The Science of Sugar

March 27th, 2024

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. Ashmita Shetty have the last word on sugar science.

What are dental sealants and how do they work?

March 20th, 2024

A dental sealant is a liquid that is applied to the teeth. The sealant hardens and provides a protective coating that is designed to reduce cavities and create a smoother tooth surface. Dental sealants are clear or white; they do not take away from the appearance of teeth. You can think about this treatment as being similar to varnish that protects a wood floor.

Sealants are not the same as fluoride treatments. The application is similar, but sealants are a semi-permanent protective coating. Dr. Ashmita Shetty and our staff recommend that sealant applications for children begin soon after molars erupt, first molars around the age of six, and second molars around the age of 12.

Simple Application

Having sealants applied is not uncomfortable at all. First, your child's teeth will be cleaned and dried. A gel is applied, which helps the sealant adhere to the tooth, and then is rinsed away. Your child's teeth are dried again and the sealant is applied. A few seconds of exposure to a light source may be used to cure the sealant and make it semi-permanent. Sealants should last for a long time, normally between five and ten years.

Sealant Benefits

The coating on the surface of your child's teeth reduces the amount of acid contact. Normal acids in foods that are consumed can eat away at the surface of teeth. Bacteria also react to plaque formation and create more acid in the mouth. These small pits or weakened areas are prone to caries or cavity formation. Preventing cavities is a much better choice than drilling and filling damaged teeth.

A sealant also helps to smooth the chewing surfaces of your childn't teeth. The smoother surface is not as likely to retain small particles of food and bacteria. Your child's mouth stays cleaner and food is not left behind to form acids. The protective application can also be used on other teeth that have a rough surface, to protect the grooves or pits from decay.

After the sealant is applied, your child still needs to take proper care of his or her teeth. Regular brushing and flossing is required. Dr. Ashmita Shetty may recommend fluoride treatments to strengthen and protect your child's teeth further.

If you have any concerns about sealants, please discuss them with during your child's next appointment at Berryessa Dental Spa. We want your little one's teeth to stay healthy for life.

St. Patrick's Day

March 13th, 2024

On March 17, everyone has a little Irish in them. St. Patrick’s Day is a joyous celebration of Irish heritage. The holiday originated as a commemoration of Saint Patrick, who brought Christianity to Ireland. The saint arrived in Ireland in 432 and earned the reputation of a champion of Irish Christianity. March 17th, the day of St. Patrick’s death, has been commemorated by the Irish for over 1,000 years. St. Patrick’s Day is still observed as a religious feast day by several Christian denominations, but it is better known in the public imagination as a rich celebration of Irish culture.

St. Patrick’s Day has been an official public holiday in Ireland since 1903. Each year, the Irish celebrate with a several-day festival that includes theater performances, music, fireworks, and festive parades. The celebration is also a public holiday in Northern Ireland, Montserrat, and Newfoundland and Labrador. In other parts of the world with heavy Irish populations, it is an unofficial celebration of Irish heritage. Parts of Great Britain, Canada, Argentina, South Korea, Switzerland, New Zealand, the United States, and Australia commemorate the holiday each year. Typical celebrations in these countries include drinking green beer, wearing green, eating traditional Irish foods, parades, and shamrock decorations.

Many people, Irish and non-Irish alike, take part in the “wearing of the green” on St. Patrick’s Day. In fact, the color originally associated with Saint Patrick was blue. His use of shamrocks to explain the Holy Trinity to the Irish made the green clover emblematic of the holiday, leading to the traditional green attire worn by thousands on St. Patrick’s Day. Other little-known facts about St. Patrick’s Day include the following:

  • Each year, the United States and Ireland face off in a rugby competition called the “St. Patrick’s Day Test.”
  • Montreal celebrates the holiday with an annual parade, which has been held each year since 1824. The Montreal city flag even features a shamrock in its corner, as a nod to its Irish heritage.
  • The Guinness World Records named St. Patrick’s Day the “Friendliest Day of the Year.”
  • Along with Valentine’s Day, St. Patrick’s Day is one of the most widely celebrated saint’s day in the world.

No matter your cultural heritage, St. Patrick’s Day is a great time to let loose and celebrate your inner Irish-ness! Don your greenest attire and exclaim “Erin go Bragh!” (Ireland forever!) to everyone you meet. From Dr. Ashmita Shetty - have a great St. Paddy’s day!

What are dental sealants, who should get them, and how long do they last?

March 6th, 2024

Dental sealants are an excellent way to protect children’s teeth from tooth decay by coating them with a thin plastic material. Their teeth look and feel like normal, but they are protected from plaque build-up and decay early on. Dr. Ashmita Shetty and our staff recommend sealants as a preventive measure for children before any decay appears on their teeth.

Who should get dental sealants?

Dental sealants are intended for young children as soon as their first teeth come in. Decay is most common in the molars, so taking your child to Berryessa Dental Spa for sealants right when you see the molars grow in gives your child the best chance to fight tooth decay.

A child’s first set of permanent molars grow in between ages five and seven, while the second permanent molars come in between 11 and 14 years of age. Some teens and adults who don’t have tooth decay may get sealants as well, but it is less common.

How long do dental sealants last?

Once the sealant has been placed on the teeth, it lasts up to ten years. Expect to have Dr. Ashmita Shetty check the sealant at every visit to our San Jose office, which should be twice a year. We will look at the sealant and determine if it needs to be replaced.

What is the process of getting sealants?

Applying sealants is a simple, pain-free procedure that is done quickly at Berryessa Dental Spa. There is absolutely no effect on the tooth structure from sealants.

For starters, the teeth are cleaned carefully, then dried with an absorbent material. A mild acid solution is applied to them to roughen them slightly. This is done so the sealant can bond properly to the teeth. Then the teeth are rinsed and dried, and the sealant material is painted on and dried with a special light.

Molars are susceptible to decay early on, which is why sealants are an important treatment to get for your children’s first set of teeth.
