It can be alarming to be awakened in the middle of the night by a screeching, gritting sound coming from your child’s bedroom. No, it’s not a scene from a horror movie: it’s your child grinding their teeth as they sleep — a behavior so prevalent in children under eleven it’s considered normal.
That doesn’t mean, however, you should completely ignore it. While it isn’t harmful for most children, a few can encounter tooth wear, pain or trouble sleeping that calls for some form of intervention.
The causes for tooth grinding and similar habits known collectively as bruxism aren’t thoroughly understood, but in children it’s believed linked to the immaturity of the neuromuscular system that controls chewing. Some point to shifts from one stage of sleep to another — more than 80% of grinding episodes occur in lighter stages of sleep and only 5% to 10% during the deeper Rapid-Eye-Movement (REM) stage. It also seems prevalent in children who snore or have other symptoms of sleep apnea.
One primary concern is how the behavior can affect teeth, particularly through abnormal wear. The teeth, of course, make hundreds of contacts with each other every day during eating, speaking or jaw movement. If, however, the forces generated during these contacts chronically exceed normal parameters, as with bruxism, it can cause accelerated tooth wear. This can result in a higher susceptibility to tooth decay and appearance changes later in life.
If your child is exhibiting problems associated with teeth grinding, there are ways to address it. We may recommend a thin, plastic mouthguard they wear while sleeping that prevents the teeth from making solid contact with each other. We may also refer you to an ear, nose and throat specialist if we suspect signs of sleep apnea. And, children under severe psychological stress, which can also trigger teeth grinding, could benefit from behavioral therapy.
The good news is most grinding habits fade as children enter their teens. In the meantime, keep a watchful eye and see us if you notice any indications this common habit is affecting their health and well-being.

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

If there’s one essential tool for protecting your dental health, it’s the humble toothbrush. The basic manual brush with a long, slender handle and short-bristled head is still effective when used skillfully. The market, though, is full of choices, all of them touting their brand as the best.
So how do you choose? You can cut through any marketing hype with a few simple guidelines.
First, understand what you’re trying to accomplish with brushing: removing dental plaque, that thin film of bacteria and food particles on tooth surfaces that’s the main cause of dental disease. Brushing also stimulates gum tissue and helps reduce inflammation.
With that in mind, you’ll first want to consider the texture of a toothbrush’s bristles, whether they’re stiff (hard) or more pliable (soft). You might think the firmer the better for removing plaque, but actually a soft-bristled brush is just as effective in this regard. Stiffer bristles could also damage the gums over the long term.
Speaking of bristles, look for those that have rounded tips. In a 2016 study, less rounded tips increased gum recession in the study’s participants by 30%. You should also look for toothbrushes with different bristle heights: longer bristles at the end can be more effective cleaning back teeth.
As far as size and shape, choose a brush that seems right and comfortable for you when you hold it. For children or people with dexterity problems, a handle with a large grip area can make the toothbrush easier to hold and use.
And look for the American Dental Association (ADA) Seal of Acceptance, something you may have seen on some toothpaste brands. It means the toothbrush in question has undergone independent testing and meets the ADA’s standards for effectiveness. That doesn’t mean a particular brush without the seal is sub-standard—when in doubt ask your dentist on their recommendation.
Even a quality toothbrush is only as effective as your skill in using it. Your dental provider can help, giving you tips and training for getting the most out of your brush. With practice, you and your toothbrush can effectively remove disease-causing plaque and help keep your smile beautiful and healthy.
