Dental crowns are an effective way to restore damaged or weakened teeth but how long can you really expect them to last? Well, most crowns typically last between 5 to 15 years but this can vary. Factors like the type of material used, where the crown is placed in your mouth and how well you care for your teeth all play a role in how long your crown will stay in good shape.
In this article, we'll break down these factors and share some simple tips for keeping your crowns in top condition. Whether you’re thinking about getting a crown or already have one, keep reading to find out how to make the most of it and keep your smile looking great!
Dental crowns are tooth-shaped caps that cover the entire tooth to provide strength, protection and improve its appearance. There are various dental crown types, including metal crowns, ceramic crowns, porcelain-fused-to-metal (PFM) crowns and zirconia crowns, each offering unique advantages and suitability based on individual needs.
Not only does a crown add strength to a tooth, it can also correct bite misalignments and protect a tooth after root canal treatment. However, some patients opt for these types of dental crowns purely for cosmetic purposes, that is to correct teeth that are stained, too small, or misshapen.
While dental crowns today are extremely strong and durable, they are not likely to last an entire tooth or lifetime. As mentioned above, on an average lifespan per natural teeth, most dental crowns last between 5-15 years before needing to be replaced or repaired. This duration appears rather vast and vague because the longevity of dental crowns depends on a few factors, including:
Based on the list above, many factors go into the longevity of dental crown procedures, which explains the 5-15 year estimation. However, studies show that when used for the right dental problems and installed properly by an experienced dentist, dental crowns can last for decades or even longer. This includes crowns that are manufactured well with the appropriate materials and cared for diligently by the dental laboratory and the patient.
A 2013 study2 that tracked the success rate of over 2,300 PFM crowns restored by the same specialist showed that 97% of those crowns lasted over a decade, and 85% of crown lasted for 25 years. This goes to show that with proper crown materials, manufacturing, professional and proper care, the chances of a permanent crown and long-term success are very high.
Over time, dental crowns may show signs of wear or damage, like looseness or tooth decay around the crowned tooth. Patients should monitor their oral health and report any discomfort to their dentist. Sometimes, it’s obvious when a crown needs replacing, such as if it falls out or is extensively damaged. Other times, symptoms may be less obvious, so it’s important not to ignore any signs to avoid pain and further dental issues. Such instances include, when:
When your new crown is first put on, your bite should feel normal. If over time your bite changes or starts to feel uneven, then it’s probably a sign that your crown is wearing off and metal crown needs to be adjusted or replaced.
If you notice receding gums around your crowned tooth, it could mean that the crown or the damaged tooth was not placed properly or that you have gum disease and need to seek treatment with your dentist.
Usually, crowns that are older than five years are more likely to run into issues due to wear and tear. It is recommended to have your crowns checked at least twice a year by your dentist to make sure everything is functioning properly.
Crowns can sometimes suffer external damage due to everyday use or pressure by bruxism. When dental crowns chip or crack, the underlying tooth may be exposed, causing pain, tenderness or swelling. Once this happens, it is imperative to fix the crown as soon as possible to protect the underlying tooth. Depending on the damage, the cracked tooth crown can be easily repaired with some quick adjustments or a replacement may be needed.
While dental crowns can effectively restore function and enhance the smile for many years, it is important to remember that they are not immune to wear and tear and may require maintenance or replacement over time to ensure optimal oral health and longevity. Apart from choosing an experienced and knowledgeable dentist, it is up to you to take care of your dental permanent crowns through proper lifestyle and oral hygiene habits, such as—
Brushing and flossing: Proper oral hygiene is crucial to prevent decay around the crowned tooth and under the crown's edge.
Diet: Avoid chewing very hard or sticky foods that can damage the crown.
Bad habits: Don't use your teeth for tasks like opening bottles or biting fingernails, which can crack or loosen the crown.
Regular dental check-ups: Attending routine dental appointments allows your dentist to check the crown's condition and address any potential issues early on.
In cases where a dental crown feels loose or falls off, it is essential to visit the dentist's office promptly for re-cementation or replacement to avoid further damage to the underlying tooth.
The lifespan of dental crowns can vary depending on various factors but with regular dental care and maintenance, dental crowns can provide durable and aesthetically pleasing solutions for restoring damaged teeth.
