From the time you were small, you’ve been warned about the dangers of plaque. Why? Because:

• It’s an unpleasant film that sticks to your teeth
• It causes cavities
• It causes gum disease
• It can cause extra problems when you wear braces

And really, do we need to know much more than this to motivate us to brush? But if you’re in a curious mood, you might be wondering just how this soft, fuzzy film accomplishes all that damage. Let’s take a closer look at the sticky problem of plaque.

How does plaque form?

We live with hundreds of species of oral bacteria, most of which are harmless, and some of which are actually beneficial. But when our oral ecosystem gets out of balance, problems can occur. For example, without regular and thorough brushing and flossing, we start to build up plaque.

Plaque starts forming within hours of your last brushing. And even though plaque fits the very definition of “seems to appear overnight,” this biofilm is actually a complex microbial community with several different stages of development.

• It starts with saliva.

Saliva is vital to our oral health, because it keeps us hydrated, washes away food particles, neutralizes acids in the mouth, and provides minerals which keep our enamel strong. Saliva also contains proteins, which help form a healthy, protective film on the tooth surface. This film is called a pellicle.

• Bacteria attach to the pellicle.

There are species of oral bacteria that are able to attach themselves to the pellicle film within hours of its formation. As they become more firmly attached, they begin to grow and divide to form colonies, and are known as the early colonizers of the plaque biofilm.

• A complex biofilm forms.

If you’ve skipped brushing for a few days (please don’t!), you’ll notice a fuzzy, sometimes discolored film on your enamel—that’s a thriving plaque community, and it only takes a matter of days to go from invisible to unpleasant.

If you’re not removing plaque regularly, it can harden further and become tartar. And once you have tartar buildup, you’ll need the care of a dental professional to remove it.

• What happens if we ignore plaque and tartar?

We get cavities and gum disease.

How does plaque cause cavities?

• The bacteria in plaque, like all organisms, need nutrients.

Our normal oral environment and the food in our everyday diets provide the nutrients plaque needs. And, as we mentioned above, certain types of oral bacteria convert these nutrients into acids. Foods such as carbohydrates, starches, and sugars are most easily converted into acids, which is why we recommend that you enjoy them in moderation.

• The biofilm promotes acid production.

Within the plaque film, anaerobic bacteria (bacteria which don’t use oxygen) convert sugars and starches into acids. As the plaque film becomes denser, it blocks acid-neutralizing saliva and oxygen from reaching these bacteria close to the tooth’s surface, creating an ideal environment for the bacteria to produce their acid waste products.

• Acids attack enamel.

The sticky nature of plaque keeps these acids in contact with tooth enamel, where, over time, acids dissolve minerals in enamel, weakening the mineral structure of the tooth.

How does plaque cause gum disease?

• Bacteria cause inflammation and gingivitis.

The bacteria in plaque irritate the delicate tissue of the gums, which causes an inflammation response which can leave your gums swollen, red, bleeding, or tender. This early form of gum disease is gingivitis. Fortunately, good dental care and careful brushing and flossing can usually prevent and even eliminate gingivitis.

• Plaque and tartar can lead to periodontitis.

When plaque and tartar build up around and below the gumline, the gums pull away from the teeth, leaving pockets where bacteria collect, leading to infection as well as inflammation. Infections and constant inflammation not only harm gum tissue, they can destroy the bone supporting the teeth. This serious gum condition is periodontitis, and should be treated immediately to avoid further infection and even tooth loss.

How does plaque affect orthodontic patients?

• Plaque collects around your braces.

Braces provide plenty of spots for plaque to hide from your brush. If you aren’t extremely diligent with your brushing and flossing, plaque collects near brackets, wires, and bands—all those spots that a brush and floss find difficult to reach.

• Plaque promotes demineralization

The demineralization process we mentioned above can cause white spots on teeth (decalcification), where minerals have dissolved. Sometimes these spots can be treated, and sometimes they are permanent. They can become quite sensitive, and may lead to cavities.

Careful brushing and flossing around your braces will help eliminate the plaque that can cause demineralization near brackets. Ask Dr. Mark Guevarra about the tools and the brushing and flossing techniques which will give you the best results.

How do we fight plaque?

From the time you were small, you’ve learned how to fight plaque:

• Brush at least twice a day for two minutes, and be sure to brush all of your tooth surfaces and around the gumline.
• Floss to remove plaque from between the teeth and near the gumline.
• See your dentist as recommended for a thorough professional cleaning.

Be proactive. If you have any questions, talk to us at our Iowa office about the best way to keep plaque at bay. We can show you the most effective ways to brush and floss, recommend anti-plaque toothpastes and rinses, even suggest plaque-revealing tablets if you’re missing some trouble spots.

We’ve only brushed up on some plaque basics, because there is a lot more to discover about this complex biofilm. Happily, even with all there is to learn about plaque’s growth and development, it’s reassuring to know that getting rid of it is quite simple—with just a soft-bristled brush, some dental floss, and a few minutes of your time each day, you’re on the way to a healthy, happy, plaque-free smile.

You’re going to the game! And no matter which sport you follow, there’s so much to enjoy—the best athletes, exciting play, hometown pride—and those delicious concession stands! But if you’re wearing braces, your team spirit might be flagging. Here are a few ideas to help keep your food choices out of foul territory.

You know that you should avoid the foods that can damage braces or stick around your wires and brackets. This means any snacks that are sticky, chewy, hard, or crunchy are benched. So most of the traditional game foods—peanuts, popcorn, nachos, licorice—are just not safe for traditional metal or ceramic braces. Let’s save those for next season.

So what is on the program? You still have many great choices.

• Ice Cream. A favorite that’s easy on your braces (no nuts or caramel, please). If you want a healthier option, try frozen yogurt or a smoothie.
• Hearty Snacks. Pretzels and pizza can be too thick and chewy. Go for the mac and cheese, chili, or deli meats on soft bread. And remember, small bites! Check with us to see if hamburgers and hot dogs are safe for your braces.
• Soft Candies and Cookies. Licorice, caramels, and crunchy cookies are out, but soft chocolate bars and moist, tender cookies are still on the menu.
• Sodas and sports drinks can create a sugary and/or acidic environment which can damage enamel over time. If you do indulge, try to rinse with water ASAP.

Stadium and arena menus contain a lot of starches and sugars, which stick to braces and fuel cavity-causing bacteria. So it’s best to go easy on the snacks. But you don’t have to give up a half-time treat entirely—just enjoy in moderation and be sure to brush thoroughly when you get home.

If you wear clear aligners, your choices are simpler. You can remove your aligners, eat normally, and clean your teeth thoroughly before replacing them. But one flag on this play—remember that you’re supposed to wear your aligners for a set number of hours each day. You don’t want to be putting your treatment behind schedule if the game goes into triple overtime. Keep your eye on the clock, and you should be fine.

Dr. Mark Guevarra and our Iowa team are always happy to recommend the best food options for your individual orthodontic treatment, and we can help you select a roster of safe and healthy choices. You might miss out on a few of your favorite sports snacks right now, but let’s remember the true fan’s motto: There’s always next year! Taking care of your braces and teeth means faster treatment and healthier teeth. Your All-Star smile will be worth it!

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 Iowa 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. Mark Guevarra for a lifetime!

Plaque is a sticky subject! It sticks to the enamel of our teeth above and below the gum line, and it collects around braces. Plaque is one of the major causes of tooth decay and gum disease, and our teeth are under daily attack by this filmy menace.

What are the facts about plaque, and how can we fight back? Read on for some effective strategies!

What Is Plaque?

Plaque is a sticky film that builds up on our teeth, largely made up of millions of different types of oral bacteria. Plaque is a colorless biofilm at first, but as it collects, it takes on a white or yellow tint. If you haven’t brushed for a few days, that fuzziness you feel on your teeth is plaque build-up. Unless it’s removed, plaque hardens within a matter of days to become tartar.

• Tip: You can remove plaque with careful brushing and flossing, but it takes a dental professional to remove tartar. Be proactive!

Why Does Plaque Cause Cavities?

Bacteria in plaque use our food as their food, especially sugars and carbs. They can then transform these nutrients into acids, which attack our tooth enamel, weakening it and leaving it vulnerable to further erosion and eventual decay.

• Tip: Cavities aren’t the only damage caused by accumulated plaque. Plaque also collects along and below the gum line. If tartar forms here, it irritates delicate gum tissue, leading to gingivitis and more serious gum disease. Make sure you don’t forget your gums when you brush and floss.

When Does Plaque Build Up?

The short answer? Plaque is always forming, because oral bacteria are a natural part of our biology. (In fact, there are even oral bacterial which are beneficial.) Plaque starts building up within minutes after eating, and during the night as we sleep.

That’s why we recommend brushing for two minutes at least twice a day, and flossing at least once a day. When you wear braces or aligners, brushing more often is a good idea. Food collecting around braces or inside aligners is a feast for plaque! Ask Dr. Mark Guevarra for suggestions for your best brushing schedule.

• Tip: Just because plaque is unavoidable, that doesn’t mean we need to give the bacteria in plaque any additional encouragement. Every time you have a meal or a snack that’s heavy in carbs and sugars, you are providing more fuel for acid production. Cutting down on foods like sugary desserts and sodas is not only nutrition-healthy, it’s tooth-healthy!

Where Does Plaque Collect?

Plaque builds up all over tooth surfaces, at the gum line, and even below the gum line. It’s especially easy to miss in hard-to-reach places like the irregular surfaces of molars, between the teeth, behind our front teeth, and near the gum line. Plaque also collects around your braces, and requires special care to make sure your teeth don’t suffer cavities or the white spots caused by demineralization.

• Tip: One of the ways plaque avoids detection is its invisibility. Fortunately, if you’re having trouble brushing away all your plaque, there are plaque-disclosing toothpastes and chewable tablets available in the dental aisle which reveal the plaque hiding between, behind, or around your teeth by tinting it with a can’t-miss color. Just brush the color away, and you’ve brushed the plaque away as well.

How Do We Clean Away Plaque?

Use the Right Tools

Floss at least once a day. There are different materials, sizes, and coatings for floss, so you can find one that’s comfortable for you. Floss reaches those spots in between teeth and around the gum line that brushes miss.

Choose a soft toothbrush (soft bristles are better for your enamel) and change it every three to four months, or as soon as the bristles show wear. Make sure the head is the right size—too big, and it’s not only uncomfortable, but you won’t be able to reach all the surfaces you need to.

• Tips: There are special dental flosses created just for your braces. You can also use interproximal brushes water flosser to clean around wires and brackets. If you have trouble removing plaque around your teeth and braces with a manual toothbrush, consider an electric model. Several studies have shown a reduction in plaque with the use of an electric brush.

Use the Right Toothpaste

There are many toothpastes specifically formulated to fight plaque and tartar. And fluoride toothpastes not only fight cavities, they can strengthen your enamel.

• Tip: Studies have shown that toothpastes with baking soda, in particular, are effective in reducing plaque. Ask Dr. Mark Guevarra for a recommendation the next time you’re at our Iowa office.

Use the Right Technique

What not to do?  A forceful, horizontal sawing motion is awkward, hard on your enamel, and misses plaque and debris between the teeth. Technique is important—not for style points, but for cleaner teeth!

Hold your toothbrush at a 45-degree angle, especially at the gum line, to gently remove plaque from teeth and gums. Use short strokes or a circular motion to clean as much of the surface and between the teeth as possible. Brush the inside of your front teeth with careful vertical strokes—remember, that’s one place where plaque is easy to overlook. The same holds true for the tops of your molars, so thoroughly clean those uneven surfaces.

If you wear braces, be sure to clean thoroughly around brackets and wires, where plaque can accumulate quickly.

• Tip: If you wear clear aligners, don’t forget to give them a gentle brushing as well! Plaque can stick to aligners, causing discoloration and odors, so follow our cleaning instructions carefully.

Who Can Help You Fight Plaque?

Even when you do your best at home, plaque can still be a sticky problem. That’s why we advise regular professional cleanings, which not only remove any plaque that’s hiding away, but also eliminate any built-up tartar around your braces. And, of course, there you can learn all about how to keep your teeth their cleanest.

True, you’re fighting plaque every day, but you have all the tools you need to make sure your teeth and gums stay healthy. You’re winning the battle with plaque every time you eat a nutritious meal, and every time you brush and floss. With that kind of strategy, plaque doesn’t stand a chance. And your bright smile and healthy teeth and gums? That’s a victory worth celebrating!
