Dental crowns are a reliable solution for restoring damaged or weakened teeth. They help strengthen teeth, improve their shape, and restore function.
If you are considering a dental crown in St Marys, NSW, it is important to understand the different types available. Western Sydney Smiles provides a variety of crown options to suit different dental needs.
What Are Dental Crowns?
A dental crown is a custom-made cap placed over a tooth to restore its strength, function, and appearance. Crowns are often recommended for teeth with large fillings, fractures, or after root canal treatment. They are also used for cosmetic purposes to improve the appearance of a tooth.
Dental crowns protect and reinforce a weakened tooth structure, preventing further damage. When combined with dental bridges or implants, they also serve as a long-term solution for missing or broken teeth. Understanding the different materials available can help you choose the best option for your specific needs.
Types of Dental Crowns
There are several types of dental crowns, each with distinct benefits. The choice depends on factors such as durability, aesthetics, and individual dental requirements.
1. Porcelain Crowns
Porcelain crowns are made entirely from ceramic materials, making them a popular option for restoring front teeth. They offer a natural look and blend well with surrounding teeth.
Pros of Porcelain Crowns
- Tooth-coloured for a natural appearance
- No metal content, reducing allergic reactions
- Biocompatible and safe for gum tissue
Cons of Porcelain Crowns
- Less durable than metal-based crowns
- More prone to chipping under heavy pressure
Porcelain crowns are an excellent choice for those who prioritise aesthetics, especially for visible front teeth. They mimic the translucency of natural enamel, making them one of the most realistic options available.
2. Porcelain-Fused-to-Metal (PFM) Crowns
PFM crowns combine the strength of metal with the aesthetics of porcelain. They have a metal base covered with a porcelain layer, balancing durability and appearance.
Pros of PFM Crowns
- Stronger than all-porcelain crowns
- Aesthetic appearance with added durability
- Suitable for both front and back teeth
Cons of PFM Crowns
- Metal base may become visible near the gum line over time
- More wear on opposing teeth compared to other materials
PFM crowns are widely used due to their durability and ability to provide a natural look while maintaining high strength. They are often recommended for teeth that experience moderate chewing pressure.
3. Zirconia Crowns
Zirconia crowns are known for their strength and durability. They resist wear and fractures, making them ideal for molars and patients who grind their teeth.
Pros of Zirconia Crowns
- Extremely strong and resistant to damage
- Can be colour-matched to natural teeth
- Less risk of wear on opposing teeth compared to PFM crowns
- Highly biocompatible, reducing the risk of allergic reactions
Cons of Zirconia Crowns
- Can appear slightly more opaque than natural teeth
- Requires advanced dental equipment for adjustments
Zirconia crowns are often recommended for patients needing long-lasting solutions, especially for molars where strength is a priority.
4. Metal Crowns
Metal crowns are made from alloys containing gold, platinum, or base metals like nickel and chromium. They are highly durable and rarely break or chip.
Pros of Metal Crowns
- Long-lasting and resistant to fractures
- Requires minimal tooth structure removal
- Ideal for back molars where strength is essential
Cons of Metal Crowns
- Metallic colour is noticeable
- Less preferred for visible front teeth
Metal crowns are one of the most durable options. They are commonly used by patients who prioritise function over aesthetics, particularly for molars.
5. Resin Crowns
Resin crowns are an affordable option but are less durable than other materials. They are typically used as a temporary solution rather than a long-term restoration.
Pros of Resin Crowns
- More affordable compared to other crowns
- Can be placed quickly as a temporary option
- Less invasive preparation required
Cons of Resin Crowns
- Prone to wear and fractures
- Less durable than metal or ceramic crowns
- Requires frequent replacement
Resin crowns are commonly used for temporary restorations before a permanent crown is placed.
Comparing the Different Types of Dental Crowns
| Type of Crown | Strength | Aesthetic Appeal | Best Used For |
| Porcelain | Moderate | High | Front teeth |
| PFM | High | Moderate | Front and back teeth |
| Zirconia | Very High | Moderate to High | Molars and high-pressure areas |
| Metal | Very High | Low | Molars, high bite force areas |
