Losing a crown is a frustrating experience, often leading to immediate discomfort and a scramble to find a solution. While the term "glue" might be used colloquially, it's crucial to understand that dental crowns aren't affixed with common adhesives. Instead, specialized dental cements are used, each with unique properties and applications. This article will delve into the world of dental cements, explore alternatives (or rather, the lack thereof), and address common questions surrounding crown reattachment.
What Kind of Glue Holds a Tooth Crown On?
There's no "glue" in the everyday sense. Dental professionals utilize dental cement, a biocompatible material designed to bond the crown securely to the prepared tooth. Several types exist, each with its own advantages and disadvantages:
-
Zinc Phosphate Cement: A long-standing option, known for its high compressive strength. However, it can be irritating to the pulp (the soft tissue inside the tooth) and requires meticulous mixing.
-
Glass Ionomer Cement: Releases fluoride, promoting tooth remineralization and reducing the risk of secondary caries (decay around the crown). It’s less strong than zinc phosphate but more biocompatible.
-
Resin-Modified Glass Ionomer Cement: Combines the fluoride-releasing benefits of glass ionomer with the strength of resin cements, offering a good balance of properties.
-
Composite Resin Cement: Strong and aesthetically pleasing, offering excellent color matching. It's often chosen for anterior (front) teeth where aesthetics are paramount.
Can I Use Super Glue to Fix a Loose Tooth Crown?
Absolutely not. Super glue, or cyanoacrylate adhesive, is not suitable for dental applications. It's not biocompatible, meaning it can cause irritation, inflammation, and potentially allergic reactions within the mouth. Furthermore, it lacks the strength and bonding properties required to securely hold a crown in place. Using super glue could lead to serious complications, requiring more extensive and costly dental intervention.
How Long Does Dental Cement Last?
The longevity of dental cement depends on several factors, including the type of cement used, the quality of the crown preparation, the patient's oral hygiene, and the forces exerted on the crown during chewing. Generally, well-placed crowns cemented with appropriate materials can last for many years, even decades. However, regular dental checkups are essential to detect any potential issues early on.
What Happens if My Tooth Crown Falls Off?
If your crown falls off, contact your dentist immediately. Do not attempt to re-cement it yourself. Your dentist will examine the tooth and crown to assess the situation, clean the area, and re-cement the crown using the appropriate technique and material. In some cases, the tooth may require further treatment before the crown can be reattached.
Can I Re-cement a Tooth Crown Myself?
While some over-the-counter dental cements exist, attempting to re-cement a crown at home is strongly discouraged. The procedure requires precision and a sterile environment to avoid infection and ensure proper bonding. Improper re-cementing can lead to further damage to the tooth or surrounding tissues, resulting in more complex and costly dental procedures later.
How Much Does it Cost to Re-cement a Tooth Crown?
The cost of re-cementing a tooth crown varies depending on several factors, including your location, the dentist's fees, and the complexity of the procedure. It's generally less expensive than getting a new crown, but it's best to contact your dentist directly for an accurate estimate.
In conclusion, while the term "glue for a tooth crown" might seem straightforward, the reality is more nuanced. Using the correct dental cement is crucial for a secure, long-lasting, and safe restoration. Always consult a dentist for any issues related to your dental crown; never attempt a DIY fix.
