Orthodontics shares a principle with the classic tug of war game: if you want things to move in the right direction you need a good anchor. Anchors help braces and other appliances apply constant pressure to misaligned teeth in the direction they need to go to correct a malocclusion (poor bite).
Orthodontic treatments work in cooperation with an existing oral mechanism that already moves teeth naturally in response to biting forces or other environmental factors. The key to this mechanism is an elastic tissue known as the periodontal ligament that lies between the tooth and the bone. Besides holding teeth in place through tiny attached fibers, the ligament also allows the teeth to move in tiny increments.
Braces’ wires laced through brackets affixed to the teeth exert pressure on them in the desired direction of movement –the periodontal ligament and other structures do the rest. To maintain that pressure we need to attach them to an “anchor”—in basic malocclusions that’s usually the back molar teeth.
But not all malocclusions are that simple. Some may require moving only certain teeth while not moving their neighbors. Younger patients’ jaws and facial structures still under development may also need to be considered during orthodontic treatment. That’s why orthodontists have other anchorage methods to address these possible complications.
One example of an alternate anchorage is a headgear appliance that actually uses the patient’s skull as the anchor. The headgear consists of a strap running around the back of the head and attached in front to orthodontic brackets (usually on molar teeth). The pressure it exerts can trigger tooth movement, but it can also help influence jaw development if an upper or lower jaw is growing too far forward or back.
Another useful anchorage method is a tiny metal screw called a temporary anchorage device (TAD) that is implanted into the jawbone above the teeth through the gums. Orthodontists then attach elastic bands between implanted TADs and specific braces’ brackets or wires to exert pressure on certain teeth but not others with pinpoint accuracy. After treatment the TADs can be easily removed.
Using these and other appliances allows orthodontists to customize treatment to an individual patient’s particular malocclusion. With the right anchor, even the most complex bite problem can be transformed into a beautiful and healthy smile.

It’s been a long road back to oral health for you after periodontal (gum) disease. But after several plaque removal sessions and perhaps even surgical procedures to address deep infection, your gums have regained their healthy pink appearance.
But now you must face a hard reality: because you’ve had gum disease you’ll need to be extra vigilant with your oral hygiene to avoid another round with this destructive disease. But don’t worry—you won’t have to fight your prevention battle alone. We’ll continue to provide you care that reduces your risk of re-infection. We call that care periodontal maintenance (PM).
The heart of PM care involves regular dental visits for monitoring, cleanings and treatment when necessary. While most patients may visit their dentist at least twice a year, as a previous gum disease patient we may advise more frequent visits, especially if you’ve just finished periodontal treatment. Depending on the extent of your disease, we may begin with a visit every other week or once every two to three months. If your mouth continues to be disease-free we may suggest increasing the time between visits.
During your visit we’ll carefully examine your mouth, as well as screen you for any signs of potential oral cancer. We’re looking for both signs of re-infection or new issues with your teeth and gums. We’ll also assess the effectiveness of your oral hygiene efforts and advise you on ways you can improve.
If we find any signs of disease, we’ll then formulate a treatment plan to effectively deal with it. With frequent visits we have a better chance of discovering re-infection early—and the earlier the better to minimize any further damage. We may also need to take steps to make future PM care easier. This could include gum surgery to alter the tissues around certain teeth for easier access for examination and cleaning.
Our main focus with PM care is to look ahead: what can we do now to prevent a future bout of gum disease or at least lessen its effect? With continued monitoring and care we can drastically reduce your risk for further damage from this destructive disease.

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.

Find out why dental fillings are necessary and how they can improve your oral health.
Did our St. Peters, MO, family dentist, Dr. Amanda Hillis, just discover a cavity during your last dental checkup? If so, don’t fear; a dental filling is here! Sure, no one revels in the idea of needing dental work but with composite resin dental fillings not only will you get a restored tooth but you won’t even notice that you have a filling.
Why do I need a dental filling?
A dental filling is a special dental material that is used to replace decayed tooth enamel once it’s been removed. As you might imagine, you can’t just leave a tooth after it’s been treated for a cavity. Not only does it weaken the tooth, leaving it prone to further damage, but also it affects the tooth’s appearance. I think we can all agree that no one wants holes in their teeth. A dental filling is the only way to fill these holes left by the removed decay to restore the tooth.
What are the benefits of a composite resin dental filling?
Composite resin is a malleable tooth-colored material that can be placed and shaped to fill these holes in the treated tooth. Before the resin is even placed our St. Peters dentist will choose the proper shade of material to make sure that it blends in with the rest of the tooth. A composite resin filling will ensure that no one will even notice that you have a filling (even you!).
One of the most important benefits of getting a composite dental filling is that it will restore the strength and durability of the tooth. In fact, a filling could almost fully restore the tooth back to its original resiliency. This will ultimately prevent the tooth from weakening over time, which can lead to cracks and fractures.
Composite resin fillings can last up to seven years or more before needing to be replaced. Of course, the longevity of your fillings depends on you. This means, taking good care of your teeth. Don’t use teeth as tools to open up plastic packaging or other items (leave that for scissors). By not putting your filling through excessive wear and tear you could have it for a decade or more. Also, make sure that you are coming in to visit your dentist every six months for routine checkups to check the health of your filling.
