When you need a crown, you immediately start thinking about the types of dental crowns and cost. This is because today there are many different types of crowns that vary depending on materials, cost, procedures, and patients’ needs.
Dental Crowns Brisbane and Clear Braces
Dental crowns are covers affixed to a broken tooth’s enamel. A crown’s purpose is to cover the portion of a tooth that is visible above the gum line. They act as a protective cap to strengthen a decayed or damaged tooth and keep it from needing to be extracted in the future. When the tooth structure is insufficient to support a filling, crowns are typically necessary. Different materials can be used to create dental crowns Brisbane, and this influences how long they will endure.

If, like me, you avoided going to the dentist as a child, perhaps because hearing the words “he needs to have a brace fitted” scared you, and you now have teeth that are not properly aligned, all is not lost. While I have no regrets about refusing to wear braces and thus avoiding the bullying that often accompanied them, I have wondered if there was anything I could do to take care of my teeth and hopefully straighten them a little. So it was with great delight that I discovered a sign in my local dentist’s office announcing the availability of clear braces.
The main types of crowns used in dentistry include:
Gold crowns are in fact a combination of copper and other metals, such as nickel or chromium. The main advantage of gold crowns is their strength and durability.
For back restorations -and depending on each patient’s needs- some dentists may suggest a gold crown as the preferred option. However, gold crowns don’t make a very popular choice today due to their color and aesthetics.
Main ADVANTAGES of gold crowns:
- They are strong and highly resistant
- They last a long time if properly cared for
- Less proportion of your natural tooth needs to be removed
- They wear down quite slowly, just like natural enamel
- They are ideal for posterior restorations (back teeth), especially second molars
Main DISADVANTAGES of gold crowns:
- Poor aesthetics: They obviously don’t look like a natural tooth
- Gold alloy crowns can affect some people and produce some side effects such as allergic reactions or swelling
All Porcelain Crowns
This is definitely the most popular type of crown used nowadays. They are entirely made of porcelain material.
Some ADVANTAGES are:
- Porcelain or ceramic crowns provide the best and most natural look. They match your surrounding teeth in shape, size, and color.
- The best option for front teeth restorations.
- They are biocompatible: that means no metal is used, so they are toxic-free.
However, the main DISADVANTAGES of porcelain crowns are:
- They are not as strong as metal crowns. Porcelain crowns can last a long time, but they have to be well taken care of.
- Patients who suffer from bruxism should opt for gold of PFM
- They may be more costly than other types of crowns, such as metal crowns.
Porcelain Fused-to-Metal Crowns (PFM)
Porcelain fused-to-metal (PFM) crowns are another widely used type of dental crowns. They provide both strength (due to their metal structure) and aesthetics (due to the porcelain coat that covers the cap).
The main ADVANTAGES of PFM crowns are:
- They provide great aesthetics and durability
- They’ve been around for over 50 years. We know they work well.
- They are less costly than all porcelain crowns
However, the DISADVANTAGES of PFMs include:
- The metal in these crowns may cause a grey line at the gumline. This may not give the 100% aesthetic look that all porcelain crowns provide.
- For people who clench their teeth, this type of crown may wear down more easily against the opposing teeth.
Zirconium is a relatively new material that combines the strength of metal with the aesthetics of porcelain crowns. High translucent zirconia and layered zirconia crowns have become a more popular choice lately.
The main ADVANTAGES of zirconia crowns are:
- They provide great aesthetics
- They are strong and long-lasting (less possibilities of chipping or breaking).
- The process can be less time consuming because zirconia can be cut and shaped at the same dental office. There’s no need to send them over to a dental lab.
- Zirconia Crowns are less likely to wear down due to their strength.
- They are biocompatible: as metal free crowns, they are not likely to cause allergic reactions.
The main DISADVANTAGES of Zirconia Crowns include:
- Their strength can make the teeth they bite against wear down easily.
- Solid Zirconia can be difficult to adjust
E- MAX: Lithium Disilicate Crowns
The newest type of crown in dentistry today is known as E -Max. It is a type of all-ceramic crown made of lithium disilicate (which is also light and thin).
The main ADVANTAGES of E-max crowns are:
- Great aesthetics. They look great in your mouth.
- They can be durable and very strong.
- They provide a great choice both for front and back teeth.
The main DISADVANTAGES of E-Max Crowns include:
- They could be more expensive, especially to the dentist (who may or may not transfer that cost to you)
- Some dental professionals have reported failures using EMax for posterior teeth, especially when doing multiple units.
