Just What Is Plaque?

October 17th, 2025

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. Elizabeth Hite, DMD, MS 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 Edwardsville 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.

What is hyperdontia?

October 17th, 2025

When a child is born, he or she will have 20 primary teeth and 32 permanent teeth. But sometimes kids are born with additional teeth, and our team at Bauer Hite Orthodontic Specialists calls this oral condition "hyperdontia." Primary teeth are the first set of teeth that erupt in your child's mouth, typically by the time they are 36 months old, and are shed by the time your child reaches the age of 12. Permanent teeth then take the place of the primary teeth and are usually fully-erupted by the time your son or daughter reaches 21 years of age. Anyone who develops more than 20 primary teeth or more than 32 permanent teeth has hyperdontia, and the additional teeth are referred to as supernumerary teeth.

While the cause of hyperdontia is not entirely clear, it is believed that there may be a genetic factor. Oral professionals have found that patients with extra teeth often have syndromes like cleidocranial dysplasia, Ehler-Danlos syndrome, Gardner syndrome, or cleft lip and palate. The prevalence of hyperdontia affects between one and four percent of the population in the United States, and the majority of cases are limited to a single tooth.

So, what is the best way to deal with hyperdontia? It really depends on the case. The treatment plan your doctor suggests varies according to the potential problem posed by the supernumerary teeth, as well as their type. Orthodontic treatment may certainly may help, but extraction can also be a good option. We recommend that children receive an oral evaluation or checkup no later than the age of seven. In addition to hygiene evaluation, this helps ensure your child does not experience hyperdontia problems.

If you suspect you or your child may be suffering from hyperdontia, please give us a call to schedule an appointment at our convenient Edwardsville office to be evaluated.

October Is Orthodontic Health Month!

October 16th, 2025

October’s here! A month when we celebrate the beauty of fall, the taste of pumpkin spice, the fun of Halloween in Edwardsville, and the healthy smiles which orthodontic treatment makes possible!

Because October is Orthodontic Health Month, and it’s a great time to talk about how your orthodontist helps you create not just a more beautiful smile, but a healthier one. 

Straight, evenly spaced teeth are the visible benefit of treatment, but there are many health benefits which might not be quite as noticeable. Orthodontic treatment can:

  • Help You Prevent Cavities and Gum Disease 

When teeth are crowded or crooked, it’s hard for your toothbrush and floss to reach all of the plaque which builds up on and between your teeth. The bacteria in plaque create acids which start to dissolve tooth enamel. And a very small hole in the enamel surface can grow until it becomes a cavity. 

Plaque and bacteria also irritate the gums. When you can’t remove plaque completely, your gums are at risk for gingivitis. This early stage of gum disease causes redness, tenderness, swelling, and bleeding. Left untreated, gingivitis can develop into more serious gum disease. 

And, over time, plaque hardens and becomes tartar, which needs to be removed by a dental professional.

When your teeth are straight and evenly spaced, brushing and flossing are both easier and more effective, helping you keep your teeth and gums healthy and plaque-free.

  • Create a Better Bite

For a healthy bite, your teeth and jaws need to align correctly. The top teeth should slightly overlap the lower teeth, and the ridges of your upper molars should fit smoothly with the grooves of your lower molars. 

Malocclusions, or bad bites, can come in many forms, including overbites, underbites, open bites, cross bites, and overjets. A bad bite is bad for your dental health. Malocclusions can cause tooth grinding, worn enamel, and even cracked teeth. 

And bad bites don’t just affect your teeth. When your bite doesn’t align properly, you might suffer from problems such as headaches, jaw pain, indigestion, and sleep apnea. 

Orthodontic treatment creates a healthy, symmetrical, and pain-free bite.

  • Improve Your Self-Confidence

We can’t forget the invisible health benefits of orthodontic treatment! Your smile is a gift which you share with the world. But if you’re hesitating to smile because of self-consciousness about your teeth or bite, orthodontic treatment can make a world of difference.

Dr. Elizabeth Hite, DMD, MS can help you achieve straighter teeth, a bite which fits together properly, and, when malocclusions affect jaw symmetry, a more balanced facial profile. If you’re concerned about the appearance of your smile, ask Bauer Hite Orthodontic Specialists for an orthodontic consultation. Today’s technology can even let you see what your future smile will look like!

Modern orthodontic treatment is more effective and takes less time to complete than ever before. And orthodontics offers patients of all ages more benefits than ever before: 

  • New types of braces are less noticeable and more comfortable than older styles. Smaller brackets, brackets which blend with tooth enamel, clear aligners, and lingual braces give you a variety of options to customize your treatment.
  • Early orthodontic treatment can guide jaw growth in younger children. 
  • Appliances can help with jaw alignment in older children, or, for more serious malocclusions, an orthodontist can coordinate treatment with an oral surgeon.
  • Treatment isn’t limited to the teen years. Adults make up a large and growing number of orthodontic patients. 

If you’ve been considering orthodontic treatment, October—or any month!—is a great time to schedule a visit with an orthodontist. An orthodontic evaluation will let you know just what your orthodontist can do to help you create a beautiful and healthy smile.

Crushing the Ice-Chewing Habit

September 24th, 2025

It's a habit many people have and not only can it be annoying to the people around you, it can be detrimental to your dental health. Chewing ice is so common that it even has its own name, pagophagia. We're not talking about a slushy or shaved ice (although those artificially sugary treats should be avoided too!) but more like the hunks of ice rattling around in the bottom of your glass.

Ice chewing can be a sign of emotional problems like stress or obsessive-compulsive disorder, but it can also be a marker for iron deficiency anemia and other physical problems. Then again, some people just like to have something to chew on. For whatever reason you find yourself chewing on it, it's a habit you need to break.

Chewing on ice can cause:

  • Chipped and cracked teeth
  • Damaged enamel
  • Sore jaw muscles
  • Damage to dental work such as crowns, fillings, or other appliances

If chewing on ice is becoming a problem in your life, don’t hesitate to speak with Dr. Elizabeth Hite, DMD, MS about it. But if you find yourself still wanting to chew on something, here are a few alternatives to ice:

  • Baby carrots
  • Celery sticks
  • Sugar-free (xylitol) gum

We know you need to chill sometimes, but chomping down your entire glass of ice is not the way to do it. If you have any other questions on the topic, feel free to talk with a member of our Edwardsville team. It may be beneficial in solving the issue and helping to remediate any damage to your teeth.
