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.

Calling someone "long in the tooth" is an unflattering way of saying they're getting old. The phrase refers to the effects of gum recession, in which the gums pull away from the teeth and cause them to appear longer. The problem, which makes the teeth vulnerable to disease as well as look unattractive, is a common problem for older people.
The most common cause for gum recession is periodontal (gum) disease. Bacteria and food particles, which make up dental plaque, trigger an infection. The deposits of plaque and calculus (hardened plaque) continue to fuel the infection as it continues to weaken gum tissue attachments.
As a result, the gums begin to lose their attachment to the teeth and pull away, exposing the root areas normally covered by the gums. Unlike the enamel-protected crowns (the parts of teeth you can see), the root is covered by a thin layer of material called cementum.
Although cementum offers less protection than enamel, this normally isn't a problem because the gums also act as a barrier against bacteria and other harsh aspects of the mouth environment. But without gum coverage, the root area becomes vulnerable to disease and is more prone to painful sensitivity.
Because gum disease is the main culprit, you can reduce your chances of gum recession by keeping your teeth clean of plaque through brushing and flossing, and regularly undergoing professional cleanings. If gum disease does occur, it's important to seek treatment as soon as possible: The earlier it's treated the more likely that any recessed gum tissues can regenerate.
If the recession is extensive, however, you may need clinical intervention to assist with its regrowth. This can be done by grafting tissue at the site that then serves as scaffold for new tissue to grow upon. Though effective, these microsurgical techniques are quite complex and involved.
So, if you suspect you have gum disease or recession, see your dentist as soon as possible for a full examination. It may be possible to restore your gums and enhance your smile.

You depend on your family dentist for most of your oral care. There are some situations, though, that are best handled by a specialist. If you or a family member has a deeply decayed tooth, for example, it might be in your long-term interest to see an endodontist.
From the Greek words, endo ("within") and odont ("tooth"), endodontics focuses on dental care involving a tooth's interior layers, including the pulp, root canals and roots. While general dentists can treat many endodontic problems, an endodontist has the advanced equipment and techniques to handle more complex cases.
The majority of an endodontist's work involves teeth inwardly affected by tooth decay. The infection has moved beyond the initial cavity created in the enamel and dentin layers and advanced into the pulp and root canals. The roots and underlying bone are in danger of infection, which can endanger the tooth's survival.
The most common treatment is root canal therapy, in which all of the infected tissue is removed from the pulp and root canals. Afterward, the empty spaces are filled and the tooth is sealed and crowned to prevent future infection. General dentists can perform this treatment, primarily with teeth having a single root and less intricate root canal networks. But teeth with multiple roots are a more challenging root canal procedure.
Teeth with multiple roots may have several root canals needing treatment, many of which can be quite small. An endodontist uses a surgical microscope and other specialized equipment, as well as advanced techniques, to ensure all of these inner passageways are disinfected and filled. Additionally, an endodontist is often preferred for previously root-canaled teeth that have been re-infected or conditions that can't be addressed by a traditional root canal procedure.
While your dentist may refer you to an endodontist for a problem tooth, you don't have to wait. You can make an appointment if you think your condition warrants it. Check out the American Association of Endodontists webpage www.aae.org/find for a list of endodontists in your area.
Advanced tooth decay can put your dental health at risk. But an endodontist might be the best choice to overcome that threat and save your tooth.
