Like the rest of healthcare, antibiotics have transformed dentistry. Advanced oral infections that once eluded successful treatment are routinely stopped with the use of these “wonder drugs.” But their overuse over the years has given rise to dangerous “superbugs” resistant to many antibiotics.
Antibiotics are one of the 20th Century's most significant healthcare achievements. Drugs like penicillin played a major role ending the global threat of tuberculosis, cholera and bacterial meningitis. Over the last few decades, more antibiotics have been developed to defend against an even wider array of bacterial dangers.
But along the way doctors and dentists began prescribing antibiotics for all manner of illnesses including viral infections like colds or flu for which they're less effective. They've also been increasingly used as a preventive measure, including inclusion in animal feed to fight disease.
But our tiny biological nemeses are adaptable. As bacterial strains come in contact with greater amounts of antibiotics, individual bacterium that survive transmit their resistance to subsequent generations. This can produce new strains like Staphylococcus aureus (MRSA) that are resistant to methicillin and other common antibiotics that once contained them.
There's deep concern that these new resistant strains, often recent incarnations of old diseases once thought defeated, will lead to higher rates of sickness and death. Increasing resistance could also make common procedures like those performed by dentists and oral surgeons, much riskier to undertake.
To combat this, pharmaceutical companies are racing to create new drugs to compensate. Recently, they've received an encouraging sign of hope in this battle from an unlikely source: viruses. Researchers in Tel Aviv, Israel have discovered an antagonistic protein to bacteria among a group of viruses called bacteriophages. The protein, injected into a bacterium, commandeers the cell's DNA function to aid virus reproduction, which kills the host.
In the words of one researcher, this makes these particular “enemy of our enemy” viruses our “friend.” Although the discovery is still a long way from practical use in antibiotics, harnessing it in future drug versions could help pack a greater punch against resistant bacteria.
In the meantime, providers and patients alike must practice and advocate for stricter protocols regarding the use of antibiotics. The viability of tomorrow's healthcare is on the line.
Although dental care is our primary focus, we dentists are also on the lookout for other health problems that may manifest in the mouth. That's why we're sometimes the first to suspect a patient may have an eating disorder.
Eating disorders are abnormal dietary patterns that can arise from mental or emotional issues, the most common being anorexia nervosa and bulimia nervosa. Each has different behaviors: Anorexics abnormally restrict their food intake (“self-starvation”), while bulimics typically eat heavily and then induce vomiting (“binge and purge”).
Although bulimics are more likely to binge and purge, anorexics may also induce vomiting. That practice in particular can leave a clue for dentists. While vomiting, powerful stomach acid enters the mouth, which can then soften and erode tooth enamel.
It's the pattern of erosion a dentist may notice more than the erosion itself that may indicate an eating disorder. A person while vomiting normally places their tongue against the back of the lower teeth, which somewhat shields them from acid. The more exposed upper teeth will thus tend to show more erosion than the bottom teeth.
A dentist may also notice other signs of an eating disorder. Enlarged salivary glands or a reddened throat and tongue could indicate the use of fingers or objects to induce vomiting. Lack of oral hygiene can be a sign of anorexia, while signs of over-aggressive brushing or flossing may hint of bulimia.
For the sake of the person's overall well-being, the eating disorder should be addressed through professional counseling and therapy. An excellent starting point is the website nationaleatingdisorders.org, sponsored by the National Eating Disorders Association.
The therapy process can be lengthy, so patients should also take steps to protect their teeth in the interim. One important measure is to rinse out the mouth following purging with a little baking soda mixed with water. This will help neutralize oral acid and reduces the risk of erosion. Proper brushing and flossing and regular dental visits can also help prevent dental disease.
An eating disorder can be traumatic for both patients and their families, and can take time to overcome. Even so, patients can reduce its effect on their dental health.

A scoop of ice cream is one of life's little pleasures. But for one in three Americans, it could be something altogether different—an excruciating pain when cold ice cream meets teeth. This short but painful experience that can happen when dental nerves encounter hot or cold temperatures is called tooth sensitivity.
A look at tooth anatomy will help explain why. Teeth are mainly composed of outer enamel, a layer of nerves and blood vessels within the tooth called the pulp, and dentin, a porous layer in between. The pulp nerves pick up temperature and pressure sensations from outside the teeth through a network of tiny passageways (tubules) in the dentin. Enamel muffles these sensations before traveling the tubules, which prevents overstimulation of the nerves.
This careful balance can be disrupted, however, if the enamel becomes eroded by acid from foods or beverages, or as a byproduct of bacteria. This exposes the underlying dentin to the full brunt of outward sensations, which can then impact the nerves and cause them to overreact.
This hyper-sensitivity can also occur around the tooth roots, but for a different reason. Because the gums primarily protect this area rather than enamel, the roots can become hyper-sensitive if they lose gum coverage, a condition known as gum recession caused mainly by gum disease or over-aggressive hygiene.
Besides using dental products that block nerve sensation, reducing sensitivity largely depends on addressing the underlying cause. If gum disease, the focus is on removing plaque, a bacterial film on dental surfaces that causes and sustains the disease. Stopping an infection allows the gums to heal and hopefully regain their original teeth coverage. More advanced cases, though, may require grafting surgery to foster gum regeneration.
If the cause is enamel erosion or other results of decay or trauma, we can utilize a number of treatments depending on the extent of tooth damage including cavity filling, root canal therapy or crowning. As a last resort, we may need to remove a tooth that's beyond reasonable repair.
If you've begun to experience sensitive teeth, it's important that you see us as soon as possible. The earlier we can diagnose the cause, the less invasive we can be with treatments to ease or even stop this most unpleasant experience.

You're more apt to lose teeth because of periodontal (gum) disease and tooth decay than any other cause. But neither of these bacterial diseases have to happen: You can prevent them through daily brushing and flossing and twice-a-year dental cleanings.
But that's not all: You can also boost your dental care practices by eating foods that strengthen and protect teeth. On the other hand, a poor diet could reduce the effectiveness of your oral hygiene practices in preventing tooth decay or gum disease.
A diet that might lead to the latter is often high in refined sugar (sucrose), often added to processed foods and snacks to improve taste. But sucrose is also a top food source for oral bacteria, increasing their numbers when it's readily available. A higher bacterial population greatly increases your risk for tooth decay or gum disease.
On the other hand, certain foods benefit your overall dental health. Fresh fruits and vegetables, for example, are filled with nutrients and minerals like vitamin D or calcium that strengthen teeth against disease. And although they can also contain natural sugars, these don't pose the same problems as added sucrose due to the plant fiber you consume with them.
Dairy foods can also help you maintain healthy teeth and gums. Milk and cheese contain minerals like calcium and phosphorus, and a protein called casein, all of which strengthen teeth against decay. The enzymes in cheese stimulate saliva, which in turn neutralizes mouth acid and prevent it from harming enamel.
Some foods are also natural sources of fluoride, a mineral that strengthens tooth enamel. One example is black tea, which also, along with green tea, contains antioxidants that protect against cancer.
The best strategy for “tooth-friendly” nutrition is to pursue a diet that's high in fiber-rich natural foods and low in sugar-added processed foods. In practice, you'll want most of your diet to consist of fresh fruits and vegetables and low-fat dairy food, while minimizing foods with added sugar.
Following this kind of diet will certainly benefit your overall health. But it will also make it easier for you to prevent dental disease and keep your teeth and gums healthy.

Tara Lipinski loves to smile. And for good reason: The Olympic-gold medalist has enjoyed a spectacular career in ladies' figure skating. Besides also winning gold in the U.S. Nationals and the Grand Prix Final, in 1997 Lipinski became the youngest skater ever to win a World Figure Skating title. Now a sports commentator and television producer, Lipinski still loves to show her smile—and counts it as one of her most important assets. She also knows the importance of protecting her smile with daily hygiene habits and regular dental care.
Our teeth endure a lot over our lifetime. Tough as they are, though, they're still vulnerable to disease, trauma and the effects of aging. To protect them, it's essential that we brush and floss every day to remove bacterial plaque—that thin accumulating film on teeth most responsible for tooth decay and gum disease.
To keep her smile in top shape and reduce her chances of dental disease, Lipinski flosses and brushes daily, the latter at least twice a day. She also uses a tongue scraper, a small handheld device about the size of a toothbrush, to remove odor-causing bacteria and debris from the tongue.
Lipinski is also diligent about visiting the dentist for professional cleanings and checkups at least twice a year because even a dedicated brusher and flosser like her can still miss dental plaque that can then harden into tartar. Dental hygienists have the training and tools to clear away any lingering plaque and tartar that could increase your disease risk. It's also a good time for the dentist to check your teeth and gums for any developing problems.
The high pressure world of competitive figure skating and now her media career may also have contributed to another threat to Lipinski's smile: a teeth-grinding habit. Teeth grinding is the unconscious action—often while asleep—of clenching the jaws together and producing abnormally high biting forces. Often a result of chronic stress, teeth grinding can accelerate tooth wear and damage the gum ligaments attached to teeth. To help minimize these effects, Lipinski's dentist created a custom mouthguard to wear at night. The slick plastic surface of the guard prevents the teeth from generating any damaging biting forces when they clench together.
The importance of an attractive smile isn't unique to celebrities and media stars like Tara Lipinski. A great smile breeds confidence for anyone—and it can enhance your career, family and social relationships. Protect this invaluable asset with daily oral hygiene, regular dental visits and prompt treatment for disease or trauma.
