The Science of Sugar

November 22nd, 2023

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 Dr. Meuselbach have the last word on sugar science.

What Are Dental Sealants?

November 22nd, 2023

You’re constantly playing defense. Your child spends two minutes in the morning and two minutes at night carefully brushing and flossing with a fluoride toothpaste. You make sure sugary and acidic foods are not a major part of your diets. Your child visits our West Chester office for regular exams and cleanings. Really, how can a cavity get past all that?

But even with the best defensive practices, you don’t have a level playing field—literally. The tops of our molars and premolars don’t have the smooth, easy-to-clean surfaces that our other teeth have. If you look at the chewing surfaces, you will notice deep grooves which toothbrush bristles have a much harder time reaching.  

Plaque and food particles can become trapped in these grooves (known as pits and fissures), providing perfect conditions for a cavity to develop. That is why cavities are so common in newly erupted molars. Dental sealants protect these teeth from cavities by providing a barrier which smooths out the surface of the tooth and prevents food and bacteria from reaching the molar’s crevices.

Most sealants are invisible plastic resin coatings which we apply in our West Chester office. Usually the procedure is so quick and easy that no dental anesthetic is required. Each tooth will be examined first. If we find any signs of early decay, we will gently treat that area before beginning.

When the tooth is ready, it will be cleaned and dried. An etching solution will be brushed on to the dry surface to roughen the area a bit so that the sealant will hold to the tooth more effectively. A thin coat of the sealant is then painted on and hardened under a curing light. And that’s it!

Once teeth are sealed, they should be cleaned and flossed just as carefully as before. Regular exams and cleanings are still very important, and we can monitor the condition of the sealant and the sealed teeth. Properly applied, sealants can last from three to five years, or even longer.

Who should consider sealants? Sealants are typically recommended when the permanent molars first erupt. Children’s enamel takes a while to become its strongest, and so these just-erupted teeth are more at risk for cavities. Sometimes Dr. Meuselbach will recommend sealants for primary (baby) teeth if needed. But even adults can benefit—talk to us if you are interested and we will let you know if sealants might be right for you.

Sealants are a simple, safe, and minimally invasive way to prevent cavities. Studies of sealed molars and premolars show a dramatic reduction in cavities compared to untreated teeth. Sealants are one of the most effective ways to defend your teeth or your children’s teeth from tooth decay. And as we’ve all heard—defense wins championships!

Heart Disease and Oral Health

November 15th, 2023

Is there a link between oral health and heart health? This is a question that has been receiving a lot of attention in recent studies. While as yet there is no definitive study that proves oral health has an effect on overall heart health, there is also no definitive proof that oral health doesn’t affect heart health. So, what do we know, and, just as important, what should we do?

What do we know? One clear connection exists between gum disease and endocarditis, a rare, but potentially very serious, infection. When we neglect our gums, they bleed more easily. When gum disease advances, the gums pull away from the teeth. This creates pockets which can harbor more bacteria and plaque, leading to infection and even tooth and bone loss. And this bleeding and infection can be serious not only as a matter of dental health, but for your heart as well.

Endocarditis is an infection of the inner lining of the heart and the heart valves. When bacteria from other parts of the body, including your mouth, make their way into the blood stream, they can attach themselves to damaged areas of the heart. The resulting infection can become very serious, very quickly. If you have damaged heart valves or artificial valves, have an artificial heart, or have any type of heart defect, it is especially important to prevent gum disease from developing. Regular dental care will help prevent bleeding gums and infections, and reduce the danger of oral bacteria entering the bloodstream. Always let us know if you have any issues with heart health, and we will tailor our treatment for all of your procedures accordingly.

What else might link oral health and heart disease? Because an increased risk of heart disease has been found in patients with moderate or severe gum disease, there has been much speculation as to a possible cause-and-effect connection. For example, the plaque inside arteries which leads to heart attacks has been found to contain certain strains of periodontal bacteria. Other studies have searched for a causal relationship between inflammation resulting from gum disease and inflammation leading to heart disease.  The body’s immune response to periodontitis and its potential consequences for heart health have also been examined. So far, there has been no clear evidence that treating gum disease prevents the occurrence or recurrence of heart disease.

So what should we do? This is the easy part. Keeping your gums and teeth healthy will increase your quality of life in immeasurable ways. And it’s not difficult! Regular brushing, flossing, and dental exams and cleanings at our West Chester office are the key to lasting oral health. If this also keeps your heart healthy, that’s the best possible side effect.

Treating Gum Disease with Antibiotics

November 15th, 2023

Why does gum disease develop? Our mouths are home to bacteria, which form a film called plaque. Plaque sticks to the surfaces of our teeth, at the gumline, and can even grow below the gumline. And this bacterial growth leads to inflammation and gum disease.

When the disease progresses, the gums gradually pull away from the teeth leaving pockets which can be home to infection. Toxins can attack the bone structures and connective tissue, which support our teeth. Left untreated, periodontal disease can lead to serious infection and even tooth loss.

Because we are dealing with bacteria, it makes sense that antibiotics are one way to combat gum disease. Depending on the condition of your gums, we might suggest one of the following treatments:

  • Mouthwashes—there are mouthwashes available with a prescription that are stronger than over-the-counter antibiotic formulas, and can be used after brushing and flossing.
  • Topical Ointments—These ointments or gels are applied directly to the gums, most often used for mild forms of the disease.
  • Time-release Treatments—If there is severe inflammation in a pocket, we might place a biodegradable powder, chip, or gel containing antibiotics directly in the affected area. These minute methods release antibiotics over a period of time as they dissolve.
  • Pills and Capsules—For more serious periodontal disease, you could be prescribed an oral antibiotic. Take in pill or capsule form as recommended, and always finish the entire prescription.

Talk to Dr. Meuselbach at our West Chester office before beginning a course of antibiotics. It’s important to know if you have any allergies to medications, what to look for if you might have an allergy you didn’t know about, if you are pregnant or breast-feeding, or if you have any health concerns that would prohibit antibiotic use. Talk to us about possible side effects and how to use the medication most successfully. With proper treatment, we can treat gum disease as quickly and effectively as possible, and provide advice on maintaining a periodontal routine that will keep your gums and teeth healthy for years to come.
