How Long Should Crowns on Teeth Last?
Teeth crowns are a common dental restoration used to improve the appearance and functionality of damaged or decayed teeth. However, many patients often wonder how long these crowns are expected to last. The lifespan of a dental crown can vary depending on several factors, including the type of material used, the patient’s oral hygiene habits, and the overall oral health.
Material Used for Crowns
The longevity of a dental crown largely depends on the material used in its construction. There are several types of materials available, each with its own advantages and disadvantages:
1. Porcelain Fused to Metal (PFM): This is a popular choice for crowns, as it combines the strength of metal with the natural appearance of porcelain. PFM crowns typically last between 10 to 15 years.
2. All-Porcelain: These crowns are made entirely of porcelain and are ideal for patients who have metal allergies or want a more natural-looking restoration. All-porcelain crowns can last up to 15 years, but they may be more prone to cracking or chipping.
3. Gold: Gold crowns are known for their durability and longevity, with an average lifespan of 15 to 20 years. They are also a good choice for patients with severe decay or broken teeth.
4. Zirconia: Zirconia crowns are a newer material that offers excellent strength and aesthetics. They can last up to 15 years and are suitable for patients with high bite forces.
Oral Hygiene and Maintenance
Proper oral hygiene and maintenance play a crucial role in the longevity of dental crowns. Patients should brush their teeth at least twice a day with fluoride toothpaste and floss daily to remove food particles and plaque that can lead to decay under the crown. Regular dental check-ups and cleanings are also essential to monitor the condition of the crown and identify any potential issues early.
Overall Oral Health
The overall oral health of the patient can also impact the lifespan of a dental crown. Factors such as bruxism (teeth grinding), acid erosion, and gum disease can all contribute to the wear and tear of a crown. Patients with these conditions may need to take additional precautions, such as wearing a night guard to protect their teeth from grinding or using fluoride mouthwashes to strengthen their enamel.
Conclusion
In conclusion, the lifespan of a dental crown can vary depending on the material used, the patient’s oral hygiene habits, and overall oral health. On average, dental crowns can last between 10 to 20 years with proper care and maintenance. It is essential for patients to work closely with their dentist to ensure the longevity of their crowns and maintain optimal oral health.
