Temporary vs Permanent Crown: What Is the Difference?
If your dentist has told you that you need a dental crown, you may first receive a temporary dental crown before the final restoration is placed. This can raise a common question: What is the difference between a temporary vs permanent crown?
Both crowns cover and protect the prepared tooth, but they serve different purposes.
A temporary crown is designed to protect the tooth for a limited period while the permanent crown is being fabricated. A permanent crown is the final restoration designed for long-term function, comfort, and appearance.
Understanding the difference can help you know what to expect during crown treatment and how to care for your tooth between appointments.
What Is a Temporary Dental Crown?
A temporary dental crown is a short-term restoration placed over a prepared tooth while the permanent crown is being made.
After a tooth is prepared for a crown, the natural tooth may have reduced protection from the surrounding environment. The temporary crown acts as a protective covering during this period.
It helps:
- Protect the prepared tooth
- Reduce sensitivity
- Maintain the tooth’s position
- Support normal appearance
- Allow relatively normal chewing
- Protect the surrounding gum tissue
Temporary crowns are not intended to serve as the final restoration.
What Is a Permanent Crown?
A permanent crown is the final dental restoration that is permanently cemented or bonded to the prepared tooth.
It is custom-made based on factors such as:
- Tooth shape
- Tooth size
- Bite
- Smile appearance
- Position in the mouth
- Available tooth structure
Permanent crowns are designed to withstand normal chewing forces and provide long-term restoration of the tooth.
Temporary vs Permanent Crown: Key Differences
| Feature | Temporary Dental Crown | Permanent Crown |
| Purpose | Short-term protection | Final tooth restoration |
| Duration | Used temporarily | Designed for long-term use |
| Material | Usually provisional resin or acrylic-based material | May be ceramic, porcelain-fused-to-metal, zirconia, or metal |
| Strength | Lower | Higher |
| Fit | Provisional fit | Precisely customized |
| Appearance | Usually acceptable but less refined | Designed for natural-looking aesthetics |
| Attachment | Usually temporary cement | Permanent cement or bonding |
| Fabrication | Often made quickly | Custom fabricated using detailed impressions or digital scans |
Why Do Dentists Use a Temporary Crown?
A temporary crown is important because permanent crown fabrication may require time.
It provides protection while the final restoration is being prepared.
1. Protects the Prepared Tooth
The tooth may be sensitive after preparation.
A temporary crown helps shield it from:
- Cold
- Heat
- Food particles
- Chewing forces
- Bacterial exposure
2. Reduces Sensitivity
A prepared tooth can sometimes become sensitive.
The temporary crown provides a protective barrier over the exposed tooth structure.
3. Maintains Tooth Position
Teeth can shift slightly if a prepared tooth remains uncovered.
A temporary crown helps maintain the tooth’s position until the permanent crown is placed.
This is important because even small changes can affect the fit of the final crown.
4. Protects the Gum Area
A properly shaped temporary crown also helps the surrounding gum tissue adapt to the planned contour of the final restoration.
Why Can’t the Temporary Crown Be Used Permanently?
A temporary crown is designed for short-term use.
Although it can protect the tooth effectively, it generally does not have the same strength, precision, or long-term durability as a permanent crown.
Temporary materials may:
- Wear more quickly
- Fracture more easily
- Become loose
- Stain more readily
- Accumulate plaque if not maintained properly
Therefore, a temporary crown should be replaced with the planned permanent restoration.
What Materials Are Used for Temporary Crowns?
Temporary crowns are commonly made from provisional materials such as:
- Acrylic-based materials
- Resin-based materials
- Other provisional dental materials
The choice depends on the tooth, expected duration, and treatment requirements.
What Materials Are Used for Permanent Crowns?
Permanent crowns can be made from several materials.
Zirconia
Zirconia crowns are known for their strength and can provide a natural appearance.
All-Ceramic Crowns
These crowns can offer highly aesthetic results, particularly for visible teeth.
Porcelain-Fused-to-Metal Crowns
These combine a metal substructure with a tooth-colored outer layer.
Metal Crowns
Metal restorations are highly durable and may be suitable for selected teeth, particularly where strength is a major consideration.
Your dentist will recommend the most suitable material based on the location and condition of the tooth.
How Long Is a Temporary Crown Used?
A temporary crown is generally worn until the permanent crown is ready.
The exact duration varies depending on:
- Laboratory fabrication time
- Type of permanent crown
- Tooth location
- Gum condition
- Overall treatment plan
Your dentist will tell you when to return for the final crown placement.
How Long Can a Permanent Crown Last?
The lifespan of a permanent crown varies depending on:
- Oral hygiene
- Bite forces
- Crown material
- Tooth location
- Gum health
- Teeth grinding
- Regular dental care
A well-maintained crown can provide long-term service, but it is not considered a lifetime restoration.
Can You Eat Normally With a Temporary Crown?
You can generally eat with a temporary crown, but some precautions are important.
Avoid:
- Very sticky foods
- Hard foods
- Chewing directly on the temporary crown when possible
- Biting hard objects
These precautions reduce the risk of loosening or breaking the temporary restoration.
Temporary vs Permanent Crown: Which Looks More Natural?
Permanent crowns are generally designed with greater attention to:
- Color
- Shape
- Size
- Tooth contours
- Bite
- Relationship with neighboring teeth
Temporary crowns are primarily designed to protect the tooth and maintain function until the final restoration is ready.
Final Thoughts
Understanding the difference between a Temporary vs Permanent Crown can make the crown treatment process easier to understand. A temporary dental crown is primarily used to protect the prepared tooth, reduce sensitivity, maintain tooth position, and support function while the final restoration is being fabricated. A permanent crown is the definitive restoration, designed for long-term durability, fit, function, and appearance.

Frequently Asked Questions
What is the main difference between a temporary and permanent crown?
A temporary crown is a short-term protective restoration used while the final crown is being prepared. A permanent crown is the final customized restoration designed for long-term use.
Can I eat with a temporary dental crown?
Yes, but it is advisable to avoid sticky and very hard foods and to minimize heavy chewing on the temporary crown.
Can I brush a temporary crown?
Yes. Continue brushing gently around the temporary crown and maintain good oral hygiene.
What happens if my temporary crown falls out?
Contact your dentist as soon as possible. Keep the crown and avoid using household glue to reattach it.
Is a permanent crown stronger than a temporary crown?
Yes. Permanent crowns are fabricated from materials specifically selected for long-term function and are generally considerably stronger and more durable than provisional crowns.
Can a crowned tooth get a cavity?
Yes. The crown itself does not decay, but the natural tooth surrounding or underneath the crown can develop decay if oral hygiene is inadequate.
