When Do I Need a Dental Crown?
A dental crown is a protective cap placed over a damaged or weakened tooth to restore its shape, strength, and function. Crowns are essential in preserving teeth that might otherwise need to be extracted due to extensive damage. If you’re experiencing discomfort, sensitivity, or have been told you need restorative treatment, understanding when a crown is necessary can help you make an informed decision.
What Is a Dental Crown?
A dental crown is a custom-made cover that fits over a tooth, fully encasing it above the gum line. Crowns are commonly made from materials such as:
- Porcelain: Offers a natural appearance and is ideal for front teeth.
- Metal (Gold or Alloy): Extremely durable but less aesthetic.
- Zirconia: A strong and natural-looking option.
- Porcelain-fused-to-metal (PFM): Combines strength and aesthetics.
- Resin or Composite: A cost-effective option but less durable.
Crowns are commonly used for restorative and cosmetic dentistry to enhance both function and appearance.
Signs You May Need a Dental Crown
Severe Tooth Decay
When a tooth has a large cavity that a regular filling cannot support, a crown is often the best solution. Deep decay weakens the tooth structure, making it prone to breakage. A crown restores the tooth’s strength and prevents further deterioration.
Cracked or Fractured Tooth
Cracked teeth can result from trauma, grinding (bruxism), or biting hard objects. Without proper protection, a cracked tooth can worsen, potentially requiring extraction. A crown holds the damaged tooth together, preventing further breakage.
After a Root Canal Treatment
A tooth that has undergone a root canal is often weaker and more susceptible to fractures. Since the pulp inside the tooth is removed during the procedure, it becomes brittle over time. A crown helps reinforce and protect the tooth, ensuring its long-term function.
Large or Worn Fillings
If a tooth has a large filling that takes up most of its structure, it may not be strong enough to withstand daily biting and chewing forces. Over time, large fillings can cause the remaining tooth structure to crack or wear down. A crown provides additional support and prevents further damage.
Cosmetic Enhancements
Crowns can be used to improve the appearance of teeth that are severely discoloured, misshapen, or uneven. If traditional whitening or veneers aren’t suitable options, a crown can enhance the tooth’s aesthetics while also providing durability.
Supporting a Dental Bridge
A dental crown bridge is used to replace missing teeth by anchoring an artificial tooth between two crowns placed on adjacent natural teeth. This setup helps restore function and aesthetics while preventing surrounding teeth from shifting.
The Process of Getting a Dental Crown
Step 1: Consultation and Assessment
Your dentist will evaluate your tooth to determine if a crown is necessary. X-rays may be taken to assess the extent of the damage.
Step 2: Tooth Preparation and Impressions
The affected tooth is reshaped to create space for the crown. Impressions are then taken to ensure a custom fit.
Step 3: Temporary Crown Placement
A temporary crown is placed to protect the tooth while your permanent crown is being fabricated.
Step 4: Permanent Crown Placement
Once the final crown is ready, it is cemented onto the tooth, restoring its strength and appearance.
How Long Do Dental Crowns Last?
On average, dental crowns last 10 to 15 years, but with proper care, they can last even longer. Their longevity depends on:
- Good oral hygiene (brushing and flossing daily).
- Avoiding hard foods and habits like teeth grinding.
- Regular dental check-ups to monitor wear and tear.
Alternatives to Dental Crowns
If a crown isn’t the right solution, other options include:
- Fillings, inlays, or onlays: Suitable for minor tooth damage.
- Veneers: Ideal for cosmetic improvements without full coverage.
- Tooth extraction and implant: If the tooth is beyond repair.
Takeaways
Dental crowns play a crucial role in restoring and protecting damaged teeth. If you’re experiencing tooth pain, cracks, or decay, a crown may be the right solution to preserve your smile. Consult your dentist to explore your options and ensure long-term oral health.
