Educational and Entertaining Enamel Experiments

March 27th, 2024

Let’s talk about the science of our teeth for a moment. Our enamel has a very high mineral content, making it extremely strong.  In fact, enamel just happens to be the hardest substance in our bodies.  But, unfortunately, it is not indestructible! Certain foods we eat can actually damage the surface of our teeth. Some simple and entertaining experiments can show children how our teeth can be affected by things we eat and drink, and how we can help protect them.

If you have a science-minded student at home, there are many activities you can do together, using educational websites, common household products and lots and lots of eggs. (Why eggs? Eggshells are a great substitute for teeth in these experiments. Not only are they various shades of white--like our own teeth, they are also calcium-rich—like our own teeth.) You can find any number of experiments using uncooked eggs, hardboiled eggs, whole shells with the contents blown out, or eggshells alone, so you can find just the right activity for whichever egg treatment works best for you.

Examine Enamel Erosion

One of the ways we protect our teeth is with healthy eating. The bacteria in plaque use the sugars and starches in our foods to produce acids. These acids are the substances that break down the minerals in our enamel and leave the enamel weaker. Weaker enamel is more easily attacked by bacteria and acids, which leads to cavities.

With eggs or eggshells and some carefully selected food products, you can see just how acidity affects teeth. Different websites suggest a variety of acidic liquids to dunk your eggs in, such as vinegar, soda, or citrus juices, so it’s easy to find an experiment that works with your pantry. Always use a plain water sample when you submerge eggs or shells to act as a control to measure differences against. How do the egg shells soaked in acidic liquids differ from those in plain water? It’s also fun to add simple sugar water as a test liquid to see what happens. Is it sugar or acid that causes more damage? And why might that be?

The Fluoride Fix

Fluoride is well known as a mineral that protects the structure of our teeth and helps prevent cavities. And there are actually experiments out there to test the protection fluoride provides using your egg stand-ins.

In some experiments, a hardboiled egg is coated with fluoride toothpaste or rinse for a specific amount of time and then dunked into vinegar. An untreated egg also gets a vinegar bath. You are asked to observe what is happening to each egg as it sits in its vinegar bath—are there bubbles on one egg and not the other? What do the bubbles mean? Other experiments require longer exposure to fluoride and then to vinegar—what happens to the shells of the treated and untreated eggs? What could this mean for our teeth?

Staining Studies

Our diet can do more than help create cavities. Enamel is very strong, but it is not stain-proof! Dark colored foods and drinks can make our teeth appear darker or more yellow. (And teeth that have suffered enamel erosion can pick up stains more easily.) How does food affect the brightness of our smiles?

If this question interests you, find experiments that use favorite beverages as a soak for your eggs. Choose liquids with a range of color, such as coffee, soda, and apple juice. Or choose an experiment that uses different varieties of soft drinks. Will foods the same color cause the same amount of discoloration in your egg volunteers? Do you want shorter or longer soaks in each liquid? Do you want to make use of a recycled toothbrush to see if brushing that discolored shell makes a difference? With toothpaste or without?

Even though these activities are designed for older children, they still require adult supervision. You can find detailed instructions for any of these experiments at many science and educational sites online. With some household supplies, plenty of extra cups, and a quantity of eggs, you and your child can demonstrate some of the basic effects our food choices have on the health and appearance of our teeth. It’s a wonderful way to promote healthy eating and brushing habits, scientific curiosity, and shared experiences!

Don’t forget to let Dr. Henricksen know how your experiments turned out the next time you visit our Chehalis office!

What is biofilm?

March 20th, 2024

Biofilm, the protective housing for bacteria, is a hot topic in the medical and dental fields. Routinely taking an antibiotic for a bacterial infection has become more complicated because of biofilm. Bacterial infections may become resistant to antibiotics in part because the biofilm allows for communication among the bacteria, allowing the infection to be sustained.

You’re probably wondering, Dr. Henricksen , what does this have to do with teeth? Since we’re dental professionals, we can tell you why it’s important and what you should know! There is biofilm in your mouth; healthy biofilm and diseased biofilm. Both are made of the same general compounds, but when combined with certain amino acids and cellular chemicals, the diseased biofilm conquers and destroys.

Periodontal disease, otherwise known as gum disease or pyorrhea, is a biofilm disease. If you are undergoing treatment for gum disease and you do not continue with the treatment plan the disease will progress and/or spread due to the biofilm.

There are several ways to treat diseased biofilm. But remember, antibiotics cannot touch the bacterial infection if the biofilm is established.

When your exam is complete, the Ultrasonic or Piezo Scaler should be used. This method of spraying water disturbs the biofilm and provides an opportunity to treat the infection causing bacteria.

Remember, we all need healthy biofilm. Just as your skin protects your body, biofilm housing good bacteria protects your body. The bacteria in the biofilm replicate every twenty minutes. If your body has healthy bacteria, low levels of hydrogen peroxide are produced by the biofilm, preventing harmful bacteria from residing. Harmful bacteria do not like oxygen.

At your exam, we will take measurements around your teeth checking for “pockets”. The higher the number, the deeper the pocket giving more room for harmful bacteria where there is no oxygen. Ask what your numbers are and be involved in restoring your healthy biofilm.

St. Patrick's Day: Celtic pride, green shamrocks, and lucky charms!

March 13th, 2024

“St. Patrick's Day is an enchanted time -- a day to begin transforming winter's dreams into summer's magic.” Adrienne Cook

Lucky green shamrocks, leprechauns, and pots of gold – it must be St. Patrick’s Day! If you’re not Irish, how do you go about celebrating St. Patrick’s Day? It’s easy: You just put on one of those tall leprechauns hats, dress in green from head to toe, and wear one of those carefree pins that say “Kiss Me, I’m Irish”. On St. Patrick’s Day, everyone is Irish, and that is the universal beauty of the holiday. Celtic pride does not discriminate.

Wondering what our team at Henricksen Family Dental is doing to celebrate March 17th? Well, we’ve thought about doing everything from handing out lucky gold coins (you know, the fake ones that are made of chocolate) to shamrock stickers. Maybe we’ll even give away green toothbrushes and floss! You’ll never know unless you come in to see Dr. Henricksen !

All kidding aside, St. Patrick’s Day is an important cultural and religious holiday. There are lavish parades and church services across Ireland on March 17th. Over time, however, the holiday has developed into a day to observe Irish culture in general. In places like England and the United States, where there is a large Irish Diaspora, the holiday has greater significance than other countries. From the streets of Boston to St. Patrick’s Cathedral in New York, it is a day of celebration, and many Americans of Irish descent will cook up a traditional meal of corned beef and cabbage.

So, to all of you with Irish ancestry, and to all of you who have decided to be Irish for the day, our office wishes you a Happy St. Patrick’s Day. Good luck looking for a pot of leprechaun gold, which is said to exist at the end of the rainbow. However, keep away from those sugary Lucky Charms; sweet cereals might taste good, but your kids’ teeth might not be feeling too lucky if they eat it for breakfast every day. Have a great St. Paddy’s Day!

March is National Nutrition Month!

March 6th, 2024

While you don’t have to wait to start eating right, March is the month the Academy of Nutrition and Dietetics asks everyone to pay special attention to what goes into our bodies. The Academy has designated the month of March for focusing the public’s awareness on what they eat.

What Not to Eat

The academy points out that the foods you eat have a direct effect on the health of your teeth and specifically on tooth decay. Bacteria rely on carbohydrates to thrive. That is why Dr. Henricksen and our team at Henricksen Family Dental tell our patients to cut back on both candy and sweets. They consist of simple sugars that feed the bacteria in your mouth and enhance tooth decay.

It’s the hidden sugars that will cost you, though. Get in the habit of reading labels on food and looking for products with added sugar. This includes ingredients that end with the suffix “ose.” When it comes to nutrition, these foods offer little value beyond satisfying that sweet tooth.

What You Should Eat

Turn to foods that not only taste good but are good for your teeth too. Dairy products, for example, provide the body with nutritional items that support tooth enamel. Foods high in protein feature phosphorus, a nutrient critical to oral health.

You can’t really go wrong by adding color to your diet, either. Fruits and vegetables make for a colorful plate and a healthy meal. Use some caution with acidic fruits like oranges or even tomatoes, because the acid can erode tooth enamel. It is better to include these foods in a meal instead of eating them by themselves.

Remember, good nutrition is something you should worry about all year long, not just when celebrating National Nutrition Month. March just serves as a fun reminder that eating right is a proactive step in managing your dental health.
