How Long Do Dental Crowns Last? [Cosmetic Dentistry FAQ]
Dental crowns are a long-term, if not a permanent, dental restoration. They are designed to last for years and years without replacement. As a patient, you want your crown to last as long as possible. So, how long is a crown meant to last and how long does it actually last? The answer depends on a number of things, like the kind of material that the crown is made of.
Types of dental crowns
One way to classify dental crowns is by the materials that go into their fabrication. The oldest and most durable types of crowns are made of noble metals, usually gold. Gold is not a reactive metal and rarely causes a bad reaction in gum tissue. However, gold crowns look nothing like natural teeth, and cosmetic dentists avoid them when they can.
Another old-school type of crown is a porcelain-and-metal crown. This type of crown is tooth-colored, except for a metallic ring at the gum line. Cosmetic dentists use this type of crown at the back of the mouth when the crown needs to act as an abutment for a bridge or partial dentures. Dental crowns with metal in them are sturdy and durable. They can last a lifetime with proper care.
Porcelain and silicon crowns are most popular with cosmetic dentists. The entire crown is tooth-colored, which makes it ideal for front teeth. This type of crown is not as durable as the metal-based alternatives. That said, it can last at least a decade.
Factors that affect dental crown longevity
There are other factors that can determine how long a crown will last.
1. The rate of wear and tear
The crowns of a person who likes to chew ice chips and open bottle caps with their teeth will not last a lifetime. How well a patient takes care of their crowns determines how long they last.
2. An individual’s oral habits
Even the sturdiest of crowns cannot survive a badly infected tooth. If the natural tooth that sits under the crown becomes damaged beyond saving, then the crown must come off. In the worst case, the tooth comes off along with the crown. This would make the person a possible candidate for an implant-supported crown.
3. The position of the crown
This relates to the issue of wear and tear. The molars bear the brunt of grinding, which means that a crown located at the back of the mouth is more likely to wear down, more so if its owner clenches their jaw often or grinds their teeth.
4. The workmanship of the cosmetic dentist
The installation of a dental crown needs a skilled dentist who will create a restoration that will fit perfectly over the tooth. The crown also needs to sit well in relation to adjacent teeth. This means that a cosmetic dentist should be precise when they:
- Prepare the patient’s tooth
- Take an impression of the patient’s teeth
- Design the restoration
The technician and machine that fabricate the tooth should also be super accurate. If any processes that go into the installation of a dental crown fail, then chances are high that the patient will need a new crown sooner rather than later.
