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!

Bottled Water: Friend or Foe?

March 20th, 2024

Some people choose bottled water over tap because they think it’s cleaner. Some do it out of convenience: It’s easy to grab a bottle of water to take with you for the day as you run out the door or hop in your car.

Whatever the reason, bottled water has been coming in ahead of tap water for the last couple of years. What many people may not know is that choosing bottled water over tap can actually be detrimental to your dental health.

Most brands of bottled water fail to include a vital ingredient: fluoride. Fluoride plays an important role in helping maintain good oral health because it helps strengthen our teeth. Stronger teeth mean a lower chance of tooth decay, and who doesn’t want that?

When we choose bottled water over tap water, we deprive our pearly whites of something they might very well need.

The good news is that the American Dental Association has endorsed both community water fluoridation and products that contain fluoride as a safe way to prevent tooth decay. If bottled water happens to be the preference for you or your family, you don’t necessarily have to force everyone to start drinking tap water.

Just check the label and make sure the brand you purchase contains fluoride.

It’s essential to remember that switching up the water you drink isn’t going to put you on the fast track to perfect teeth, though. Flossing and brushing three times a day is vital!

If you have any questions about fluoride or your dental health, don’t hesitate to ask Dr. Kelly Peterson at our Marysville, WA office!

In the Pink

March 13th, 2024

Our gums cover and protect the sensitive roots of our teeth and the bone around them. While we often think of gum tissue as a rosy shade of pink, that’s not a hard and fast rule. Just as skin tones vary, gum color can vary from person to person.

Healthy gums can range from light pink to darker pink to hues of brown or black. Because your gums are a good indicator of your oral health, what’s important isn’t your normal gum color, it’s noticing any changes in your normal gum color. These changes could be symptomatic of several different dental and medical conditions.

Pale Gums

  • Anemia

If the overall appearance of your gums is paler than usual, anemia is a prime suspect. Anemia is a common condition caused by a low red blood cell count. Hemoglobin in red blood cells delivers the oxygen our tissues need to function properly, and without enough, we suffer symptoms like fatigue, weakness, pallor, faintness, and rapid heartbeat.

Anemia can be caused by an underlying medical condition, or can develop because of other issues, such as iron or vitamin deficiencies, pregnancy, ulcers, certain medications, or heavy menstrual periods. If you have any of the symptoms of anemia, seeing your doctor for a blood test is a good idea.

  • Teeth Whitening

Occasionally, gums can also lighten up after a tooth whitening procedure. This is due to tissue irritation caused by the bleaching chemicals. Usually this condition is very temporary.

Ask Dr. Kelly Peterson for advice if you experience irritation after home treatments. Having your teeth whitened by a dental professional is one way to make sure your gums get the best protection possible during the process.

Red Gums

  • Inflammation

Red gums are a common symptom of gingivitis (early gum disease). Plaque and tartar irritate your gums, and gum tissue reacts to this irritation by becoming inflamed. Left untreated, gingivitis becomes periodontitis (serious gum disease), which can destroy the bone around the tooth and lead to tooth loss.

If you notice signs of gingivitis—redness, swelling, bleeding, bad breath—talk to Dr. Kelly Peterson. Often, gingivitis is easily remedied in the early stages by better attention to dental hygiene. Brushing for two minutes at least twice each day and flossing at least once a day are a good base line for keeping gum disease at bay.

  • Infection

Redness can also be caused by infection. If you’re experiencing redness, pain, loose teeth, swelling, pus, or fever, it’s important to see Dr. Kelly Peterson as soon as possible in case you have an abscess or infected dental cyst. Without treatment, infection can seriously damage gum tissue, teeth, and underlying bone.

  • Over-Vigorous Brushing

Brushing too hard or using the wrong brush can cause gum irritation. Do your gums (and teeth!) a favor by using proper brushing technique—massage, don’t scrub—and always use a soft-bristled brush.

Spots of Discoloration

Sometimes you notice a patch of lighter or darker tissue that you haven’t seen before. A spot that is different from the gum tissue around it can be harmless or need further attention.

Contact our Marysville, WA office if you have any recent discoloration, sores, pain, lumps, or any differences in appearance or sensation in your mouth. There are several types of oral cancer and prompt diagnosis and treatment is important to prevent the spread of cancerous cells.

You know your smile better than anyone. Any time you see a change in the usual appearance of your gums, it’s important to see Dr. Kelly Peterson. Treating gum problems before they become serious is one of the best ways to keep yourself—and your smile—in the pink of health!

Teens and Gum Disease

March 6th, 2024

You have a lot going on. School. Sports. Activities. Family. Friends. Teens lead busy lives and have busy schedules, so you need to budget your time and energy. One thing you don’t want to spend any of your time and energy on? Dealing with gum disease.

Gum disease most often begins as a reaction to plaque and tartar. The bacteria in plaque produce acids which irritate gum tissue, causing inflammation, swelling, and bleeding. This is gingivitis, the early stage of gum disease.

Left untreated, early gum disease can become periodontitis. Periodontitis is a serious gum infection which can cause receding gums, loose teeth, and even tooth and bone loss.

We usually think about gum disease as something that only older adults worry about. But the unfortunate fact is that children and teens are also at risk for gum disease—and the teen years bring special risks. Why?

  • Braces

The teen years are the most common years for orthodontic treatment. Wearing traditional or lingual braces can make removing plaque from around brackets and wires, between the teeth, and near the gum line more challenging, and gum disease can be the result. When you’ve been working so hard to create a healthy attractive smile, you don’t want to delay your orthodontic progress to treat gum disease.

  • Less-than-Nutritious Snacking

When you have after school commitments like sports practices, play rehearsals, or work, you probably carry a snack to give you the energy you need until dinner. Popular snacks like energy drinks, chips, or candy bars are common go-to choices, but they contain acids, simple carbs, and sugars which are bad for both gums and tooth enamel.

  • Hormones

Increased hormone levels during puberty can make the gums more sensitive and more easily irritated.

  • Your Busy Life

Maybe you’re not getting enough sleep. Or eating as well as you could. Or you’re feeling anxious. Lack of sleep, poor nutrition, and stress can affect your body’s immune system and your ability to fight off infection. And if you’re also not brushing and flossing regularly, your gum health can really suffer.

How do you know if you have gum disease? Good question! Sometimes the early stages of gum disease aren’t obvious. Perhaps you’ve noticed changes in your gums, such as:

  • Redness
  • Swelling
  • Soreness
  • Bleeding
  • Bad breath even after brushing

Any of these changes can be symptoms of gum disease and are a good reason to give our Marysville, WA office a call, since time is important when treating gum disease.

Caught early, gingivitis is usually very treatable—in fact, you can often reverse early gingivitis by paying more attention to your daily dental hygiene. If gingivitis is more advanced, or if periodontitis develops, you need professional dental care to prevent serious damage to your gums, teeth, and bone.

Preventing gum disease from ever developing is always best, though, so let’s look at what you can do to keep gum disease from becoming a problem.

  • Keep Up with Healthy Dental Habits

Even though you’re leading a busy life, take time for your dental care. Brushing twice a day for at least two minutes per session and flossing once a day take just a bit of your time and are the best way to keep your gums healthy. If you wear braces or have a tendency toward cavities and gum disease, Dr. Kelly Peterson might recommend brushing or flossing more often.

  • Use the Right Tools

Using the right tools makes a big difference. You should always choose a toothbrush with soft bristles to protect your delicate gum tissue—especially if it’s extra sensitive. Too-harsh brushing can damage even your super-hard tooth enamel, so you can imagine what it can do to your gums! Change out your brush every three to four months when it starts to get frayed and worn.

If you wear braces, ask Dr. Kelly Peterson to recommend the best kind of floss to clean between your teeth and around your brackets and wires. The right tools will make flossing a lot easier, and will help you keep your gums healthy and your orthodontic treatment on track.

  • No Matter How Busy You Are, Treat Yourself Well

Watch your diet. Drinking water to hydrate is a healthy (and inexpensive) alternative to sugary and acidic drinks. When you know you have after-school commitments, pack yourself a healthy snack. After snacking, it’s a good idea to rinse with water when you can’t brush to remove any food particles sticking around your teeth and gums.

And even though your schedule is demanding, caring for your mind and body should be a priority. If you have difficulties with sleep or stress, or questions about a nutritious diet, talk to your doctor for some valuable tips to make your daily life healthier and more enjoyable.

With so much going on in your active life, gum problems are problems you really don’t need. Make room in your schedule now for careful daily brushing and flossing, a healthy lifestyle, and regular visits to Northwest Smile Design, and you’ll be living that active life with a beautiful, healthy smile!
