How Much Tooth Structure Is Needed For A Crown?

Team Dental Crowns, Uncategorized

A dental crown is a custom-made appliance that restores a compromised natural tooth. Dental crowns cover and protect broken, decayed, or severely discolored teeth. A crown can restore a tooth's chewing ability and attractive appearance.

Many patients need to know whether their damaged teeth have enough structure left to hold a dental crown. In general, a tooth needs about two millimeters (or one-fourth) of its natural surface to attach a dental crown.

This blog explains how dental crowns work, shares their benefits, and gives a step-by-step breakdown of the crown process.

About Dental Crowns

A dental crown preserves and protects the structure of a natural tooth. It works like a custom-fitted cap that covers the damaged tooth and restores its natural shape.

Crowns can restore teeth in these situations, among others:

  • Chipped or cracked tooth due to dental trauma
  • Severe decay that a filling cannot repair
  • After a root canal

Benefits of Dental Crowns

Restores Chewing Ability

With a dental crown, you will not need to chew around a problem tooth. A properly placed dental crown should match natural chewing ability.

Creates an Attractive Result

A tooth-colored dental crown can improve your smile, giving your tooth a healthy and brilliant appearance.

Durable and Long-Lasting

Dental crowns tend to last about 5 to 15 years and may last decades with proper care.

Choice of Materials

Patients can choose from multiple material options, including same-day ceramic crowns, porcelain, metal, and gold.

The Dental Crown Process

Getting a crown is an easy, non-invasive procedure. The first step is taking digital impressions of the existing tooth and its neighbors to create a perfect fit.

Next, the dentist numbs the area using a local anesthetic to prevent any discomfort. The dentist then prepares the tooth by removing any broken or decayed areas. Another set of digital impressions follows.

If you have opted for a same-day ceramic crown, the dentist will design and fabricate it using a sophisticated CAD/CAM system located in their office. Your dentist can place a CAD/CAM crown in the same appointment.

The dentist will send specifications for other crown types to a laboratory for manufacture. When your crown comes back from the lab, usually in one to two weeks, you will receive a call to schedule another appointment.

Placing a crown is a trouble-free process. The dentist adjusts the crown to ensure a perfect fit and fine-tune your bite. Finally, they cement the crown in place.

Frequently Asked Questions About Dental Crowns

What happens if I do not have enough tooth surface for a crown?

You may be able to undergo crown lengthening, a simple procedure that removes a small amount of gum tissue to expose more tooth surfaces.

Does every root canal require a crown?

In some cases, a dentist will restore a root canal-treated tooth with a filling, but crowns last longer and better protect the natural tooth.
