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.
Dental implants are widely considered the most durable tooth replacement option, thanks in part to how they attach to the jaw. But durable doesn't mean indestructible — you must take care of them.
Implants have a unique relationship to the jawbone compared to other restorations. We imbed a slender titanium post into the bone as a substitute for a natural tooth root. Because bone has a special affinity with the metal, it grows to and adheres to the implant to create a secure anchor. This unique attachment gives implants quite an advantage over other restorations.
It isn't superior, however, to the natural attachment of real teeth, especially in one respect: it can't match a natural attachment's infection-fighting ability. A connective tissue attachment made up of collagen fibers are attached to the tooth root protecting the underlying bone. An elastic gum tissue called the periodontal ligament lies between the tooth root and the bone and attaches to both with tiny collagen fibers. These attachments create a network of blood vessels that supply nutrients and infection-fighting agents to the bone and surrounding gum tissue.
Implants don't have this connective tissue or ligament attachment or its benefits. Of course, the implants are made of inorganic material that can't be damaged by bacterial infection. However, the gums and bone that surround them are: and because these natural tissues don't have these same biologic barriers to infection and perhaps access to the same degree of antibodies as those around natural teeth, an infection known as peri-implantitis specific to implants can develop and progress.
It's therefore just as important for you to continue brushing and flossing to remove bacterial plaque that causes infection to protect the gums and bone around your implants. You should also keep up regular office cleanings and checkups. In fact, we take special care with implants when cleaning them by using instruments that won't scratch their highly polished surfaces. Such a scratch, even a microscopic one, could attract and harbor bacteria.
There's no doubt dental implants are an excellent long-term solution for restoring your smile and mouth function. You can help extend that longevity by caring for them just as if they're your natural teeth.

Teeth are naturally strong and durable — if we can prevent or control dental disease like tooth decay or gum disease, they can last a lifetime. Still, teeth do wear gradually as we age, a fact we must factor into our dental care as we grow older.
Sometimes, though, the wear rate can accelerate and lead to problems much earlier — even tooth loss. There are generally four ways this abnormal wear can occur.
Tooth to tooth contact. Attrition usually results from habitual teeth grinding or clenching that are well beyond normal tooth contact. Also known as bruxism, these habits may occur unconsciously, often while you sleep. Treatments for bruxism include an occlusal guard worn to prevent tooth to tooth contact, orthodontic treatment, medication, biofeedback or psychological counseling to improve stress coping skills.
Teeth and hard material contact. Bruxism causes abrasion when our teeth regularly bite on hard materials such as pencils, nails, or bobby pins. The constant contact with these and other abrasive surfaces will cause the enamel to erode. Again, learning to cope with stress and breaking the bruxism habit will help preserve the remaining enamel.
Chronic acid. A high level of acid from foods we eat or drink can erode tooth enamel. Saliva naturally neutralizes this acid and restores the mouth to a neutral pH, usually within thirty minutes to an hour after eating. But if you’re constantly snacking on acidic foods and beverages, saliva’s buffering ability can’t keep up. To avoid this situation, refrain from constant snacking and limit acidic beverages like sodas or sports drinks to mealtimes. Extreme cases of gastric reflux disease may also disrupt your mouth’s pH — seek treatment from your medical doctor if you’re having related symptoms.
Enamel loss at the gumline. Also known as abfraction, this enamel loss is often caused by receding gums that expose more of the tooth below the enamel, which can lead to its erosion. Preventing and treating gum disease (the leading cause of receding gums) and proper oral hygiene will lower your risks of receding gums and protect tooth enamel.

Pregnancy is an exciting time in a woman’s life — but it can also generate a lot of questions about both the mother’s and the baby’s health. The realm of dental care is no exception.
Here are a few of the questions we frequently hear from expectant mothers, along with our answers.
Does the baby’s tooth calcium come from my teeth?
This question is frequently asked by mothers who may have had dental issues and are worried they’ll pass on these problems to their baby. Simply put, no — a baby developing in the womb derives minerals like calcium for their teeth and bones from the mother’s diet, not her teeth. What an expectant mother can do is be sure to eat a healthy, balanced diet rich in nutrients and minerals like calcium.
Am I at heightened risk for dental disease during pregnancy?
Pregnancy does cause significant increases in your body’s hormones, particularly estrogen. This can cause changes in the gum tissue’s blood vessels that may make you more susceptible to periodontal (gum) disease (commonly called “pregnancy gingivitis”). It’s also possible later in pregnancy to develop non-cancerous overgrowths of gum tissues called “pregnancy tumors.” The heightened risk for gum disease during pregnancy calls for increased vigilance in monitoring gum health.
What should I do to take care of my teeth?
It’s important to brush your teeth thoroughly twice a day with ADA-approved fluoridated toothpaste to remove plaque, a thin layer of bacteria and food remnants that adhere to teeth. You should also floss daily and consider using an anti-plaque/anti-gingivitis mouthrinse. And, of course, you should see us for regular office cleanings and checkups, or if you notice swollen, tender or bleeding gums, or other abnormalities.
Should I take prenatal fluoride supplements?
This sounds appealing as a way to give your baby a head start on strong tooth development. Studies on its effectiveness, however, remain slim and somewhat inconclusive — we simply don’t have enough data to make a recommendation. What does have a solid research record is the application of fluoride to teeth in young children just after they appear in the mouth — studies involving over a thousand teeth have shown 99% cavity-free results using topical fluoride applications with sealants.

Sports drinks have been widely touted as an ideal way to replenish carbohydrates, electrolytes and, of course, fluids after a strenuous event or workout. But the mixtures of many popular brands often contain acid and added sugar, similar to other types of soft drinks. This can create an acidic environment in the mouth that can be damaging to tooth enamel.
Of course, the best way to replenish fluids after most strenuous activities is nature’s hydrator, water. If, however, you or a family member does drink the occasional sports beverage, you can help reduce the acid impact and help protect tooth enamel by following these 3 tips.
Avoid sipping a sports drink over long periods. Sipping on a drink constantly for hours interferes with saliva, the bodily fluid responsible for neutralizing mouth acid. But because the process can take thirty minutes to an hour to bring the mouth to a normal pH, saliva may not be able to complete neutralization because of the constant presence of acid caused by sipping. It’s best then to limit sports drinks to set periods or preferably during mealtimes.
Rinse your mouth out with water after drinking.Â Enamel damage occurs after extended periods of exposure to acid. Rinsing your mouth out immediately after consuming a sports drink will wash away a good amount of any remaining acid and help normalize your mouth’s pH level. And since water has a neutral pH, it won’t add to the acid levels.
Wait an hour to brush after eating. As mentioned before, saliva takes time to neutralize mouth acid. Even in that short period of time, though, acid can soften some of the mineral content in enamel. If you brush during this “soft” period, you may inadvertently brush away some of the minerals. By waiting an hour, you give saliva time not only to neutralize acid but also restore mineral strength to the enamel.
