Crowns protect weak teeth from further damage while re-establishing the ability to chew. Though crowns may last a long time, they do not have an indefinite lifespan, and multiple clinical factors and lifestyle choices determine their longevity. This blog provides factual information, supported by reputable dental guidelines, on how long crowns remain functional and what maintains their longevity.
Average Lifespan of Dental Crowns
The average dental crown lasts between 10 and 15 years, according to the ADA; however, with continued good oral hygiene and routine dental visits, crowns can remain functional for 15 to 25 years. The primary purpose of a dental crown is to reinforce the tooth’s structure so that the tooth can withstand the forces of biting.
Many factors affect the lifespan of a dental crown. The material used for the crown will undoubtedly affect its longevity. Still, ultimately, the longevity of dental crowns in Rocklin, CA is more closely related to an individual’s oral hygiene, habitual preventive measures to avoid decay, and the degree of professional care received.
Crown Materials and Durability
Different dental crown materials respond differently to the forces of chewing and eating daily.
- Porcelain and ceramic (ceramic) crowns provide a natural appearance; however, the average longevity of these crowns is 10 to 15 years.
- Zirconia crowns offer greater strength than porcelain or ceramic crowns, making them appropriate for families with heavier bite forces or molar teeth. They have an average lifespan of 15 to 25 years.
- Porcelain-fused-to-metal (PFM) crowns are also strong and have an average lifespan of 10 to 20 years.
- Gold and metal alloy crowns have the highest durability of any material besides composite resin crowns; due to their hardness and resistance to wear, they may last longer than 20 years if properly cared for.
Factors That Affect Crown Longevity
The longevity of dental crowns in Rocklin, CA, depends on how well they protect the tooth beneath them. A crown never decays because it is made of metal or porcelain, but the tooth structure underneath can decay if plaque builds up on it.
Considerable positives:
- Daily brushing & flossing.
- Regular checkups & examinations.
- Alignment of the upper and lower jaw.
- Avoidance of hard food items (such as ice, nut shells, and hard candy).
- Use of a night guard for bruxism (if applicable).
Considerable negatives:
- Poor oral hygiene.
- Gum recession has exposed some of the crown margins.
- Grinding or clenching without the use of a guard.
- Increased cavities due to a high-sugar diet.
- Failure to return for routine office visits.
If decay occurs beneath the crown, it must be replaced regardless of age.
Signs a Crown Needs Evaluation or Replacement
Crowns need to be evaluated regularly during dentist visits. Replacement is recommended when structural integrity or function is compromised.
Signs your crown may be failing include:
- Mobility or looseness.
- Fractures, chips, or wear lines
- Pain or pressure while chewing
- Recurrent decay or dark staining at the margins
- Food debris trapped at the gum lines
- A visible gap due to gum recession
If an evaluation is performed early, the risk of complications (e.g., root canal infection, tooth loss) is lower.
How to Extend the Functional Life of a Crown
Good maintenance of a crown will significantly increase the functional life of the restoration. Some suggested ways to maintain a crown include:
- Brush teeth using fluoride toothpaste at least 2 times a day
- Floss around the margins of your crowns to help prevent decay
- Use an alcohol-free mouthwash to help reduce plaque buildup
- Avoid eating sticky or crunchy foods that place undue stress on crown materials
- Have a dental check-up every 6 months to keep an eye on your crown
- Wear a custom nightguard (if you grind your teeth) to protect your crowns from wear
- Take care of gum disease as soon as it is diagnosed, so that the supporting tissues (bone & gums) can be saved
Crowns maintained in the methods listed above often exceed the average lifespan of a crown.
Realistic Expectations for Patients
While crowns are strong and dependable replacements for lost teeth, they should be viewed as a long-term solution that may need to be replaced later. With proper care and maintenance:
- Many crowns will last longer than 15 years
- Crowns made of the strongest materials (zirconia, gold, etc.) will last the longest
- Regular monitoring will prevent unexpected crown failure
- Good home care minimizes the risk of complications associated with crowns
- A crown that functions effectively for 20+ years is considered an excellent success
Conclusion – Long Lifespan Depends on Maintenance, Not Just Material
Dental crowns in Rocklin, CA, are one of the most stable restorations when properly maintained. By following an effective hygiene method, wearing a dental night guard, and regularly attending checkups, a patient can generally expect their dental crowns to last longer than expected. Ultimately, as dental conditions change over time, it will be necessary to replace crowns; however, the intent is to maximize their lifespan for as long as possible.
To maintain crown health, to receive a dental evaluation, or to place new crowns, you should schedule an appointment with Rocklin Comprehensive Dentistry for an accurate assessment of your situation.
FAQs
What is the average lifespan of a dental crown?
Crowns typically last 10–15 years; with proper oral care, most will last even longer.
Can you have a dental crown for 25 years?
Yes. Because of the properties of Zirconia and Gold, most of them will last for more than 20 years even under very low-stress conditions.
Does your oral hygiene affect the lifespan of a dental crown?
Yes. If you do not maintain good oral hygiene, the areas around your crowns will decay more easily, significantly reducing their lifespan.
Which material will provide the greatest longevity of a dental crown?
Zirconia and Gold crowns are generally the best choice if you are looking for the ideal functional longevity.
Would a dental crown feel different when chewing?
It is normal for a dental crown to feel slightly different for the first little while you are chewing with it. It is advisable to call your dentist for a proper evaluation if any discomfort persists beyond that initial period of acclimatization.
Can you repair a damaged dental crown instead of replacing it?
Many crowns with minor chips can often be repaired. A crown with extensive structural failure will require replacement.
If you have a loose dental crown and choose to ignore it, what will happen?
If you ignore your loose crown, you may experience decay, infection, or tooth fracture. A visit to your dentist for an evaluation is recommended.
