Dental Crowns – Dental Q&A
What is a dental crown?
A dental crown is a tooth-shaped cap that fits over an existing tooth to restore its shape, size, strength, and appearance. Crowns are used to protect a tooth that is cracked, severely decayed, or has had a root canal. They are also placed on top of dental implants. Crowns can be made from porcelain, ceramic, metal alloys, or a combination of materials.
Why would I need a dental crown?
Common reasons for a dental crown include: a tooth with a large cavity too big for a filling, a cracked or fractured tooth that needs structural support, a tooth following root canal treatment, a severely worn tooth, or a tooth restored with a dental implant. Crowns are also used cosmetically to improve the shape or color of a tooth that cannot be improved with veneers.
What types of dental crowns are available?
The main types of crowns are all-porcelain or all-ceramic (most natural-looking, best for front teeth), porcelain-fused-to-metal (strong with a natural appearance), all-metal or gold alloy (most durable, often used for back molars), and zirconia (very strong and tooth-colored, popular for both front and back teeth). Your dentist will recommend the best material based on the location of the tooth, bite forces, and aesthetic goals.
How long does a dental crown last?
Dental crowns typically last 10 to 15 years, and many last 20 years or longer with good care. Longevity depends on the material, your bite forces, oral hygiene habits, and whether you grind your teeth. Patients across Gahanna and Columbus who attend regular dental checkups and practice good home care typically see the longest-lasting results from their crowns.
Do dental crowns hurt?
The procedure to place a crown is performed under local anesthesia, so you should feel little to no pain during the appointment. It is normal to experience some sensitivity and soreness for a few days after the crown is placed, particularly to temperature. If sensitivity persists beyond two weeks or you have significant pain when biting, contact your Columbus or Gahanna dentist — the bite may need adjustment or the underlying tooth may need attention.
What is the difference between a crown and a cap?
A crown and a cap are the same thing — the terms are used interchangeably. "Cap" is simply the colloquial term patients often use. Both refer to a custom-made covering that fits over a prepared tooth to restore its full shape and function. The clinical and dental industry term is "crown."
Why is my tooth sensitive after crown placement?
Mild sensitivity after a new crown is placed is very common and usually resolves within two weeks. It can be caused by the tooth preparation process, the anesthesia wearing off, or the crown needing a minor bite adjustment. If biting feels uneven or if sensitivity is severe and persistent, call your dentist — a simple bite adjustment can resolve many post-crown sensitivity issues without needing to replace the crown.
Why do dental crowns fall off?
Crowns can come loose if the dental cement washes out over time, if the underlying tooth structure is lost to decay, or if the crown is subjected to excessive force from grinding or chewing hard foods. If your crown falls off, keep it and contact your dentist promptly. Leaving the prepared tooth uncovered can cause sensitivity, decay, or shifting of nearby teeth. Your dentist can often re-cement the same crown.
What type of dental crown lasts the longest?
Metal and gold alloy crowns have the longest documented lifespan — often exceeding 20 to 30 years — because metal is highly resistant to wear and fracture. However, their metallic appearance makes them less popular for visible teeth. Zirconia crowns are the best balance of strength and aesthetics, offering excellent durability in tooth-colored material. All-ceramic crowns are the most lifelike but slightly more prone to chipping under heavy bite forces.
Can dental crowns be used for cosmetic purposes?
Yes. Crowns are used cosmetically to reshape severely misshapen teeth, to cover teeth with deep staining that whitening or veneers cannot address, and to restore teeth with large composite fillings that have darkened over time. When cosmetic improvement is the primary goal and the tooth is otherwise healthy, veneers are often a less invasive alternative worth discussing with your dentist.
How long does getting a dental crown take?
Traditional crown placement requires two appointments about two to three weeks apart. The first appointment involves preparing the tooth, taking impressions or digital scans, and placing a temporary crown. The permanent crown is delivered and cemented at the second appointment. Some offices offer same-day crowns using CAD/CAM technology, where the crown is designed and milled in the office in a single visit.
Is a dental crown worth getting?
For teeth that are cracked, severely decayed, or have had a root canal, a crown is typically the best way to save the tooth long-term. Without a crown, these teeth are at high risk of fracture or further decay that could lead to extraction. Replacing a lost tooth costs significantly more than preserving it with a crown. The Smile Method helps patients in the Gahanna and Columbus area evaluate whether a crown is the right choice before committing to treatment.
