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.

When you hear the word “dentures” you probably think of an appliance that replaces all the teeth on a dental arch. But there is another type: a removable partial denture (RPD), which can be a viable option for replacing a few missing teeth.
An RPD rests on the bony gum ridges that once held the missing teeth and are secured with clasps or other attachments to adjacent teeth. While lightweight, RPDs are designed to last for many years — they’re made of vitallium, a light but very strong metal alloy that reduces the RPD’s thickness. Recently, metal-free partial dentures are being used that don’t have the fit or longevity of the vitallium partial dentures, but are considered more of a cosmetic solution.
RPDs are custom-made for each individual patient to accommodate the number, location and distribution of teeth missing throughout the mouth. Their design must also reflect the health and stability of the gums and remaining natural teeth to ensure they won’t move unduly during normal mouth function, and will be as lifelike and unnoticeable as possible.
RPDs have been a mainstay in dentistry for many years and represent a less expensive tooth replacement option than implants or fixed bridgework. But they do have their downsides: because of their method of attachment to the remaining natural teeth they tend to accumulate plaque, which increases the risk of both periodontal (gum) disease and tooth decay. Their fit requires that they attach to the adjacent teeth that will cause some damage and lead to their looseness over time.
If you wear an RPD, there are some things you can do to decrease these problems. First and foremost, you should clean your RPD thoroughly every day, as well as brush and floss your remaining teeth to reduce plaque buildup especially at contact points. Be sure to remove the RPD at night while you sleep. And keep up regular dental visits not only for additional plaque removal but also to allow us to inspect the RPD for problems or wear.
An RPD is a viable option for improving mouth function and restoring your smile after multiple tooth loss. With proper care and maintenance, your RPD can serve you well for many years to come.

Although energy and sports drinks have different purposes, they have one thing in common: they often contain added citric and other acids to improve taste and prolong shelf life. Their high acid content can harm tooth enamel.
Although enamel is the strongest substance in the body, acid can dissolve its mineral content. And although saliva neutralizes acid after eating or drinking and helps restore lost minerals to the enamel, it may not be able to keep up if the mouth remains acidic for a prolonged period of time.
That could happen with both beverage types. While energy drinks have higher acid levels than sports drinks, both are high compared with other beverages.
A recent laboratory experiment studied the two beverages’ effect on tooth enamel. The researchers submerged samples of enamel in six different beverage brands (three from each category) for fifteen minutes, and then in artificial saliva for two hours to simulate mouth conditions. They repeated this cycle four times a day for five days.
At the end of the experiment the enamel in the energy drinks lost on average 3.1 % of their structure, while the sports drink samples lost 1.5%. Although energy drinks appeared more destructive, the acid in both beverages caused enamel damage. Although there are other factors to consider in real life, the experiment results do raise concerns about both beverages’ effect on dental health.
You can, however, minimize the potential harm to your enamel from energy or sports drinks. First, try other beverage choices lower in acid; water, for example, is a natural hydrator and neutral in pH. Try to only drink energy or sports beverages at mealtimes when your saliva is most active. And after drinking, rinse your mouth out with water to dilute any remaining acid.
And although it sounds counterintuitive, wait about an hour to brush your teeth after drinking one of these beverages. Your enamel can be in a softened state before saliva can re-mineralize it, so brushing earlier could remove tiny amounts of enamel minerals.
Taking these steps with energy or sports beverages could help you reduce the chances for enamel erosion. Doing so may help you avoid unnecessary damage to your teeth and overall dental health.
