Dental crowns are one of the most sought-after treatments and are used commonly by dentists almost every day. They provide protection to a damaged or weak tooth, helping the dentist preserve that tooth for as long as possible. However, as with all forms of dental treatments, dental crowns are not everlasting. Most crowns need to be changed after some time. But how long is a while? How long does a dental crown usually last? The answer may come as a shock to some people.
When are Crowns Needed?
It may be helpful to start here, with the question of, “Why do we need crowns in the first place?”
Dental crowns are needed when the tooth requires further protection from harm. Such cases include:
1. After Root Canal Treatments
When the tooth nerve and main source of nutrition are removed, a tooth will need protection from the forces of chewing.
2. Trauma & Fracture
When the tooth suffers a blow that breaks some or most of it, in most cases a crown is needed. This is not only to replace the missing part but also to protect what remains against further harm.
3. Large Cavities
Cavities are usually treated with fillings. However, if the cavity is large, a simple filling may not withstand the forces of chewing. Therefore, a crown is needed to protect and counteract these forces.
How Long Does a Dental Crown Usually Last?
Dental crowns are one of the treatments that have more longevity compared to others. Fillings, for example, last about 5 years before needing to be changed. Crowns – on average – last anywhere between 8 and 12 years!
This may be shocking, considering you may have a friend or relative who has had their crown intact for over 20 years. That is true in some cases. For that reason, you need to know that there are many factors that affect the longevity of your crowns. These factors include:
1. The Material of the Crown
Older metal and porcelain crowns are rarely used nowadays since they offer very little longevity compared to zirconium and all-porcelain crowns.
2. The Margins of the Crown
If the crown is well made so that it fits the underlying tooth perfectly, there is no pathway for the bacteria to enter and sabotage that bond.
3. Your Oral Hygiene
Oral hygiene affects everything inside your mouth. That is doubly true for artificial structures such as crowns which need extra vigilance while cleaning.
4. Follow-up Frequency
If you always keep your follow-up appointments for dentists to check your crowns with X-rays and careful examination, it is more likely they will last longer.
What Can I Do to Make My Crowns Last Longer?
The longevity of the crowns depends mainly on 2 factors: the skill and dedication of your dentist, and how well you keep your mouth clean. While you can’t do anything about the first item, you can certainly keep your mouth as clean as possible. Set up a strict oral hygiene regimen of brushing and flossing, as well as following up frequently with your dentist so that they can fix any problems that arise quickly.
There is no single answer to the question of how long does a dental crown usually last. It depends on many factors, as we’ve explained. However, we can help keep track of your crowns if you keep up with your follow-up appointments.
