What is Crowns
Materials Used in Crowns
The durability, cost, and appearance of crowns can vary a lot based on the materials used to make the crown. Common materials include porcelain, ceramic, metal alloys, gold, or a combination of these, such as porcelain fused to metal. The choice of material depends on factors like the crown’s location, the extent of the visible tooth when you smile, and your personal preferences.
Fabrication Techniques
This involves taking impressions of your teeth, which are then sent to a dental lab where the crown is meticulously fabricated. This method can accommodate all material types and typically requires two dental visits: one for taking impressions and placing a temporary crown, and another for fitting the permanent crown
Some dental practices are equipped with CAD/CAM systems that enable the dentist to design and manufacture crowns in the office during a single visit. While convenient, the choice of materials may be somewhat limited compared to lab-fabricated crowns, potentially influencing the crown's longevity.
Crowns for children's primary (baby/milk) teeth are distinct from adult crowns in their preparation, manufacturing process, and materials used. They play a very important role in maintaining space for permanent teeth and supporting the child's dental development.
Lifespan of Crowns
Maintenance
What to Expect During The Procedure
May involve antibiotics for certain medical conditions, a review of your health history, and potentially anti-anxiety medication for those with dental anxiety.
A temporary crown is placed to protect the tooth while the permanent crown is being fabricated.
Risk & Alternatives
Risks: Include potential damage to the tooth's nerve, the need for additional procedures like root canal therapy, and issues related to tooth structure reduction.
Alternatives: Depending on the situation, alternatives like fillings, onlays, or even tooth extraction and replacement may be considered.
Delaying Treatment: Delaying the placement of a crown can lead to further tooth deterioration, making preservation or restoration more challenging or even impossible.
This overview aims to equip you with the foundational knowledge needed to understand the role of crowns in dental health, the process involved in their fabrication and placement, and the considerations to keep in mind when discussing this treatment option with your dentist.
Have Questions About Crowns?
FAQs
What is a dental crown?
A dental crown is a custom-fitted covering that encases the entire visible portion of a tooth, restoring it to its original shape, size, and function. Crowns are used to repair teeth that have been damaged, decayed, or compromised in some way.
When is a dental crown needed?
Crowns are recommended for teeth that cannot be repaired with fillings or other types of restorations. Common reasons include protecting a weak tooth from breaking, restoring a broken tooth, covering a tooth with a large filling, holding a dental bridge in place, covering a dental implant, or improving the appearance of a tooth.
What materials are used for dental crowns?
Materials can include porcelain, ceramic, metal alloys, gold, or a combination, such as porcelain fused to metal. The choice depends on the tooth’s location, aesthetic considerations, and functional requirements.
How long does the process take?
Traditionally, the crown process requires two visits: the first to prepare the tooth and place a temporary crown, and the second to place the permanent crown. However, with CAD/CAM technology, some crowns can be made and placed in a single visit.
Do dental crowns look natural?
Yes, modern crowns are designed to look very natural. Porcelain and ceramic crowns can be matched to the color of your natural teeth, making them virtually indistinguishable from your real teeth.
How long do dental crowns last?
While crowns can last between 5 to 15 years or longer, their lifespan depends on wear and tear, oral hygiene practices, and personal habits. Proper care can extend their durability.
Can a crowned tooth get a cavity?
Yes, the tooth beneath a crown can still get a cavity. Therefore, maintaining good oral hygiene, including brushing, flossing, and regular dental check-ups, is essential.
Is the crown placement procedure painful?
The procedure is typically performed under local anesthesia, making it pain-free. Some sensitivity or discomfort may occur after the anesthetic wears off, but this is usually temporary.
What is the difference between a temporary and a permanent crown?
Temporary crowns are made in the dental office and used to protect the tooth while the permanent crown is being fabricated in the lab. Permanent crowns are custom-made in a dental laboratory to precisely fit your tooth.
Are there alternatives to dental crowns?
In some cases, alternatives like fillings, onlays, or dental bonding might be considered if the tooth structure is sufficient. Your dentist can advise on the best option based on your specific situation.
What care does a dental crown require?
Crowns require the same level of care as your natural teeth, including brushing twice a day, flossing daily, and regular dental check-ups to monitor the crown and underlying tooth.
