When you're first startled awake in the middle of the night by a loud, gritting sound emanating from your child's room, you may have two questions: how can such a loud racket not be harmful to their teeth? And, how can they sleep through it?
While it sounds earth-shattering, teeth grinding (medically known as bruxism) is a common habit among children. It involves an involuntary grinding, clenching or rubbing of the teeth together, either during the day or during night sleep.
While certain medications or conditions could be factors, it's believed most teeth grinding arises from the immaturity of the part of the neuromuscular system that controls chewing. It's believed to trigger a night episode as the child moves from deeper to lighter stages of sleep toward waking. Older children and adults typically handle these sudden shifts without incident, but a young child's under-developed chewing response may react with grinding.
If a child's teeth are normal and healthy, teeth-grinding typically won't create any lasting damage. But because grinding does generate pressures greater than the teeth normally encounter, it can be harmful to decayed teeth or those with enamel erosion due to high acid from consumption of sports and soda drinks. And it's also a cause for concern if the habit continues into later childhood or adolescence.
To avoid these problems, it's best to keep your child's teeth as healthy as possible by practicing daily brushing and flossing, and regularly seeing a dentist for cleanings, treatments and preventive measures like topical fluoride or sealants. And be sure to limit sugar and acidic foods and drinks in their diet to protect against decay and erosion.
You can also take steps to minimize teeth grinding and its effects. Consult with your physician about any medications they're taking that might contribute to the habit. If there are psychological issues at play, seek therapy to help your child better manage their stress. Your dentist can also fashion a custom night guard worn while they sleep that will prevent their teeth from making solid contact during grinding episodes.
Most importantly, let your dentist know if your child grinds their teeth. Keeping an eye on this potentially harmful habit will help lead to appropriate actions when the time comes.

When they’re introducing a new movie, actors often take a moment to pay tribute to the people who helped make it happen — like, you know, their dentists. At least that’s what Charlize Theron did at the premiere of her new spy thriller, Atomic Blonde.
"I just want to take a quick moment to thank my dentists," she told a Los Angeles audience as they waited for the film to roll. "I don’t even know if they’re here, but I just want to say thank you."
Why did the starring actress/producer give a shout-out to her dental team? It seems she trained and fought so hard in the action sequences that she actually cracked two teeth!
“I had severe tooth pain, which I never had in my entire life,” Theron told an interviewer from Variety. At first, she thought it was a cavity — but later, she found out it was more serious: One tooth needed a root canal, and the other had to be extracted and replaced with a dental implant — but first, a bone grafting procedure was needed. “I had to put a donor bone in [the jaw] to heal,” she noted, “and then I had another surgery to put a metal screw in there.”
Although it might sound like the kind of treatment only an action hero would need, bone grafting is now a routine part of many dental implant procedures. The reason is that without a sufficient volume of good-quality bone, implant placement is difficult or impossible. That’s because the screw-like implant must be firmly joined with the jawbone, so it can support the replacement tooth.
Fortunately, dentists have a way to help your body build new bone: A relatively small amount of bone material can be placed in the missing tooth’s socket in a procedure called bone grafting. This may come from your own body or, more likely, it may be processed bone material from a laboratory. The donor material can be from a human, animal or synthetic source, but because of stringent processing techniques, the material is safe for human use. Once it is put in place your body takes over, using the grafted material as a scaffold on which to build new bone cells. If jawbone volume is insufficient for implants, it can often be restored to a viable point in a few months.
Better yet, when grafting material is placed in the tooth socket immediately after extraction, it can keep most of the bone loss from occurring in the first place, enabling an implant to be placed as soon as possible — even before the end of a movie’s shooting schedule.
Will Atomic Blonde prove to be an action-movie classic? Only time will tell. But one thing’s for sure: When Charlize Theron walks down the red carpet, she won’t have to worry about a gap in her smile.

At any given time some 4 million teens and pre-teens are wearing braces or other orthodontic appliances to correct a malocclusion (poor bite). While most cases are straightforward, some have difficulties that increase treatment time and cost.
But what if you could reduce some of these difficulties before they fully develop? We often can through interceptive orthodontics.
This growing concept involves early orthodontic treatment around 6 to 10 years of age with the goal of guiding the development of a child’s jaws and other mouth structures in the right direction. These early years are often the only time of life when many of these treatments will work.
For example, widening the roof of the mouth (the palate) in an abnormally narrow upper jaw takes advantage of a gap in the bone in the center of the palate that doesn’t fuse until later in adolescence. A device called a palatal expander exerts outward pressure on the back teeth to influence the jawbone to grow out. New bone fills in the gap to permanently expand the jaw.
In cases with a developing overbite (the upper front teeth extending too far over the lower teeth when closed), we can install a hinged device called a Herbst appliance to the jaws in the back of the mouth. The hinge mechanism coaxes the lower jaw to develop further forward, which may help avoid more extensive and expensive jaw surgery later.
Interceptive treatments can also be fairly simple in design like a space retainer, but still have a tremendous impact on bite development. A space maintainer is often used when a primary (“baby”) tooth is lost prematurely, which allows other teeth to drift into the empty space and crowd out the incoming permanent tooth. The wire loop device is placed within the open space to prevent drift and preserve the space for the permanent tooth.
To take advantage of these treatments, it’s best to have your child’s bite evaluated early. Professional organizations like the American Association of Orthodontists (AAO) recommend a screening by age 7. While it may reveal no abnormalities at all, it could also provide the first signs of an emerging problem. With interceptive orthodontics we may be able to correct them now or make them less of a problem for the future.

“What can I do about my child's teeth grinding habit?”
It's a common question we get from many concerned parents. Their exasperation involves more than having to wake every night to the annoying sounds coming from their child's bedroom: they're also worried about any potential damage occurring to their teeth.
Teeth grinding and similar habits fall under the umbrella term “bruxism.” In basic terms, bruxism is the involuntary movement of the teeth and jaws not engaged in regular functions like chewing, speaking or swallowing. Bruxism is actually common among pre-adolescent children, considered by many healthcare professionals as normal behavior like thumb sucking.
It's not fully known why children grind their teeth, especially during sleep. Stress can play a part, but many believe it could also be related to immaturity on the part of the neuromuscular system that controls chewing. In some cases it could be linked to sudden arousals from sleep, particularly if the child is prone to airway obstruction causing sleep apnea. And there may be a link with certain medications, especially for hyperactivity disorders like attention deficit hyperactivity disorder (ADHD).
Most children eventually outgrow the habit. If it persists, though, it can contribute to teeth problems. Teeth can withstand a lot of biting force, but when chronically exposed to the higher than normal forces produced during teeth grinding they can begin to wear. Sodas, fruit juices, sports drinks or similar acidic beverages complicate matters because they increase mouth acid that can soften enamel. And besides dental issues, teeth grinding can also cause jaw problems, ear pain and headaches.
If symptoms begin to appear, we can take steps to reduce the effect of teeth grinding, such as a mouth guard worn at night to reduce biting forces and protect against wear. We can also look at curbing consumption of acidic foods and beverages, addressing possible airway obstructions, changing medications or counseling for psychological stress.
As with thumb sucking, there's no cause for immediate alarm if your children grind their teeth. But if it continues on into their later childhood years or begins to affect their health and well-being, we'll need to intervene to prevent further harm.

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.
