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!

EvenCelebritiesLikeJenniferLawrenceArentImmuneFromBadBreath

Exchanging passionate kisses with big-screen star Jennifer Lawrence might sound like a dream come true. But according to Liam Hemsworth, her Hunger Games co-star, it could also be a nightmare… because J.Law’s breath wasn’t always fresh. “Anytime I had to kiss Jennifer was pretty uncomfortable,” Hemsworth said on The Tonight Show.

Lawrence said the problem resulted from her inadvertently consuming tuna or garlic before the lip-locking scenes; fortunately, the two stars were able to share a laugh about it later. But for many people, bad breath is no joke. It can lead to embarrassment and social difficulties — and it occasionally signifies a more serious problem. So what causes bad breath, and what can you do about it?

In 9 out of 10 cases, bad breath originates in the mouth. (In rare situations, it results from a medical issue in another part of the body, such as liver disease or a lung infection.) The foul odors associated with bad breath can be temporarily masked with mouthwash or breath mints — but in order to really control it, we need to find out exactly what’s causing the problem, and address its source.

As Lawrence and Hemsworth found out, some foods and beverages can indeed cause a malodorous mouth. Onions, garlic, alcohol and coffee are deservedly blamed for this. Tobacco products are also big contributors to bad breath — which is one more reason to quit. But fasting isn’t the answer either: stop eating for long enough and another set of foul-smelling substances will be released. Your best bet is to stay well hydrated and snack on crisp, fresh foods like celery, apples or parsley.

And speaking of hydration (or the lack of it): Mouth dryness and reduced salivary flow during the nighttime hours is what causes “morning breath.” Certain health issues and some medications can also cause “dry mouth,” or xerostomia. Drinking plenty of water can encourage the production of healthy saliva — but if that’s not enough, tell us about it: We may recommend switching medications (if possible), chewing xylitol gum or using a saliva substitute.

Finally, maintaining excellent oral hygiene is a great way to avoid bad breath. The goal of oral hygiene is to control the harmful bacteria that live in your mouth. These microorganisms can cause gum disease, tooth decay, and bad breath — so keeping them in check is good for your overall oral health. Remember to brush twice and floss once daily, stay away from sugary foods and beverages, and visit the dental office regularly for checkups and professional cleanings.

So did J.Law apologize for the malodorous makeout session? Not exactly. “[For] Bradley Cooper, Christian Bale, yeah, I’ll brush my teeth,” she laughed.

Hemsworth jokingly agreed: “If I was kissing Christian Bale I probably would have brushed my teeth too. With you, it’s like, ‘Eh. Whatever.’”

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.

ActorDavidRamseySaysDontForgettoFloss

Can you have healthy teeth and still have gum disease? Absolutely! And if you don’t believe us, just ask actor David Ramsey. The cast member of TV hits such as Dexter and Arrow said in a recent interview that up to the present day, he has never had a single cavity. Yet at a routine dental visit during his college years, Ramsey’s dentist pointed out how easily his gums bled during the exam. This was an early sign of periodontal (gum) disease, the dentist told him.

“I learned that just because you don’t have cavities, doesn’t mean you don’t have periodontal disease,” Ramsey said.

Apparently, Ramsey had always been very conscientious about brushing his teeth but he never flossed them.

“This isn’t just some strange phenomenon that exists just in my house — a lot of people who brush don’t really floss,” he noted.

Unfortunately, that’s true — and we’d certainly like to change it. So why is flossing so important?

Oral diseases such as tooth decay and periodontal disease often start when dental plaque, a bacteria-laden film that collects on teeth, is allowed to build up. These sticky deposits can harden into a substance called tartar or calculus, which is irritating to the gums and must be removed during a professional teeth cleaning.

Brushing teeth is one way to remove soft plaque, but it is not effective at reaching bacteria or food debris between teeth. That’s where flossing comes in. Floss can fit into spaces that your toothbrush never reaches. In fact, if you don’t floss, you’re leaving about a third to half of your tooth surfaces unclean — and, as David Ramsey found out, that’s a path to periodontal disease.

Since then, however, Ramsey has become a meticulous flosser, and he proudly notes that the long-ago dental appointment “was the last we heard of any type of gum disease.”

Let that be the same for you! Just remember to brush and floss, eat a good diet low in sugar, and come in to the dental office for regular professional cleanings.

If you would like more information on flossing or periodontal disease, please contact us today to schedule an appointment for a consultation. You can also learn more by reading the Dear Doctor magazine article “Understanding Gum (Periodontal) Disease.”

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.
