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.

It’s common for kids to be less than enthusiastic about visiting the dentist. For some, though, it’s even more of a challenge: A child with extreme anxiety and fear during dental visits could interfere with them receiving the dental care they need. The impact could even extend into adulthood.
Recognizing the need to reduce this high anxiety, dentistry has used a number of pharmacological tools for many years that relax a child during dental care. Sedatives have often been the only choice for reducing anxiety, especially during extensive procedures and treatments. But now there’s a promising new approach in dentistry that doesn’t depend on drugs.
Cognitive behavioral therapy (CBT), a psychotherapeutic method used for decades to treat depression, phobias and eating disorders, has been investigated recently as a possible approach for relieving children’s dental anxiety. During CBT, trained therapists use specific behavioral techniques to help patients develop mental and emotional strategies for dealing with stress.
During the usual course of CBT therapy, a therapist meets in counseling sessions with patients weekly over several months to help them change their routine thinking or behavior surrounding a stressful issue. Initially, the therapist guides the patient toward understanding the underlying causes for their negative reaction to the issue. They then work with the patient to devise an objective way to test whether those emotions and beliefs about the issue are true.
Using this effective method for changing behavioral and emotional responses for dental anxiety has had encouraging results from initial research. One study found CBT successfully reduced dental anxiety among a majority of a group of European children ages 9 through 16 who participated in the method.
CBT isn’t an overnight cure, often requires a number of months to achieve results. But for children who suffer from extreme fear of professional dental care, this drug-free method may provide long-term benefits that extend well past their childhood years.
Most dental procedures today only require local anesthesia to numb just the affected area. It's a safer approach than general anesthesia: the unconscious state created by putting someone "to sleep" can lead to some unpleasant complications.
But patient comfort involves more than preventing physical pain during a procedure. There's also the emotional factor—many people experience nervousness, anxiety or fear during dental visits. It's especially problematic for an estimated 15% of the population whose dental visit anxiety is so great they often try to avoid dental care altogether.
One option is to use general anesthesia for patients with acute anxiety rather than local anesthesia. This removes them consciously from their anxiety, but they must then be monitored closely for complications.
But there's a safer way to relax patients with high anxiety called intravenous or IV sedation. The method delivers a sedative medication directly into a patient's bloodstream through a small needle or catheter inserted into a vein. The sedative places the patient in a relaxed "semi-awake" state, taking the edge off their anxiety while still enabling them to respond to verbal commands.
Coupled with local anesthesia, they won't experience any pain and very little if any discomfort. And many of the sedatives used also have an amnesiac effect so that the patient won't remember the procedures being performed.
IV sedation does require monitoring of vital signs, but the patient won't need help maintaining their breathing or heart function. And although the medication can be adjusted to reduce any lingering after-effects, a patient will still need someone to accompany them to and from their visit.
For lesser anxiety or nervousness, dentists sometimes prescribe an oral sedative to take just before a visit. This can help take the edge off your nerves and help you relax. With either method, though, sedation can help you overcome fear and anxiety and have a more pleasant treatment experience.

Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.
Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.
A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.
During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.
Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.
As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.
If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.
It’s July—and that means it’s National Park and Recreation Month! If you’re like a lot of families, you might already be planning a trip to one of the nation’s 58 national parks, or one of the thousands of state outdoor recreational areas across the country.
Temporarily escaping the stresses of daily life in the great outdoors is a wonderful way to refresh both the soul and the body. But that’s not an excuse to neglect all your responsibilities. That includes making provisions to care for your teeth while you’re away from home—you are bringing them with you, aren’t you?
Here are three ways you can take care of your teeth during your outdoor getaway.
Keep up your daily hygiene. While you’re packing extra socks, granola and moleskin, be sure to include your toothbrush, toothpaste and floss. Just a few days of neglecting your regular oral hygiene can give bacterial plaque a chance to build up. You could even come back from your trip with the beginnings of gingivitis, an early form of gum disease. If you’re trying to pack light, take along travel-size toothpaste tubes or pre-threaded floss picks to make it easier.
Eat dental-friendly snacks and food. Escaping your usual dietary choices doesn’t mean you should take a vacation from good nutrition. Whether you’re in camp or on the trail, eat whole fruits, grains or cheeses, and avoid snacks and foods with added sugar that feeds disease-causing bacteria in the mouth. The same goes for beverages—keep your intake of sodas and sports or energy drinks (all loaded with added sugar and acid) to a bare minimum. Instead, hydrate with water.
Be prepared for emergencies. Exploration through hiking, canoeing and other physical activities is a great part of the outdoor park experience. But it also increases your risk of injury, especially in rough terrain. Before you head out, take some time to research medical and dental resources near your vacation destination in case you or a family member will need immediate care. Having that information handy can save time in the event of an emergency.
An outdoor park trip can be the experience of a lifetime. Just be sure to follow these simple tips to care for and protect your teeth. Doing so will help ensure that your memories of this summer’s outing will be pleasant ones.
