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.

The red, scaly rash suddenly appearing on your face doesn’t cause you much physical discomfort, but it’s still embarrassing. And to make matters worse treating it as you would other skin ailments seems to make it worse.
Your ailment might be a particular skin condition known as peri-oral dermatitis. Although its overall occurrence is fairly low (1% or less of the population worldwide) it seems to be more prevalent in industrialized countries like the United States, predominantly among women ages 20-45.
Peri-oral dermatitis can appear on the skin as a rash of small red bumps, pimples or blisters. You usually don’t feel anything but some patients can have occasional stinging, itching or burning sensations. It’s often misidentified as other types of skin rashes, which can be an issue when it comes to treatment.
Steroid-based ointments that work well with other skin ailments could have the opposite effect with peri-oral dermatitis. If you’re using that kind of cream out of your medicine cabinet, your rash may look better initially because the steroid constricts the tiny blood vessels in the skin. But the reduction in redness won’t last as the steroid tends to suppress the skin’s natural healing capacity with continued use.
The best treatment for peri-oral dermatitis is to first stop using any topical steroid ointments, including other-the-counter hydrocortisone, and any other medications, lotions or creams on it. Instead, wash your skin with a mild soap. Although the rash may flare up initially, it should begin to subside after a few days.
A physician can further treat it with antibiotic lotions typically containing Clindamycin or Metronidazole, or a non-prescription, anti-itch lotion for a less severe case. For many this clears up the condition long-term, but there’s always the possibility of relapse. A repeat of this treatment is usually effective.
Tell your dentist if you have recurring bouts of a rash that match these descriptions. More than likely you’ll be referred to a dermatologist for treatment. With the right attention—and avoiding the wrong treatment ointment—you’ll be able to say goodbye to this annoying and embarrassing rash.
More than 20 million people in the United States use electronic cigarettes or e-cigs as an alternative to tobacco smoking. While many users believe "vaping" is a healthier alternative to regular cigarettes, recent research into the health effects of e-cigs could put a damper on that belief. There's particular concern among dentists that this popular habit could harm users' dental health.
E-cigs are made with a chamber that holds the liquid vaping solution and a heating mechanism to heat the liquid and vaporize it. Users inhale the vapor, which contains nicotine and flavorings, as they would a traditional cigarette.
The nicotine alone can be problematic for dental health as we'll see in a moment. But the vapor also contains aerosols that some research indicates could damage the inner skin linings of the mouth in a similar fashion to the smoke of traditional cigarettes. One study by researchers with the Université Laval in Quebec, Canada found evidence that e-cig vapor increased the death rate of mouth cells, and led to greater cell irregularities over time.
According to other studies, there's evidence that e-cig vapor may disrupt the balance of the oral microbiome, the communities of both beneficial and harmful bacteria that normally live in the mouth. The imbalance in favor of more harmful bacteria could increase the risk for dental disease, particularly periodontal (gum) disease.
Finally, nicotine from e-cigs seemed to create similar conditions in the mouth as it does with tobacco. Nicotine in any form can constrict blood vessels and reduce the body's ability to fight infection and to heal. Research indicates both forms of nicotine increase the risk for dental disease and make treatment more difficult.
These findings only identify conditions created by e-cigs that could be problematic for future dental health. Although we don't fully understand the long-term health effects of this new habit, based on the evidence so far the mouth may not fare so well. It's looking like e-cigs may be no safer for your teeth and gums than the cigarettes they replace.
