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.

What are you most looking forward to this summer? Maybe you’re planning a trip to the beach, or a getaway in the woods…maybe even a journey to a faraway city or a foreign land. Wherever your holiday travel leads you, we hope it’s enjoyable and safe. And while you’re packing your bags, don’t forget to take a trio of important items that can help keep your vacation trouble-free: namely, a soft-bristled toothbrush, a tube of fluoride toothpaste, and a roll of dental floss.
If you have been careful about keeping up your oral hygiene all year, you’ve probably already noticed the rewards it can bring—like a sparkling smile, fresh breath, and good dental checkups. But even if you’re planning to get away from it all this summer, don’t take a vacation from oral hygiene. And if your oral hygiene routine could stand some improvement, maybe this is the time to make a fresh start.
Maintaining good oral health while you’re on the go doesn’t have to be a high-tech pursuit. You don’t need broadband service or a good mobile signal; you don’t even need electric power. Running water is nice, but not essential. And all the tools you need can fit easily in a travel bag.
The benefits of good oral hygiene are clear. Brushing twice every day and flossing once a day can effectively fight the bacteria that cause tooth decay and periodontal disease. That’s important any time of year, but perhaps even more so when you’re traveling because it’s harder to keep a healthy diet. Grabbing a sugary drink or a snack to go is convenient, but it provides food for the bacteria that can cause dental diseases; also, the acid in some soft drinks (even diet sodas) can wear away tooth enamel, leaving you with less protection against cavities.
Summer vacations can bring welcome surprises and unforgettable experiences. But needing urgent dental care in an unfamiliar place is the kind of surprise you can do without. So even though you may be far away from the routines of home, don’t take a vacation from your oral hygiene routine. It takes just a few minutes, but it can keep your smile bright and healthy wherever you go.
Orthodontics shares a principle with the classic tug of war game: if you want things to move in the right direction you need a good anchor. Anchors help braces and other appliances apply constant pressure to misaligned teeth in the direction they need to go to correct a malocclusion (poor bite).
Orthodontic treatments work in cooperation with an existing oral mechanism that already moves teeth naturally in response to biting forces or other environmental factors. The key to this mechanism is an elastic tissue known as the periodontal ligament that lies between the tooth and the bone. Besides holding teeth in place through tiny attached fibers, the ligament also allows the teeth to move in tiny increments.
Braces’ wires laced through brackets affixed to the teeth exert pressure on them in the desired direction of movement –the periodontal ligament and other structures do the rest. To maintain that pressure we need to attach them to an “anchor”—in basic malocclusions that’s usually the back molar teeth.
But not all malocclusions are that simple. Some may require moving only certain teeth while not moving their neighbors. Younger patients’ jaws and facial structures still under development may also need to be considered during orthodontic treatment. That’s why orthodontists have other anchorage methods to address these possible complications.
One example of an alternate anchorage is a headgear appliance that actually uses the patient’s skull as the anchor. The headgear consists of a strap running around the back of the head and attached in front to orthodontic brackets (usually on molar teeth). The pressure it exerts can trigger tooth movement, but it can also help influence jaw development if an upper or lower jaw is growing too far forward or back.
Another useful anchorage method is a tiny metal screw called a temporary anchorage device (TAD) that is implanted into the jawbone above the teeth through the gums. Orthodontists then attach elastic bands between implanted TADs and specific braces’ brackets or wires to exert pressure on certain teeth but not others with pinpoint accuracy. After treatment the TADs can be easily removed.
Using these and other appliances allows orthodontists to customize treatment to an individual patient’s particular malocclusion. With the right anchor, even the most complex bite problem can be transformed into a beautiful and healthy smile.
