Placing a dental implant within the jawbone requires a surgical procedure. For most people it’s a relatively minor affair, but for some with certain health conditions it might be otherwise. Because of their condition they might have an increased risk for a bacterial infection afterward that could interfere with the implant’s integration with the bone and lead to possible failure.
To lower this risk, dentists for many years have routinely prescribed an antibiotic for patients considered at high-risk for infection to take before their implant surgery. But there’s been a lively debate among health practitioners about the true necessity for this practice and whether it’s worth the possible side effects that can accompany taking antibiotics.
While the practice still continues, current guidelines now recommend it for fewer health conditions. The American Dental Association (ADA) together with the American Heart Association (AHA) now recommend antibiotics only for surgical patients who have prosthetic heart valves, a history of infective endocarditis, a heart transplant or certain congenital heart conditions.
But patients with prosthetic joint replacements, who were once included in the recommendation for pre-surgical antibiotics, are no longer in that category. Even so, some orthopedic surgeons continue to recommend it for their joint replacement patients out of concern that a post-surgical infection could adversely affect their replaced joints.
But while these areas of disagreement about pre-surgical antibiotics still continue, a consensus may be emerging about a possible “sweet spot” in administering the therapy. Evidence from recent studies indicates just a small dose of antibiotics administered an hour before surgery may be sufficient to reduce the risk of infection-related implant failure with only minimal risk of side effects from the drug.
Because pre-surgical antibiotic therapy can be a complicated matter, it’s best that you discuss with both the physician caring for your health condition and your dentist about whether you should undergo this option to reduce the infection risk with your own implant surgery. Still, if all the factors surrounding your health indicate it, this antibiotic therapy might help you avoid losing an implant to infection.

Tooth decay is a highly destructive dental disease, responsible along with periodontal (gum) disease for most adult tooth loss. And we become even more susceptible to it as we get older.
One form of decay that’s especially prominent among senior adults is a root cavity. Similar to a cavity in the crown (visible tooth), this form instead occurs at or below the gum line in the roots. They happen mainly because the roots have become exposed due to gum recession, a common consequence of periodontal (gum) disease and/or brushing too hard.
Exposed roots are extremely vulnerable to disease because they don’t have the benefit of protective enamel like the tooth crown, covered instead with a thin and less protective mineral-like material called cementum. Normally, that’s not a problem because the gums that would normally cover them offer the bulk of the protection. But with the gums receded, the roots must depend on the less-effective cementum for protection against disease.
Although we treat root cavities in a similar way to those in the crown by removing decayed structure and then filling them, there’s often an added difficulty in accessing them below the gum line. Because of its location we may need to surgically enter through the gums to reach the cavity. This can increase the effort and expense to treat them.
It’s best then to prevent them if at all possible. This means practicing daily brushing and flossing to remove bacterial plaque, the thin, built-up biofilm on teeth most responsible for both tooth decay and gum disease. You should also visit your dentist at least twice a year for professional cleanings and advanced prevention methods like topical fluoride to strengthen any at-risk teeth.
You should also seek immediate treatment at the first sign of gum disease to help prevent gum recession. Even if it has occurred, treating the overall disease could help renew gum attachment. We may also need to support tissue regeneration with grafting surgery.
Root cavities are a serious matter that could lead to tooth loss. But by practicing prevention and getting prompt treatment for any dental disease, you can stop them from destroying your smile.

A recent episode of “America’s Got Talent” featured an engaging 93-year-old strongman called The Mighty Atom Jr. The mature muscleman’s stunt: moving a full-sized car (laden with his octogenarian “kid brother,” his brother’s wife, plus Atom’s “lady friend”) using just his teeth. Grinning for host Howie Mandel, Atom proudly told the TV audience that his teeth were all his own; then he grasped a leather strap in his mouth, and successfully pulled the car from a standstill.
We’re pleased to see that the Atom has kept his natural teeth in good shape: He must have found time for brushing and flossing in between stunts. Needless to say, his “talent” isn’t one we’d recommend trying at home. But aside from pulling vehicles, teeth can also be chipped or fractured by more mundane (yet still risky) activities — playing sports, nibbling on pencils, or biting too hard on ice. What can you do if that happens to your teeth?
Fortunately, we have a number of ways to repair cracked or chipped teeth. One of the easiest and fastest is cosmetic bonding with tooth-colored resins. Bonding can be used to fill in small chips, cracks and discolorations in the teeth. The bonding material is a high-tech mixture of plastic and glass components that’s extremely lifelike, and can last for several years. Plus, it’s a procedure that can be done right in the office, with minimal preparation or discomfort. However, it may not be suitable for larger chips, and it isn’t the longest-lasting type of restoration.
When more of the tooth structure is missing, a crown (or cap) might be needed to restore the tooth’s appearance and function. This involves creating a replacement for the entire visible part of the tooth in a dental lab — or in some cases, right in the office. It typically involves making a model of the damaged tooth and its neighbors, then fabricating a replica, which will fit perfectly into the bite. Finally, the replacement crown is permanently cemented to the damaged tooth. A crown replacement can last for many years if the tooth’s roots are in good shape. But what if the roots have been dislodged?
In some cases it’s possible to re-implant a tooth that has been knocked out — especially if it has been carefully preserved, and receives immediate professional attention. But if a tooth can’t be saved (due to a deeply fractured root, for example) a dental implant offers today’s best option for tooth replacement. This procedure has a success rate of over 95 percent, and gives you a natural looking replacement tooth that can last for the rest of your life.
So what have we learned? If you take care of your teeth, like strongman Atom, they can last a long time — but if you need to move your car, go get the keys.

Starting college is one of life’s biggest transition moments, the first time many young people can truly say they’re on their own. Their freshman year can be both exhilarating and frightening.
The reason for this seeming dichotomy is that both exciting opportunities and harmful pitfalls abound in college life. One such pitfall that’s often overlooked involves dental health: it’s all too easy to neglect good habits and adopt bad ones. But while it may not seem as harmful as other dangers, inattention to your dental health could create consequences that plague you long after graduation.
But being diligent about dental care can help you avoid serious problems now and in the future. At the top of the list: brush and floss your teeth daily and continue seeing a dentist at least twice a year. Hopefully, your parents or guardians have trained you in these vital habits—and they’re definitely habits you should continue for the rest of your life.
Close in importance to good oral hygiene is a healthy diet. Besides eating primarily “natural” food—fresh fruits and vegetables and less-processed foods—you should also set limits on your sugar consumption. This carbohydrate is a primary food for disease-causing bacteria, so limiting as much as possible the sugar you eat to just meal times will lower your risk for tooth decay.
Another area in which you should tread wisely is alcohol consumption. Besides the obvious consequences of alcohol abuse, immoderate drinking can also cause dental problems. Alcohol (and smoking) tends to dry out the mouth, which can increase the levels of oral bacteria and in turn increase your risk of both tooth decay and periodontal (gum) disease.
Finally, avoid getting piercings involving the lips, mouth or tongue even if it’s the thing to do. Piercing hardware can chip teeth and contribute to the shrinking back of the gums (recession). And be sure you practice safe sex: unprotected sexual activity could expose you to viral infections that cause oral problems including cancer.
Your college years should be an exciting and memorable experience. By practicing these and other common sense dental habits, you’ll be sure to remember these years fondly.

The basics for treating tooth decay have changed little since the father of modern dentistry Dr. G.V. Black developed them in the early 20th Century. Even though technical advances have streamlined treatment, our objectives are the same: remove any decayed material, prepare the cavity and then fill it.
This approach has endured because it works—dentists practicing it have preserved billions of teeth. But it has had one principle drawback: we often lose healthy tooth structure while removing decay. Although we preserve the tooth, its overall structure may be weaker.
But thanks to recent diagnostic and treatment advances we’re now preserving more of the tooth structure during treatment than ever before. On the diagnostic front enhanced x-ray technology and new magnification techniques are helping us find decay earlier when there’s less damaged material to remove and less risk to healthy structure.
Treating cavities has likewise improved with the increased use of air abrasion, an alternative to drilling. Emitting a concentrated stream of fine abrasive particles, air abrasion is mostly limited to treating small cavities. Even so, dentists using it say they’re removing less healthy tooth structure than with drilling.
While these current advances have already had a noticeable impact on decay treatment, there’s more to come. One in particular could dwarf every other advance with its impact: a tooth repairing itself through dentin regeneration.
This futuristic idea stems from a discovery by researchers at King’s College, London experimenting with Tideglusib, a medication for treating Alzheimer’s disease. The researchers placed tiny sponges soaked with the drug into holes drilled into mouse teeth. After a few weeks the holes had filled with dentin, produced by the teeth themselves.
Dentin regeneration isn’t new, but methods to date haven’t been able to produce enough dentin to repair a typical cavity. Tideglusib has proven more promising, and it’s already being used in clinical trials. If its development continues to progress, patients’ teeth may one day repair their own cavities without a filling.
Dr. Black’s enduring concepts continue to define tooth decay treatment. But developments now and on the horizon are transforming how we treat this disease in ways the father of modern dentistry couldn’t imagine.
