Some languages have many different words for love. Some have many different words for snow. One language even has different words for a tasty layered sandwich. Is that a hoagie or a hero you’re having? A sub? Grinder? Po’boy?

“Sugar,” though, is a single word which has taken on many meanings, from casual endearment to monosaccharide molecule. Today, we’re examining scientific definitions, with a short and sweet look at the science of sugar.

Chemistry

First, let’s get basic—all the way down to the molecular level.

Carbohydrates, fats, and proteins are the three essential macronutrients which keep our bodies running. Sugars are molecules made of carbon, hydrogen, and oxygen atoms, and all carbohydrates are made of these sugar molecules, from single unit structures to very complicated chains.

Sugars called monosaccharides are the most basic of the carbohydrates. “Monosaccharide” comes from the Greek words for “single” and “sugar,” and monosaccharides are the sugars we mean when we talk about “simple sugars.” Why are they simple? Because a monosaccharide is a single molecule which can’t be broken down into smaller carbohydrates.

While there are several types of monosaccharides, the three major simple sugars are:

• Fructose—the sugar we get from fruit.
• Galactose—the sugar found in milk.
• Glucose—the sugar our bodies use the most. It’s found in plants, and also produced when our bodies break down other carbs. Fun fact—this is the only sugar essential for brain cell function.

When two monosaccharide molecules join together, they form a disaccharide (not surprisingly, from the Greek for “two sugars”). Again, there are quite a few disaccharides, but we tend to concentrate on three in our diets:

• Lactose (glucose + galactose)—found only in milk and dairy products.
• Maltose (glucose + glucose)—the sugar chiefly produced by grains.
• Sucrose (glucose + fructose)—produced in plants. These plants include sugar cane and sugar beets, from which we get our refined table sugars.

The reason sugar molecules are so important is because of how our bodies use them.

Biology

Our bodies use the glucose in carbs for energy. As foods break down, first through digestion and then in the cells, the chemical bonds which hold glucose molecules together break as well. This action releases energy, and this energy fuels all our bodily functions.

But even though we need carbohydrates to keep our bodies going, and even though sugars are the easiest carbs to use for energy, there’s a reason no one recommends a diet filled with extra sugar.

Our bodies get all the sugar they need from the natural sugar in the foods we eat. Natural sugars are found in fruits, dairy products, even some vegetables and grains. Along with that sugar come vitamins, minerals, antioxidants, fiber, and/or protein.

Extra sugars added during baking or mixing or processing for flavor and sweetness provide none of these nutrients. These sugars are known as “added sugars,” and have more serious consequences than just empty calories.

Once we have the sugars we require, there’s no need for more. Extra sugars are stored in liver, muscle, and fat cells for later use. When we eat too much sugar, this carefully balanced system is upset, with negative effects for, among other things, weight, blood sugar, insulin levels—and our dental health.

Nutrition and Dental Health

You know that a sugar-filled diet often means a cavity-filled checkup. Why? Because it’s not just our bodies that break down sugar for fuel.

The oral bacteria in plaque also need sugars for food, which they use to make acids. An acidic environment in the mouth weakens and dissolves the minerals which keep tooth enamel strong. And these weak spots are vulnerable to decay. A steady diet of sugar-filled foods means that your enamel is constantly under acid attack.

Cutting down on added sugars is one of the easiest and best ways to cut down on added cavities. Reading recipes, checking out labels, learning to recognize added sugars—this is nutritional research which has sweet results.

How to recognize added sugars? Here’s where language gives us plenty of words to fill our linguistic sugar bowl. Whether the ingredients are called agave nectar, honey, molasses, syrups, treacle, or table sugar, they’re really just sugar. More specifically, they’re all sugars made up of glucose and fructose, with at best a trace amount of vitamins and minerals—and usually not even a trace!

To make our lives easier, labels on food packaging now let us know exactly how much of the sugar in any product is “added sugar.” You expect to find a high percentage of sugar on dessert labels, but you might be surprised to read how much sugar is added to foods like energy drinks, sports drinks, flavored yogurts, cereals, spaghetti sauce, and many more of the items in your grocery cart. Spend an extra minute examining the label, and save yourself many empty calories.

Monosaccharides, disaccharides, glucose, fructose, maltose, agave syrup, treacle, and on and on—so many words for so many kinds of sugar. When it comes to dental health, let Drs. Sidney and Jacob Kelly have the last word on sugar science. During your next visit to our Roseville, CA office, talk to us about reducing unnecessary sugars in your diet for a future filled with the sweetest of healthy smiles.

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. Sidney and Jacob Kelly 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. Sidney and Jacob Kelly 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!

Most of us know that unpleasant feeling. You’re happily enjoying an icy milkshake with lunch or having a piping hot cappuccino break, and suddenly an innocent binge turns to cringe—your tooth sensitivity has crossed another item off the menu. If heat, cold, even the act of brushing cause you tooth discomfort, we have solutions for you. Let’s look at some of the common reasons for tooth sensitivity and how to prevent it.

• Bad Brushing Habits

There can be too much of a good thing! Aggressive brushing, especially with firm toothbrushes, can damage enamel. When the dentin underneath is exposed, heat and cold can reach the sensitive inner tooth and trigger discomfort.

Go easy on yourself: Switch to a soft bristled or electric toothbrush and brush thoroughly but gently. It’s often suggested that we massage rather than scrub. We can also recommend toothpastes that can help reduce sensitivity.

• Gum Disease

As gum disease progresses, the gums start to pull away from the teeth and expose their roots. Even though the roots are protected by cementum, a covering a lot like enamel, they are more sensitive to heat and cold. And if you are an aggressive brusher, the cementum is more easily damaged than enamel, leaving the sensitive roots even less protected.

Prevention is the answer: Brushing and flossing help prevent gum disease, as do your regular exams and cleanings. If you are suffering from more advanced gum disease (periodontitis), Drs. Sidney and Jacob Kelly can suggest advanced treatment to protect your roots, such as deep cleanings and gum grafts. Don’t let periodontitis go untreated, as it can lead to infection and even tooth loss.

• Your Diet

If your enamel is already compromised, sugary foods and acidic foods can cause tooth discomfort.

Be patient: Until your sensitivity problem is under control, avoiding these types of foods will help. On the other hand, sugary and acidic foods aren’t the ideal dental diet, so cutting back is not a bad idea.

• Your Dental Products

Mouthwash, whitening toothpastes and home whitening products contain substances such as alcohol or bleaching agents that can cause sensitivity in some users.

Make some changes to your shopping list: Choose products without alcohol or whiteners. Talk to us about gentler alternatives for mouthwashes and whitening.

• Tooth Injuries

If you have a cavity, a broken filling, a cracked tooth, or some other injury to the tooth, sensitivity can be a warning sign.

Take care of yourself: Call our Roseville, CA office immediately if you have prolonged sensitivity or any other painful symptom. Repairing and restoring your damaged tooth should eliminate this discomfort. And, while it is often common to experience some degree of sensitivity after dental work, if this doesn’t clear up within a short time, let us know.

• Teeth Grinding

Because grinding also wears away enamel, tooth grinders often suffer from sensitive teeth.

Protect yourself: We can fit you for a custom nightguard that will eliminate the nightly stress on your enamel. It can also help the tooth and jaw pain caused by grinding.

Talk to us about any sensitivity you have been experiencing, especially if it has been going on for a while or is causing you real discomfort. We will explore the possible reasons for your tooth sensitivity and help you find solutions. After all, you should feel free to enjoy any item on the menu, in the very best of dental health.

Baby teeth are very important to your child’s present and future dental health, so we want to help you keep your child free from cavities and gum disease even before those permanent teeth erupt. That’s why we recommend professional cleanings at our Roseville, CA office—to keep plaque and tartar from damaging little teeth and gums.

But a dental cleaning might be a bit stressful for young children, especially when they’re not used to the steps, the sounds, and the sensations of the cleaning process.

So, just as we strive to make every examination and visit a positive experience for your child, we do our best to make their cleanings a happy, stress-free time. How do we do this? With your help!

• Preparation

A happy experience begins even before your child arrives in the office. If you are relaxed and positive before an appointment, you’ll help your child feel relaxed and positive, too.

Explaining what goes on during a cleaning even before your visit will help your child feel more comfortable when unfamiliar tools like dental mirrors, scalers, and polishing brushes are used. You can talk about your own experience, read a book together, watch a video, or find online resources to help your child understand what will happen during your visit, and why cleanings are so important for happy, healthy teeth.

Sometimes children benefit from a form of mild, conscious sedation (such as nitrous oxide) when they have special health needs or dental anxiety. If you feel this is an option we should discuss, please talk to us in advance and we’ll answer any of your questions.

• Pre-Cleaning Examination

After being made welcome in the office and settled comfortably in the dental chair, we’ll examine your child’s teeth and gums for any signs of plaque and tartar.  A small, handled mirror is used to check out hard-to-see places behind the teeth and in the back of the mouth. Gum health is also important, and your child’s gums will be examined for any signs of gingivitis, or mild gum disease.

Plaque and tartar cause cavities and gum disease, even for young children. Finding any trouble spots will let us know where to concentrate on cleaning, and where you can help your child to brush more effectively.

• Removing Plaque and Tartar

No matter how well a child (or an adult!) brushes and flosses, plaque can build up in some hard-to-reach spots, especially between the teeth and along the gumline. And if plaque isn’t removed within a few days, it starts hardening into tartar—and tartar can’t be brushed away.

That’s why removing tartar is a job for a dental professional. Using a special tool called a scaler, we gently scrape built-up plaque and tartar off tooth enamel (especially where it tends to accumulate behind and between teeth) and near the gumline. Sometimes an ultrasonic scaler can be used to dislodge tartar with sound waves.

Scalers can make a scraping noise and cause some pressure, and ultrasonic scalers use a stream of water as they clean. We’re happy to explain, in an age-appropriate way, why tools make these noises and how they work to clean little teeth.

• Polishing & Flossing

After the plaque and tartar are removed, your child’s teeth will be polished with a power brush and a special gritty toothpaste. This is usually a bit noisy as well. A careful flossing and a final rinse will wash away any leftover particles or paste.

Once the teeth are cleaned, you may choose to have a fluoride treatment or a dental sealant applied to your child’s teeth.

• After a Cleaning

Your praise and encouragement are always welcome! Giving children praise for helping keep those little teeth clean, shiny, and healthy makes them partners in the process.

How do we clean your child’s teeth? Gently. Thoroughly. Expertly. We want to make sure each cleaning is just one of the many positive dental experiences your child will have in our office. Help us make your child’s cleaning appointment stress-free with positive preparation and reinforcement, and together we’ll start your child on the path to a lifetime of shining smiles and proactive dental care!
