Temporary vs Permanent Crowns: What’s the Real Difference and Why It Matters
When a dental crown is recommended, patients are often informed that the treatment involves both a temporary crown and a permanent crown. While these terms are commonly used, the difference between them is not always clearly understood.
Temporary and permanent crowns serve distinct purposes at different stages of treatment, and understanding how they differ is essential for protecting the tooth, avoiding complications, and ensuring long-term success.
This article explains the key differences in a clear, practical manner, so patients know what to expect and how to care for their tooth throughout the crown process.
First, Why Are Crowns Done in Two Steps?
A dental crown isn’t just placed on a tooth like a cap. The tooth must be reshaped, scanned or impressed, and then a custom crown is made specifically for your bite and jaw alignment.
That process takes time. During that gap, your tooth is exposed and vulnerable. This is where temporary crowns come in.
What Is a Temporary Crown (and What It Is NOT)?
A temporary crown is a short-term protective cover placed immediately after your tooth is prepared for a crown.
It is not meant to be strong, long-lasting, or perfect-looking.
What a Temporary Crown Actually Does
- Protects the prepared tooth from sensitivity
- Prevents the tooth from shifting
- Protects the gum around the tooth
- Allows basic chewing and speaking
- Holds space for the permanent crown
What a Temporary Crown Does NOT Do
- It does not last long
- It does not handle heavy chewing
- It does not seal the tooth permanently
- It does not look exactly like a real tooth
Materials Used
Temporary crowns are made from:
- Acrylic
- Composite resin
- Stainless steel (mostly for children)
These materials are easy to remove but weaker by design.
How Long Can You Wear a Temporary Crown?
Typically 1–3 weeks. Wearing it longer increases the risk of:
- Crown breaking or falling off
- Tooth decay underneath
- Gum inflammation
- Bite problems
What Is a Permanent Crown?
A permanent crown is the final, long-term restoration designed to replace the temporary crown.
It is custom-made to:
- Match your natural tooth colour
- Fit your bite precisely
- Handle daily chewing forces
- Protect the tooth for many years
Common Permanent Crown Materials
Dentists select materials based on strength and appearance needs:
- Zirconia crowns – very strong, long-lasting
- Ceramic or porcelain crowns – highly aesthetic
- Porcelain-fused-to-metal crowns
- Metal or gold crowns – strongest, less cosmetic
How Long Do Permanent Crowns Last?
Permanent dental crowns typically last 10–15 years, and with good oral care, many can last 20 years or longer. Their lifespan depends on factors such as the crown material, oral hygiene, bite pressure, and daily habits.
While crowns themselves do not decay, the tooth underneath can be affected if proper care is not maintained. Regular brushing, flossing, avoiding excessive force, and routine dental check-ups help extend the life of a permanent crown and maintain long-term oral health.
Temporary vs Permanent Crowns: The Differences That Actually Matter
| Factor | Temporary Crown | Permanent Crown |
| Purpose | Short-term protection | Long-term solution |
| Strength | Low | High |
| Appearance | Basic | Natural |
| Material | Acrylic/resin | Zirconia, ceramic, metal |
| Cement | Temporary | Permanent |
| Lifespan | Days to weeks | Years |
What Really Happens During Crown Treatment?
Tooth Preparation and Temporary Crown Placement
- The dentist examines the tooth and carefully reshapes it to allow proper crown fit and long-term stability.
- A digital scan or dental impression is taken to design a custom permanent crown.
- A temporary crown is placed to protect the prepared tooth, reduce sensitivity, and maintain proper tooth alignment.
Waiting Period
- The permanent crown is custom-made in a dental laboratory based on the scans or impressions.
- During this time, the temporary crown continues to protect the tooth and support normal chewing and speaking.
Permanent Crown Fitting and Cementation
- The temporary crown is gently removed from the tooth.
- The permanent crown is placed and checked for accurate fit, comfort, and appearance.
- The dentist adjusts the bite as needed to ensure proper alignment and chewing function.
- Once confirmed, the crown is permanently cemented in place for long-term use.
- Some clinics offer same-day crowns, which eliminate the temporary crown stage; however, not all patients are suitable candidates.
How to Protect Your Temporary Crown
Temporary crowns fail mostly due to normal eating habits.
Do this:
- Avoid sticky foods (gum, caramel, toffee)
- Avoid hard foods (nuts, ice, hard candy)
- Chew on the opposite side
- Brush gently
- Floss by sliding sideways, not pulling up
If your temporary crown falls off, do not ignore it. Call your dentist immediately. An exposed tooth can become painful or damaged very quickly.
Caring for a Permanent Crown
Once the permanent crown is placed:
- Brush twice daily
- Floss around the crown
- Avoid biting ice or very hard objects
- Get regular dental checkups
A crown protects the tooth, but decay can still occur at the edges if hygiene is poor.
Which One Is Better: Temporary or Permanent Crown?
This isn’t a choice between two options. They serve completely different purposes.
- Temporary crowns protect your tooth during treatment
- Permanent crowns restore your tooth for the long term
Skipping or delaying the permanent crown can lead to:
- Tooth fracture
- Infection
- Crown failure
- Higher treatment costs later
Bottom Line
Temporary crowns are meant to protect your tooth for a short time, while permanent crowns are the actual long-term solution.
Following the complete crown treatment and caring for each stage properly helps reduce pain, improve comfort, and ensure long-lasting results with fewer dental problems.
