Learn The Longevity of a Porcelain Dental Crown

Posted .

The dental prosthesis is a dental field aimed at restoring lost function and esthetics. In general, prostheses can be of two types: removable prostheses and fixed prostheses.

The fixed prosthesis is cemented and permanently attached to the tooth, restoring the teeth to improve dental function and the esthetics lost. Thus, fixed prostheses cannot be temporarily or regularly removed from the oral cavity with ease.

Dental crowns are a particular type of fixed dental prosthesis. These prostheses are also known as veneers. Crowns are permanently cemented to the tooth to restore the esthetics and, above all, the diminished chewing function to the compromised tooth. 

Porcelain dental crowns are usually classified according to the material:

  • Zirconia
  • Feldspathic
  • Alumina

Zirconia Crowns

Zirconia is porcelain with a high composition of zirconium oxide at 95 percent, and the remaining five percent is yttrium oxide. Zirconium is a material with a white coloration giving natural results with good brightness. 

Zirconium is very biocompatible, so the prosthesis is better tolerated by the surrounding tissues. In addition, zirconium is a resistant material.

Feldspathic Crowns

These are the first crowns made of porcelain in the dental industry. Feldspar is the primary material and also the one in charge of giving the translucency. 

This type of dental crown also has quartz in its composition, giving the crown a crystalline appearance. The last material is kaolin, which gives plasticity to the dental crown.

Alumina Crowns

Alumina porcelain crowns are similar to feldspar crowns. With aluminium oxide and a reduction in quartz, this improves the mechanical properties of porcelain.

How Long Does A Porcelain Dental Crown Last?

According to the World Health Organization, a porcelain dental crown lasts around 15 years. Having dental crowns requires general hygiene habits, i.e., brushing your teeth shortly after every meal. It is also important to floss regularly. The estimated lifespan can be significantly altered by certain factors, such as:

  • Oral dental hygiene habits
  • Skipping regular dental appointments
  • Drinking coffee 
  • Smoking
  • Using teeth with crowns or caps on dental implants to open things otherwise difficult to physically break
  • Eating hard items of food like certain types of candy that are excessively hard with dental crowns
  • Bruxism can break the porcelain crown due to the force of the muscles. You can prevent this by wearing a mouthguard.

Crowns can become loose or fall out over time. If the teeth that support them are healthy, they can be cemented again without issue.

It is crucial to maintain oral hygiene including regular checkups with your dentist to avoid these problems.
