A dental crown is a tooth-shaped “cap” or cover that we place over a tooth that is badly damaged from trauma or decay to restore its shape, strength, size and functionality. We also use them for cosmetic reasons to improve a tooth's appearance with natural, life-like results. Crowns are generally handcrafted by dental laboratory technicians using high-quality dental porcelains (ceramic materials) that are made to fit on precise replicas (molds) of the prepared teeth. In our office, we generally make temporary crowns to protect the teeth to keep them comfortable and functional while the permanent crown(s) is being made. And once a crown is placed (cemented into position), it fully encases the entire visible portion of the tooth that lies at and above the gum line.
When Are They Necessary?
There are many reasons a crown may be needed. Some of these include:
- To repair a tooth that is worn down, broken or badly damaged by decay or injury.
- To restore a tooth so severely damaged by decay that the tooth's structure is no longer intact enough to place a filling or where a filling can't restore the tooth to its former strength.
- To protect a tooth that has minor cracks or fractures from further damage.
- To create a bridge to replace a missing tooth, in which the teeth on either side, known as abutments, must be “crowned” to attach to the “pontic” (from the French word, “pont” that means bridge).
- To create the visible part of the tooth that sits atop a dental implant.
- To improve the appearance of a tooth providing a more appealing shape and color.
If you've ever watched Dancing with the Stars on television, you've no doubt noticed the vivacious and talented Cheryl Burke, whose ballroom dance moves are as captivating as her bright smile. In fact, Cheryl considers her smile to be one of her most important assets as a professional dancer.
“As a performer, you're basically smiling the whole time,” Cheryl told Dear Doctor magazine recently in an exclusive interview. “It's just really important to take care of your teeth and have a great smile.”
Cheryl is very conscientious about caring for her smile, but that wasn't always the case. In the Dear Doctor interview, Cheryl revealed that her teeth suffered from ineffective oral hygiene when she was younger. “I definitely had my share of cavities,” Cheryl recalled, adding that she believed this was her own fault. “I didn't use floss,” She explained. “I think when you do floss frequently, it helps to reduce the chances of getting cavities. It took me a while to figure it out.”
Once Cheryl did figure it out, she was able to make cavities a thing of the past. But in order to make sure the effects of her prior tooth decay did not mar her lovely smile, she made sure her dentist — who is also her stepdad! — gave her tooth-colored fillings that could not be distinguished from the surface of a natural tooth. “It's important for me,” Cheryl said.
Lots of dental patients feel the same way, even if they don't spend time in front of television cameras. That's why the dental profession has developed tooth-like materials such as composite resins and porcelains that mimic natural tooth material exactly. These materials are also suitable for children's teeth and can incorporate fluoride to reduce tooth decay. It's even possible to replace old silver-colored fillings with these newer dental materials.

Witnessing or being involved in a sports-related dental injury can be a scary event not only for the player, but also for onlookers even if the injuries turn out to be minor. However, knowing what to do — and more importantly — how quickly to react can make a radical difference to the outcome. This is just one reason why we want to share the following easy-to-remember guidelines for what, how and when you need to respond to various types of dental injuries.
- Immediate — within 5 minutes of the injury: If a permanent tooth is totally knocked out (avulsed), it requires immediate treatment by cleaning and re-implanting the tooth back into its original position to have any hope of saving the tooth long-term. Knocked out baby (primary) teeth are not reimplanted for fear of damage to underlying permanent teeth.
- Urgent — within 6 hours of the injury: If a permanent or primary tooth is still in the mouth but has been moved from its original position, it is considered an acute injury and should be treated within 6 hours.
- Less urgent — within 12 hours of the injury: If a permanent or primary tooth is broken or chipped but has not shifted from its original position, the injury is classified as less urgent. You still need to see a dentist for an exam; however, you generally can wait up to 12 hours before possible irreversible damage occurs.
