If you know anything about dental disease, then you know bacteria ranks high on the Usual Suspects list. Tooth decay gets its start from acid produced by bacteria; periodontal (gum) disease is often triggered by bacteria that infect the gums.
But the particular strains of bacteria that can cause dental disease are a small percentage of the 10,000-plus species inhabiting your mouth. The rest, numbering in the millions, are fairly benign—and some, as recent research is now showing, play a sizeable role in protecting your teeth and gums against other malicious bacteria, fungi and viruses.
Dr. Aaron Weinberg, a dental researcher at Case Western Reserve University, has been investigating these protective bacteria for many years. His research began with a scientific conundrum: although the mouth has one of the highest densities of bacterial populations, wounds in the mouth tend to heal quickly.
The answer, he believes, originates with human beta defensins (hBDs), substances produced by cells in the lining of the mouth that are natural antibiotics against disease. He has found that certain bacteria actually help stimulate their production.
This isn't just an interesting fact about the body's defenses and immune system. During his research, Dr. Weinberg was able to identify the agent within the bacteria that triggered hBD production. This has opened up a new line of research: The possibility that harnessing this agent might help assist in our treatment of infection by boosting the body's defensive capabilities.
For example, researchers have proposed including a form of the agent in toothpaste. Over time, this might stimulate hBD production and guard the mouth against the development of dental diseases like gum disease.
These possibilities all come from our increasing knowledge and understanding of the microscopic world around us, especially in our mouths. Bacteria are much more complex than we may have realized—not all are our enemies, and some are definitely our friends. Learning more may open up new ways to keep our teeth and gums healthy.
Sometimes, looking at old pictures can really bring memories back to life. Just ask Stefani Germanotta—the pop diva better known as Lady Gaga. In one scene from the recent documentary Five Foot Two, as family members sort through headshots from her teen years, her father proclaims: "Here, this proves she had braces!"
"If I had kept that gap, then I would have even more problems with Madonna," Lady Gaga replies, referencing an ongoing feud between the two musical celebrities.
The photos of Gaga's teenage smile reveal that the singer of hits like "Born This Way" once had a noticeable gap (which dentists call a diastema) between her front teeth. This condition is common in children, but often becomes less conspicuous with age. It isn't necessarily a problem: Lots of well-known people have extra space in their smiles, including ex-football player and TV host Michael Strahan, actress Anna Paquin…and fellow pop superstar Madonna. It hasn't hurt any of their careers.
Yet others would prefer a smile without the gap. Fortunately, diastema in children is generally not difficult to fix. One of the easiest ways to do so is with traditional braces or clear aligners. These orthodontic appliances, usually worn for a period of months, can actually move the teeth into positions that look more pleasing in the smile and function better in the bite. For many people, orthodontic treatment is a part of their emergence from adolescence into adulthood.
Braces and aligners, along with other specialized orthodontic appliances, can also remedy many bite problems besides diastema. They can correct misaligned teeth and spacing irregularities, fix overbites and underbites, and take care of numerous other types of malocclusions (bite problems).
The American Association of Orthodontists recommends that kids get screened for orthodontic problems at age 7. Even if an issue is found, most won't get treatment at this age—but in some instances, it's possible that early intervention can save a great deal of time, money and effort later. For example, while the jaw is still developing, its growth can be guided with special appliances that can make future orthodontic treatment go quicker and easier.
Yet orthodontics isn't just for children—adults can wear braces too! As long as teeth and gums are healthy, there's no upper age limit on orthodontic treatment. Instead of traditional silver braces, many adults choose tooth-colored braces or clear aligners to complement their more professional appearance.
So if your child is at the age where screening is recommended—or if you're unhappy with your own smile—ask us whether orthodontics could help. But if you get into a rivalry with Madonna…you're on your own.

“What can I do about my child's teeth grinding habit?”
It's a common question we get from many concerned parents. Their exasperation involves more than having to wake every night to the annoying sounds coming from their child's bedroom: they're also worried about any potential damage occurring to their teeth.
Teeth grinding and similar habits fall under the umbrella term “bruxism.” In basic terms, bruxism is the involuntary movement of the teeth and jaws not engaged in regular functions like chewing, speaking or swallowing. Bruxism is actually common among pre-adolescent children, considered by many healthcare professionals as normal behavior like thumb sucking.
It's not fully known why children grind their teeth, especially during sleep. Stress can play a part, but many believe it could also be related to immaturity on the part of the neuromuscular system that controls chewing. In some cases it could be linked to sudden arousals from sleep, particularly if the child is prone to airway obstruction causing sleep apnea. And there may be a link with certain medications, especially for hyperactivity disorders like attention deficit hyperactivity disorder (ADHD).
Most children eventually outgrow the habit. If it persists, though, it can contribute to teeth problems. Teeth can withstand a lot of biting force, but when chronically exposed to the higher than normal forces produced during teeth grinding they can begin to wear. Sodas, fruit juices, sports drinks or similar acidic beverages complicate matters because they increase mouth acid that can soften enamel. And besides dental issues, teeth grinding can also cause jaw problems, ear pain and headaches.
If symptoms begin to appear, we can take steps to reduce the effect of teeth grinding, such as a mouth guard worn at night to reduce biting forces and protect against wear. We can also look at curbing consumption of acidic foods and beverages, addressing possible airway obstructions, changing medications or counseling for psychological stress.
As with thumb sucking, there's no cause for immediate alarm if your children grind their teeth. But if it continues on into their later childhood years or begins to affect their health and well-being, we'll need to intervene to prevent further harm.
