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.

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.

Are your stained teeth bumming you out? There's good news—you can transform that dull and dingy smile yourself with a tooth whitening product.
There are dozens of over-the-counter whitening kits that allow you to brighten your own smile. Although not as controlled and long-lasting as a dentist's professional whitening, these DIY kits can still give you effective results.
But since these products involve chemical solutions that bleach tooth enamel, there's a common concern about their safety. Could you be harming your teeth by using a home whitening kit?
The answer is no—as long as you follow the manufacturer's directions for using the product. These kits have been formulated with a lower percentage of bleaching agent (usually 10% carbamide peroxide) than whitening solutions used by dentists. They've also been subjected to several clinical studies gauging both their effectiveness and safety.
That said, though, exceeding a product's recommended directions and frequency of use could cause you problems. If not used properly, a bleaching solution can erode tooth enamel—and this protective tooth layer doesn't grow back! As long as you whiten "within the lines," so to speak, you shouldn't encounter this kind of situation.
With that said, though, there are good reasons to consult your dentist before using a whitening product, or have them perform the whitening for you.
For one thing, an over-the-counter whitening product won't work if the staining originates from inside a tooth. It's wise, then, to have a dental examination first before using a whitening product to uncover this or any other underlying dental problems that should be addressed first.
You may also find a professional whitening will give you a more desirable result. A stronger professional bleaching solution under a dentist's expert control can produce a brighter, longer lasting smile than a home use product. A dentist may also be able to control the level of brightness better to help you achieve the smile effect you desire, from subtle white to ultra-bright.
Whichever way you go, your dentist can advise you on your options and make sure your teeth are in good shape for whitening. The end result can be a brighter smile—and a brighter mood.

Think dental implants only replace individual teeth? Think again—this premier technology can also support other kinds of restorations to provide better stability and comfort. And, they also help improve bone health when incorporated with any type of tooth replacement options, especially dentures.
Although traditional dentures have enjoyed a long, successful history as a tooth replacement solution, they can interfere with bone health. That’s because regular dentures fit in the mouth by resting on the bony ridges of the jaw, which has implications for the bone.
As living tissue, bone goes through a growth cycle with older bone cells dying and dissolving and newer cells forming to take their place. The teeth play a role in this growth cycle — the forces generated when we chew travel up through the teeth and help stimulate bone growth. When teeth go missing, however, so does this stimulus.
Traditional dentures can’t replace this missing stimulus. In fact, the constant pressure of dentures on the jaw may even accelerate bone loss. A sign this is happening occurs when the dentures’ once tight fit begins to loosen and they become uncomfortable to wear.
Implant-supported dentures can help eliminate this problem. We first surgically place a few implants in the jaw, the number determined by which jaw (the lower requires less) and whether the denture is removable or fixed. If removable, the denture has connective points that match the implant locations — you simply connect them with the implants. If fixed, the denture is screwed into the implants to hold it in place.
So, how does this help bone health? For one, the denture no longer puts as much pressure on the jaw ridges—the main support comes from the implants. And, the implants themselves encourage bone stimulation: The titanium in the implant has a special affinity with bone cells that naturally grow and adhere to its metal surface. This natural integration between implant and bone can stop bone loss and may even help reverse it.
If you’re interested in implant-supported dentures, you’ll first need to undergo a full dental exam with your dentist. These restorations aren’t appropriate for all dental situations. But, if they can work for you, you may be able to enjoy the benefits of an implant-supported restoration.

Getting dental implants is going to require surgery. But don't let that concern you—it's a relatively minor procedure.
Currently the “gold standard” for tooth replacement, an implant consists of a titanium post surgically imbedded in the jawbone. We can affix a life-like crown to a single implant or support a fixed bridge or removable denture using a series of them.
Because placement will determine the restoration's final appearance, we must carefully plan implant surgery beforehand. Our first priority is to verify that you have adequate jawbone available to support an implant.
Additionally, we want to identify any underlying structures like nerves or blood vessels that might obstruct placement. We may also develop a surgical guide, a retainer-like device placed in the mouth during surgery that identifies precisely where to create the holes or channels for the implants.
After numbing the area with local anesthesia, we begin the surgery by opening the gum tissue with a series of incisions to expose the underlying bone. If we've prepared a surgical guide, we'll place it in the mouth at this time.
We then create the channel for the insert through a series of drillings. We start with a small opening, then increase its size through subsequent drills until we've created a channel that fits the size of the intended implant.
After removing the implant from its sterile packaging, we'll directly insert it into the channel. Once in place, we may take an x-ray to verify that it's been properly placed, and adjust as needed. Unless we're attaching a temporary crown at the time of surgery (an alternate procedure called immediate loading), we suture the gums over the implant to protect it.
Similar to other dental procedures, discomfort after surgery is usually mild to moderate and manageable with pain relievers like acetaminophen or ibuprofen (if necessary, we can prescribe something stronger). We may also have you take antibiotics or use antibacterial mouthrinses for a while to prevent infection.
A few weeks later, after the bone has grown and adhered to the implant surface, you'll return to receive your new permanent crown or restoration. While the process can take a few months and a number of treatment visits, in the end you'll have new life-like teeth that could serve you well for decades.
