KidsCatsandCaninesDentalDevelopmentThroughtheAges

What do young saber tooth tigers, which have been extinct about 10,000 years, have in common with human kids today? At first glance, not a lot. Smilodon fatalis, the big cat of North America, reached adulthood at around age three and weighed up to 600 pounds. But these ice-age mammals are probably best known for their dagger-like canine teeth, which (as shown by many well-preserved skeletons) grew up to 7 inches long. And that’s where the comparison between kids and kitties gets interesting.

The toothy felines had primary (baby) teeth and adult teeth, which developed in a similar way to human dentition. The primary teeth came in first, persisted during the young cat’s development, and shared space in the mouth as the adult teeth were erupting (growing in) — with one big difference. According to a recent study reported in the academic journal PLOS ONE, those colossal canines grew at an astonishing rate: up to 6 millimeters per month! By comparison, human primary teeth emerge from the gums at around 0.7mm per month, while permanent teeth may grow up to 2mm per month.

It’s understandable why those tiger teeth developed so rapidly: Life in the Ice Age was hard, and predators needed every advantage just to stay alive. But while human baby teeth take longer to develop (and to go away), they, too, are vitally important. For one thing, the primary teeth let kids bite, chew, speak (and smile) properly, until they are replaced by adult teeth — a process that isn’t usually finished until a child reaches the age of 12-13. So those “baby” teeth allow kids to have good nutrition — and positive social interactions — for a significant part of childhood!

There’s another important thing primary teeth do before they’re gone: They help ensure that the succeeding teeth come in properly, by holding a space in the jaw that will later be filled by a permanent tooth. If baby teeth are lost prematurely, those spaces can close up, resulting in permanent teeth that emerge too close together, or in the wrong places. This condition, called malocclusion (bad bite), can usually be corrected by orthodontics. But it’s better to avoid the inconvenience (and cost) of braces, if possible.

That’s why it’s so important to take care of your child’s baby teeth. Even though they won’t be around forever, they have a vital role to play right now. So be sure proper attention is paid to your child’s oral hygiene: That means avoiding sugar, and remembering to brush and floss every day. And be sure to come in regularly for routine exams, cleanings, and needed care. It’s the best way to keep those little teeth from “going extinct” too soon!

TheMajorBenefitsofEarlyChildhoodDentalVisits

For a lifetime of healthy teeth and gums, it takes a lifetime of personal and professional care. Starting your child’s daily hygiene with the first tooth eruption is a must; but you should also consider beginning regular dental visits in their early years, around or before their first birthday.

There’s evidence that early dental visits hold a number of benefits that could lead to reduced oral care costs over their lifetime.

Familiarity with professional dental care. Children need to feel comfortable and safe in their surroundings, especially new places. Beginning dental visits early improves the chances your child will view the dentist’s office as a regular part of their life. It’s especially helpful if the dental professional has training and experience with young children to put them at ease.

Early monitoring for dental disease or other problems. A young child’s teeth are highly susceptible to tooth decay. Dental visits that begin early in a child’s life increase our chances of detecting any developing dental problems early. In addition to treating decayed teeth, your child may also need preventative actions like sealants or additional fluoride applications to protect teeth if they are at a higher risk for disease. As the child develops, we may also be able to catch early bite problems: with interventional treatment, it may be possible to reduce future orthodontic costs.

Parental help and support. As we discuss your child’s dental care with you, we’ll be able to provide essential information and training for how to care for their teeth and gums at home. We’ll also be able to ease any common concerns you may have, such as thumb sucking or other oral habits, as well as give you sound advice and techniques for dealing with these problems.

As with other areas of childhood development, starting off on the right foot with oral care can make all the difference to their future dental health. The sooner you begin regular dental visits with your toddler, the better their chances for a lifetime of healthy teeth and gums.

SalivaPerformsManyFunctionsforBothOralandGeneralHealth

While oral hygiene, a nutritious diet and regular dental visits are all crucial to long-term oral health, these efforts complement what your body already does to keep your mouth healthy. One of the major players in this function is saliva.

Produced by hundreds of glands located throughout the mouth, saliva does much more than help you swallow and wash away food. As you chew, an enzyme in saliva known as amylase breaks down starches in your food to make it easier to digest in the stomach. Saliva also contains antibodies, similar to what’s in tears, which can fight bacteria and other disease-causing organisms.

Perhaps its most important function, though, is its ability to protect and maintain healthy tooth enamel. The strongest substance in the body, enamel nevertheless has one primary enemy — the acid found in certain foods or as a byproduct of bacteria feeding on sugar and other carbohydrates.

When the ideally neutral pH level of the mouth becomes too acidic (nearly every time you eat), minerals in the enamel begin to soften and dissolve. The increased saliva flow when we eat floods the mouth with buffering agents that neutralize the acid and restore the mouth’s normal pH level. Not only does saliva stop demineralization, but it also restores a good bit of the enamel’s mineral content.

In recent years, a new role for saliva has begun to emerge as a means to diagnose disease. Like blood, urine and other bodily fluids, saliva contains molecules that serve as biological markers for disease. Given the right equipment, saliva has the potential to indicate early signs of cancer (including oral), diabetes and other systemic conditions. As the means to examine saliva for these markers increases it promises to be easier and less expensive to collect and sample than blood, while reducing the chances of transmitting bloodborne diseases to healthcare workers.

It’s a lot to consider with this fluid that you hardly notice, except when it isn’t there. Saliva is proof that our efforts at keeping our mouths healthy cooperate and depend on our bodies’ amazing systems.

If you would like more information on saliva and other ways your body maintains a healthy mouth, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Saliva.”

GlutenSensitivitycanLeadtoDentalProblems

There’s been a growing awareness about the effects of gluten, a protein found in grains like wheat, rye and sometimes oats, on certain people. An estimated 1 in 133 Americans have Celiac Disease (CD), a gluten-related disorder that causes the body’s immune system to work against itself. And if you have CD, you could eventually face dental problems like enamel pitting and erosion.

When a person with CD consumes gluten, their immune system mistakenly identifies the protein as malicious and attacks it. The attack occurs in the membranes that line the digestive system, which in the process destroys cilia, tiny hair-like structures that aid in food absorption. This disrupts the body’s normal absorption of nutrients, which can lead to a number of systemic conditions including intestinal cancer.

Because of the lack of nutrients, your teeth’s enamel may develop defects. You may begin to see dull spots or pitting, or chalky grooves in its normally shiny surface: this is a sign you’ve lost surface enamel crystals (decalcification). You may also be more susceptible to outbreaks of aphthous ulcers (canker sores).

Because symptoms can be misdiagnosed or go unnoticed, it may be years before you know you have CD. You can, however, get a definitive diagnosis through a blood test for gluten antibodies, which is then confirmed with a biopsy of a tissue specimen from the intestine.

While there’s ongoing research for CD-related medication, there’s currently only one recognized treatment for it — remove gluten from your diet. This is much harder than it sounds, and requires knowing what you can and can’t eat, along with strict monitoring of food package labeling. Thankfully, the world is becoming better educated in this respect as more food manufacturers are clearly labeling products containing gluten and restaurants are providing gluten-free menu options.

Once you have dietary controls in place, your dental issues can be treated as any other person, with one exception: none of the products used in treatment like polishing paste or fluoride gels should contain gluten, and must be verified before using.

CD is a serious condition that could even become life-threatening. Knowing you or someone in your family has it will help you protect both your overall health and your teeth.

If you would like more information on the gluten’s effect on dental health, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Gluten & Dental Problems.”
