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.
Professional Hockey player Keith Yandle is the current NHL “iron man”—that is, he has earned the distinction of playing in the most consecutive games. On November 23, Yandle was in the first period of his 820th consecutive game when a flying puck knocked out or broke nine of his front teeth. He returned third period to play the rest of the game, reinforcing hockey players’ reputation for toughness. Since talking was uncomfortable, he texted sportswriter George Richards the following day: “Skating around with exposed roots in your mouth is not the best.”
We agree with Yandle wholeheartedly. What we don’t agree with is waiting even one day to seek treatment after serious dental trauma. It was only on the following day that Yandle went to the dentist. And after not missing a game in over 10 years, Yandle wasn’t going to let a hiccup like losing, breaking or cracking nearly a third of his teeth interfere with his iron man streak. He was back on the ice later that day to play his 821st game.
As dentists, we don’t award points for toughing it out. If anything, we give points for saving teeth—and that means getting to the dentist as soon as possible after suffering dental trauma and following these tips:
- If a tooth is knocked loose or pushed deeper into the socket, don’t force the tooth back into position.
- If you crack a tooth, rinse your mouth but don’t wiggle the tooth or bite down on it.
- If you chip or break a tooth, save the tooth fragment and store it in milk or saliva. You can keep it against the inside of your cheek (not recommend for small children who are at greater risk of swallowing the tooth).
- If the entire tooth comes out, pick up the tooth without touching the root end. Gently rinse it off and store it in milk or saliva. You can try to push the tooth back into the socket yourself, but many people feel uneasy about doing this. The important thing is to not let the tooth dry out and to contact us immediately. Go to the hospital if you cannot get to the dental office.
Although keeping natural teeth for life is our goal, sometimes the unexpected happens. If a tooth cannot be saved after injury or if a damaged tooth must be extracted, there are excellent tooth replacement options available. With today’s advanced dental implant technology, it is possible to have replacement teeth that are indistinguishable from your natural teeth—in terms of both look and function.
And always wear a mouthguard when playing contact sports! A custom mouthguard absorbs some of the forces of impact to help protect you against severe dental injury.

What you eat (and how often you eat it) is a major factor in the ongoing battle to prevent tooth decay. High levels of sugar or similar carbohydrates in your diet could encourage the growth of bacteria that cause tooth decay. Constantly sipping on acidic beverages like sodas or sports drinks can lead to enamel erosion.
You may be well aware of the kinds of foods that contribute to tooth decay. But did you know some foods can actually protect us from this damaging disease? Here are 4 kinds of foods believed to inhibit tooth decay.
Cheese. This food formed from milk is rich in calcium and has a stimulating effect on saliva. By eating a little cheese after a sugary snack, the increase in saliva can help neutralize the acid produced by the bacteria feeding on the sugar; the added calcium will also strengthen tooth enamel.
Fibrous plant foods. Beans, peanuts and leafy vegetables are rich in fiber and many require vigorous chewing. This in turn stimulates saliva flow, which as previously noted helps to neutralize high levels of acid.
Black and green teas. Beverages brewed from these plants are rich in polyphenols and flavonoids, providing an antioxidant effect on cells. Black tea also contains fluoride, which helps strengthen tooth enamel.
Chocolate. There’s some evidence that cocoa (from which chocolate is derived) may have some properties that inhibit tooth decay. But there is a catch — this evidence is based on unrefined cocoa, without the addition of any sugar. The high levels of sugar in processed chocolate negate this effect. Sorry chocolate lovers!
Of course, any of these and similar foods (like cow’s milk) should be considered complements to a comprehensive prevention approach that includes daily oral hygiene, limits on sugar and acidic food consumption and regular dental cleanings and checkups.
