Among dental restorations, implants are the closest prosthetic we have to real teeth. They not only replace the visible crown, but the titanium post imbedded in the jawbone adequately substitutes for the tooth root. Because of their unique design, implants are not only life-like, they’re highly durable and could potentially last for decades.
But while their success rate is remarkably high (more than 95% exceed the ten-year mark), they can fail. Ironically, one possible cause for implant failure is periodontal (gum) disease. Although an implant’s materials are themselves impervious to disease, the tissues and underlying bone that support the implant aren’t. If these natural tissues become infected, the secure hold the implant has can weaken and fail.
A gum infection usually begins with dental plaque, a thin biofilm of bacteria and food particles that builds up on tooth surfaces. Certain strains of bacteria within plaque can infect the gums. One particular form of the disease known as peri-implantitis starts as an initial infection and ensuing inflammation of gum tissues around an implant. The disease can quickly spread down to the bone and destroy the integration between the bone and the implant that helps keep the implant in place.
That’s why it’s important for you to keep the implant and the tissues around it clean of plaque, just as you would the rest of your natural teeth. This requires daily brushing and flossing around the implant and other teeth, and visiting your dentist regularly for more thorough dental cleanings.
You should also be alert to any signs of disease, especially around implants: gum redness, swelling, bleeding or pus formation. Because of the rapidity with which peri-implantitis can spread, you should see your dentist as soon as possible if you notice any of these signs.
Preventing gum disease, and treating it promptly if it occurs, is a key part of implant longevity. Preserving your overall dental health will help make sure your implant doesn’t become a loss statistic.
Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.
Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.
A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.
During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.
Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.
As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.
If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.
During his former career as a professional footballer (that's a soccer star to U.S. sports fans) David Beckham was known for his skill at “bending” a soccer ball. His ability to make the ball curve in mid-flight — to avoid a defender or score a goal — led scores of kids to try to “bend it like Beckham.” But just recently, while enjoying a vacation in Canada with his family, “Becks” tried snowboarding for the first time — and in the process, broke one of his front teeth.
Some fans worried that the missing tooth could be a “red card” for Beckham's current modeling career… but fortunately, he headed straight to the dental office as soon as he arrived back in England. Exactly what kind of treatment is needed for a broken tooth? It all depends where the break is and how badly the tooth is damaged.
For a minor crack or chip, cosmetic bonding may offer a quick and effective solution. In this procedure, a composite resin, in a color custom-made to match the tooth, is applied in liquid form and cured (hardened) with a special light. Several layers of bonding material can be applied to re-construct a larger area of missing tooth, and chips that have been saved can sometimes be reattached as well.
When more tooth structure is missing, dental veneers may be the preferred restorative option. Veneers are wafer-thin shells that are bonded to the front surface of the teeth. They can not only correct small chips or cracks, but can also improve the color, spacing, and shape of your teeth.
But if the damage exposes the soft inner pulp of the tooth, root canal treatment will be needed to save the tooth. In this procedure, the inflamed or infected pulp tissue is removed and the tooth sealed against re-infection; if a root canal is not done when needed, the tooth will have an increased risk for extraction in the future. Following a root canal, a tooth is often restored with a crown (cap), which can look good and function well for many years.
Sometimes, a tooth may be knocked completely out of its socket; or, a severely damaged tooth may need to be extracted (removed). In either situation, the best option for restoration is a dental implant. Here, a tiny screw-like device made of titanium metal is inserted into the jaw bone in a minor surgical procedure. Over time, it fuses with the living bone to form a solid anchorage. A lifelike crown is attached, which provides aesthetic appeal and full function for the replacement tooth.
So how's Beckham holding up? According to sources, “David is a trooper and didn't make a fuss. He took it all in his stride." Maybe next time he hits the slopes, he'll heed the advice of dental experts and wear a custom-made mouthguard…

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 you’re buying a tool or appliance, you compare brands for the best quality you can afford. There’s another important item that deserves the same level of scrutiny: your toothbrush. Choosing the right one for you can make a huge difference in your oral hygiene effectiveness.
But a visit to your store’s dental care aisle can dim your enthusiasm. You have plenty of options involving all manner of shapes, sizes and features. Perhaps too many: After a while, the sheer number of choices can paralyze your decision-making process.
You can streamline this selection process by concentrating on a few important toothbrush basics. First up for consideration: the bristles. While you may think a good stiff brush would be best, it’s actually the opposite—most dental professionals recommend softer bristles. That’s because hard bristles can potentially damage your teeth and gums over time.
Softer bristles are gentler on your teeth and just as effective for removing plaque, if you use the right technique and thoroughly brush all tooth surfaces. And look for rounded bristles, which are friendlier to your gums.
Next, look for a brush that feels right in your hand. If you have problems with manual dexterity, look for one with an oversized handle. Some brushes come with angled necks and tapered heads, which you may find effective in reaching less accessible back teeth. This might mean trying different brushes until you get one that’s right for you. Don’t worry, though, you’re not buying a brush for life—in fact, you should change out your brush every three to six months.
You’ll also rarely go wrong buying a toothbrush with the American Dental Association Seal of Acceptance on the packaging. This seal signifies the toothbrush has undergone testing and met the ADA’s standards for hygiene effectiveness. While some manufacturers of effective brushes don’t pursue this seal, you can be sure one with it has passed the test of quality.
It makes all the difference in the world having the right tool for the job. Be sure your toothbrush is the right one for you.
