Plaque is a sticky subject! It sticks to the enamel of our teeth above and below the gum line, and it collects around fillings, braces, and other dental work. 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 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. If you have braces or oral issues that make brushing more often advisable, ask us 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.

• 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.

• Tip: If you have trouble removing plaque 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 us for a recommendation the next time you’re in for a cleaning.

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.

• Tip: Do you floss before or after you brush? While both methods have benefits, many dentists and periodontists suggest flossing first. But really, if you are flossing daily, no matter what the order, you’re doing it right!

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. We can not only remove any plaque that’s been overlooked, we can eliminate the tartar which can cause serious gum disease.  And, of course, we can give you all the information you need to keep your teeth their cleanest.

• Final Tip: It’s important to schedule cleaning appointments at our Dartmouth, MA office on a regular basis to help prevent tooth decay and gum disease. Ask us for phone, text, or email reminders when it’s time for your next cleaning.

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, every time you brush and floss, every time you see Dr. Ghenta for a checkup and a cleaning. 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!

Should a quick bite between meals make us feel guilty? Or worse, make our teeth suffer a greater risk of cavities? Let’s avoid both those possibilities! We have several tooth-healthy snacking strategies designed to help you keep your enamel cavity-free while preventing snacker’s remorse.

But first, a word or two about why we may find snacking unappetizing.

• Please, Don’t Feed the Bacteria!

The bacteria in plaque feed on sugars and leave acidic waste products behind. These acids attack enamel, dissolving the calcium and phosphorus minerals that keep it strong. Weakened enamel leaves teeth vulnerable to decay. That’s why Dr. Ghenta and our Dartmouth, MA team recommend avoiding a steady diet of sugary treats.

Even if you’re not reaching for a soda, or grabbing a candy bar, many snack foods are filled with added sugars. Check the nutritional labels before you indulge to avoid sugar surprises.

• Off Balance?

Bacteria plus sugar equals more acidic conditions in the mouth. This change in the oral pH balance also reduces our natural defenses against cavity-causing acids.

A well-balanced oral environment depends on saliva to keep acids in check. Saliva washes away lingering food particles after meals, and it neutralizes acidic conditions in the mouth over the course of the day.

How does snacking interfere? Immediately after eating or drinking, acids in saliva increase. It takes about 20 minutes for saliva’s neutralizing process to begin. When we snack throughout the day, saliva doesn’t have a chance to reduce acids as long or as effectively.

• Staying Power

Sticky and chewy snacks tend to stick to the tops of molars and between the teeth. This gives bacteria more fuel and more time to attack tooth enamel. It’s not just candies that are the culprits here. Chips, bread, pizza crusts, pastries—these simple carbs stick to teeth and break down easily into sugars.

But we promised some *positive* strategic snacking ideas. Here are some ways to make sure that snacking doesn’t put you at a much greater risk for cavities.

• Be Choosy

Avoid processed treats that are high in added sugars. If you’re craving something sweet, fresh fruits provide sweetness with vitamins included.

Crispy fruits such as apples and Bosc pears, as well as vegetables like celery and carrots, provide gentle scrubbing action to help clean teeth between brushings.

Snacking on cheese helps neutralize acids, and other dairy products are high in calcium and phosphorus, helping rebuild the minerals that acids leach out of enamel.

Eat whole grain breads, pastas, and pastries. They offer more nutrients, and don’t break down into sugars as easily.

Finally, when it’s time to indulge in a sugar-rich treat, save it for a meal. There’s a better chance that other foods will balance the acids created by sugar, and you’ll be getting the most out of saliva’s neutralizing abilities. Speaking of which,

• Stay Neutral

When you’re craving something flavorful without giving bacteria more fuel for acid production, consider sugar-free gum. Sugar-free gum saves you from adding sugar to your diet, and it increases saliva production as you chew. If we give you the all-clear, chewing a piece or two of gum during the day can help curb your sugar cravings and protect your enamel.

Thirsty? Drink water instead of sodas or energy drinks with your snacks. Water washes away food particles, cuts down on acidity, and provides fluoride to strengthen and protect teeth.

• To Brush or Not to Brush?

It’s always a good idea to brush after eating. But since eating sugary or acidic foods can leave enamel vulnerable to toothbrush abrasion, many dentists recommend waiting 30 minutes after you snack before brushing. Ask Dr. Ghenta what’s best for your teeth.

If you can’t brush, rinse with water after eating or drinking.

If you wear braces or aligners, be sure to check with Dr. Ghenta about snacking, gum, best times to brush, and any other diet questions.

Talk to Dr. Ghenta about your snacking habits. Learning when and how to snack is as important as deciding what to snack on. Finding the perfect balance means you can enjoy a mid-day energy boost without guilt—and without risking tooth decay!

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 Dr. Ghenta 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 Dr. Ghenta 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 strong, healthy smile is built on a strong, healthy foundation. Let’s take a moment to explore just what creates that foundation—your roots.

The Root of the Matter

The visible part of your tooth is called the crown. And while we spent the great majority of our time thinking about what goes on above the gum line—brushing, flossing, whitening, sealing, preventing cavities—the roots, the parts of the teeth below the surface, are also essential to our dental health.

• What’s inside the root?

The inside of each tooth holds pulp, which is living tissue made of nerves, blood vessels, and connective tissue. The nerves in the pulp allow us to feel pain when a tooth is damaged, decayed, or infected. Tiny blood vessels provide oxygen and nutrients to the cells.

The inside of each root also contains pulp, located in one or more root canals. These canals are small tunnels that travel from the pulp chamber to the tip of each root. Nerves and blood vessels connect pulp tissue to the nervous and circulatory systems in the body, entering and exiting the tooth from very small openings in the root tip.

• What’s outside the root?

On the outside, while roots look like crowns, they’re covered with a different protective surface. Roots are covered by cementum rather than enamel. This is a hard tissue, but not as hard as enamel. But cementum has another advantage—it not only helps protect our teeth, it helps them stay anchored in our jaws. (More on this below.)

• How many roots are we talking about?

The number varies, not just depending on the tooth, but depending on the individual. Most adults have 32 adult teeth: eight incisors, four canines, eight premolars, eight molars, and four wisdom teeth, or third molars. Because the number of wisdom teeth can range from four to zero, though, that total can be smaller.

Rooted to the Spot

The reason that you can rely on your teeth for a lifetime of chewing, biting, and grinding food is the fact that they’re so securely anchored in the jaw.

• Alveolar bone in the jaw contains a socket for each tooth.

• A thin layer of connective tissue called the periodontal ligament lines the socket and surrounds each root. It’s filled with fibers that attach to the root’s cementum covering and to the alveolar bone, holding the tooth securely in place.
• The periodontal ligament not only anchors the tooth, it cushions it from the daily pressure of biting and chewing.
• Finally, the gums surround the teeth and bone, protecting them from bacteria and plaque.

Even though this design is very secure, there are situations where the root becomes vulnerable. In that case, you should see Dr. Ghenta at our Dartmouth, MA office right away. Our goal is for you to keep your teeth healthy and strong, and for a lifetime!
