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.

People often put a premium on appearance when deciding whether or not to replace a missing tooth. There's more motivation to replace one in the “smile zone,” where the teeth are more visible, than one that's not.
But even if your missing tooth is in the back out of sight, there are still good reasons to replace it. That's because even one lost tooth can have a cascading ill effect on other teeth, the underlying bone or eventually your entire facial structure.
The chief problems caused by a missing tooth occur first with the bone. The act of chewing generates pressure around the teeth. The teeth transmit this pressure through the roots to the bone, which stimulates the bone to grow and remain strong in support of the teeth. When you lose a tooth, the bone no longer receives this growth stimulation.
In time, the replacement rate for older bone cells will slow down and cause the bone volume to decrease. It's possible to detect a change just months after losing a tooth: you can lose an estimated 25% of bone width in the first year.
As the bone diminishes, the jaw loses height and then more width. The gum tissues will also gradually decrease. As a result you may not be able to chew or even speak as well as you once could. Depending on the number of teeth you've lost, the foundational portion of the jawbone — the basal bone — may also decline. The distance between nose and chin may decrease and the cheeks sink in. Without bone support in the rear, the bite can collapse and push the teeth forward out of their normal position.
The best way to avoid this debilitating spiral is to replace a tooth as soon as practical. There are many options, but perhaps the best choice is a dental implant: not only will it provide a life-like appearance, but its affinity with bone will stop bone loss and even encourage new growth.
So, don't neglect replacing that “invisible” tooth if it's lost. Your mouth and ultimately your appearance will be better for it.

You brush and floss every day to rid your teeth and gums of disease-causing plaque. But while “showing up” is most of the battle, the effectiveness of your technique will win the war.
So, how good are you at removing plaque? One quick way to find out is the “tongue test”—simply rub your tongue along your teeth: they should feel smooth and “squeaky” clean. Surfaces that feel rough and gritty probably still contain plaque.
For a more thorough evaluation, your dental hygienist may use a product during your regular dental visit called a plaque disclosing agent. It’s a solution applied to your teeth that dyes any bacterial plaque present on tooth surfaces a certain color while leaving clean surfaces un-dyed. The disclosing agent shows you where you’re effectively removing plaque and where you’re not.
These products aren’t exclusive to the dental office—you can use something similar at home if you’d like to know how well you’re doing with your hygiene before your next visit. You can find them over-the-counter as tablets, swabs or solutions. You may even find some that have two dye colors, one that reveals older plaque deposits and the other newer plaque.
You simply follow the product’s directions by first brushing and flossing as usual, then chewing the tablet, daubing the swab on all tooth and gum surfaces, or swishing the solution in your mouth like mouthwash for about 30 seconds before spitting it out. You can then use a mirror to observe any dye staining. Pay attention to patterns: for example, dyed plaque scalloping along the gum line means you’ll need to work your brush a little more in those areas.
The dye could color your gums, lips and tongue as well as your teeth, but it only lasts a few hours. And while plaque disclosing agents are FDA-approved for oral use, you should still check the ingredients for any to which you may be allergic.
All in all, a plaque disclosing agent is a good way to occasionally check the effectiveness of your plaque removal efforts. By improving your technique you may further lower your risk of dental disease.
