Mention “bacteria” and people begin looking for the germicide. The truth is, though, only a few strains cause disease — the rest are benign or even play a beneficial role.
This may shock you, but your body both inside and out is home to around 100 trillion single-celled organisms, exceeding the number of your native cells by 10 to 1. You won't notice them, though: bacteria are so small they only make up 1 to 3% of your total body mass. And each of us has a unique “microbiome” of micro-organisms: they influence a variety of processes like digestion and metabolism, and some even “teach” our immune systems to distinguish between helpful and harmful bacteria.
Of the 10,000 or more species of bacteria that inhabit the body, perhaps the most studied and understood are in the mouth. We even have a database that catalogs the gene sequences of oral bacteria. And what we've learned has enlarged our understanding of dental disease and how to prevent or treat it.
This new knowledge, for example, confirms that many of our modern lifestyle habits adversely affect oral health. For example, researchers have found higher concentrations of Streptococcus mutans, the bacteria most responsible for tooth decay, in current samples of biofilm than in those from preindustrial eras. The culprit seems to be the modern diet rich with carbohydrates like sugar that bacteria eat. Cigarette smoking can also make the mouth friendlier to disease-causing bacteria.
On the bright side, our growing knowledge of oral bacteria is helping us devise better prevention and treatment strategies. One example is the use of antibiotics to reduce the populations of disease-causing oral bacteria.
The broad, traditional approach kills not only malevolent bacteria, but beneficial strains as well. The approach may also be helping bad bacteria become resistant to common antibiotics. A newer approach targets specific bacteria with custom-designed antibiotics that won't kill other bacteria. There's also increased focus on ways to re-balance a person's normal microbiome if it's become skewed.
As we come to understand bacteria better — both good and bad species — these and other dental care efforts will benefit. With our increasing knowledge of these microorganisms that surround us the future looks bright for better oral health.

The National Safety Council has designated June as National Safety Month. A key component of staying safe is being prepared for emergencies, and this includes dental emergencies. Would you know what to do if you suffered any of the following dental mishaps?
Chipped tooth: One common dental injury is a chipped tooth. If this happens to you, save the missing chip if possible because we may be able to bond it back onto the tooth—but don’t be tempted to glue the chip back on by yourself! However, even without the missing chip, the tooth can most often be repaired with bonding material.
Cracked tooth: If you crack a tooth, rinse your mouth with warm water. If it is bleeding, hold a clean washcloth or gauze to the area until the bleeding stops, but don’t wiggle the tooth around or bite down hard. Keep in mind that the sooner your tooth is repaired, the better. Depending on how bad the crack is, if the tooth can be treated, it will most likely continue to function pain-free for years to come.
Displaced (“luxated”) tooth: If an injury causes your tooth to become loose, shoves it sideways or pushes it into or out of its socket, don’t try to force the tooth back into position on your own. Instead, call the dental office right away and leave it to us to bring the tooth back into its proper place and determine the extent of the injury.
Knocked out tooth: If a permanent tooth is knocked out of your mouth, pick it up without touching the root and rinse it off with cold water, but do not scrub. For the best chance of saving the tooth, place it firmly back in its socket within five minutes and hold it in position for a few minutes. If this is not possible, keep the tooth between your cheek and gum or in a glass of cold milk so that it doesn’t dry out. Call the dental office immediately.
If a baby tooth is knocked out, there is no need to place it back in the socket since baby teeth are not reattached. However, it is still important to have us examine the injury.
Being prepared for dental emergencies can help save a tooth as well as avoid more costly dental treatment down the road. But no matter what type of dental injury you have, it is important to come in for a consultation as the injury may extend beyond the part of the tooth that is visible. With today’s materials and technology, there’s a very good chance your smile can look as good as before—and often even better!
If you have questions about dental injuries, please contact our office or schedule a consultation. To learn more, read the Dear Doctor magazine articles “Trauma and Nerve Damage to Teeth” and “Artistic Repair of Front Teeth with Composite Resin.”
While it's possible for a teenager to lose a tooth from decay, it's more common they'll lose one from an accidental knockout. If that happens to your teenager, there are some things you should know to achieve a good outcome.
Our top concern is to preserve the underlying bone following tooth loss. Like other tissues, bone has a life cycle: older cells dissolve and are absorbed by the body (resorption), then replaced by new cells. The biting pressure generated when we chew helps stimulate this growth. But bone around a missing tooth lacks this stimulation and may not keep up with resorption at a healthy rate.
This can cause a person to lose some of the bone around an empty tooth socket. To counteract this, we may place a bone graft at the site. Made of bone minerals, usually from a donor, the graft serves as a scaffold for new bone growth. By preventing significant bone loss we can better ensure success with a future restoration.
Because of its lifelikeness, functionality and durability, dental implants are considered the best of the restoration options that can be considered to replace a missing tooth. But placing an implant during the teen years is problematic because the jaws are still growing. If we place an implant prematurely it will appear to be out of alignment when the jaw fully matures. Better to wait until the jaw finishes development in early adulthood.
In the meantime, there are a couple of temporary options that work well for teens: a removable partial denture (RFP) or a fixed modified bridge. The latter is similar to bridges made for adults, but uses tabs of dental material that bond a prosthetic (false) tooth to the adjacent natural teeth to hold it in place. This alleviates the need to permanently alter the adjacent natural teeth and buy time so that the implant can be placed after growth and development has finished.
And no need to worry about postponing orthodontic treatment in the event of a tooth loss. In most cases we can go ahead with treatment, and may even be able to incorporate a prosthetic tooth into the braces or clear aligners.
It's always unfortunate to lose a tooth, especially from a sudden accident. The good news, though, is that with proper care and attention we can restore your teenager's smile.
