What are the disadvantages of porcelain crowns?
The major drawback of using all-porcelain crowns for restoring the front tooth is that the expertise required to place them is very challenging.
- Preparation might be complicated and could take a bit longer time
- Comparatively expensive
- Less durable than other types and vulnerable to breaking and cracking
Because of the breaking/cracking vulnerability, all-porcelain crowns are usually not recommended for restoring a back tooth.
How much does an all porcelain crown cost?
All-porcelain crowns for the front teeth usually cost around $1,000 - $1,500 in the United States, but some dentists might charge significantly more.
The usual price in the United Kingdom starts around £450 - £500. Canadians pay about the same as US patients, while Australians generally pay a ~10% higher price.
Prices for the back teeth might be slightly higher, but these crowns are usually recommended for the anterior region (front teeth) only.
In general porcelain crowns are more expensive than metal or porcelain fused to metal crowns (except pure gold crowns). However, their natural look and durability compensate for the higher price.
Even though dental crown prices depend on many factors, here is a list of usual porcelain crown prices in various countries:
- United State: $1,000 - $1,500

How does the procedure look like?
The procedure for the fitting a porcelain crown is similar to that of any other traditional crown:
- The tooth to be treated is cleaned, reshaped, and thus prepared for treatment.
- The tooth is also tapered a little so that the crown can snugly fit on top of the concerned tooth.
- With the help of dental putty, an impression of the tooth is taken.
- The mold is then sent to the laboratory for fabrication of the new crown.
- In the meantime, the patient gets a temporary crown fitted on the tooth.
- A period of two to three weeks is required for the crown to be prepared.
- Then the patient's tooth is fitted with the new crown. For this, the dentist roughs up the surface of the affected tooth with the help of etching acid which enables the crown to hold on to the tooth.
- After the desired fitting is obtained, the crown is firmly fixed with the help of dental cement.
Care must be taken to avoid grinding, biting into hard foodstuffs, and clenching.
