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.

Have you ever felt a hot, burning sensation in your mouth—like it had been scalded—but you didn't eat or drink anything that could have caused it?
While you may think you’re hallucinating, there’s another possibility: Burning Mouth Syndrome (BMS). This condition, which can last for years, produces sensations in the mouth of not only scalding or burning, but also tingling, numbness and a decline in your ability to taste. Patients may feel it throughout their mouth or only in localized areas like the lips, tongue or inside the cheeks.
The exact cause of BMS is also something of a mystery. It’s been theoretically linked to diabetes, vitamin or mineral deficiencies and psychological problems. Because it’s most common among women of menopausal age hormonal changes have been proposed as a factor, although hormone replacement therapy often doesn’t produce any symptomatic relief for BMS.
To complicate matters, other conditions often share the condition’s effects, which need to be ruled out first to arrive at a BMS diagnosis. A feeling of scalding could be the result of mouth dryness, caused by medications or systemic conditions that inhibit saliva flow. Some denture wearers may display some of the symptoms of BMS due to an allergic reaction to denture materials; others may have a similar reaction to the foaming agent sodium lauryl sulfate found in some toothpaste that can irritate the skin inside the mouth.
If these other possibilities can be ruled out, then you may have BMS. While unfortunately there’s no cure for the condition, there are ways to lessen its impact. There’s even the possibility that it will resolve itself over time.
Until then, keep your mouth moist by drinking lots of water or using saliva-stimulating products, limiting alcohol, caffeinated drinks or spicy foods and refraining from smoking. If you’re taking medications that could cause dry mouth, speak with your physician about changing to an alternative. And try to reduce stress in your life through exercise, mindfulness practices or support groups.
While BMS isn’t considered harmful to your physical health it can make life less enjoyable. Careful symptom management may help improve your quality of life.

It’s important for your child’s current and future health that we watch out for tooth decay. Taking x-rays is a critical part of staying one step ahead of this common disease.
But while x-ray imaging is commonplace, we can’t forget it’s still a form of radiation that could be potentially harmful, especially for a child whose tissues are rapidly developing. We must, therefore, carefully weigh the potential benefits against risk.
This concern has given birth to an important principle in the use of x-rays known as ALARA, an acronym for “As Low As Reasonably Achievable.” In basic terms, we want to use the lowest amount of x-ray energy for the shortest period of time to gain the most effectiveness in diagnosing tooth decay and other conditions.
A good example of this principle is a common type of radiograph known as a bitewing. The exposable x-ray film is attached to a plastic devise that looks like a wing; the patient bites down on it to hold it in place while the x-ray exposure takes place. Depending on the number of teeth in a child’s mouth, an appointment usually involves 2 to 4 films, and children are typically spaced at six months apart. Frequency of x-rays depends on your child’s tooth decay risk: lower risk, less need for frequent intervals.
Each bitewing exposes the child to 2 microsieverts, the standard unit for radiation measurement. This amount of radiation is relatively low: by contrast, we’re all exposed to 10 microsieverts of background radiation (natural radiation occurring in the environment) every day or 3,600 microsieverts annually. Even two appointments of four bitewings each year is a fraction of a percent of the background radiation we’re exposed to in the same year.
This conservative use of x-rays is well within safe parameters for children. As x-ray technology continues to advance (as with the development of digital imaging) we anticipate the exposure rate to diminish even more. Prudently used, x-rays remain one of our best tools for ensuring your child’s teeth are healthy and developing normally.
