Bacteria are bad… right? They can cause diseases like pneumonia, strep throat, and tooth decay. They are the reason we wash our hands with soap (or antibacterial gels) and cook (or refrigerate) our food. Yet it turns out that bacteria are also necessary to keep our bodies healthy — and new research is showing just how important these tiny microorganisms are to our well-being. Here are five facts you should know about bacteria.
The bacteria in our bodies outnumber our cells by a factor of 10 to 1. An estimated 100 trillion bacteria live inside the average human — but because they’re so small, they make up only 1-3 percent of our body mass.
The collection of bacteria we harbor is called our “microbiome.” Like the groundbreaking study of human DNA called the Human Genome Project, recent research is leading to a “map” of our bacterial makeup. This revolutionary study is called — you guessed it — the Human Microbiome Project.
No two people have exactly the same microbiome. But in general, the bacteria that live in a particular spot on the body (the mouth, for example) play the same roles in different individuals. Research has also shown that a healthy microbiome looks very different from a diseased microbiome.
In terms of bacteria, the mouth is one of the best-understood areas of the body. It has long been known that tooth decay can result when “bad” oral bacteria begin to outnumber their “good” counterparts. Now we are gaining a better understanding of how certain lifestyle factors — like cigarette smoking — may influence the bacterial balance in the mouth.
Understanding the microbiome may lead to new treatments for disease. Researchers hope that one day, certain serious diseases could be controlled by bacterial “transplants” that re-balance an individual’s microbiome. Maintaining a healthy microbiome could also help prevent many diseases.
So by all means, don’t stop brushing your teeth or washing your hands — this helps control bacteria that could harm you — but do remember that not all bacteria are harmful. One day, an infusion of bacteria might just cure your illness.
When Olympic figure skater Kristi Yamaguchi wanted to help her kids develop good oral health habits, the gold-medal-winner made good use of a family connection: Her father Jim Yamaguchi is a practicing dentist in the San Francisco Bay area who treats her entire brood. As she said in a recent interview, when she suspects the kids may be spending a little less effort on oral hygiene than they should, she playfully admonishes them: “You've got to brush your teeth better than that. Papa-san is going to know!”
Not all kids are lucky enough to have a grandpa who's a dentist — but every child can learn how to help take care of his or her oral health with age-appropriate techniques, plus plenty of parental guidance and encouragement. What's the best way to help your kids develop good oral hygiene routines? We're glad you asked!
Through babyhood and the toddler years, parents have the main responsibility for keeping kids' teeth clean. But as they begin to put away pacifiers and cease sucking thumbs — around ages 2 to 4 — children can also begin to help with their own oral hygiene routine. By then, kids will probably be used to the feel of gentle brushing, and may be eager to try it themselves.
A soft-bristled brush with a pea-sized dab of toothpaste is all they need to get started… along with a good dose of parental patience. Show them how to wiggle the brush back and forth from the gum line, and all around the upper and lower teeth, both in front and in back. At first, they will probably need plenty of help. But after the age of 6 or so, as their manual dexterity increases, so will their ability to get the job done.
You'll still have to check their work periodically — but you can also teach them how to do it on their own: Have your child run his or her tongue over the tooth surfaces. If they feel smooth and silky, they're probably clean too. If not… try, try again. This test is a good guideline to brushing effectiveness — but if you want to know for sure, use a temporary dye called a disclosing tablet (available at many drugstores) to reveal unseen buildups of plaque bacteria.
What else can you do to give your children the best chance at keeping a healthy mouth and sparkly teeth? Set a positive example! Make sure you (and your kids) eat a healthy diet, get moderate exercise, limit between-meal treats — and visit the dentist regularly. The encouragement you'll get after having a good dental checkup will make you feel like a gold medalist — even if the praise isn't coming from grandpa.

It’s rare now to encounter a news story about an infection spreading among a group of dental patients — a rarity thanks to the development of standards and procedures for infection control. As these standards have improved over the last few decades, the prevention of infection stemming from dental treatment has become more effective and easier to perform.
Like other healthcare providers, dentists are held (and hold themselves) to a high legal, moral and ethical standard to stop the spread of infection among their patients, and both governmental authorities and professional organizations mandate safety procedures. The United States Center for Disease Control regularly publishes recommendations for disinfection and sterilization procedures for all healthcare providers and facilities, including dental clinics. Dental and medical licensing bodies in each U.S. state also mandate control procedures and have made continuing education on infection control a condition of re-licensure.
For both medical and dental facilities, blood-borne pathogens represent the greatest risk of infection. These viral infections spread through an infected person’s blood coming in contact with the blood of an uninfected person, via a cut or a needle injection site. One of the most prevalent of these blood-borne diseases is hepatitis. This disease, which can severely impair the function of the liver and could be fatal, is caused by either of two viruses known as HBV and HCV. Any medical facility that encounters blood through needle injection or surgical procedures (including blood transfusion and surgical centers, and dental offices) must have a high degree of concern for controlling the spread of hepatitis and similar viral diseases.
Infection control protocols cover all aspects of potential exposure, including protective wear for workers and patients, proper disposal of contaminated refuse and disinfection of instruments and facilities. These comprehensive procedures not only keep patients safe from viral exposure, they also protect healthcare providers who experience greater exposure and risk for infection than the patients they serve.
Thanks to this strong emphasis on infection control, your dental visits are reliably safe. If you do have concerns, though, about the risk of infection during a dental visit, please let us know — we’ll be happy to discuss all we do to protect you and your family from infection.

Kids do lots of changing in the teen years, as bodies and minds begin the process of becoming more “grown up.” By now, parental reminders to brush teeth and go easy on sugary snacks might be met with rolled eyes and a groan. But there are still several ways that parents can help their teens to maintain good oral health.
1) Make sure kids get — and wear — a professionally made, custom-fitted mouthguard when playing sports.
The American Dental Association says athletes are 60 times more likely to suffer dental injury if they don't wear a mouthguard. These devices also protect the jaw, lips, cheeks, and tongue — not just the teeth. A mouthguard that's custom-made from a model of your child's teeth costs a little more, but offers greater protection than an off-the-shelf model.
2) Talk to your teens about the dangers of oral piercings.
Like tattoos and iPods, piercings are probably a sign of the times. But that doesn't make them harmless. Installing tongue and lip bolts creates a risk for the teeth and soft tissues that are nearby. Tooth chipping, sensitivity and pain, along with gum recession and infection, are some of the issues that may accompany an oral piercing. Remind teens that future dental problems may be a high price to pay for a fleeting fashion statement.
3) Get professional help if you — or your teen — develop an addiction to tobacco, alcohol or drugs, or an eating disorder.
Nobody wants to admit they aren't in control. But peer pressure, body image concerns and a host of other issues may lead teens into dangerous behaviors. The negative effect of various addictions on one's general health is well-documented; with respect to oral health, there are particular concerns. Tobacco not only stains the teeth, but causes changes in the mouth that can lead to oral cancer. Erosion of the tooth enamel is both a diagnostic signal of a potential eating disorder, and a problem that needs treatment. Don't hesitate to ask questions, particularly when an examination reveals a potential problem, and be sure to seek professional help when needed.

Since the time of the ancient Egyptians, people have used mixtures of various substances in pursuit of a single goal: cleaning their teeth effectively. Today, even with a glut of toothpaste tubes on the supermarket shelf, most people seem to have a particular favorite. But have you ever thought about what's in your toothpaste, and how it works? Here are five facts you might not know.
1) Most toothpastes have a very similar set of active ingredients.
Once upon a time, a toothpaste might have contained crushed bones and oyster shells, pumice, or bark. Now, thankfully, they're a little different: today's toothpaste ingredients generally include abrasives, detergents and fluoride compounds, as well as inert substances like preservatives and binders. Toothpastes formulated to address special needs, like sensitive teeth or tartar prevention, have additional active ingredients.
2) Abrasives make the mechanical action of brushing more effective
These substances help remove stains and surface deposits from teeth. But don't even think about breaking out the sandpaper! Modern toothpastes use far gentler cleaning and polishing agents, like hydrated silica or alumina, calcium carbonate or dicalcium phosphate. These compounds are specially formulated to be effective without damaging tooth enamel.
3) Detergents help break up and wash away stains
The most common detergent in toothpaste (which is also found in many shampoos) is sodium lauryl sulfate, a substance that can be derived from coconut or palm kernel oil. Like the abrasives used in toothpaste, these detergents are far milder than the ones you use in the washing machine. Yet they're effective at loosening the stains clinging to your teeth, which would otherwise be hard to dissolve.
4) Fluoride helps prevent tooth decay
This has been conclusively demonstrated since it was first introduced into toothpaste formulations in 1914. Fluoride — whether it's in the form of sodium fluoride, stannous fluoride or sodium monofluorophosphate (MFP) — helps strengthen tooth enamel and make it more resistant to acid attack, which precipitates tooth decay. In fact, it's arguably the most important ingredient, and no toothpaste can receive the American Dental Association's Seal of Approval without it.
5) Look for toothpaste with the ADA seal
This means that the particular brand of toothpaste has proven effective as a cleaning agent and a preventative against tooth decay. Plus, if the package says it has other benefits, then research has verified that it does what it says. Oh, and one other thing — toothpaste doesn't work if you don't use it — so don't forget to brush regularly!
