Losing a crown is a frustrating experience, leaving you with a vulnerable tooth and potential discomfort. While the term "glue" might spring to mind, the reality is far more sophisticated. Dental professionals use specialized cements to secure crowns, offering a strong, long-lasting bond that protects your tooth and restores its function. This article will explore the different types of dental cements used for crown placement and address common questions surrounding this crucial aspect of restorative dentistry.
What Kind of Glue Holds a Tooth Crown In Place?
The "glue" for a tooth crown isn't a household adhesive. Instead, it's a dental cement, carefully chosen by your dentist based on factors like the type of crown, your oral health, and the specific needs of the tooth. These cements are meticulously formulated for biocompatibility, strength, and longevity. They aren't simply a binding agent; they act as a seal, preventing bacteria from entering the space between the crown and the tooth, thereby protecting against decay and infection.
Can You Use Super Glue to Fix a Tooth Crown?
Absolutely not. Super glue, or cyanoacrylate, is not suitable for fixing a dental crown. It's not designed for the oral environment; it lacks the biocompatibility needed for safe use inside the mouth, and it can't withstand the forces of chewing. Furthermore, attempting to re-cement a crown with super glue could potentially damage your tooth and lead to serious complications requiring more extensive and costly dental work. Always consult your dentist for any issues with your dental crown.
What Type of Cement is Used for Dental Crowns?
Several types of dental cement are used for crown placement, each with its unique properties:
-
Zinc Phosphate Cement: A long-standing option, known for its high strength and relatively low cost. However, it can be irritating to the pulp (the inner part of the tooth), requiring a careful technique during application.
-
Glass Ionomer Cement: Offers fluoride release, which helps to protect the tooth from decay. It's biocompatible and bonds well to tooth structure. However, it's generally less strong than zinc phosphate cement.
-
Resin-Modified Glass Ionomer Cement: Combines the advantages of both glass ionomer and resin cements. It provides fluoride release, good biocompatibility, and improved strength compared to traditional glass ionomer.
-
Resin Cement: Popular for its high strength, excellent aesthetics (it's often used for aesthetic crowns), and ability to bond effectively to various materials. Self-adhesive resin cements simplify the process, requiring fewer steps.
What Happens If a Tooth Crown Falls Off?
If a tooth crown falls off, it's crucial to act promptly. Try to locate the crown and store it in a safe place (e.g., a container of milk or saline solution). Contact your dentist immediately. They can examine the tooth, assess the underlying cause of the crown detachment, and re-cement the crown securely. Delaying treatment could lead to increased sensitivity, infection, and even further damage to the tooth.
Can I Temporarily Fix a Loose Tooth Crown Myself?
While some temporary solutions exist (like using a denture adhesive), these are not ideal and should only be considered as a very short-term measure until you can see your dentist. Improper attempts at self-repair could worsen the situation and compromise the longevity of your crown.
How Long Does Dental Cement Last?
The longevity of dental cement depends on several factors, including the type of cement used, the patient's oral hygiene practices, and the forces exerted on the crown during chewing. Generally, with proper care, a well-cemented crown can last for many years.
