Porcelain crowns have been used to restore problem teeth since at least the early 20th Century. Crown technology has gradually progressed from the early use of precious metals like gold or silver to more life-like porcelain crowns, often with a metal interior for added strength. Today, most crowns are all-porcelain, made with newer materials that not only look attractive but can endure under the pressures of daily chewing or biting.
While crowns are often part of restorations for missing teeth, they’re also commonly used to cap or fit over a viable tooth with structural or appearance problems. Here are 4 situations where a crown could improve a tooth’s form and function.
Traumatized teeth. A significant blow to the face or mouth could generate enough force to chip away or fracture a significant amount of structure from a tooth. If the root remains healthy and firmly attached within the jaw, however, a crown can replace the missing structure and restore the tooth’s function and appearance.
Root canal treatments. Root canal treatments remove infected or dead tissue within a tooth’s pulp chamber, its inner core, and the root canals. The procedure rescues the tooth but can in the process significantly alter the tooth’s structure and appearance. A crown not only restores the tooth but also provides added protection against further decay or tooth fracture.
Teeth with multiple fillings. We can effectively treat cavities caused by tooth decay by filling them. But with each filling we must remove more of the decayed structure and shape the cavity to accommodate the filling. After a number of times, a tooth may not have enough structure left to support another filling. If the tooth is still viable, a crown could solve this dilemma.
Abnormally developed teeth. Teeth sometimes don’t erupt in the jaw as they should and may be only partly visible. The tooth not only looks out of place but it can’t fully function like a normal tooth. Capping an abnormally developed tooth with a crown will help normalize it and allow it to blend in with surrounding teeth.

For anyone else, having a tooth accidentally knocked out while practicing a dance routine would be a very big deal. But not for Dancing With The Stars contestant Noah Galloway. Galloway, an Iraq War veteran and a double amputee, took a kick to the face from his partner during a recent practice session, which knocked out a front tooth. As his horrified partner looked on, Galloway picked the missing tooth up from the floor, rinsed out his mouth, and quickly assessed his injury. “No big deal,” he told a cameraman capturing the scene.
Of course, not everyone would have the training — or the presence of mind — to do what Galloway did in that situation. But if you’re facing a serious dental trauma, such as a knocked out tooth, minutes count. Would you know what to do under those circumstances? Here’s a basic guide.
If a permanent tooth is completely knocked out of its socket, you need to act quickly. Once the injured person is stable, recover the tooth and gently clean it with water — but avoid grasping it by its roots! Next, if possible, place the tooth back in its socket in the jaw, making sure it is facing the correct way. Hold it in place with a damp cloth or gauze, and rush to the dental office, or to the emergency room if it’s after hours or if there appear to be other injuries.
If it isn’t possible to put the tooth back, you can place it between the cheek and gum, or in a plastic bag with the patient’s saliva, or in the special tooth-preserving liquid found in some first-aid kits. Either way, the sooner medical attention is received, the better the chances that the tooth can be saved.
When a tooth is loosened or displaced but not knocked out, you should receive dental attention within six hours of the accident. In the meantime, you can rinse the mouth with water and take over-the-counter anti-inflammatory medication (such as ibuprofen) to ease pain. A cold pack temporarily applied to the outside of the face can also help relieve discomfort.
When teeth are broken or chipped, you have up to 12 hours to get dental treatment.Â Follow the guidelines above for pain relief, but don’t forget to come in to the office even if the pain isn’t severe. Of course, if you experience bleeding that can’t be controlled after five minutes, dizziness, loss of consciousness or intense pain, seek emergency medical help right away.
And as for Noah Galloway:Â In an interview a few days later, he showed off his new smile, with the temporary bridge his dentist provided… and he even continued to dance with the same partner!

So, you're about to have a tooth capped with a crown. Do you know what you need to know before you undergo this common dental procedure?
Here's a short true or false quiz to test your knowledge of dental crowns.
All crowns are the same. False — while all crowns have the same basic design — a life-like prosthetic tooth fitted over and bonded or cemented to a natural tooth — their compositions can vary greatly. Early metal crowns consisted mainly of gold or silver and are still used today. Porcelain-fused-to-metal (PFM) crowns — a metal interior for strength overlaid by a porcelain exterior for appearance — became popular in the latter 20th Century. Although still widely used, PFMs have been largely surpassed by newer all-ceramic materials that are stronger than past versions.
Crowns can differ in their artistic quality. True — all crowns are designed to replicate a natural tooth's function — in other words, enable the tooth to effectively chew again. But a crown's appearance can be a different story, depending on how much attention to detail and artistry goes into it. The higher the individual craftsmanship, the more lifelike it will appear — and the more expensive it can be.
With digital milling equipment, dental labs are obsolete. False — although technology exists that allows dentists to produce their own crowns, the equipment is not yet in widespread use. Â The vast majority of crowns are still produced by a trained technician in a dental laboratory. And just as you base your choice of a dentist on your confidence in and respect for them, dentists look for the same thing in a dental lab — good, reliable and consistent results.
Your insurance may not cover what your dentist recommends. True — dental insurance will typically pay for a basic, functional crown. Aesthetics — how it will look — is a secondary consideration. As a result, your policy may not cover the crown your dentist recommends to function properly and look attractive. A new crown, however, is a long-term investment in both your dental function and your smile. It may be well worth supplementing out of pocket your insurance benefit to get the crown that suits you on both counts.
It's no secret that many of Hollywood's brightest stars didn't start out with perfectly aligned, pearly-white teeth. And these days, plenty of celebs are willing to share their stories, showing how dentists help those megawatt smiles shine. In a recent interview with W magazine, Emma Stone, the stunning 28-year-old star of critically-acclaimed films like La La Land and Birdman, explained how orthodontic appliances helped her overcome problems caused by a harmful habit: persistent thumb sucking in childhood.
“I sucked my thumb until I was 11 years old,” she admitted, mischievously adding “It's still so soothing to do it.” Although it may have been comforting, the habit spelled trouble for her bite. “The roof of my mouth is so high-pitched that I had this huge overbite,” she said. “I got this gate when I was in second grade… I had braces, and then they put a gate.”
While her technical terminology isn't quite accurate, Stone is referring to a type of appliance worn in the mouth which dentists call a “tongue crib” or “thumb/finger appliance.” The purpose of these devices is to stop children from engaging in “parafunctional habits” — that is, behaviors like thumb sucking or tongue thrusting, which are unrelated to the normal function of the mouth and can cause serious bite problems. (Other parafunctional habits include nail biting, pencil chewing and teeth grinding.)
When kids develop the habit of regularly pushing the tongue against the front teeth (tongue thrusting) or sucking on an object placed inside the mouth (thumb sucking), the behavior can cause the front teeth to be pushed out of alignment. When the top teeth move forward, the condition is commonly referred to as an overbite. In some cases a more serious situation called an “open bite” may develop, which can be difficult to correct. Here, the top and bottom front teeth do not meet or overlap when the mouth is closed; instead, a vertical gap is left in between.
Orthodontic appliances are often recommended to stop harmful oral habits from causing further misalignment. Most appliances are designed with a block (or gate) that prevents the tongue or finger from pushing on the teeth; this is what the actress mentioned. Normally, when the appliance is worn for a period of months it can be expected to modify the child's behavior. Once the habit has been broken, other appliances like traditional braces or clear aligners can be used to bring the teeth into better alignment.
But in Stone's case, things didn't go so smoothly. “I'd take the gate down and suck my thumb underneath the mouth appliance,” she admitted, “because I was totally ignoring the rule to not suck your thumb while you're trying to straighten out your teeth.” That rule-breaking ended up costing the aspiring star lots of time: she spent a total of 7 years wearing braces.
Fortunately, things worked out for the best for Emma Stone: She now has a brilliant smile and a stellar career — plus a shiny new Golden Globe award!

Teeth grinding is one childhood habit that sounds worse than it usually is: often the most harm done is to your night’s sleep. That said, though, it’s still a habit to keep your eye on.
Also known as bruxism, teeth grinding is so common among children that it’s considered normal behavior by many healthcare professionals. As for causes, some suggest a child’s immature neuromuscular chewing control may trigger it, while others point to the change from deeper sleep to a lighter stage as a possible cause. Problems like airway obstruction, medications or stress also seem to contribute to the habit.
For most children, teeth grinding usually fades by age 11 with no adverse effect on their teeth. If the habit extends into adolescence, however, there’s an increased risk for damage, mainly tooth wear.
This can happen because grinding often produces chewing forces 20-30 times greater than normal. Over time this can cause the biting surfaces of the teeth to wear and reduces the size of the teeth. While teeth normally wear over a lifetime, accelerated wear can pose a significant health risk to your teeth. Any sign of tooth wear in a child or adolescent is definitely cause for concern.
If your child’s tooth grinding habit appears to be developing into a problem, your dentist may recommend a few treatment options. The most common is a thin, plastic night guard worn in the mouth during sleep that prevents the upper and lower teeth from making contact. If the suspected cause is airway obstruction, they may refer you to an ear, nose and throat (ENT) specialist to seek treatment for that, as well as other professionals to help with managing stress or medications.
Like thumb sucking, the habit of teeth grinding usually ends with no permanent ill effects. But if you notice it continuing late into childhood or your dentist finds tooth wear or other problems, take action to avoid problems long-term.
