Dental crowns are a common solution for restoring teeth that are damaged or worn down. Chosen for their durability and ability to mimic the natural look of teeth, they play a role in modern dentistry. If you’re thinking about a crown or simply want to learn more about your options, this guide breaks down the different types of crowns available, the materials they’re made from, and what to expect in terms of durability.
Which Types of Crowns Exist?
Dental crowns are typically divided into two categories based on their placement. Temporary crowns are often a temporary solution while a permanent crown is being customized in a dental lab. These consist of less durable materials, such as acrylic or composite resin, and serve as a placeholder to protect the tooth.
Permanent crowns, on the other hand, could last for years. These are carefully crafted to fit comfortably over your tooth and provide long-term protection. Permanent crowns can address a wide range of issues, such as tooth decay, fractures, or cosmetic concerns.
Another classification system divides crowns into full and partial crowns. Full crowns cover the entire surface of the tooth, restoring both its function and appearance. Partial crowns, often referred to as onlays, cover only a part of the tooth and are used in cases where the entire surface does not need to be replaced.
What Materials Are They Made From?
The material used for a dental crown determines its appearance, durability, and cost. Dentists offer several options, and the right choice depends on the tooth being treated and the patient’s needs. Here’s a breakdown of the most common crown materials:
- Porcelain Crowns: Known for their ability to blend seamlessly with natural teeth, these are a popular choice for front teeth where appearance is a priority. They offer a natural look but may not be as strong as other materials.
- Porcelain-Fused-to-Metal (PFM) Crowns: These combine the aesthetics of porcelain with the strength of metal. They are versatile and suitable for both appearance and durability, but may show a metal line near the gum line over time.
- Gold Crowns: A durable and long-lasting option. While not commonly chosen for visible teeth due to their distinct appearance, they are excellent for molars.
- Zirconia Crowns: Gaining popularity in recent years, zirconia offer exceptional strength and a natural look. They are often used as an alternative to PFM crowns and are ideal for teeth under heavy chewing pressure.
Each crown material has its benefits and limitations, so it’s necessary to discuss options with your dentist to find the best fit for your specific needs. By understanding these materials, you can make an informed decision that balances aesthetics, durability, and cost.
Are All Crowns Equally Durable?
The lifespan of a dental crown depends on several factors, including the material used and the level of care it receives. Regular dental checkups and diligent oral hygiene are pivotal for maintaining dental health and longevity. Metal-based crowns, including those made from gold or PFM, can be the most durable. They can withstand years of chewing pressure without cracking or wearing down significantly. Their metallic appearance does make them less popular for visible teeth.
Porcelain, while highly aesthetic, may be more prone to chipping if not properly maintained. Some patients opt for zirconia, as it offers a balance between strength and appearance. Temporary crowns are the least durable, as they are designed to last only until the permanent crown is placed. Factors such as grinding your teeth or consuming hard foods can affect both the choice of material and the lifespan of your crown.
Consult a Dental Specialist
Choosing the right crown for dental restorations depends on your individual needs and preferences. With so many types and materials available, it’s best to consult with a knowledgeable dental professional who can guide you through your options and recommend the best solution for your oral health. Book an appointment with a specialist to discuss which type of crown is best suited to your situation.
