Dental crowns are one of modern dentistry’s most common and effective restorative treatments. Whether dealing with a damaged tooth or looking to enhance your smile, crowns can offer both functional and aesthetic benefits. At Innovative Dental, we’ve compiled answers to the most frequently asked questions about dental crowns to help you feel informed and confident. 

1. What is a dental crown? 

A dental crown is a tooth-shaped cap placed over a damaged, decayed, or misshapen tooth. It restores the tooth’s original shape, size, strength, and appearance while providing protection and improving function. 

2. Why might I need a dental crown? 

Crowns are used for a variety of reasons, including: 

• Severely decayed teeth 
• Cracked or fractured teeth 
• After root canal treatment 
• Worn-down or eroded teeth 
• Large fillings needing support 
• Aesthetic improvements (e.g., discolouration or misshapen teeth) 
• Supporting a dental bridge or covering a dental implant 

3. What materials are dental crowns made from? 

Crowns can be made from: 

• Porcelain or ceramic: Natural-looking, ideal for front teeth 
• Metal alloys: Very durable, commonly used for molars 
• Porcelain fused to metal (PFM): Combines strength and aesthetics 
• Resin: More affordable, used chiefly for temporary crowns 

4. How are dental crowns placed? 

The crown procedure typically involves these steps: 

1. Preparation: The dentist numbs the tooth and removes part of the enamel to shape the tooth. 
2. Impression: A mould or digital scan is taken for a custom fit. 
3. Temporary Crown: A temporary crown is placed while the permanent one is crafted. 
4. Placement: At a follow-up visit, the permanent crown is cemented. 

5. How long do dental crowns last? 

With proper care, crowns can last 10 to 15 years, or even longer. Their lifespan depends on: 

• Oral hygiene habits 
• Avoiding teeth grinding or biting complex objects 
• Quality of the crown material 

6. Are dental crowns painful to place? 

Not at all! The procedure is performed under local anaesthesia, so you won’t feel pain. Some sensitivity may follow the appointment, but usually fades within a few days. 

7. How do I care for a dental crown? 

To prolong the life of your crown: 

• Brush and floss daily 
• Visit your dentist regularly 
• Avoid chewing on ice or complex objects 
• Wear a nightguard if you grind your teeth 

8. Can a dental crown be repaired if it gets damaged? 

Small chips may be repaired with dental bonding. However, severely damaged crowns usually need to be replaced. 

9. Are dental crowns covered by insurance? 

Many dental insurance plans cover crowns if they are medically necessary. However, coverage varies—check with your provider for specific benefits and limits. 

10. What are the risks or disadvantages of dental crowns? 

Although dental crowns are safe and effective, possible risks include: 

• Post-treatment sensitivity 
• Crown loosening or falling off 
• Allergic reactions (rare) 
• Wear on opposing teeth 
• Need for replacement over time 

11. How much do dental crowns cost? 

The cost depends on the material used and the complexity of your case. On average, crowns cost between $1,500 and $2,500 per tooth, with porcelain crowns at the higher end. Insurance may help offset some of the cost. 

12. Can a dental crown be whitened or changed? 

No, dental crowns cannot be whitened like natural teeth. If you want a whiter shade, the crown must be replaced. 

13. Is the procedure suitable for children? 

Yes—sometimes, especially if a baby tooth is severely decayed or broken. Your dentist will evaluate if a crown is appropriate based on the child’s age and tooth development. 

14. What are temporary crowns, and how long do they last? 

Temporary crowns are placed to protect the tooth while your permanent crown is being made. These are less durable and typically last a few weeks. Be gentle while eating and cleaning during this time. 

15. How do I know if I need a crown or another type of restoration? 

Your dentist will assess your tooth’s condition and may recommend: 

• Fillings (for minor decay) 
• Inlays/onlays (for moderate damage) 
• Crowns (for extensive damage or after root canal treatment)
