Teeth are naturally strong and durable — if we can prevent or control dental disease like tooth decay or gum disease, they can last a lifetime. Still, teeth do wear gradually as we age, a fact we must factor into our dental care as we grow older.
Sometimes, though, the wear rate can accelerate and lead to problems much earlier — even tooth loss. There are generally four ways this abnormal wear can occur.
Tooth to tooth contact. Attrition usually results from habitual teeth grinding or clenching that are well beyond normal tooth contact. Also known as bruxism, these habits may occur unconsciously, often while you sleep. Treatments for bruxism include an occlusal guard worn to prevent tooth to tooth contact, orthodontic treatment, medication, biofeedback or psychological counseling to improve stress coping skills.
Teeth and hard material contact. Bruxism causes abrasion when our teeth regularly bite on hard materials such as pencils, nails, or bobby pins. The constant contact with these and other abrasive surfaces will cause the enamel to erode. Again, learning to cope with stress and breaking the bruxism habit will help preserve the remaining enamel.
Chronic acid. A high level of acid from foods we eat or drink can erode tooth enamel. Saliva naturally neutralizes this acid and restores the mouth to a neutral pH, usually within thirty minutes to an hour after eating. But if you’re constantly snacking on acidic foods and beverages, saliva’s buffering ability can’t keep up. To avoid this situation, refrain from constant snacking and limit acidic beverages like sodas or sports drinks to mealtimes. Extreme cases of gastric reflux disease may also disrupt your mouth’s pH — seek treatment from your medical doctor if you’re having related symptoms.
Enamel loss at the gumline. Also known as abfraction, this enamel loss is often caused by receding gums that expose more of the tooth below the enamel, which can lead to its erosion. Preventing and treating gum disease (the leading cause of receding gums) and proper oral hygiene will lower your risks of receding gums and protect tooth enamel.

Boston Bruins defenseman Zdeno Chara had a rough Stanley Cup final against the St. Louis Blues this past June. Not only did the Bruins ultimately lose the championship, but Chara took a deflected puck shot to the face in Game Four that broke his jaw.
With the NHL season now over, the 42-year-old Bruins captain continues to mend from his injury that required extensive treatment. His experience highlights how jaw fractures and related dental damage are an unfortunate hazard in hockey—not only for pros like Chara, but also for an estimated half million U.S. amateurs, many in youth leagues.
Ice hockey isn't the only sport with this injury potential: Basketball, football (now gearing up with summer training) and even baseball players are also at risk. That's why appropriate protective gear like helmets and face shields are key to preventing injury.
For any contact sport, that protection should also include a mouthguard to absorb hard contact forces that could damage the mouth, teeth and gums. The best guards (and the most comfortable fit) are custom-made by a dentist based on impressions made of the individual's mouth.
But even with adequate protection, an injury can still happen. Here's what you should do if your child has an injury to their jaw, mouth or teeth.
Recognize signs of a broken jaw. A broken jaw can result in severe pain, swelling, difficulty speaking, numbness in the chin or lower lip or the teeth not seeming to fit together properly. You may also notice bleeding in the mouth, as well as bruising under the tongue or a cut in the ear canal resulting from jawbone movement during the fracture. Get immediate medical attention if you notice any of these signs.
Take quick action for a knocked-out tooth. A tooth knocked completely out of its socket is a severe dental injury. But you may be able to ultimately save the tooth by promptly taking the following steps: (1) find the tooth and pick it up without touching the root end, (2) rinse it off, (3) place it back in its socket with firm pressure, and (4) see a dentist as soon as possible.
Seek dental care. Besides the injuries already mentioned, you should also see a dentist for any moderate to severe trauma to the mouth, teeth and gums. Leading the list: any injury that results in tooth chipping, looseness or movement out of alignment.
Even a top athlete like Zdeno Chara isn't immune to injury. Take steps then to protect your amateur athlete from a dental or facial injury.

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.
