Dental crowns are an essential means for restoring damaged or unattractive teeth. A well-crafted crown not only functions well, it looks and blends seamlessly with the rest of the natural teeth.
Crowns are artificial caps that cover an entire visible tooth, often used for heavily decayed or damaged teeth or as added protection after a root canal treatment. Most crowns are produced by a dental lab, but some dentists are now creating them in-office with computer-based milling equipment. On the whole, the various crowns now available function adequately as teeth—but they can vary in their appearance quality.
In the early to mid 20th Century the all-metal crown was the standard; but while durable, it could be less than eye-pleasing. Although more life-like dental porcelain existed at the time, it tended to be brittle and could easily shatter under chewing stress.
Dentists then developed a crown that combined the strength of metal with the attractiveness of porcelain: the porcelain fused to metal or PFM crown. The PFM crown had a hollow, metal substructure that was cemented over the tooth. To this metal base was fused an outer shell of porcelain that gave the crown an attractive finish.
The PFM reigned as the most widely used crown until the mid 2000s. By then improved forms of porcelain reinforced with stronger materials like Lucite had made possible an all-ceramic crown. They’re now the most common crown used today, beautifully life-like yet durable without the need for a metal base.
All-ceramics may be the most common type of crown installed today, but past favorites’ metal and PFM are still available and sometimes used. So depending on the type and location of the tooth and your own expectations, there’s a right crown for you.
However, not all crowns even among all-ceramic have the same level of aesthetic quality or cost—the more life-like, the more expensive. If you have dental insurance, your plan’s benefits might be based on a utilitarian but less attractive crown. You may have to pay more out of pocket for the crown you and your dentist believe is best for you.
Whatever you choose, though, your modern dental crown will do an admirable, functional job. And it can certainly improve your natural tooth’s appearance.
Gum disease is a bigger problem than you might think. More than half of all adults over age 30 have it, and that figure jumps to 70% of adults over 65. If left untreated, gum (periodontal) disease can eventually loosen teeth and cause them to fall out. It can also cause health issues outside of the mouth, including an increased risk of heart disease and other systemic health conditions.
But the good news is that gum disease can be treated—and even better, prevented! Since September is National Gum Care Month, it’s a good time to answer some frequently asked questions about gum disease:
What causes gum disease?
Gum disease is caused by certain types of harmful oral bacteria that live in a sticky film called dental plaque that collects on teeth both above and below the gum line. If this film is not cleaned effectively each day, it can eventually harden into a substance called tartar that can only be removed by a dental professional. As your body tries to fight the bacteria and the toxins they produce, your gums can become inflamed and may start to pull away from the teeth. Eventually, bone beneath the gums can start to break down and with continued bone loss, the teeth could be lost.
How do I know if I have it?
Gum disease doesn’t always produce symptoms—especially in smokers. Smoking hides the symptoms of gum disease because nicotine reduces blood flow to the area. However, there are things you should look out for. Gingivitis, a mild form of gum disease, can produce red and/or puffy gums that bleed when you brush or floss. Signs of periodontitis, a more serious form of the disease, include gum recession, bad mouth odors or tastes, and tooth looseness. But the only way to truly know if you have gum disease is to come in for an exam.
What can I do about it?
If you have gingivitis, a professional teeth cleaning and a renewed commitment to oral hygiene at home—including daily flossing and rinsing with antibacterial mouthwash—may be all you need to turn the situation around. Periodontitis may require a variety of treatments, ranging from special cleaning procedures of the tooth root surfaces to gum surgery. The first step toward controlling gum disease is visiting the dental office for an exam.
How can I prevent it?
Regular professional teeth cleanings and meticulous oral hygiene at home are your best defenses against gum disease. Avoid sugary drinks and snacks—which feed the disease-causing bacteria in your mouth—and tobacco in all forms. If you have diabetes, do your best to manage it well because uncontrolled diabetes can worsen periodontal disease.
