Dental crown. Benefits and drawbacks
What is a dental crown ?
A dental crown is a prosthetic restoration which completely caps or encircles a tooth or dental implant. Certain conditions should be met:
- the tooth will be prepared in a specific way that involves removing part of its original structure
- the tooth must be healthy or properly treated
- the original tooth crown (the part of the tooth that is visible in the mouth cavity) should be strong enough to support the restoration

The tooth is restored both functionally and aesthetically
A dental crown can restore the tooth back to its original size, shape, and color. Besides that, a crown surrounds the tooth and makes it strong again, so badly broken or decayed teeth can be strengthened with dental crowns.
A crown can cover up a stained or unusually shaped tooth or close spaces between teeth and correct minor rotations and positions of the teeth. Dental crowns can improve the general appearance, adding to patients self-confidence and giving a nicer smile.

A crown protects the tooth against further decay
A crown that fits correctly over the tooth can protect the tooth against tooth decay.
Few appointments are needed
Dental crowns require little time to be completed compared to dental bridges, removable dentures or implant supported prostheses. Depending on the type of crown, the execution may vary between 2 and 4 appointments.
Patients get used to dental crowns before long
Because of their small size, patients get accustomed to dental crowns in a short time. Generally, after a period of 1 to 4 weeks, a dental crown should feel and function like a regular tooth.
Requires tooth preparation
If performed on natural teeth, dental crowns require irreversible tooth preparation (grinding or polishing). This operation leads to the loss of large amounts of healthy tooth tissue and sometimes even endodontic procedures that lead to tooth devitalization.

Dental crowns (especially porcelain or zirconia) entail a much higher cost than a filing. The price difference between crowns and fillings has several reasons:
- constructing a dental crown is a much more laborious process than a filling
- clinical stages are more numerous
- its manufacture requires the participation of more practitioners: dentist, dental technician and sometimes other specialists.
