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.
There are a lot of reasons (including a blow to the mouth) why one of your permanent teeth might become loose. The most common: advanced periodontal (gum) disease that has weakened the gum attachment to the tooth.
There's also another, less common reason: you have a grinding habit that's producing higher than normal biting forces. Besides accelerating tooth wear, the constant jaw movement and teeth clenching can stretch periodontal ligaments and loosen their attachment to a tooth.
If the gums are disease-free, teeth grinding is most likely the main culprit for the damage, what we call primary occlusal trauma. Our treatment goal here is to reduce the effect of the grinding habit and, if necessary, secure the teeth with splinting while the ligaments heal. We can often reduce the grinding effect with a custom bite guard worn while you sleep. We may also prescribe minor muscle relaxants and mild pain medication like aspirin or ibuprofen.
Sometimes we may need to perform other measures like re-shaping your teeth's biting surfaces so they don't generate as much biting force. You may also benefit from counseling or other psychological treatment to help you address and cope with stress, a prime driver for teeth grinding.
Even if you don't have a grinding habit, biting forces may still contribute to tooth looseness if you have advanced gum disease. Advanced disease results in excessive bone loss, which in turn reduces the remaining amount of ligaments attached to the tooth. This type of damage, known as secondary occlusal trauma, and ensuing tooth looseness can occur even when your biting forces are normal.
It's necessary in these cases to treat the gum disease, primarily by manually removing plaque and calculus (hardened plaque deposits), which causes and sustains the infection. Once removed, the gums can begin to heal and strengthen their attachment. We may also need to apply splinting or perform surgical procedures to encourage gum and bone reattachment.
Whatever has caused your loose tooth, our goal is to remove the cause or lessen its effects. With your tooth secure and the gums regaining their healthy attachment, we have a good chance of saving it.

What does November make you think of? Pumpkins? Turkeys? Dry leaves and frosty mornings? How about cigarette butts?
If you’re wondering about the last item, remember that November 15 is the date of the Great American Smokeout—a day set aside for those who want to take the first steps toward quitting the tobacco habit. While the percentage of smokers in the U.S. has dropped to less than 16% in recent years, according to the American Cancer Society there are still some 38 million Americans who smoke cigarettes. Smoking causes over 480,000 deaths every year, and is the leading preventable cause of death in the U.S.
Even if it doesn’t kill you, the effects of tobacco use can be devastating to your entire body—including your mouth. Whether you smoke cigarettes or use chewing tobacco, your risk of oral cancer is greatly increased, as is your chance of developing periodontal (gum) disease. What’s more, smoking can mask the symptoms of gum disease, so your condition is actually worse than it appears. Severe gum disease is one reason why smokers tend to lose more teeth than non-smokers.
In addition, because smoking interferes with the natural healing process, smokers have a much greater chance of dental implant failure. Tobacco use also can lead to increased amounts of plaque, which results in tooth decay and other oral health problems. It also stains your teeth, reduces your senses of smell and taste, and gives you bad breath.
Ready to quit yet? If so, there are lots of resources to help you on the road to a healthier life. The American Cancer Society, sponsor of the Smokeout, can help you make a plan to quit tobacco—and stay off it. It’s not easy, but over a million Americans do it every year. See their website for more information, plans and tips on quitting. Your health care professionals are also a great source of information and help when it’s time to get off the tobacco habit. Feel free to ask us any questions you may have.
And here’s the good news: The moment you quit, your body begins to recover from the effects of tobacco use. In just one year, you’ll have cut your risk of heart attack and stroke in half. After 5 to 15 years, your risk of stroke, coronary heart disease, and several other conditions is the same as someone who has never smoked.
