Midline Misalignment

June 28th, 2023

By and large, the human body is a marvel of symmetry. But, of course, no one is perfect. You might have noticed one ear is a bit higher than the other. That you wear a shoe a half-size bigger on your left foot. That one shirtsleeve always looks longer.

Or that your smile looks off-center. This dental asymmetry could be caused by a condition known as “midline misalignment,” and, unlike that left foot, you can do something about it!

The dividing line between our center teeth, upper and lower, is called the midline. If we draw an imaginary line down the middle of a face, from the forehead to the nose to the midpoint of the chin, that line should go right between the front teeth. When it doesn’t, because the teeth have shifted past the midpoint, it’s often due to a condition called midline misalignment.

This kind of misalignment, also known as a deviated midline, can have several causes:

  • Baby teeth that are lost too early

Baby teeth do more than promote healthy eating and speech development. They also reserve space for permanent teeth. If a primary tooth is lost too early, permanent teeth might “drift” to fill the empty space, causing the midline to move as well.

  • Thumb sucking that goes on too long

As a child gets older, and certainly when by the time permanent teeth start to arrive, aggressive thumb sucking can lead to numerous orthodontic problems, including a deviated midline, as the teeth shift in response to that continuous pressure.

  • Missing adult teeth

When you lose a tooth through decay or trauma, or when an adult tooth simply never develops, the remaining teeth can shift over to fill the open spot.

  • Spacing issues

Crowded teeth, teeth with significant gaps between them, very large teeth, very small teeth—all of these issues can affect spacing and midline alignment.

  • Crossbite

A crossbite is a kind of malocclusion, or bite problem. When you have a crossbite, the teeth don’t fit together properly, with upper teeth fitting inside lower teeth, instead of aligning on the outside where they belong. A deviated midline can indicate a posterior crossbite, where the top back teeth slant inwards or fit inside the bottom back teeth.

A tiny bit of midline shift one way or the other might be nothing to worry about, but if one front tooth is literally the center of attention, or if your teeth are noticeably out of alignment, it’s a good idea to talk to our Lewis Center orthodontic team.

Because there are several potential causes for midline misalignment, Dr. Carr will carefully analyze your individual situation to determine where the problem lies: with the teeth, the bite, or, rarely, the jaw itself.

Dr. Carr will also offer you your best dental treatment options. A shift of a few millimeters might be treated with clear aligners or traditional braces. A crossbite could require braces or aligners coupled with elastics (rubber bands) to bring your bite into alignment. A palatal expander can help correct a serious crossbite.

Why visit Carr Orthodontics because of a little asymmetry? Because a deviated midline is more than a cosmetic concern. If you have a malocclusion to begin with, or if your misalignment leads to changes in chewing habits, which cause new bite problems, you might be facing jaw pain, chipped and cracked teeth, headaches, and all the other unpleasant consequences of malocclusion.

By and large, perfect symmetry in life is unattainable. But if you want a smile that is well-balanced and healthy, talk to us about all the treatments available to make sure your smile—and not a single tooth—is the center of attention.

Happy Fourth of July

June 28th, 2023

Every year, Americans all over the world celebrate the birth of the country and its independence on the Fourth of July. There are countless ways that people celebrate and they range from community parades and large scale gatherings to concerts, fireworks displays, and smaller scale celebrations among family and friends. For some people, July 4th is synonymous with baseball, while for others it is all about the beach of barbecues. However you celebrate, you can be sure that red, white, and blue is visible everywhere throughout the area.

The Beginnings of Fourth of July Celebrations

Although it wasn't officially designated as a federal holiday until 1941, the actual tradition of celebrating Independence Day goes back to the time of the American Revolution (1775 – 1783). At the time of the American Revolution, representatives from the 13 colonies penned the resolution that ultimately declared their independence from Great Britain. The continental congress voted to adopt the Declaration of Independence on July 2nd of 1776. Two days later, Thomas Jefferson's famous document that is now known as the Declaration of Independence, was adopted by delegates representing the 13 colonies.

First States to Recognize the Fourth of July

In 1781, Massachusetts became the first state (or commonwealth) whose legislature resolved to designate July 4th as the date on which to celebrate the country's independence. Two years later, Boston became the first city to make an official designation to honor the country's birth with a holiday on July 4th. In that same year, North Carolina's governor, Alexander Martin, became the first governor to issue an official state order stipulating that July 4th was the day on which North Carolinians would celebrate the country's independence.

Fun Facts About the Fourth of July

  • The reason the stars on the original flag were arranged in a circle is because it was believed that would indicate that all of the colonies were equal.
  • Americans eat over 150 million hot dogs on July 4th.
  • Imports of fireworks each year totals over $211 million.
  • The first “official” Fourth of July party took place at the White House in 1801.
  • Benjamin Franklin didn't want the national bird to be the bald eagle. He believed that the turkey was better suited to the coveted distinction. John Adams and Thomas Jefferson disagreed with him, and he was outvoted, so the bald eagle became the official bird of the United States.

For many, the tradition is something entirely different. Along the coastal areas of the United States, people may haul out huge pots to have lobster or other types of seafood boils. Others may spend the day in the bleachers at a baseball game, or at a park, cooking a great traditional meal over an open fire. No matter how or where you celebrate, one thing is certain: all Americans celebrate July 4th as the birth and independence of our country.

Dr. Carr and our team at Carr Orthodontics wish you a safe and happy Fourth of July!

Wearing Braces? Make Cavities a Remote Possibility

June 22nd, 2023

Press Pause

If you are getting braces in the near future, it’s very important to see your regular dentist first. That way, any cavities or other dental problems can be treated before your first orthodontic appointment at our Lewis Center office.

Play it Safe

Once you have your braces, you’ll hearing a lot about how you need to be especially careful with your dental hygiene. Why? Because wires and brackets are obstacles to getting your teeth and gum area their cleanest. Plaque and food particles tend to stick to braces, and all too often can be missed while brushing. Plaque builds up around your gum line and brackets, and, in a very short time, can lead to sensitivity, demineralization, and cavities.

What can you do to prevent tooth decay?

  • Increase Your Brushing Time

Instead of brushing twice a day, start brushing for two minutes after every meal. Put together a travel bag with a small toothbrush, toothpaste, floss, and interproximal brushes to clean your teeth when you’re on the go. If you absolutely can’t brush, rinse carefully with water, and then brush as soon as you can.

  • Flossing—More Important than Ever

Use the flossing tools designed just for braces to make sure you’ve removed food particles and plaque from around your braces and gums. A water flosser can be helpful if manual flossing isn’t effective.

  • Keep Up with Your Regular Dental Care

Schedule regular checkups and professional cleanings at your dentist’s office. They will be able to remove plaque you might miss at home.  

  • Follow Our Advice

We’ll give you instructions on how to brush and floss, what products to use, and diet suggestions (such as keeping sugary and sticky foods off the menu and away from your braces). If we notice plaque building up around your gums and brackets, we’ll let you know that you need to step up your hygiene habits. We can also suggest rinses and toothpastes that help fight plaque.

But if, despite all your efforts, you do get a cavity? There are options!

  • Ignoring Your Cavity?

Not an option. You shouldn’t wait until you are out of braces to get a cavity treated. This just gives decay a chance to spread further.

  • Working With Your Braces

Repairing a cavity means removing the decay in the tooth, cleaning the area, and then filling the tooth. If your cavity isn’t located near your bands, brackets, or wires, your dentist might be able to work around your braces, and you can get your cavity treated during a regular dental appointment.

  • Removing Parts of Your Braces for Treatment

Sometimes a cavity is located in a spot that your dentist can’t reach because of your braces. In that case, we’re able to coordinate with your dentist and remove a wire or bracket temporarily so you can have your tooth filled. Make an appointment to replace your bracket and re-attach your wire, and you’ll be back on schedule as soon as possible.

Fast Forward

Keep your eyes on your goal--you’re in braces because you want a beautiful smile. Keeping on top of your dental health is an essential part of creating that smile. Talk to Dr. Carr about tips for getting your teeth their cleanest. If you do develop a cavity, we’ll help you figure out the best way to treat it without causing too much delay in your orthodontic treatment. Taking care of your teeth now is the best way to create a future of beautiful smiles!

Toothbrush Science

June 22nd, 2023

Let’s talk science! From the vastness of the cosmos to sub-atomic particles, science helps us understand the world around us and how it works. So, let’s take some familiar scientific fields of study and apply them to your toothbrush.

My toothbrush?

Yes, indeed! When it comes to your oral health, your toothbrush is the first line of defense, so understanding how and why it works so well might help us use this handy tool even more effectively.

Biology—the study of living organisms

Unfortunately for your toothbrush, the living organisms we’re talking about here are the bacteria which cause tooth decay and those which can lead to illness. How do these problems arise, and how do we prevent them?

Fight Plaque

Plaque is the sticky film that builds up on teeth, and millions of oral bacteria help make up this biofilm. These bacteria convert sugars and other carbohydrates in the foods we eat into acids. And these acids erode our tooth enamel, leading to tooth decay. (More on this when we get to Chemistry.) The best ways to get rid of plaque?

  • Brush often. The recommended minimum is two minutes of brushing twice a day, but when you’re having orthodontic work done, it’s even more important to banish the plaque that can stick to your braces or inside aligners. Ask us what brushing schedule is best for you.
  • Try an electric toothbrush. For some people with braces, cleaning the teeth is easier and more thorough with an electric brush.
  • Replace your brush regularly. Brushes become worn and frayed after three or four months, and you won’t be brushing as effectively.

Stop Germs from Spreading

  • Don’t share. Sharing toothbrushes can lead to an increased risk of colds and infections.
  • Rinse thoroughly after brushing, making sure you remove any toothpaste or debris left after you brush.
  • Store the brush upright and let it air-dry. Covering the brush or keeping it in a closed container can promote the growth of bacteria more easily.
  • Keep different brushes separate when they’re drying to avoid cross-contamination.
  • Replace your brush regularly!

Chemistry—the study of what makes up substances, their properties, and how they interact

When it comes to improving your brushing chemistry, the best thing you can do for your toothbrush is to put a dab of fluoride toothpaste on it! Why fluoride? Let’s look at the chemistry of tooth enamel.

Tooth enamel is the strongest substance in our bodies—even stronger than bone. But it is not indestructible, and acidic substances can dissolve the mineral bonds which give our enamel its strength, whether they come from the bacteria in plaque or are found in our favorite foods and drinks (sodas, coffee, tomatoes, and citrus are among the tasty, but acidic, culprits).

The enamel in our teeth contains calcium and phosphate ions, minerals which help make it the strongest substance in our bodies. But when the level of acidity in our mouths becomes too high, these minerals begin to dissolve. Eventually, teeth become pitted, bacteria can penetrate more deeply, and decay is the result.

So what can we do? While our saliva helps neutralize acidity naturally, and we can cut back on acidic foods in our diets, using fluoride toothpaste actually helps restore the strength of our enamel in a process known as “remineralization.”

Fluoride works on the surface of enamel to both attract and anchor calcium ions, reducing mineral loss and strengthening the weakened enamel. Fluoride also interacts with the calcium and phosphate compound to create a new compound that is even stronger and more acid-resistant.

When you brush with fluoride toothpaste, you help replace and restore the mineral composition of your enamel—and there’s evidence that fluoride might even interfere with oral bacteria’s ability to produce acid. Now that’s good chemistry!

Physics—the study of matter and energy and their interactions

The matter here is your tooth enamel, and the energy is the force you use when brushing. And this is one time the force should not be with you.

  • Over-vigorous brushing can not only damage your brackets, but can also irritate delicate gum tissue and wear down enamel. A “sawing” back-and-forth motion is both hard on your enamel and misses plaque and debris between the teeth. We’ll be happy to show you the safest and most effective way to brush with braces. Just remember, “Massage, don’t scrub.”
  • A soft toothbrush is almost always your best option when you use a manual brush, but if you’re still a heavy-handed brusher, or have sensitive teeth and gums, consider an electric model. An electric toothbrush should provide a continuous brushing motion without needing any heavy pressure from the brusher. Some models will even let you know when you are brushing too hard.

Brushing harder is not brushing better, and your teeth, gums, and braces will be heathier with careful brushing habits. If you need tips on brushing with braces, contact our Lewis Center office and ask!

There’s a lot of science in the simple act of brushing, but we don’t need to spend hours studying to get a passing grade in dental health. The things you do normally—brushing at least two minutes twice a day, using fluoride toothpaste, and applying proper brushing technique—will help create a smile which will earn you top marks from Dr. Carr for a lifetime!
