1. Metal Or Gold Crowns
Metal crowns are a great option for out-of-site molars because they are quite strong and they rarely break. Metal and gold crowns can withstand demanding chewing. They cause less wear and tear to your teeth than other types of crowns. Another benefit of this type of crown is that less of your existing tooth needs to be removed before placement. However, metal alloys or gold crowns do not look like your natural teeth.
- 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
- 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
2. Resin-Based Dental Crowns
These crowns offer the benefit of being less expensive than other types. However, they are more likely to break than gold or porcelain crowns. Additionally, resin-based crowns tend to wear down over time from normal biting and chewing. For this reason, they typically need to be replaced more often than more durable crowns.
- All-resin dental crowns are the least expensive option.
- Crowns made out of resin usually don’t take long to install.
- Resin dental crowns can wear down faster than ceramic or porcelain crowns.
resin crowns can be a better fit for missing front teeth.
3. Ceramic Crowns
All-ceramic crowns (white crowns) are an excellent choice for front teeth. They can be fabricated in a variety of colors and tints to match your natural teeth. However, ceramic crowns are not as strong as other types. They can break more easily. Ceramic crowns have the benefit of offering a solution for patients who are allergic to metals used in dentistry.
Its strength is a definite advantage but allied to this is the attractive translucent finish of the pontic and crowns which give it a realistic appearance. This type of bridge is practically indistinguishable from your normal teeth.
Another bonus is that there is no fear of seeing a grey line at the edge of the gums. This is a particular problem with the porcelain fused to metal bridge which tended to display itself, especially at the edge of the gums.
But the all ceramic bridge removes that worry. No metal is used in the construction of the bridge plus the bridge is fitted above the edge of the gums. This ensures that your teeth and gums remain healthy and with minimal risk of an infection. Plus they are a good choice of bridge for anyone with an allergy to metal.
Whilst this is a good choice of bridge there are a few disadvantages which you need to take into account. These include:
- The ceramic can wear down the natural teeth on either side of the bridge.
- Heightened sensitivity of your teeth to different temperatures, e.g. hot drinks.
- Bacteria can become trapped around the bridge which if not removed, may lead to an infection.
- Ceramic bridges can be expensive
- They are prone to cracking or breaking
4. Fused Porcelain Crowns
This type of crown is made of porcelain but fused to metal. It is quite strong. It also has the benefit of being color-matched to your natural teeth to ensure the most natural look possible. However, it’s important to know that the strength and durability of porcelain crowns means they do cause the most wear on opposing teeth. They are also prone to chips and cracks.
- 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
- 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.
Known for their lower risk to cracking and chipping, Zirconia crowns have found high acceptability in recent times. In strength, cosmetic appeal and durability, these crowns provide better value when compared to porcelain and ceramic crowns.
- 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.
- Their strength can make the teeth they bite against wear down easily.
- Solid Zirconia can be difficult to adjust
