Say “bacteria,” especially in the same sentence with “disease” or “infection,” and you may trigger an immediate stampede for the hand sanitizer. The last thing most people want is to come in contact with these “menacing” microorganisms.
If that describes you, however, you’re too late. If you’re of adult age, there are already 100 trillion of these single-celled organisms in and on your body, outnumbering your own cells 10 to 1. But don’t panic: Of these 10,000-plus species only a handful can cause you harm—most are either harmless or beneficial, including in your mouth.
Thanks to recent research, we know quite a bit about the different kinds of bacteria in the mouth and what they’re doing. We’ve also learned that the mouth’s microbiome (the interactive environment of microscopic organisms in a particular location) develops over time, especially during our formative years. New mothers, for example, pass on hundreds of beneficial species of bacteria to their babies via their breast milk.
As our exposure to different bacteria grows, our immune system is also developing—not only fighting bacteria that pose a threat, but also learning to recognize benevolent species. All these factors over time result in a sophisticated, interrelated bacterial environment unique to every individual.
Of course, it isn’t all sweetness and light in this microscopic world. The few harmful oral bacteria, especially those that trigger tooth decay or periodontal (gum) disease, can cause enormous, irreparable damage to the teeth and gums. It’s our goal as dentists to treat these diseases and, when necessary, fight against harmful microorganisms with antibacterial agents and antibiotics.
But our growing knowledge of this “secret world” of bacteria is now influencing how we approach dental treatment. A generalized application of antibiotics, for example, could harm beneficial bacteria as well as harmful ones. In trying to do good we may run the risk of disrupting the mouth’s microbiome balance—with adverse results on a patient’s long-term oral health.
The treatment strategies of the future will take this into account. While stopping dental disease will remain the top priority, the treatments of the future will seek to do it without harming the delicate balance of the mouth’s microbiome.

If you wince in pain while eating or drinking something hot or cold, you’re not alone: tooth sensitivity afflicts one in three Americans. To understand what’s possibly going on, let’s look first at tooth anatomy.
Teeth are mainly composed of three layers: an outer protective enamel that covers the upper crown, a middle layer called dentin and an inner pulp. The dentin is composed of small tubules that transmit outer temperature and pressure sensations to nerves in the pulp.
The enamel serves as a “muffler,” damping sensations to protect the nerves from overload. In the root area, the gums and a thin material called cementum covering the roots also help muffle sensation.
But sometimes teeth can lose this muffling effect and the nerves encounter the full brunt of the sensations. The most common reason is gum recession, usually caused by periodontal (gum) disease. The gums have shrunk back or “receded,” and after a short while the cementum covering will also be lost, exposing the dentin in the root area.
Another problem is enamel erosion caused by mouth acid. Chronic high acidity, often caused by bacterial growth or acidic foods and beverages, can dissolve the enamel’s mineral content, causing decay and exposure as well of the underlying dentin.
To avoid future tooth sensitivity, it pays to prevent these two dental problems. The most important thing you can do is practice daily brushing and flossing to reduce bacterial plaque and see your dentist regularly for dental cleanings and checkups.
But if you’re already experiencing symptoms, you’ll first need an accurate diagnosis of the cause. If it’s related to gum disease, immediate treatment could help stop or even reverse any gum recession. To address enamel erosion, your dentist may be able to protect and strengthen your teeth with sealants and topical fluoride.
There are also things you and your dentist can do to reduce your symptoms. One is for you to use hygiene products with fluoride, which can take the edge off of sensitivity, or potassium, which helps reduce nerve activity. Your dentist can further reduce nerve sensitivity by blocking the tubules with sealants and bonding agents.
Tooth sensitivity is an irritating problem in itself; more importantly, though, it’s often a warning of something else seriously wrong that needs attention. If you’re feeling a little sensitive in the teeth, see your dentist as soon as possible.

If there's anything that makes Alfonso Ribeiro happier than his long-running gig as host of America's Funniest Home Videos, it's the time he gets to spend with his family: his wife Angela, their two young sons, and Alfonso's teenaged daughter. As the proud dad told Dear Doctor–Dentistry & Oral Health magazine, "The best part of being a father is the smiles and the warmth you get from your children."
Because Alfonso and Angela want to make sure those little smiles stay healthy, they are careful to keep on top of their kids' oral health at home—and with regular checkups at the dental office. If you, too, want to help your children get on the road to good oral health, here are five tips:
- Start off Right—Even before teeth emerge, gently wipe baby's gums with a clean, moist washcloth. When the first teeth appear, brush them with a tiny dab of fluoride on a soft-bristled toothbrush. Schedule an age-one dental visit for a complete evaluation, and to help your child get accustomed to the dental office.
- Teach Them Well—When they're first learning how to take care of their teeth, most kids need a lot of help. Be patient as you demonstrate the proper way to brush and floss…over and over again. When they're ready, let them try it themselves—but keep an eye on their progress, and offer help when it's needed.
- Watch What They Eat & Drink—Consuming foods high in sugar or starch may give kids momentary satisfaction…but these substances also feed the harmful bacteria that cause tooth decay. The same goes for sodas, juices and acidic drinks—the major sources of sugar in many children's diets. If you allow sugary snacks, limit them to around mealtimes—that gives the mouth a chance to recover its natural balance.
- Keep Up the Good Work—That means brushing twice a day and flossing at least once a day, every single day. If motivation is an issue, encourage your kids by letting them pick out a special brush, toothpaste or floss. You can also give stickers, or use a chart to show progress and provide a reward after a certain period of time. And don't forget to give them a good example to follow!
- Get Regular Dental Checkups—This applies to both kids and adults, but it's especially important during the years when they are rapidly growing! Timely treatment with sealants, topical fluoride applications or fillings can often help keep a small problem from turning into a major headache.
Bringing your kids to the dental office early—and regularly—is the best way to set them up for a lifetime of good checkups…even if they're a little nervous at first. Speaking of his youngest child, Alfonso Ribeiro said "I think the first time he was really frightened, but then the dentist made him feel better—and so since then, going back, it's actually a nice experience." Our goal is to provide this experience for every patient.
If you have questions about your child's dental hygiene routine, call the office or schedule a consultation. You can learn more in the Dear Doctor magazine article “How to Help Your Child Develop the Best Habits for Oral Health.”
