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.

Although adults are more prone to dental disease, children aren't immune from one particular infection, tooth decay. Some children, in fact, are at higher risk for an aggressive form called early childhood caries (ECC).
There are a number of things you can do to help your child avoid this destructive disease, especially daily brushing and flossing to remove bacterial dental plaque, the underlying cause for tooth decay. It's also important for your child to see a dentist regularly for professional dental cleanings and checkups.
But some of their teeth, particularly the back molars, may need some extra attention to fully protect them against decay. This is because larger teeth like molars have numerous pits and crevices along their biting surfaces that can accumulate dental plaque difficult to remove by brushing alone. The added plaque increases the presence of bacteria around the tooth, which increases the risk of decay.
To minimize this possibility, dentists can apply a dental sealant to "smooth out" those pits and crevices in the molars and make it more difficult for plaque to accumulate. This is a quick and painless procedure in which a dentist brushes a liquid plastic resin or similar material onto the teeth's biting surfaces. They then apply a curing light to harden it into a durable coating.
About one-third of children—mostly those considered at higher risk for tooth decay—have undergone sealant treatment. But the American Dental Association and the American Academy of Pediatric Dentistry recommend this preventive measure for all children between ages 5 and 7, and then later between 11 and 14 when additional molars come in. Although there is a moderate cost per tooth for sealant application, it's much less than the potential expense of treating an infected tooth.
Combined with daily oral hygiene and other preventive measures, sealants can reduce the chances of damaging tooth decay. Keeping your child's teeth healthy is an important part in maintaining their dental health today—and tomorrow.
How many actresses have portrayed a neuroscientist on a wildly successful TV comedy while actually holding an advanced degree in neuroscience? As far as we know, exactly one: Mayim Bialik, who plays the lovably geeky Amy Farrah Fowler on CBS' The Big Bang Theory… and earned her PhD from UCLA.
Acknowledging her nerdy side, Bialik recently told Dear Doctor magazine, “I'm different, and I can't not be different.” Yet when it comes to her family's oral health, she wants the same things we all want: good checkups and great-looking smiles. “We're big on teeth and oral care,” she said. “Flossing is really a pleasure in our house.”
How does she get her two young sons to do it?
Bialik uses convenient pre-loaded floss holders that come complete with floss and a handle. “I just keep them in a little glass right next to the toothbrushes so they're open, no one has to reach, they're just right there,” she said. “It's really become such a routine, I don't even have to ask them anymore.”
As many parents have discovered, establishing healthy routines is one of the best things you can do to maintain your family's oral health. Here are some other oral hygiene tips you can try at home:
Brush to the music — Plenty of pop songs are about two minutes long… and that's the length of time you should brush your teeth. If brushing in silence gets boring, add a soundtrack. When the music's over — you're done!
Flossing can be fun — If standard dental floss doesn't appeal, there are many different styles of floss holders, from functional ones to cartoon characters… even some with a martial-arts theme! Find the one that your kids like best, and encourage them to use it.
The eyes don't lie — To show your kids how well (or not) they are cleaning their teeth, try using an over-the-counter disclosing solution. This harmless product will temporarily stain any plaque or debris that got left behind after brushing, so they can immediately see where they missed, and how to improve their hygiene technique — which will lead to better health.
Have regular dental exams & cleanings — When kids see you're enthusiastic about going to the dental office, it helps them feel the same way… and afterward, you can point out how great it feels to have a clean, sparkling smile.
Braces are a common experience among teens and pre-teens. And although the treatment can be a major financial undertaking, more and more families pursue it to help their child attain a straighter, more attractive smile.
But orthodontics isn’t first and foremost a cosmetic treatment. Although an improved appearance is a benefit, the main reason for treatment is therapeutic—it can improve your child’s current and future dental health.
The teeth’s relationship to the jaws and gums makes moving them possible. Rather than simply being fixed within their jawbone socket, teeth are actually held in place by a strong, elastic tissue called the periodontal ligament. The ligament lies between the teeth and jawbone and attaches to both with tiny extending fibers. This attachment secures the teeth in place.
But the ligament also has a dynamic quality—it can reshape itself when necessary and allow teeth to move gradually into new positions. This is most necessary during the early years of mouth and jaw development, but it can also occur throughout life. Orthodontics takes advantage of this mechanism by applying precise pressure to the teeth in the direction of desired movement. The periodontal ligament does the rest by reshaping and allowing the teeth to move in response to this pressure.
The result is straighter teeth and a more normal bite. With the teeth now where they should be, it’s also easier to clean them of disease-causing dental plaque, whereas misaligned teeth are more prone to plaque accumulation that can be difficult to remove. And because the whole mouth including teeth are involved when we talk, teeth positioned in a more normal bite will improve speech.
Orthodontics is a long-term process, often encompassing more than the actual time wearing braces. Both orthodontists and pediatric dentists recommend a bite evaluation by an orthodontist around the age of 6. If it does appear an abnormal bite is forming, it may be possible to intervene and stop or at least slow the development. This could have a more positive impact on any future treatment.
Braces and other treatments can make a difference in your child’s self-image and social relationships. But the main beneficiary will be their dental health.

You're doing all the right things helping your child avoid tooth decay: daily brushing and flossing, regular dental visits and a low-sugar diet. But although occurrences are low, they're still getting cavities.
Some children still struggle with tooth decay even with proper dental care. If this is happening to your child, your dentist may be able to give them an extra preventive boost through topical fluoride.
Fluoride has long been recognized as a proven cavity fighter. Often added in small amounts to toothpastes and drinking water, fluoride strengthens tooth enamel against acid attacks that create cavities. With topical fluoride, a dentist applies a varnish, foam or gel containing a more concentrated amount of the chemical directly to the teeth.
The effectiveness of this method in reducing tooth decay is well-founded: A number of scientific studies involving thousands of children and adolescents found an average 28% reduction in occurrences of decay among those who received the treatment compared to those who didn't.
Still, many parents have concerns about the higher fluoride concentrations in topical applications. But even at this greater amount, fluoride doesn't appear to pose any long-term health risks. The most adverse effects—vomiting, headaches or stomach pain—usually occur if a child accidentally ingests too much of the solution during treatment.
Dentists, however, go to great lengths to prevent this by using guards to isolate the solution during an application. And in the case of a foam or gel application, parents can further lower the risk of these unpleasant side effects by not allowing their child to eat or drink for at least thirty minutes after the procedure.
The evidence seems to indicate that the benefits of regular topical fluoride applications for children at high risk outweigh the possible side effects. By adding this measure to your prevention strategy, you can further protect your child from this danger to their current and future dental health.
