permanent dental glue for crowns

Dental crowns are a common restorative treatment used to protect and strengthen damaged teeth. While the procedure itself is considered permanent, the term "permanent dental glue" for crowns is a bit of a misnomer. There's no single, magical adhesive that guarantees a crown will stay in place forever. Instead, the longevity of a crown relies on a combination of factors, including the skill of the dentist, the quality of the materials, and the patient's oral hygiene habits. This comprehensive guide will delve into the process, addressing common questions and misconceptions.

What is used to cement a dental crown?

Dental crowns are typically cemented using a dental adhesive, also known as luting cement. These cements come in various types, each with its own properties and strengths. Common types include:

  • Resin cements: These are popular choices because they bond strongly to both the crown and the tooth structure. They offer excellent aesthetics, as they can be translucent and closely match the color of the natural tooth. Resin cements are often used for anterior (front) crowns where aesthetics are paramount.
  • Glass ionomer cements: These release fluoride, which helps protect the tooth from decay. They're often used for posterior (back) crowns where strength is a priority.
  • Zinc phosphate cements: These are strong and reliable but can be somewhat irritating to the pulp (the soft inner part of the tooth). They're less commonly used now due to the availability of more biocompatible options.
  • Hybrid cements: Combining features of resin and glass ionomer cements, these offer both strength and fluoride release.

How long does dental crown cement last?

The longevity of the cement isn't a fixed timeframe. With proper care, a well-cemented crown can last for many years, even decades. However, factors like excessive biting force, bruxism (teeth grinding), decay around the crown margin, or trauma can all contribute to cement failure. Regular dental checkups are crucial for early detection of any issues.

Can a dental crown fall off?

Yes, although it's uncommon for a properly placed crown to fall off completely. However, it's possible for the cement to degrade or for a small portion of the crown to become loose. This might lead to sensitivity, discomfort, or a noticeable gap between the crown and the tooth. If this happens, it's crucial to contact your dentist immediately.

What causes a crown to come loose?

Several factors can contribute to a crown becoming loose:

  • Poor oral hygiene: Plaque and tartar buildup can weaken the bond between the crown and the tooth.
  • Trauma: A blow to the mouth or accidental biting on a hard object can dislodge a crown.
  • Bruxism: Grinding or clenching teeth puts excessive stress on the crown and cement.
  • Decay: Decay around the margin of the crown can compromise the bond.
  • Cement degradation: Over time, the cement can naturally degrade, particularly with certain types of cement.

How is a loose crown fixed?

If a crown becomes loose, your dentist will assess the situation. In many cases, the crown can be re-cemented. If the cement has degraded significantly, or if there is decay present, additional treatment may be necessary. In severe cases, a new crown might be required.

How can I prevent my crown from falling off?

Maintaining good oral hygiene is paramount. This includes brushing twice daily with fluoride toothpaste, flossing regularly, and using an antimicrobial mouthwash as directed by your dentist. Regular dental checkups allow your dentist to monitor the condition of your crown and address any potential problems early. Avoiding hard or sticky foods and managing bruxism (through mouthguards or other therapies) are also vital preventative measures.

In conclusion, while there's no such thing as truly "permanent" dental glue for crowns, with proper care and regular dental checkups, your crowns can provide years of reliable function and aesthetic improvement. Remember, preventative care is key to extending the lifespan of your dental restorations.
