Losing a tooth crown can be a disconcerting experience, leaving you with discomfort and potentially impacting your ability to eat and speak properly. While the term "glue" might be used colloquially, it's crucial to understand that dental crowns aren't simply glued in place. Instead, they're secured using specialized dental cements, carefully selected by your dentist based on your individual needs and the type of crown. This post will explore the various types of dental cement used for securing tooth crowns and answer some frequently asked questions.
What kind of glue is used for a dental crown?
The term "glue" is a simplification. Dentists use various types of dental cement, each with unique properties tailored to different situations. These aren't household adhesives; they're biocompatible materials designed to bond securely to both the tooth and the crown material without causing harm to your gums or the underlying tooth structure. The choice of cement depends on factors like:
- The type of crown: Different materials (porcelain, metal, zirconia) may require different cements for optimal bonding.
- The condition of the tooth: The health of the remaining tooth structure influences the cement selection.
- The desired longevity of the bond: Some cements are designed for longer-lasting bonds than others.
Common types of dental cement include:
- Resin cements: These are widely used for their strong bond strength, aesthetic properties (they’re often translucent), and ease of use. They're particularly suitable for porcelain crowns.
- Glass ionomer cements: These release fluoride, which helps protect the tooth from decay. They're often used for their biocompatibility and ability to bond to dentin.
- Zinc phosphate cements: These are traditional cements known for their high compressive strength, but they can be more sensitive to moisture.
- Hybrid cements: These combine properties of different cement types, offering a balance of strength, aesthetics, and fluoride release.
How long does dental cement last?
The longevity of dental cement varies depending on several factors, including the type of cement used, the dentist's technique, the patient's oral hygiene habits, and the presence of any underlying dental issues. While a well-placed crown with proper cement can last for many years (often 10-15 years or more), it's not uncommon to require eventual replacement or repair. Regular dental checkups are essential to monitor the health of your crowns and the integrity of the cement bond.
Can dental cement fall out?
Yes, although it's uncommon for a properly placed crown to simply fall out. Several factors could lead to cement failure, such as:
- Poor cementation technique: Improper placement or insufficient curing of the cement can lead to premature failure.
- Underlying dental decay: Untreated decay can compromise the bond between the tooth and the crown.
- Trauma to the tooth: A significant impact or injury to the tooth can dislodge the crown.
- Bruxism (teeth grinding): Chronic grinding can put excessive stress on the crown and cement.
- Poor oral hygiene: Bacteria and plaque buildup can create an environment that weakens the bond.
What happens if my dental crown cement falls out?
If you notice your crown is loose or has come off entirely, contact your dentist immediately. Don't try to re-cement the crown yourself; this can lead to further complications. Your dentist will assess the situation, clean the area, and re-cement the crown or, if necessary, recommend further treatment. You might experience some sensitivity or discomfort until the crown is re-secured.
Can I use super glue on a loose crown?
Absolutely not. Household super glue or any other non-dental adhesive is not suitable for securing a dental crown. These adhesives are not biocompatible and can cause serious damage to your gums, teeth, and overall oral health. Always consult your dentist for any issues related to your dental crowns.
