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 longer many health problems go on, the worse they become. Treating them as early as possible could stop or slow their development.
That holds true for poor bites: while we can certainly correct them later in life, it's often better to "intercept" the problem during childhood. Interceptive orthodontics attempts to do this with treatments that influence how the jaws and other mouth structures develop during childhood. Many of these techniques are usually best implemented before puberty.
For example, some very complex problems called cross bites can occur if the upper jaw grows too narrowly. We might be able to stop this from happening by using an orthodontic appliance called a palatal expander during the childhood years. It works because the bone at the center of the palate (roof of the mouth) has a gap running back to front until the early teens when the gap closes.
We fit the palatal expander up under and against the palate, then extend out metal arms from a center mechanism to the back of the upper teeth that exert outward pressure on them. This widens the center gap, which the body continually fills with bone as the device gradually exerts more pressure. Over time this causes the jaw to widen and lessens the cross bite. Timing, though, is everything: it's most effective before the gap closes.
Another way to aid jaw growth is a Herbst appliance, a hinged device that alters the movement of the jaws. As a child wears it, a Herbst appliance draws the lower jaw forward to develop more in that direction. Like the palatal expander, it's best used before significant jaw growth occurs.
These are just two examples of techniques and tools that can guide structural growth and prevent bite problems. Because they're most effective in the early years of oral development, your child should undergo an orthodontic evaluation as early as age 6 to see if they need and can benefit from an interceptive treatment.
Interceptive orthodontics can stop or at least slow a growing bite problem. The effort and expense now could save you much more of both later on.

The sooner you get treated for tooth decay, the less likely you'll lose your tooth. That could mean a simple filling—or you might need a root canal treatment if decay has reached the inner pulp.
There's also another procedure for advanced decay called pulp capping. It's a bit more involved than filling a cavity but less so than a root canal. We can use it if decay has exposed or nearly exposed the pulp, but not yet infected it—otherwise, you may still need a root canal treatment to remove the diseased pulp tissue.
There are two types of pulp capping methods, direct and indirect. We use direct pulp capping if the pulp has been exposed by decay. After isolating the tooth to protect other teeth from contamination, we remove all of the decayed dentin up to the pulp. This may cause some bleeding, which we'll stop, and then clean and dry the tooth area.
We'll then apply a protective biocompatible material directly over the pulp to promote healing and protect it from further infection. We then restore the tooth's appearance and function with a life-like filling.
We use the indirect method, a two-part process separated by six to eight months, when the pulp tissue is close to the surface but not yet exposed. We initially remove the majority of decayed tooth structure, but leave some of it in place next to the pulp chamber. Although this remaining dentin is softened and decayed, we'll treat it with antibacterial chemicals, then cover it with a biocompatible material and a temporary filling.
Over the next several months the treated structure has a chance to re-mineralize as it heals. We then remove the temporary filling and assess the level of healing progress. If the regenerated dentin appears healthy, we can then remove any remaining decay and restore the teeth as we would after a direct pulp capping.
At the very least, pulp capping could buy your affected tooth time before a root canal will finally be needed. Under the right circumstances, it's an effective way to save an otherwise lost tooth.
