Dental crowns are a common restorative treatment used to protect and strengthen damaged teeth. But what exactly keeps these caps securely affixed to your natural tooth? The answer isn't a simple "glue," but rather a sophisticated process involving a specialized dental cement. Let's delve into the details.
What type of glue is used for dental crowns?
There's no single "glue" used for dental crowns. Instead, dentists utilize various types of dental cements, each with its own properties and advantages. The choice of cement depends on factors like the patient's specific needs, the type of crown (porcelain, metal, etc.), and the condition of the tooth. Common types include:
- Resin cements: These are popular choices due to their strong bond strength, aesthetic appeal (they can be tooth-colored), and relatively easy application. They're often used with porcelain crowns.
- Glass ionomer cements: These release fluoride, which helps protect the tooth from decay. They're often used for crowns placed on teeth with a high risk of decay.
- Zinc phosphate cements: These have been used for many years and are known for their high compressive strength. However, they are not as aesthetically pleasing as resin cements.
- Hybrid cements: These combine the properties of different cement types to offer a balance of strength, aesthetics, and fluoride release.
How is dental cement used to attach a crown?
The process of cementing a crown involves several steps:
- Tooth Preparation: The dentist prepares the tooth by removing decay and shaping it to provide a proper fit for the crown.
- Crown Try-In: Before cementation, the dentist will place the crown on the prepared tooth to ensure a perfect fit and check the bite. Any necessary adjustments are made at this stage.
- Cement Mixing: The chosen dental cement is mixed according to the manufacturer's instructions. This usually involves combining a powder and a liquid component.
- Cement Application: The dentist applies the mixed cement to the inside of the crown.
- Crown Placement: The crown is carefully placed onto the prepared tooth. Precise placement is crucial for a secure fit and proper occlusion (bite).
- Excess Cement Removal: Any excess cement that squeezes out from under the crown is carefully removed.
- Final Check: The dentist checks the bite, crown fit, and overall aesthetics.
What happens if the glue for a crown fails?
Crown cement failure is relatively rare with proper preparation and placement. However, if the cement fails, you may experience:
- Sensitivity: The tooth may become sensitive to temperature changes or pressure.
- Pain: More severe pain may indicate infection or other complications.
- Loose Crown: The crown may become loose or even fall off completely.
If you experience any of these symptoms, it's crucial to contact your dentist immediately.
How long does the glue for a dental crown last?
With proper care and maintenance, a well-cemented crown can last for many years, often a decade or more. Regular dental checkups are essential to monitor the crown's condition and ensure it remains securely attached.
Can I use home remedies to fix a loose crown?
No. Attempting to fix a loose crown at home with household adhesives or other materials is strongly discouraged. This can damage the tooth and compromise its long-term health. Always consult your dentist if you have a loose or problematic crown.
How much does it cost to reglue a dental crown?
The cost of recementing a crown will vary depending on several factors, including your location, the dentist's fees, and the type of cement used. It's best to contact your dentist for an accurate estimate.
