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 Greeley office for a thorough professional cleaning.

Be proactive. If you have any questions, talk to Drs. Kevin and Kami Marr 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.

When you were a kid, your parents may have told you to drink milk to build strong bones and grow tall and strong. Now that you have children of your own, you may hear yourself parroting those instructions you received years ago. Getting enough dairy is essential for young children whose teeth are growing. A child who consumes the recommended daily serving of dairy will develop healthy, strong teeth for the rest of his or her life.

So, which foods are the best in terms of acquiring the right amount of calcium? Milk and other dairy products are excellent sources of calcium. Milk also contains vitamin D, phosphorus, magnesium, and proteins. Magnesium promotes calcium deposits in your enamel, while phosphorus forms a small but important barrier against acidic foods that cause cavities. Vitamin D and protein are used by a child’s body to build bone tissue and maintain dental health.

According to a recent study, the majority of Americans, including children, do not receive enough calcium. In fact, according to the Academy of General Dentistry, only one in five children meets even the minimum standards for calcium consumption. The U.S. Department of Agriculture recommends that children under the age of eight should receive two and a half cups of dairy per day. Children older than eight need three full cups, the same as adult men and women. In addition to milk, eating yogurt is a great way your child can increase his or her dairy consumption. Drinking sugary beverages in place of milk causes cavities and tooth decay.

If your child does not get enough dairy consumption, they run the risk of improper tooth development and other dental health problems. Drs. Kevin and Kami Marr and our team at Marr Family Dentistry encourage you to monitor your child’s dairy consumption to ensure he or she grows healthy teeth to last a lifetime.

April showers bring May flowers, and May flowers bring . . . allergies. If you’re one of the millions of people who suffer from seasonal allergies, you might be suffering some dental side effects as well.

When you have pollen allergies, pollen triggers your body’s immune system to release histamines. Histamines are part of the body’s defense system. They cause the tissues in the nose and sinuses to become inflamed and swollen as they increase blood supply to these areas. They also cause your body to produce more mucus.

Normally, mucus from the sinus cavities drains into the nasal cavity and then down the back of the throat, where it mixes with saliva and is swallowed. We never even notice it. Until it’s allergy season. Unfortunately, our defense mechanisms can have some offensively unpleasant consequences.

• Headache & Facial Pain

Our sinus cavities are small hollow spaces in the bones of the head which are filled with air and, like our nasal cavities, are lined with mucous membranes. It’s these membranes, not surprisingly, which produce mucus. And though we might turn up our noses at this slippery topic, mucus is actually quite helpful for trapping and filtering out unwanted hitchhikers like bacteria, viruses, dust, pollens, and other pollutants in the air we breathe before they reach our lungs.

When histamines are released, normal mucus production increases to filter out those tiny pollen invaders. At the same time, tissue around the nose and sinuses swells up, which can trap mucus inside the sinus cavities. This, in turn, causes increased pressure within the sinuses, and this pressure brings on allergy-related headaches and facial pain.  

• Nasal Congestion & Postnasal Drip

With the occasional runny nose or sneeze, you can blow your nose once or twice and that’s that. During allergy season, greatly increased mucus production might see you spending all day within reaching distance of your box of tissues. But when the tissue in your nose is swollen as well, you now find yourself with nasal congestion.

A stuffy nose means excess mucus has to exit somewhere else, which means this extra, often thicker, mucus all drains into the back of your throat. This is postnasal drip, and it can make you miserable in several different ways. Hoarseness. Coughing during the day. Worse coughing at night. Sore throat. Nausea. Difficulty swallowing.

All these allergy symptoms are uncomfortable enough! But, to add to our discomfort, allergies can lead to uncomfortable oral symptoms as well.

• Tooth Pain

A common result of allergies is tooth pain. How does this happen? It’s because of the way our bodies are designed. The maxillary sinus cavities are directly above the roots of our upper molars.

When sinus cavities are congested and sinus pressure builds up, it also puts pressure on these roots. The result is tooth pain, usually affecting several upper molars at once.

• Dry Mouth

One of the natural responses to a stuffy nose is mouth-breathing—we can’t go without air, after all! But exposing the inside of the mouth to all that air dries out delicate gum and mouth tissues. It also reduces normal saliva flow. This can cause xerostomia, more commonly known as dry mouth.

Because saliva neutralizes acidity in the mouth and washes away bacteria and other germs, lower saliva production means greater risk of cavities, infections, and bad breath. Dry mouth can also cause gum irritation and gingivitis, because less saliva means more harmful bacteria build-up between the gums and the teeth.

• Antihistamines & Your Oral Health

If histamines are the problem, are antihistamines the obvious solution? This is a good question for Drs. Kevin and Kami Marr or your physician. Antihistamines can be very drying—so you might find you’re experiencing dry mouth even when all those other pesky allergy symptoms have disappeared. And, if you already suffer from xerostomia, it’s especially important to get your doctor’s advice before buying over the counter antihistamines.

In allergy season, just like any other time of the year, be sure to hydrate and keep up with brushing and flossing for fresh breath and healthy teeth and gums. Talk to Drs. Kevin and Kami Marr if you have persistent tooth pain, dry mouth, or irritated gums—it’s always best to rule out other causes like infection or decay.

But, if your problems are caused by allergies, you don’t have to wait until the next snowfall to get relief. Talk to your doctor or allergist for ways to reduce or eliminate your symptoms before allergy problems start blooming into dental problems. You’ll breathe easier!

A lot of patients go at their teeth like they were sanding an old floor—that is to say, way too hard! Brushing too hard is probably the most common mistake patients make in their oral care routine, and it can be detrimental to the gums and teeth.

What can brushing too hard cause?

• Receding gums
• Bone loss around teeth
• Loss of teeth
• Tooth sensitivity, especially to hot and cold
• Worn down enamel

Brushing too hard wears away at your gums, which can lead to the neck of the teeth being exposed. This part of the tooth isn't covered by hard enamel like the rest of the tooth and hence the soft inner layer, or dentin, is exposed. Dentin is very sensitive to hot and cold and much more susceptible to bacterial decay. Once the gums recede due to improper brushing, it’s usually irreversible.

How to brush your teeth properly

You know you're supposed to brush your teeth twice a day, so why not do it right? First and foremost, you should only ever brush with a soft bristled brush—not medium or hard—unless directed otherwise by Drs. Kevin and Kami Marr. Unless you have braces or specific oral health issues, brushing twice a day for two minutes is usually plenty.

The main purpose of brushing is to remove plaque from your teeth and gums. Plaque is actually soft and is a buildup of bacteria, saliva, and food debris. You really don't need to brush hard to remove it, just make sure you aim your toothbrush at the gum line (where plaque grows) and brush in small circular motions, never a back-and-forth motion.

It's also wise to hold your toothbrush gently. People tend to brush harder the tighter they hold their toothbrush.
