Dental procedures, including porcelain veneers, carry inherent clinical risks. These include, but are not limited to, tooth sensitivity, irreversibility of tooth preparation, risk of fracture, potential for pulp involvement, and the requirement for future replacement. Individual outcomes cannot be predicted with certainty. We present this information clearly so that patients are fully informed before seeking a consultation.
