For many years, tooth crowns have been a standard dental restoration. They are made to cover a tooth that has been broken or is weak, restoring its size, form, strength, and appearance. Additionally, dental crowns safeguard teeth following root canal treatment, support dental bridges, and enhance the appearance of misshapen or discoloured teeth.
But not every tooth crown is the same. There are various dental crowns, each with unique characteristics, benefits, and drawbacks. The various dental crown options and their corresponding advantages will be covered in this piece.
• Ceramic Crowns:
Ceramic crowns are a popular choice for patients looking for a natural-looking restoration. They are made of porcelain or ceramic material, resembling natural teeth’ colour and transparency. Ceramic crowns are highly durable, biocompatible, and long-lasting. They also resist wear and tear and do not cause allergic reactions.
However, ceramic crowns are not as strong as other types of crowns, and they may be prone to chipping or cracking if exposed to excessive force. They are also more expensive than different types of crowns.
• Porcelain-Fused-to-Metal (PFM) Crowns:
Porcelain-fused-to-metal crowns are made of a metal shell that is covered with a layer of porcelain. They are more durable than ceramic crowns and can withstand more force. They are also less expensive than all-ceramic crowns.
However, PFM crowns have some drawbacks. The metal shell of the crown may show through the porcelain layer, especially at the gum line, creating a greyish appearance. Also, PFM crowns may cause more wear on opposing teeth than other types of crowns.
• Gold Crowns:
Gold crowns have been used in dentistry for many years and are still popular with many patients. They are made of a gold alloy, which is highly durable and long-lasting. Gold crowns are also biocompatible and do not cause any allergic reactions. They are especially suitable for patients with strong bites, such as those who grind their teeth.
However, gold crowns are not aesthetically pleasing and may not be suitable for visible teeth. They are also more expensive than other types of crowns.
• Zirconia Crowns:
Zirconia crowns are a type of ceramic crown that is made of zirconium oxide. They are highly durable and long-lasting and can withstand more force than ceramic crowns. They are also biocompatible and do not cause any allergic reactions.
Zirconia crowns are also aesthetically pleasing and closely resemble natural teeth. They are a popular choice for patients who are looking for a restoration that is both strong and attractive.
However, zirconia crowns may require more tooth reduction than other types and are more expensive than ceramic crowns.
• E-Max Crowns:
E-Max crowns are a type of all-ceramic crown made of lithium disilicate glass. They are highly durable and long-lasting and can withstand more force than traditional ceramic crowns. They are also biocompatible and do not cause any allergic reactions.
E-Max crowns are also aesthetically pleasing and closely resemble natural teeth. They are a popular choice for patients who are looking for a restoration that is both strong and attractive. They are also suitable for patients who grind their teeth or have a history of tooth fractures.
However, E-Max crowns are more expensive than traditional ceramic crowns and may require more tooth reduction than other types of crowns.
In conclusion
When choosing a dental crown, your dentist will consider several factors, including the tooth’s location, the damage’s extent, budget, and aesthetic preferences. Your dentist may recommend a specific type of crown based on these factors, but ultimately, the decision is up to you.
