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!

Since boxers first began using them a century ago, athletic mouthguards are now standard safety equipment for most contact sports. Without them, dental injuries would skyrocket.
But a recent study in the peer-reviewed journal, General Dentistry, indicates there’s another important reason to wear a mouthguard for contact sports or exercise: you may be able to significantly reduce your risk for a mild traumatic brain injury (MTBI), better known as a concussion. It’s believed the mouthguard absorbs some of the force generated during contact, resulting in less pressure to the brain. That reduction is even more significant if your mouth-guard has been custom-made by a dentist.
That last finding is important, because not all mouthguards on the market are equal. There are three basic categories of mouthguards — stock, “boil and bite,” and custom. Stock mouthguards come in limited sizes; they’re relatively inexpensive, but they provide the least level of protection. “Boil and bite” can be customized after purchase to the wearer’s bite, but they don’t always provide complete coverage of back teeth. Custom mouthguards are designed and fashioned by a dentist; they’re relatively expensive (running in the hundreds of dollars), but there’s ample evidence they provide the highest level of protection from mouth injuries.
The General Dentistry study also corroborates custom mouthguards’ effectiveness in preventing concussions. The study followed approximately 400 football players from six different high school teams. While all the players wore the same type of helmet, half of them wore custom-made mouthguards and the other half wore stock guards. 8.3% of the athletes wearing stock guards experienced a concussion injury; by contrast only 3.6% of those with custom guards sustained an injury — greater than half fewer occurrences.
The study also highlights the need not to rely solely on helmets or other protective headgear for concussion prevention. It’s important to include mouthguards along with other athletic protective gear to lower injury risk as much as possible.
So when considering how you can provide the optimum injury protection for you or your child, be sure to include an athletic mouthguard, preferably one that’s custom-made. We’ll be happy to advise you further on what you need to know to prevent traumatic dental injuries, as well as concussions.

A child's toothache is no fun for either the child or the parent. But if you're faced with this situation, don't panic — unless they have a fever or you notice facial swelling, it's unlikely an emergency.
Â Instead, take the following steps:
Find out where it hurts and for how long. Tooth pain can stem from a lot of causes, including decay or a localized area of infection called an abscess. See if your child can tell you if it's coming from one particular tooth or from a general area. Although children can't always judge how long they've hurt, try to get a general idea so you'll know if you need to call us sooner rather than later.
Look for problem signs in the mouth. As you look where they say it hurts, see if you can see brown spots or cavities on any teeth — this would indicate tooth decay. Look also at the gums or inner areas of the mouth for sores or swelling. Unless they've had an injury, this could indicate an abscess.
Try to dislodge any food shards between teeth. It's also possible the pain is coming from a piece of hard food like a popcorn kernel wedged between their teeth. Help them gently floss between the teeth to see if you can dislodge any.
Try to ease the pain. Although you may not need to see us immediately, your child's mouth still aches. You can help relieve it temporarily with a child's dose of ibuprofen or acetaminophen. You can also apply an ice pack to the outside cheek for swelling, but don't apply the ice directly to the skin, which can burn it. And don't rub aspirin or other pain relievers on the gums — they're acidic and can irritate soft tissue.
See us for a full examination. It's wise to have any tooth pain checked — the question is often how soon. You should see us the same day or first thing in the morning if the pain has persisted for more than a day or night, pain relievers haven't eased the pain or they have fever or facial swelling. If the pain is short-lived you can usually wait until the next day — but do get it checked out.
