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!

Teething is an important phase in your baby's dental maturity. During the approximate two-year process, they will acquire their first set of teeth.
It can also be an unpleasant two years as each tooth sequentially breaks through the gums. The severity of teething problems differs with each child, but there are common signs: irritability, biting and gnawing, chin rash, drooling or ear rubbing among them. Although for most babies the discomfort isn't that great, the pain can occasionally be a lot for them — and their care-givers — to handle.
Although having a very unhappy infant can be nerve-jangling, there's no real cause for concern health-wise. If, however, they begin to run a fever or experience diarrhea, that could be a sign of something more serious. In those cases, you should see a doctor as soon as possible.
Otherwise, there are some things you can do to make them more comfortable during teething episodes. One thing to remember: cold items for biting or gnawing usually work wonders. So, be sure you have chilled teething rings or pacifiers (but not frozen — the extreme temperature could burn their gums). For older children, an occasional cold food like a popsicle can bring relief.
You can also try massaging the gums with your clean finger, which will help counteract the pressure of an erupting tooth. But avoid rubbing alcohol or aspirin on the gums, and you shouldn't apply numbing agents to children less than two years of age unless advised by your doctor.
If their pain persists, it's permissible to give them a mild pain reliever like the appropriate dosage for their age of baby acetaminophen or ibuprofen. Again, you should give this by mouth and avoid rubbing it on the gums.
By the time they're three, all their primary teeth should be in and teething symptoms should have largely dissipated. In the meantime, make them as comfortable as you can â?? in no time the unpleasantness of teething will pass.

You're doing all the right things helping your child avoid tooth decay: daily brushing and flossing, regular dental visits and a low-sugar diet. But although occurrences are low, they're still getting cavities.
Some children still struggle with tooth decay even with proper dental care. If this is happening to your child, your dentist may be able to give them an extra preventive boost through topical fluoride.
Fluoride has long been recognized as a proven cavity fighter. Often added in small amounts to toothpastes and drinking water, fluoride strengthens tooth enamel against acid attacks that create cavities. With topical fluoride, a dentist applies a varnish, foam or gel containing a more concentrated amount of the chemical directly to the teeth.
The effectiveness of this method in reducing tooth decay is well-founded: A number of scientific studies involving thousands of children and adolescents found an average 28% reduction in occurrences of decay among those who received the treatment compared to those who didn't.
Still, many parents have concerns about the higher fluoride concentrations in topical applications. But even at this greater amount, fluoride doesn't appear to pose any long-term health risks. The most adverse effects—vomiting, headaches or stomach pain—usually occur if a child accidentally ingests too much of the solution during treatment.
Dentists, however, go to great lengths to prevent this by using guards to isolate the solution during an application. And in the case of a foam or gel application, parents can further lower the risk of these unpleasant side effects by not allowing their child to eat or drink for at least thirty minutes after the procedure.
The evidence seems to indicate that the benefits of regular topical fluoride applications for children at high risk outweigh the possible side effects. By adding this measure to your prevention strategy, you can further protect your child from this danger to their current and future dental health.

A child with a chronic illness or condition often requires a lot of focus on care for their special needs. Other aspects of their health can often take a back seat — too often including dental care.
Proper dental care can be a challenge for special needs children if they have diminished physical, intellectual or behavioral capacities. Children with autism or attention deficit disorders may not be able or willing to perform tasks like brushing and flossing. Other conditions could make them intolerant to toothpaste in the mouth, or create an inability to keep their mouths open or to spit.
Some chronic conditions also seem predisposed to dental defects. For example, enamel hypoplasia, a lack of sufficient tooth enamel, is common with Down, Treacher-Collins or Turner Syndromes, and can greatly increase the risk of tooth decay.
But even though difficult, effective dental care isn't impossible. It begins with your dental provider.
Pediatric dentists are often excellent in this regard: they often have the training and experience to treat children with chronic conditions. Whoever you choose must be able to partner with you in caring for your child's dental needs.
Daily hygiene is also a critical factor. Your goal should be the same as with any child — to teach them to brush and floss for themselves. Depending on their condition, however, you may need to assist them for a longer term, perhaps permanently. But it is imperative — daily hygiene is their best defense against oral diseases.
You should also consider their medication and how it may impact their dental health. Antidepressants, antihistamines or drugs that assist with breathing function can cause mouth dryness. This, as well as drugs with sugar or acid compounds, can increase risk for dental disease. If they must take these types of medications, try to give them at mealtime to reduce their effect in the mouth.
Above all, pursue the same professional dental care as you would for any other child. Keep up regular dental visits beginning around their first birthday for cleanings and preventive measures like topical fluoride or sealants. By taking these measures you'll help ensure their dental health won't suffer.

Taking care of your child’s teeth is a high priority, not only for their health now but for the future too. And that means dealing with their teeth’s most common and formidable enemy, tooth decay.
Your focus, of course, should be on preventing decay through good oral hygiene practices, a healthy diet low in foods with added sugar and regular office visits for cleaning and checkups. But some children at higher risk or who’ve already encountered tooth decay may also need a little extra help in the form of dental sealants.
The most common use of sealants addresses a weakness in young teeth that disease-causing bacteria exploit. Deep grooves known as pits and fissures form within the biting surfaces of developing back teeth and in the rear of front teeth.Â It’s very difficult to reach these areas with daily brushing, so some plaque may be left behind (hence the importance of semi-annual office cleanings).
Inside the mouth, these pits and fissures are in a warm and moist environment and are a haven for bacteria that feed on plaque and produce high levels of acid as a by-product. The acid softens enamel to eventually create a hole, or a “cavity” in the tooth. Children’s young enamel is highly susceptible to this process — it hasn’t developed enough strength to resist the adverse effects of acid.
A “pit and fissure” sealant made of resin fills in the grooves in the teeth to inhibit the buildup of plaque — a kind of “mini” filling. It’s an added layer of protection that complements other prevention efforts. But applying them isn’t an automatic practice — we only recommend it for children at high risk, especially where decay is beginning or it appears the conditions are conducive for it. When needed, though, it can be quite effective in preventing decay or minimizing its effects.
The best way to know if your child could benefit from a sealant is to have them undergo a complete dental exam. From there we can advise you on whether a sealant application is an important investment in their current and future health.
