Different Types Of Dental Crowns: Choosing the Right Material

If you have a tooth that is damaged, your dentist might recommend covering it with a dental crown. A crown acts as a protective cap to restore a tooth’s natural shape, appearance, and function. Choosing the right material depends on factors such as the crown’s placement, your bite, your gum tissue, and your finances.

Why Would I Need a Dental Crown?

Dentists use crowns to address various oral health issues, including:

• Capping a damaged or decayed tooth.
• Strengthening a filled tooth.
• Protecting a weak tooth.
• Improving a discolored tooth.
• Holding a dental bridge in place.
• Holding together a cracked tooth.
• Protecting a tooth post-root canal.
• Capping a dental implant.

Clinical Note: A crown is often recommended following a root canal because the procedure can leave the remaining tooth structure brittle and susceptible to fracture under normal chewing forces.

The Crown Procedure: What To Expect

Typically, the two visits required for the procedure ensure a precise fit and long-lasting restoration.

First Visit

• Your dentist will discuss various crown options based on your specific needs.
• The damaged tooth is trimmed down to ensure the crown fits comfortably.
• An impression is taken by having you bite into impression paste; this is sent to a dental lab to prepare your custom crown.
• A temporary crown is inserted to protect the tooth until the permanent one returns from the lab.

Second Visit

Your dentist will remove the temporary crown and fit the permanent one, ensuring it feels correct before cementing it into place.

Different Types Of Dental Crowns

According to the ADA and the National Center for Biotechnology Information, your dentist will advise you on the best material for your situation:

• Ceramic (Porcelain): Best for front teeth as they blend with natural tooth color, though they are prone to chipping.
• Porcelain-Fused-to-Metal (PFM): Offers a balance of strength from the metal framework and a natural appearance.
• Gold Alloy: Highly durable and provides a strong bond, though it is costly and does not look natural. It may contain copper and other metals.
• Base-Metal Alloy: The strongest material, highly resistant to corrosion, and requires the least amount of tooth removal.
• IPS e.max (Lithium Disilicate): A modern, durable option for restoring natural appearance.

Clinical Note: When choosing materials, consider that metal-based crowns are often preferred for patients with bruxism (teeth grinding), as they are less likely to fracture than all-ceramic alternatives.

How to Maintain Your Crowns

With proper oral hygiene—brushing twice daily and flossing—crowns can last a lifetime. Avoid habits that put excessive pressure on your teeth, such as chewing ice or hard candies, and schedule regular checkups with your dentist.

Frequently Asked Questions

What if my crown feels loose or chips?

If your crown becomes loose, falls out, or chips, consult your dentist immediately. Red Flag: A loose crown can allow bacteria to seep underneath, potentially leading to decay of the underlying tooth structure.

Are there temporary options?

Yes, dentists may use resin crowns as temporary prosthetics while your permanent crown is being fabricated.

How do I prevent needing a crown?

The goal is to avoid damage by eating healthy foods, flossing, brushing twice daily, and attending regular dental checkups.
