Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.
“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”
The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”
A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.
It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.
So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!

Advanced tooth decay is a serious dental problem that can threaten an affected tooth's survival. But for decades now dentists have reliably used root canal treatment to better a decayed tooth's odds. This routine procedure performed with dental drill and special hand tools removes infected tissue inside a tooth and replaces the voids with a filling to prevent future infection.
But now there's a new way to perform a root canal—with a surgical laser. Lasers, amplified and focused light beams, aren't new to healthcare—they're an integral feature of many routine medical treatments and surgeries. But their use is relatively new to dentistry, and to endodontics (treating the interior of teeth) in particular.
Lasers can be used in root canal treatment to perform a number of tasks. They can remove diseased tissue and other debris from the innermost tooth pulp. They can be used to clean and shape root canal walls in preparation for filling. And they can also be used to soften and mold the filling material to fit more precisely within a tooth's particular root canal network.
Although laser-assisted root canal therapy isn't yet widespread, laser's limited use to date has given us a fair picture of both their advantages and disadvantages. As with other medical laser applications, lasers are very precise in removing diseased tissue without too much disruption of healthy tissue. There's less need for anesthesia than with dental drills, and lasers are a lot less noisy and jarring. Patients by and large experience less bleeding, as well as less discomfort or infection afterward.
But because laser light can only travel in a straight line, they're difficult to use in many tightly curved root canals. In these cases, the traditional methods are better suited, although a laser can be used in conjunction with other tasks. Temperature with lasers must also be carefully managed lest the high heat that's often generated damages natural tissues.
Although lasers won't be replacing traditional treatment methods for decayed teeth in the foreseeable future, there's hope they'll become more commonplace as technology and techniques continue to advance. Lasers can only improve what already is an effective means of saving teeth.

Losing a tooth affects not only your smile but your overall dental health too. A dental implant solves both issues: it replaces the whole tooth, including the root, to merge durability with a life-like appearance.
For teenagers with a missing tooth, however, an implant may not be a good idea, at least until they've physically matured. Although their permanent teeth have usually all come in by puberty, the jaws and facial structure continue to develop into early adulthood. An implant placed too early could appear misaligned when the jaw fully matures.
The best approach for teens is a temporary replacement until they're physically ready for an implant. There are two good options: a removable partial denture (RPD) or a fixed bonded bridge.
Common among adults, an RPD is also a viable replacement for a teenager's missing tooth. An RPD consists of a prosthetic (false) tooth set in a nylon or acrylic base that resembles gum tissue. Metal clips formed in the RPD fit over adjacent teeth to hold the appliance in place; this also makes it easy to remove for cleaning or sleep time. We typically recommend an acrylic base for teens because it's easier to adjust if the RPD's fit becomes loose.
To hold it in place, a traditional bridge uses crowns on either side of the replacement tooth to bond over the natural teeth next to the open socket. Because this requires permanently altering the support teeth, we recommend a bonded bridge that doesn't.
This modified bridge uses wing-like strips of dental material on the back of the false tooth that project outward. With the tooth in place, we bond the extending portions of these projections to the back of the adjacent teeth, which secures the false tooth in place.
Of the two options, the bonded bridge is more comfortable, buys the most time and looks the most natural. But it will cost more than an RPD. Bite issues, teeth grinding, overall gum health or your child's level of hygiene conscientiousness could also nix it as a viable option.
Either choice will effectively replace your child's missing tooth until it's time for a permanent restoration. We'll help you weigh all the factors to determine which one is best for your situation.
The Golden Globes ceremony is a night when Hollywood stars shine their brightest. At the recent red-carpet event, leading man Viggo Mortensen had plenty to smile about: Green Book, the movie in which he co-starred, picked up the award for Best Motion Picture—Musical or Comedy. But fans looking at the veteran actor's big smile today might not realize that it once looked very different. A few years ago, an accident during the filming of The Two Towers took a major chip out of Mortensen's front tooth!
That might be OK for some movies (think The Hangover or Dumb and Dumber)—but it's not so great for everyday life. Fortunately, Mortensen visited a dentist promptly, and now his smile is picture-perfect. How was that accomplished? He didn't say…but generally, the best treatment for a chipped tooth depends on how much of the tooth's structure is missing.
If the tooth has only a small chip or crack, it's often possible to restore it via cosmetic bonding. This procedure can be done right in the dental office, frequently in a single visit. Here's how it works: First the tooth is cleaned and prepared, and then a tooth-colored resin is applied to the area being restored. After it is cured (hardened) with a special light, additional layers may be applied to build up the missing structure. When properly cared for, a tooth restored this way can look good for several years.
For a longer-lasting restoration, veneers may be recommended. These are wafer-thin shells made of durable material (most often porcelain) that cover the front (visible) surfaces of teeth. Strong and lifelike, veneers can match the exact color of your natural teeth—or give you the bright, high-wattage smile you've always wanted. No wonder they're so popular in Hollywood! Because veneers are custom-made for you, getting them may require several office visits.
If a chip or crack extends to the inner pulp of the tooth, a root canal procedure will be needed to keep the tooth from becoming infected—a situation that could have serious consequences. But you shouldn't fear a root canal! The procedure generally causes no more discomfort than filling a cavity (though it takes a little longer), and it can help save teeth that would otherwise be lost. After a root canal, a crown (cap) is generally needed to restore the visible part of the tooth.
When a damaged tooth can't be restored, it needs to be extracted (removed) and replaced. Today's best option for tooth replacement is a dental implant—a small, screw-shaped post inserted into the bone of your jaw that anchors a lifelike, fully functional crown. Implants require very little special care and can look great for many years, making them a top choice for tooth replacement
