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

• It’s an unappealing film that sticks to your teeth
• It causes cavities
• It causes gum disease

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 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.
• Visit our Chesterton office for a thorough professional cleaning.

Be proactive. If you have any questions, talk to Dr. McGue 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.

One of the most frequent questions that Dr. McGue and our team hear is about what kinds of snacks are best for a child’s dental health. Sugary snacks are inevitable sometimes, but it’s vital for you as a parent to monitor how frequently your child is eating the kinds of snacks that may give him or her a cavity or two down the line.

Unsurprisingly, the best snacks are healthy ones, though they may not always be the most appealing to your little ones. The good news is that healthy doesn’t mean you have to compromise on taste. Once your kids give these tasty snacks a go, they might become open to all things healthy!

• Fresh veggies and hummus
• Apple wedges with peanut butter
• Low-fat yogurt with berries
• Cubes of cheese and crackers
• Hard-boiled eggs with a little bit of salt and pepper
• Celery sticks with cream cheese and sunflower seeds
• A homemade milkshake with low-fat milk (or almond milk), the fruit of their choice, chia seeds, and cinnamon
• Lean proteins such as chicken breast, fish, and turkey

These snacks aren’t high in sugar but they contain all the nutrients your children need to have the necessary energy throughout the day.

This is only a sample of all the great, healthy snacks out there for your kids. For more ideas, ask us the next time you visit our Chesterton office. It’s never too early to create healthy habits; they’re not only good for oral health, but overall health too. That’s a win-win, if you ask us.

You take a sip of soda – and someone remarks, “That’s going to ruin your teeth!”

Is that true? Is sweet soda the enemy of a healthy smile? The answer, unfortunately, is that one glass might not hurt your teeth, but drinking soda regularly can do some real damage.

Sodas are one of America’s favorite drinks. The American Academy of Cosmetic Dentistry says about half of us drink soda regularly, averaging 2.6 glasses each day.

That’s a lot of soda considering the drinks are acidic, full of sugar, and have little or no nutritional value. It may surprise you to learn that it’s actually the acidity of cola, not the sugar, which poses the biggest threat to teeth. Over time, repeated exposure to soda wears down tooth enamel, leaving teeth stained and less able to prevent cavities.

As enamel wears away, teeth can become discolored, take on a rough texture, and become highly sensitive to hot or cold. Your teeth may start to tingle, and brushing or flossing can cause pain. If not checked by dental care, teeth may start to erode, becoming thinner and more likely to crack. It’s a pretty high price to pay for a glass of soda.

Of course, sodas are not the only culprits in tooth erosion. Coffee, wine, and some fruit juices are also acidic, though these drinks tend to have less acidity that a typical soda.

So what can you do to protect your teeth?

1. Cut back – way back – on acidic drinks.

2. Add more water to your daily diet in place of sodas.

3. Use a straw when you drink.

4. Don’t confuse diet soda with a healthy alternative. Diet drinks are just as acidic as regular sodas.

5. Rinse your mouth with water after drinking soda. The rinse may remove some acid from your teeth, although abstaining from the soda would do more good.

6. Hold off on brushing your teeth after drinking soda. Brushing too hard can weaken enamel that is already covered in acid.

7. Pay attention to your teeth, both how they look and how they feel. Let Dr. McGue know if you see signs of discoloration or erosion, or feel tingling. Make an appointment at our Chesterton office if you feel tooth or gum pain when eating or drinking.

Just because it’s cold out there doesn’t mean you’ll give up keeping fit and active! Winter is the season for some of our favorite team sporting activities, and when you’re donning your protective gear, don’t forget to protect your teeth as well.

• Basketball

This sport actually tallies one of the highest counts of dental injuries. Running, jumping, and diving for the ball on an unforgiving court can lead to tooth and jaw injuries.  And for every ten men on the floor, it seems like there at least 50 flailing elbows in the paint.

• Hockey

Notorious for the toll it takes on teeth, hockey is a game of sticks, ice, and whizzing pucks. And when your sport’s penalties include the terms hooking, slashing, and tripping, the more protection, the better.

• Skiing

When you are flying down the slopes, combining powdery snow and speed, mouth protection is a good idea. This also applies to snowboarding and other snow sports.

• Wrestling

Grappling and pinning in close quarters can lead to unintended injuries after accidental contact with the mat or your opponent.

Different uniforms, different equipment, and different playing fields, but all these sports have one thing in common—the easiest way to protect your teeth while playing them is with a mouth guard.

Mouthguards generally come in three forms:

• Over the counter, ready-made appliances. These are available in drugstores and sporting goods stores, but might not be a comfortable fit as they are pre-formed sizes.
• The “boil-and-bite” option is a mouthguard form placed in hot water. You then bite down to shape it to your mouth and teeth.
• Custom mouthguards can be fabricated just for you through our Chesterton office. These appliances are designed to fit your individual mouth and teeth, so provide a better fit and better protection. They are also usually more durable and more comfortable. If you wear braces, you definitely need a custom mouthguard to prevent an injury to your mouth or braces caused by an ill-fitting appliance.

Whether you play on a team or pursue individual athletic activities, keeping safe as you keep fit is your first priority. We would be happy to discuss your mouthguard options for any sport, any time of year.
