Temporary vs Permanent Dental Crown
When it comes to restoring damaged or decayed teeth, dental crowns are one of the most reliable and long-lasting solutions. However, many patients are surprised to learn that the crown procedure typically involves two phases—starting with a temporary dental crown and finishing with a permanent dental crown.
In this detailed guide, we’ll explore the differences between temporary and permanent crowns, including their purpose, materials, lifespan, and care instructions. We’ll also answer common patient concerns like “Can you eat with a temporary crown?”, “How long does a temporary crown last?”, and “Why is a temporary crown needed before a permanent one?”
🔹 What Is a Temporary Dental Crown?
A temporary crown is a short-term tooth cap placed over your prepared tooth while your permanent crown is being custom-made in a dental lab. It’s usually made of acrylic, composite resin, or stainless steel, and attached with temporary cement.
🔍 Purpose:
- Protects the tooth and surrounding gums.
- Prevents sensitivity and bacterial exposure.
- Helps maintain proper tooth position and bite.
- Lets the patient function comfortably for a few weeks.
🔹 What Is a Permanent Dental Crown?
A permanent crown is a custom-designed, long-term solution fabricated in a dental lab using durable materials like zirconia, porcelain, metal, or porcelain-fused-to-metal (PFM).
🛠️ Common Materials:
- Zirconia: Strong, tooth-colored, biocompatible.
- Porcelain: Highly aesthetic, great for front teeth.
- Metal: Very durable, ideal for molars.
- PFM: Combines metal strength with porcelain aesthetics.
🗓️ Lifespan:
With good care, permanent crowns can last 10–15 years or more.
🆚 Temporary vs Permanent Dental Crown: Key Differences
| Feature | Temporary Crown | Permanent Crown |
| Material | Acrylic, resin, or stainless steel | Zirconia, porcelain, metal, or PFM |
| Durability | Short-term use (2–3 weeks) | Long-lasting (10–15+ years) |
| Aesthetics | Basic look | Natural tooth-like appearance |
| Cement | Temporary adhesive | Permanent dental cement |
| Functionality | Allows chewing but may be sensitive | Full chewing, biting, and esthetics |
| Cost | Included in treatment plan | Major component of total cost |
⏳ How Long Does a Temporary Crown Last?
- A temporary crown typically lasts 2 to 3 weeks.
- It is not designed for long-term use.
- Prolonging its use may result in:
- Crown dislodgement
- Gum irritation
- Tooth shifting or misalignment
🍽️ Can You Eat with a Temporary Crown?
Yes, but with precautions:
✅ Safe Eating Tips:
- Eat soft foods (rice, eggs, pasta, cooked vegetables).
- Avoid biting on the crown side.
❌ Foods to Avoid:
- Sticky (caramel, gum)
- Hard (nuts, chips, ice)
- Chewy or crunchy (bagels, crusty bread)
❓ Why Is a Temporary Crown Placed Before the Permanent One?
Temporary crowns are essential for multiple reasons:
- To protect the exposed tooth after trimming.
- To maintain gum health and shape, aiding final crown fit.
- To allow time for lab fabrication and bite testing.
- To help you test comfort, bite, and esthetics before finalizing the permanent crown.
Skipping this step could lead to tooth sensitivity, gum irritation, or a misfit permanent crown.
🧼 How to Take Care of a Temporary Crown
- Brush gently with a soft-bristle toothbrush.
- Avoid flossing or use side-to-side motion.
- Rinse with warm salt water if sore.
- Contact your dentist if it dislodges or cracks.
🦷 When Is Anesthesia Required?
- Vital teeth (with nerves): Local anesthesia is required during tooth preparation.
- Non-vital teeth (RCT-treated): Often no anesthesia needed, unless there’s residual sensitivity.
- Adjustments or cementing: May not need anesthesia unless discomfort is expected.
🧾 Conclusion
Understanding the difference between temporary and permanent dental crowns is crucial for a smooth treatment experience. Temporary crowns act as a protective bridge between tooth preparation and permanent crown placement. They are essential for comfort, protection, and precise fitting of your final crown. Knowing what to expect, how to care for it, and when to return for your final fitting can prevent complications and ensure the longevity of your dental restoration.
❓ 10 FAQs (Not Covered in the Main Article)
- Can a temporary crown fall off?
Yes, since it’s cemented with a temporary adhesive. Contact your dentist if it dislodges. - Is it painful to get a crown?
No, the procedure is done under local anesthesia. Some mild soreness after is normal. - Can I drink hot or cold beverages with a temporary crown?
Mild temperature sensitivity is common. Avoid extreme temperatures. - What to do if the temporary crown feels high?
Call your dentist to adjust the bite to prevent jaw pain or tooth sensitivity. - Will I have a gap between the temporary and adjacent teeth?
It should be snugly fitted. Gaps may cause food trapping. - Is it normal for a temporary crown to feel rough?
Yes, the finish may not be as smooth as a permanent crown. - Can I brush normally with a temporary crown?
Yes, but use gentle strokes and avoid dislodging it. - Can a temporary crown cause bad breath?
If not cleaned properly or if loose, it may trap food and cause odor. - Can I travel with a temporary crown?
Yes, but if you’re traveling for long, ask your dentist for extra cement or schedule fitting before your trip. - How long does it take to get a permanent crown?
Usually 1–2 weeks, depending on the dental lab.
