Why all the fuss about fluoride? Your dentist recommends it, your toothpaste is formulated with it, most of our drinking water contains it. Just what is it about this mineral that makes dental professionals sing its praises? Read on for three good reasons why fluoride is a healthy choice for healthier teeth.

1. Fluoride Works!

Fluoride is an attractive option for protecting your teeth—and we mean that literally. Fluoride protects the surface of your teeth by working on a molecular level to attract minerals which strengthen enamel and help prevent cavities.

Our tooth enamel is mostly made from calcium and phosphate ions. These elements combine to form hydroxyapatite, strong crystals which make up about 95% of our enamel. Hydroxyapatite is so strong, in fact, that tooth enamel is the hardest part of our bodies. What can go wrong?

Acids. Acids created by the bacteria in plaque and the acids in our diet strip away the calcium and phosphate ions in enamel, weakening the surface of the tooth. This process is called demineralization. Over time, weak spots become bigger as acids eat through enamel to the inner tooth, causing decay and cavities.

So, what can fluoride do?

First, fluoride helps remineralize tooth enamel. Fluoride is attracted to the tooth’s surface and bonds with its minerals. It also attracts the calcium and phosphate ions which are found in our saliva to restore any minerals which have been lost. This process helps repair any weak spots that might have begun to form.

But fluoride does more than restore and repair tooth strength—it improves it! Fluoride ions join with calcium and phosphate to form fluorapatite crystals, which are larger and stronger than hydroxyapatite crystals.

Want more? Fluoride may interfere with bacterial plaque’s ability to produce acids. Since plaque and its acids are a major cause of gum disease, brushing with a fluoride toothpaste is a great way to help prevent plaque buildup around and below the gum line—buildup that leads to irritated, inflamed, and infected gum tissue.

2. Fluoride Is Doubly Effective

Fluoride works both externally and internally. We just looked at how fluoride helps keep teeth strong when applied to the outside of the teeth. This is called a topical application. Systemic benefits come the fluoride we consume in our diets.

Fluoride isn’t found in many foods, but it is found naturally in lakes, rivers, and other water sources. When the local water’s fluoride level is low, many communities add fluoride for its proven ability to prevent cavities. Water fluoridation is safe, has been studied for decades, and has been shown to reduce the risk of cavities by 25% or more for both children and adults.

Systemic fluoride is especially important for your child’s dental health. This is because fluoride incorporates with minerals in the adult teeth while they are growing and developing, creating stronger, more cavity-resistant teeth even before they erupt. Most adult teeth have finished forming around age eight, so, if your community doesn’t have fluoridated water, it’s a good idea to discuss other options with your child’s dentist.

And we grown-ups benefit, too! When you drink fluoridated water, you’re increasing the amount of fluoride in your saliva. Just like fluoride toothpaste, saliva bathes your teeth with fluoride ions, strengthening the tooth surface, and helping to neutralize the acids which damage teeth and gums.

3. It’s Easy to Get Fluoride Protection

Most toothpastes are formulated with fluoride, so you’re getting the enamel-strengthening benefits of this mineral whenever you brush—at least twice each day. Since children can’t really grasp the “rinsing” and “spitting” steps of the brushing routine just yet, talk to our doctors about how to introduce tiny amounts of fluoride toothpaste to your child’s dental routine. Baby steps!

Because so much of our drinking water is fluoridated, most of us really don’t have to think about how to get the recommended amount of fluoride each day. If your community’s water is low in fluoride, we can help you here as well. Prescription fluoride rinses, gels, supplements, and other treatments are available to make sure that your teeth are well-protected, wherever you may live. We will let you know which products are best for you and how often to use them during your next visit to our Green Bay dental office.

Fluoride isn’t, of course, the only way to look out for your dental health. Proper brushing and flossing are still essential for removing plaque. Check into sealants for both kids and adults for long-lasting protection for chewing surfaces. But when it comes to a proven cavity-fighter and plaque-reducer that is simple to use, effective, and easily available—is it any wonder we’re big fans of fluoride?

What’s life like for the average 60-year-old today? It’s complicated! We travel. Or we work out. Or we relax with friends. We pursue favorite hobbies or we develop new ones. We work, or start businesses, or volunteer for schools, museums, and charities. We practice the art of writing letters or we text our grandchildren. Whatever else we do, we do our best to stay healthy so we can live our lives to the fullest.

Part of living our lives to the fullest means caring for ourselves. And caring for ourselves means learning how to look out for the potential dental problems that might come with age, and how to keep ourselves in the best of dental health.

• Gum Disease

Gum disease, or periodontitis, is not uncommon in older patients. Certain medical conditions, such as diabetes, can leave you more vulnerable to gum disease. Because gum disease is often symptom free, it can remain unnoticed until the disease has progressed. Good oral hygiene and regular visits to the dentist are the best means of prevention—we are trained to discover gum disease in its earliest stages, and can treat it before the disease causes serious damage to gums, teeth and bone. But if you have delayed seeing a dentist, the good news is that there are many methods of treating gum disease available, including antibiotics, professional plaque removal, and periodontal surgery.

• Tooth Decay

As we age, our gums can recede from the teeth. The new root area that is exposed is more vulnerable to decay because it is not shielded by the hard enamel which protects the upper part, or crown, of the tooth. Maintaining your brushing and flossing routine is the best way to keep cavities from developing. If gum recession is severe, there are surgical methods we can discuss to restore gum health.

• Time

Cosmetically, teeth can yellow with age as the dentin beneath the enamel darkens and the enamel covering it thins. Years of coffee, wine, smoking and other stain-makers take their toll. If you are self-conscious about the appearance of your smile, talk to us about suggestions for whitening and brightening.

Medically, over time our teeth are subject to damage. Enamel and tooth surfaces can wear away, leaving our teeth more at risk for breaks or fractures that can lead to infection, which can result in the need for root canal work. Simple chewing puts an amazing amount of pressure on the teeth—and if you grind your teeth, there is even more stress placed on them. See us regularly for ways to maintain strong teeth, to repair damage if necessary, and to keep your gums and bones healthy if you are a denture wearer.

• Dry Mouth

Dry mouth can be a problem for older patients, often caused by medical conditions or medications. When we produce saliva, it helps remove sugar and the acids sugars produce which attack our enamel. Without normal saliva production, we are more vulnerable to cavities. Dry mouth can also lead to mouth ulcers, oral thrush, sores and infections. If you have been suffering from this condition, talk to us. our doctors and our team have suggestions that will help.

• Oral Cancer

Oral cancer is something we look for during every check-up. And, if you ever notice any change that causes you concern, call us immediately. Early treatment of oral cancer and other oral diseases leads to the best possible outcome.

• Keep Up With Your Dental Care

The best way to keep our teeth and mouths healthy as we age is with prevention. Regular daily brushing and flossing and office visits twice a year for an examination and a professional cleaning are habits that should last a lifetime. Make sure to tell us about any medical conditions you may have and any medications you are taking, to avoid interactions and relieve unpleasant side effects.

What’s life like for the average older person today? There is no average older person! As we age, we are free to explore our interests in any number of creative and individual ways. But there is one goal we have in common: we all want to keep our smiles healthy and attractive. Call our Green Bay office for preventative and restorative care. We want to help you work toward an ageless smile!

One of the most charming aspects of your baby’s beautiful smile is his brilliantly white teeth. But now that his adult teeth are coming in, the difference in color is very noticeable. Is this something to be concerned about? Happily, probably not.

Both baby teeth and adult teeth have the same basic structure. The inside of the tooth, the pulp, contains blood vessels and nerves. The pulp is covered by a layer of dentin, a hard, yellowish substance composed of living tissue that helps protect the pulp and transmits signals for pain, pressure, and temperature. Enamel is the outer protective covering of the tooth, and its natural color can vary from greyish-white to light yellow.

If primary and permanent teeth are so alike, how can they look so different? As with so many things, the difference lies in the details. In adult teeth, enamel is semi-translucent, so it will allow the color of what is beneath it to show through. And the color of the thick dentin beneath is naturally yellow. Baby teeth have a thinner layer of the yellowish dentin. And while their enamel is also thinner, the enamel in baby teeth is generally whiter and more opaque, so less of the underlying yellow from the dentin is visible.

The result of these small differences is that adult teeth are normally darker than baby teeth to begin with. And when a permanent tooth that is just a bit darker erupts next to a bright white baby tooth, it is going to look even more yellow than it actually is. Once all of the baby teeth in front have been replaced with adult teeth, you will have a much better idea of their real color without unflattering comparisons!

There are times when concerns about tooth color should be looked at by our doctors more closely.

• Unusual discoloration in teeth should be examined. Some discoloration is caused by medical conditions such as hypomineralization, some by environmental factors such as excess fluoride, some by trauma, some by medication. If you notice a discolored section of your child’s tooth, or the tooth has turned a different shade from the teeth around it, give us a call.
• Your child might have naturally whiter or yellower teeth simply as a matter of genetics. If your child is self-conscious about the color of his teeth, we can talk about whitening solutions when he is old enough to use them safely. Home whitening products should never be used on young children.

Give yourself time to adjust to your child’s new, adult smile. You will probably notice no difference at all once all of his permanent teeth come in. And keep those new teeth their brightest with consistent brushing and flossing, and regular checkups and cleanings at our Green Bay office. This is the simplest prescription for a charming, white, and healthy smile at any age.

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!
