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.

There are few things sweeter to hear than for your dentist to tell you your periodontal (gum) disease is under control. Depending on how deep the infection may have advanced, your treatment journey may have been a long one.
Unfortunately, while the battle may be over, the threat still lingers—once you've experienced a gum infection, you're at higher risk for a recurrence. To minimize that risk, you may need to undergo dental cleanings on a more frequent basis than before.
The average patient typically sees their dentist for cleanings every six months. The aim of these visits is to remove dental plaque, a thin film of bacterial-laden particles that is the prime source for gum disease. These cleanings are meant to supplement a daily habit of brushing and flossing, which should remove the bulk of plaque that builds up throughout the day.
After gum disease treatment, though, you may need to have these cleanings more frequently, and of a more involved nature than the normal cleaning. For patients who've overcome advanced gum disease, that frequency could initially be every other week, every couple of months or every three months. This frequency may change depending on the status of your gum health.
Besides a thorough cleaning, a specialized periodontal maintenance visit may include other interventions. For example, your dentist may apply topical antibiotics or other anti-bacterial products to keep bacterial growth under control.
Protecting you from further gum infection isn't totally on your dentist's shoulders—you also have a role to play. You'll need to brush and floss your teeth thoroughly every day, along with using any other hygiene products prescribed or recommended by your dentist. Daily hygiene will help prevent the buildup of dental plaque and subsequent bacterial growth.
You'll also need to keep a watchful eye on your gums for any emerging signs of infection. If you begin to notice swelling, pain or bleeding, contact your dentist as soon as possible to initiate remedial treatment.
Gum disease treatment can bring your gums back to a reasonable state of good health. But that state could be reversed with a returning gum infection. Only vigilance practiced by both you and your dentist can stop that from happening.
Self-improvement is an estimated $10 billion annual market—smartphone apps, one-on-one coaching and, of course, books that instruct and inspire people on everything from selling yourself to increasing your self-esteem. But as helpful as these resources might be, don't overlook the self-improvement opportunities that could be awaiting you at a familiar place: your dentist's office.
Cosmetic dental techniques can enhance more than your physical attributes. Because of the importance of smiling in everyday life, improving the appearance of your teeth and gums can fill you with a renewed sense of confidence. A transformed smile might just be a game changer in social and career settings, not to mention your romantic life.
Many cosmetic techniques also improve oral health. It's a double benefit! A more attractive smile is more likely to be a healthy smile.
So, in recognition of Self Improvement Month this September, here are 4 ways you could improve your smile appearance.
Teeth whitening. One of the simplest and most affordable ways to improve your smile appearance is with a teeth-whitening procedure. Years of eating, drinking and (for some) tobacco use can leave teeth yellowed and dull. A professional whitening can brighten your teeth and take years off your smile. With proper care and occasional touch-ups, your brighter, more attractive smile could last for years.
Dental veneers. Chipped, discolored or slightly gapped teeth can detract from an otherwise beautiful smile. Dental veneers could completely change all that. Thin wafers of dental porcelain, veneers bond to the front of teeth and mask all manner of imperfections. And because they're custom designed and colored to blend with other teeth, only you and your dentist need know you're wearing them.
Dental implants. Missing tooth gaps, especially in the visible "smile zone," stand out like a sore thumb. Dental implants, the premier method for tooth replacement, can fill those unsightly gaps and restore your smile. Implants are titanium metal posts imbedded in the jaw that develop strong attachments with the bone. This makes them durable and long-lasting for a truly life-like result.
Orthodontics. Realigning teeth through braces or removable clear aligners is first and foremost therapeutic—it's primarily performed to improve overall dental health. But a huge secondary benefit is a more attractive display of perfectly aligned teeth. That's why orthodontics is widely regarded as the "Original Smile Makeover."
To see if any of these or other procedures—or a combination of them—could transform your smile, make an appointment with us for an exam and consultation. Self-improvement might actually be as close as your teeth.
At what age should you begin treating a poor bite? Many might say with braces around late childhood or early adolescence. But some bite problems could be addressed earlier—with the possibility of avoiding future orthodontic treatment.
A crossbite is a good example. In a normal bite, all of the upper teeth slightly cover the lower when the jaws are shut. But a crossbite occurs when some of the lower teeth, particularly in back, overlap the upper teeth. This situation often happens when the upper jaw develops too narrowly.
But one feature of a child's mouth structure provides an opportunity to intervene and alter jaw development. During a child's early years, the palate (roof of the mouth) consists of two bones next to each other with an open seam running between them. This seam, which runs through the center of the mouth from front to back, will fuse during puberty to form one continuous palatal bone.
An orthodontist can take advantage of this separation if the jaw isn't growing wide enough with a unique device called a palatal expander. This particular oral appliance consists of four, thin metal legs connected to a central mechanism. The orthodontist places the expander against the palate and then uses the mechanism to extend the legs firmly against the back of the teeth on both sides of the jaw.
The outward pressure exerted by the legs also widens the seam between the two palatal bones. The body will respond to this by adding new bone to the existing palatal bones to fill in the widened gap. At regular intervals, the patient or a caregiver will operate the mechanism with a key that will continue to widen the gap between the bones, causing more expansion of the palatal bones until the jaw has grown to a normal width.
The palatal expander is most effective when it's applied early enough to develop more bone before the seam closes. That's why it's important for children to undergo bite evaluation with an orthodontist around age 6. If it appears a bite problem is developing, early interventions like a palatal expander could slow or stop it before it gets worse.

After months or even years of radiation or chemotherapy, the words "cancer-free" is music to your ears. Your joy and relief, though, may be tempered by the toll these treatments can take on the rest of your body—including your mouth.
Both of these treatments can destroy healthy tissue along with targeted cancer cells. If the focus has been on the head and neck regions, they could damage the salivary glands to the point that they won't produce adequate saliva flow.
A lack of saliva can have a detrimental effect on your oral health. Saliva buffers and helps lower oral acid levels that soften and erode enamel and increase the likelihood of tooth decay. Saliva also supplies antibodies that fight disease-causing bacteria. Otherwise, bacteria—and the risk for disease—can rapidly grow.
If these or other scenarios occur, you may experience dental damage, even tooth loss. Fortunately, we can restore an injured smile in various ways, including dentures, bridges or dental implants. But we should also attempt to limit the potential damage by taking steps to prevent dental disease during cancer treatment.
The most important of these is to brush and floss daily. Everyone should practice these hygiene tasks to remove disease-causing dental plaque, regardless of their health status. But because some natural disease-fighting mechanisms in the mouth may be disrupted during either radiation or chemotherapy, it's even more important if you're a cancer patient.
It's equally important to maintain as much as possible regular dental visits during cancer treatment. Dental cleanings provided during these visits remove any residual plaque and tartar (hardened plaque), which further lowers your disease risk.
Your dentist can better monitor your overall dental condition during frequent visits and provide as much treatment as you can tolerate. They can also enhance your protection against disease by prescribing antibacterial mouthrinses, fluoride applications or products to boost saliva production.
Some teeth and gum problems may be unavoidable; in that case, you may need post-treatment dental care to restore your oral health as needed. But caring as much for your dental health as you're able during cancer treatment could help you realize a better outcome.
