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.Â 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!
If you have questions or concerns about your child’s baby teeth, please call our office to schedule a consultation. You can read more in the Dear Doctor magazine articles “Importance of Baby Teeth” and “Early Loss of Baby Teeth.”
Your diet can play as important a role in your dental health as brushing and flossing. What you eat (particularly sugar) could increase your risk of tooth decay despite your hygiene habits. And vice-versa: a nutritious diet may help boost your preventive efforts even more.
Let’s look at two very different approaches to diet and see how your dental health is likely to fare under each.
A High Sugar/Low Fiber Diet. Modern western diets heavy with processed foods are inundated with two particular types of refined sugars. The first is sucrose, which comes mainly from either beets or sugar cane. Foods (and beverages) may also contain a refined sugar from corn known as high fructose corn syrup. Refined sugars are added for taste to thousands of products like cake, candy, soft drinks or even condiments like catsup. These “free” sugars are easily processed by bacteria into acid. Combine that with fewer fibrous vegetables in the diet and you have a recipe not only for obesity and other health issues, but tooth decay as well.
A High Fiber/Low Sugar Diet. Fruits and vegetables make up a large part of this kind of diet, while added free sugars much less so. That doesn’t make this diet sugar-free: all plant products contain simple sugars produced by photosynthesis. The difference, though, is that these sugars — glucose, fructose and sucrose (natural, not the refined versions) — are more slowly absorbed into the bloodstream during digestion because of the fiber content of fruits and vegetables. You’ll also receive other nutrients like vitamins and minerals necessary for good health. Eating this kind of diet will help decrease the risk of tooth decay.
So there you have it: eat more fresh fruits and vegetables and restrict your intake of processed foods and sweets. You may also want to fine-tune a few items to maximize decay prevention: for example, eat starches in their natural form (whole grains, beans or certain fruits) as much as possible rather than refined or in combination with added sugar (cakes, cookies, etc.). And while fresh fruits with their naturally occurring sugars aren’t a significant factor in tooth decay, dried fruits (especially with added sugar) might.

If you had chicken pox as a child, you're at higher risk for a painful viral infection later in life called shingles. Besides a painful skin rash and other symptoms that can develop, shingles could also affect your dental care.
About 90% of children contract chicken pox, a disease caused by the varicella zoster virus (VZV), which usually clears up on its own. But later in life, usually after age 50, about a quarter to a third of chicken pox patients will develop shingles.
The onset of shingles usually produces an itching or burning sensation on the skin that's either numb or overly sensitive to the touch. A red rash may ensue with crusty lesions, accompanied sometimes by pain, fever and fatigue. The rash often forms a belt-like or striped pattern along one side of the face or body.
For most patients this painful rash is the extent of their symptoms. But women who are pregnant, patients undergoing cancer treatment or people with compromised immune systems are at risk for more serious complications if they contract the disease. It's important for these at-risk patients to obtain a vaccination, as well as avoid contact with anyone with shingles.
Which brings us to your dental care: in its early stages shingles can be contagious, the virus passing to others through skin contact or by airborne respiratory secretions. That's why it's important if you're currently experiencing a shingles episode that you let us know before undergoing any kind of dental work.Â Even a routine teeth cleaning with an ultrasonic device could disrupt the virus and increase the chances of it spreading to someone else. We may need to postpone dental work until the virus is under control.
Antiviral drugs like acyclovir or famciclovir are highly effective in bringing the disease under control, especially if treatment starts within three days of the onset of symptoms. And don't forget the shingles vaccination: the U.S. Center for Disease Control recommends it for anyone 60 or older regardless of a past history with chicken pox.
See your physician as soon as possible if you begin to notice symptoms. Don't let shingles interfere with your life — or your dental care.
In the last half century, fluoride has become an effective weapon against tooth decay. The naturally occurring mineral helps strengthen enamel, the teeth's hard, protective cover.
Although it's safe for consumption overall, too much during early tooth development can lead to fluorosis, a brownish, mottled staining in enamel. To avoid it, a child's daily consumption of fluoride should optimally be kept at around 0.05-0.07 milligrams per kilogram of body weight, or an amount equal to one-tenth of a grain of salt per two pounds of weight.
The two main therapeutic fluoride sources have limits to help maintain this balance: utilities that fluoridate drinking water are required to add no more than 4 parts fluoride per million (ppm) of water; toothpaste manufacturers likewise only add a small amount of fluoride compared to clinical gels and pastes dentists apply to teeth for added decay protection.
But drinking water and toothpaste aren't the only sources of fluoride your child may encounter. Even if you have a non-fluoridated water supply, you should still keep a close watch on the following items that could contain fluoride, and discuss with us if you should take any action in regard to them.
Infant formula. The powdered form especially if mixed with fluoridated water can result in fluoride concentrations 100 to 200 times higher than breast or cow's milk. If there's a concern, use fluoride-free distilled or bottled spring water to mix formula.
Beverages. Many manufacturers use fluoridated water preparing a number of packaged beverages including sodas (two-thirds of those manufactured exceed .6 ppm), soft drinks and reconstituted fruit juices. You may need to limit your family's consumption of these kinds of beverages.
Certain foods. Processed foods like cereals, soups or containing fish or mechanically separated chicken can have high fluoride concentrations, especially if fluoridated water was used in their processing. When combined with other fluoride sources, their consumption could put children at higher risk for fluorosis.
Toothpaste. Although mentioned previously as a moderate fluoride source, you should still pay attention to how much your child uses. It doesn't take much: in fact, a full brush of toothpaste is too much, even for an adult. For an infant, you only need a smear on the end of the brush; as they grow older you can increase it but to no more than a pea-sized amount.
