In the realm of dental restorations, not all crowns are alike. And, one type isn't necessarily superior to the others. One type of crown may work better for a particular tooth, while a different crown is better suited to another.
Therefore, knowing your options can help you make a more informed choice with your dentist regarding the best crown for your needs. Here, then, is a quick primer on the main types of dental crowns used today.
Metal crowns. Early in the last century, crowns made of gold, silver or other metals were the go-to dental restoration. Because of their strength and durability, metal crowns are still used today, mainly in back teeth that encounter heavy biting forces. Their drawback: They're decidedly not the color of natural teeth and so can stand out if they're placed in the visible "smile zone."
PFM crowns. The first crowns made with dental porcelain solved the appearance problem, but couldn't adequately handle biting forces as well as metal. Out of this came the porcelain fused to metal (PFM) crown, which contains an inner core of metal overlaid with tooth-colored porcelain. Providing both strength and life-likeness, PFM crowns were immensely popular until the mid-2000s.
All-Ceramic crowns. The development of porcelains more durable than earlier versions eventually dethroned the PFM (although the latter is still used today). Sixty percent of the crowns installed in recent years are all-ceramic, many reinforced with a strength material known as Lucite. Many all-ceramic crowns reaching the 15-year mark are still in place and functioning.
All of these crowns continue to be viable options for dental patients. The biggest factor in choosing one particular crown over another is the type of tooth involved and its location. As mentioned before, metal or PFM crowns are usually better for back teeth where durability is a higher priority than aesthetics. All-ceramics work well in high-visibility front teeth that normally encounter lighter biting forces than back teeth.
Regardless of which kind eventually caps your tooth, any of today's modern crowns will function as intended. But the best crown for you will be the one that both protects your tooth and enhances your smile.

Fans everywhere were recently saddened by the news of musical legend Eddie Van Halen's death. Co-founder and lead guitarist for the iconic rock group Van Halen, the 65-year-old superstar passed away from oral cancer.
Van Halen's rise to worldwide fame began in the 1970s with his unique guitar style and energetic performances, but behind the scenes, he struggled with his health. In 2000, he was successfully treated for tongue cancer. He remained cancer-free until 2018 when he was diagnosed with throat cancer to which he succumbed this past October.
Van Halen claimed the metal guitar picks he habitually held in his mouth caused his tongue cancer. It's more likely, though, that his heavy cigarette smoking and alcohol use had more to do with his cancers.
According to the American Cancer Society, most oral cancer patients are smokers and, as in Van Halen's case, are more likely to beat one form of oral cancer only to have another form arise in another part of the mouth. Add in heavy alcohol consumption, and the combined habits can increase the risk of oral cancer a hundredfold.
But there are ways to reduce that risk by making some important lifestyle changes. Here's how:
Quit tobacco. Giving up tobacco, whether smoked or smokeless, vastly lowers your oral cancer risk. It's not easy to kick the habit solo, but a medically supervised cessation program or support group can help.
Limit alcohol. If you drink heavily, consider giving up alcohol or limiting yourself to just one or two drinks a day. As with tobacco, it can be difficult doing it alone, so speak with a health professional for assistance.
Eat healthy. You can reduce your cancer risk by avoiding processed foods with nitrites or other known carcinogens. Instead, eat fresh fruits and vegetables with antioxidants that fight cancer. A healthy diet also boosts your overall dental and bodily health.
Practice hygiene. Keeping teeth and gums healthy also lowers oral cancer risk. Brush and floss daily to remove dental plaque, the bacterial film on teeth most responsible for dental disease. You should also visit us every six months for more thorough dental cleanings and checkups.
One last thing: Because oral cancer is often diagnosed in its advanced stages, be sure you see us if you notice any persistent sores or other abnormalities on your tongue or the inside of your mouth. An earlier diagnosis of oral cancer can vastly improve the long-term prognosis.
Although not as prevalent as other forms of cancer, oral cancer is among the deadliest with only a 60% five-year survival rate. Making these changes toward a healthier lifestyle can help you avoid this serious disease.

Our primary aim as dentists is to preserve teeth. There are times, however, when preserving a tooth is no longer worth the effort and we must recommend removing it. Fortunately, extracted teeth can be replaced with a functional and attractive restoration.
Today's top tooth-replacement option is the dental implant. Composed of a titanium metal post imbedded into the jawbone, a single dental implant can replace an individual tooth or a series of implants can support other restorations for multiple teeth. Besides being incredibly life-like, dental implants are highly durable and can last for decades.
But dental implants aren't an optimal choice for everyone. Their cost often matches their status as the premier tooth replacement method. And because they require a minimum amount of bone for proper implantation, they're not always feasible for patients with extensive bone loss.
But even if dental implants aren't right for you, and you want a fixed restoration rather than dentures, you still have options. What's more, they've been around for decades!
One is a bonded crown, which works particularly well for a tooth excessively damaged by decay, excessive wear or fractures. After removing all of the damaged portions and shaping the remaining tooth, we cement a life-like crown, custom created for that particular tooth, over the remaining structure.
Besides improving appearance, a crown also protects the tooth and restores its function. One thing to remember, though, is although the crown itself is impervious to disease, the remainder of the natural tooth isn't. It's important then to brush and floss around crowned teeth like any other tooth and see a dentist regularly for cleanings.
Dental bridges are a fixed solution for extracted teeth. It's composed of prosthetic teeth to replace those missing bonded together with supporting crowns on both ends. These crowned teeth are known as abutments, and, depending on how many teeth are being replaced, we may need to increase the number of abutments to support the bridge.
Although durable, crowns or bridges typically don't match the longevity of an implant. And, implants don't require the permanent alteration of support teeth as is necessary with a bridge. But when the choice of implants isn't on the table, these traditional restorations can be an effective dental solution.

It's normal to have occasional mouth dryness—that "cotton mouth" feeling when you first wake up or after eating a spicy meal. It soon dissipates, though, leaving you no worse for wear other than the memory of an unpleasant sensation.
For some, though, the unpleasant sensation becomes a chronic condition known as xerostomia, in which their mouth feels dry most of the time. And, it can have far-reaching consequences beyond a mere irritation if not treated.
Among the numerous causes for xerostomia, the most common appears to be over-the-counter and prescription medication. An estimated five hundred medications have dry mouth as a potential side-effect, from antihistamines to antidepressants. And because people over 65 are more likely to take medications, they also have a high occurrence of xerostomia.
A person with certain systemic diseases like Parkinson's Disease or undergoing radiation or chemotherapy for cancers of the head and neck may also encounter dry mouth. For example, an autoimmune disease called Sjögren's syndrome, primarily affecting postmenopausal women, can dry out the mouth's mucous membranes.
Chronic dry mouth isn't normal, and often a sign of a health problem that should be examined. And it can lead to more problems with your oral health. Because dry mouth is most likely a reduction in saliva, which helps buffer decay-causing acid and provides antibodies to fight bacteria, having less of this vital fluid can increase your risk for both tooth decay and gum disease.
So, what can you do if you're plagued by persistent dry mouth? If you suspect your medications may be a factor, talk with your doctor about whether one of them may be the underlying cause for your symptoms. You may be able to switch to an alternate medication without dry mouth side-effects.
You can also increase your water intake during the day, including drinking more before and after taking medication. And there are a number of products like the artificial sweetener xylitol found in gums and candies that can boost saliva. Your dentist may also be able to recommend products that increase saliva.
Above all, be sure you keep up daily brushing and flossing, as well as regular dental cleanings. Taking care of chronic dry mouth could help you avoid dental problems later.

Today's dentures are more comfortable, more functional and more life-like than ever before—so much so that you might forget you have them in. Even so, dentures do have some downsides, and constant wear only amplifies those.
Our biggest concern is the effect dentures can have on bone health. Older bone is constantly replaced by newer bone, and the forces generated while chewing help stimulate this new growth. When a tooth is lost, however, this growth stimulus vanishes with it for that area of the bone. This may result in a slower growth rate, which can eventually lead to lost bone volume and density.
Dentures can't restore this lost stimulus, and may even make the situation worse. That's because traditional dentures rest on the bony ridges of the gums where the teeth once were. This can put pressure on the underlying bone, which can accelerate bone loss—and even more so when wearers leave their dentures in continuously.
Dentures can also contribute to disease if they're not regularly removed and cleaned. Besides oral yeast infections, bacteria-laden dentures can contribute to the production of a protein called interleukin-6 produced by the white blood cells. If a significant amount of this protein passes into the blood stream, it can increase body-wide inflammation and foster a systemic environment conducive to serious diseases like pneumonia.
If you wear dentures, then, it's good for your health (oral and otherwise) to incorporate two practices into your daily life. The first is to remove your dentures at night while you sleep. Not only will this help slow the progression of bone loss, it will also give your gums a chance to rest and recover from denture wear.
It's also important to regularly clean your dentures, either with an antibacterial soap or a special denture cleanser. During storage, keep your dentures in clean water or a peroxide-based solution designed for dentures. This will reduce the accumulation of bacteria on your dentures that can cause disease.
Dentures restore the dental function and smile appearance that a person loses with their teeth. Taking care of your dentures (and giving your mouth a daily rest from them) will help promote good oral and general health for you and a longer life for your dentures.
