Educational and Entertaining Enamel Experiments

October 2nd, 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!

Whitening Teeth with Braces

October 2nd, 2024

Now that you are working hard to improve your dental health and appearance with your braces, it might seem like a logical time to whiten your teeth as well. But should you go ahead with home kits or a professional whitening? The answer might be yes, but not quite yet!

Toothpaste

The easiest way to whiten teeth is regular use of a whitening toothpaste. But these do not make a major difference in tooth color and may also contain abrasives which can damage ceramic brackets and make them more likely to stain. And, whether you have metal or ceramic braces, the brackets used are bonded to your teeth. Any part of your tooth covered by a bracket will not be affected by the whitening paste. Ask our office if you are thinking of using one of these products. We will be happy to recommend the best toothpastes to use while your braces are in place.

Whitening Strips and Trays

Whiteners can be applied at home with strips or tray kits. Strips are coated with a whitening gel and then pressed around your teeth. Tray kits provide a mouthguard-like appliance, which is filled with whitening gel. But neither strips nor tray solutions will whiten any area covered by brackets. When your braces come off, there might be noticeable differences in color on each tooth. Strips are difficult to apply with braces, and trays need to be custom-designed to fit your braces and make sure they don’t disturb your orthodontic work. One size most definitely does not fit all! Finally, these whitening agents can cause tooth and gum sensitivity, especially around the time of adjustments. Many manufacturers do not recommend using their products while you have braces. Please talk to us if you are thinking of using them.

Professional Whitening

A dental professional can whiten your teeth in office for the best possible results. The most effective treatments for your unique teeth are combined with protective care of your gums and mouth. Whether this treatment is appropriate while you have braces is something we are happy to discuss.

The best way to keep your teeth bright is to keep up your regular dental routine! Brushing and flossing are more important than ever now, because plaque builds up around brackets. Avoid foods that stain teeth and rinse or brush after every meal and snack. Dr. Werner will show you the best way to take care of your teeth while your braces are on—and that includes the best way to keep them white and bright. Talk to us about the perfect time to whiten your beautiful smile during your next visit to our Los Gatos, CA office. And if you have to wait a few extra days for the smile you’ve been working toward, truly, the wait will be worth it!

Ouch! Are You Biting Your Cheeks More Often?

September 25th, 2024

You’re biting into something delicious, and, Ouch! You bite into something you didn’t mean to—the inside of your tender cheek.

Painful moments like this happen every now and again. But if you find that more frequent cheek biting means that you’re extra-cautious when eating or speaking, if you wake up with sore cheeks in the morning, or if you catch yourself habitually chewing on your cheeks during the day, it’s time to visit our Los Gatos, CA office.

Causes of Cheek Biting

Many of us experience the occasional cheek chomp when we’re eating or talking. No fun! Besides the pain, a bite can cause broken skin, inflammation, a canker sore, or a mucous cyst. Luckily, the discomfort from these accidental bites generally resolves after a few days.

Sometimes, though, biting becomes a more frequent annoyance. Regular bites can be caused by several conditions, including:

  • Sleep Bruxism

Bruxism is the medical term for tooth grinding. When sleepers unconsciously clench or grind their teeth as they slumber, it’s known as sleep bruxism. Sleep bruxism not only causes tooth damage, jaw problems, and facial pain—that nightly gnashing can mean bites to delicate cheek tissue.

  • Problems with Dental Restorations

The placement of a crown, bridge, or implant can cause biting to occur more often if the alignment of your restoration with your other teeth isn’t ideal or has shifted, or if the restoration needs replacement.

  • Wisdom Teeth

Most of us don’t have the room to welcome four new—and large—teeth. When wisdom teeth come in, they can lead to cheek bites, especially if they erupt leaning outward toward your cheeks.

  • Orthodontic Misalignment

If you notice that you seem to be biting your cheek a lot when eating or speaking, it could be an orthodontic problem.  When your teeth or jaws don’t align properly, if your mouth is small, or if your teeth have shifted over time, your cheeks might feel the consequences.

Treatment Options

Why see Dr. Werner? A one-time bite can be extremely uncomfortable, and might lead to inflammation or even a sore spot inside your mouth. Usually, both pain and sore spot fade in a short while, and saltwater rinses or oral gels can soothe your injured cheek tissue. Your dentist’s office can give you advice on treating minor bites.

But what about continuous biting? Regular biting injuries can lead to bigger problems. Tissue in the cheeks can thicken or erode. Scar tissue can build up inside the mouth. Ulcers and other sores can become larger and more painful.

If you’ve been biting your cheeks more often, Dr. Werner can diagnose the cause and offer you treatment options depending on the reason for this frequent biting:

  • Sleep Bruxism?

Dr. Werner might suggest a nightguard to provide protection from the damaging effects of bruxism. Nightguards not only prevent further biting, they give your cheeks the chance to heal. We can custom fabricate a guard for the most comfortable and effective fit.

  • Restoration Problems?

If regular cheek biting occurs after you’ve gotten a crown, a bridge, or an implant, visit our Los Gatos, CA office. This might be a problem that can be resolved with a bit of reshaping, whether removing a bit of the restoration or building up a spot. If a crown or other restoration has shifted or is failing, replacement might be in order.

  • No Room for Wisdom Teeth?

Most of us don’t have room in our mouth to accommodate wisdom teeth, and extracting them is a common dental procedure. Wisdom teeth can be the source of many dental problems, including impaction, shifting teeth, and even damage to surrounding teeth. If you see signs that your wisdom teeth are starting to come in, talk to your dentist about your options.

  • Orthodontic Problems?

Orthodontic treatment can improve tooth and bite alignment—and can eliminate those painful cheek bites if misalignment is what’s causing them. Modern orthodontic treatment offers patients of all ages more options than ever before, including traditional and lingual braces, clear aligners, and functional appliances.

Whatever the reason for painful cheek biting, you deserve to eat and speak and enjoy your day without constant “Ouch!” moments affecting your comfort and health. If these moments are happening all too often, visit Erich M. Werner, D.D.S. for the answers to your biting problems.

Just What Is Plaque?

September 25th, 2024

From the time you were small, you’ve been warned about the dangers of plaque. Why? Because:

  • It’s an unappealing film that sticks to your teeth
  • It causes cavities
  • It causes gum disease

And really, do we need to know much more than this to motivate us to brush? But if you’re in a curious mood, you might be wondering just how this soft, fuzzy film accomplishes all that damage. Let’s take a closer look at the sticky problem of plaque.

How does plaque form?

We live with hundreds of species of oral bacteria, most of which are harmless, and some of which are actually beneficial. But when our oral ecosystem gets out of balance, problems can occur. For example, without regular and thorough brushing and flossing, we start to build up plaque.

Plaque starts forming within hours of your last brushing. And even though plaque fits the very definition of “seems to appear overnight,” this biofilm is actually a complex microbial community with several different stages of development.

  • It starts with saliva.

Saliva is vital to our oral health, because it keeps us hydrated, washes away food particles, neutralizes acids in the mouth, and provides minerals which keep our enamel strong. Saliva also contains proteins, which help form a healthy, protective film on the tooth surface. This film is called a pellicle.

  • Bacteria attach to the pellicle.

There are species of oral bacteria that are able to attach themselves to the pellicle film within hours of its formation. As they become more firmly attached, they begin to grow and divide to form colonies, and are known as the early colonizers of the plaque biofilm.

  • A complex biofilm forms.

If you’ve skipped brushing for a few days (please don’t!), you’ll notice a fuzzy, sometimes discolored film on your enamel—that’s a thriving plaque community, and it only takes a matter of days to go from invisible to unpleasant.

If you’re not removing plaque regularly, it can harden further and become tartar. And once you have tartar buildup, you’ll need the care of a dental professional to remove it.

  • What happens if we ignore plaque and tartar?

We get cavities and gum disease.

How does plaque cause cavities?

  • The bacteria in plaque, like all organisms, need nutrients.

Our normal oral environment and the food in our everyday diets provide the nutrients plaque needs. And, as we mentioned above, certain types of oral bacteria convert these nutrients into acids. Foods such as carbohydrates, starches, and sugars are most easily converted into acids, which is why we recommend that you enjoy them in moderation.

  • The biofilm promotes acid production.

Within the plaque film, anaerobic bacteria (bacteria which don’t use oxygen) convert sugars and starches into acids. As the plaque film becomes denser, it blocks acid-neutralizing saliva and oxygen from reaching these bacteria close to the tooth’s surface, creating an ideal environment for the bacteria to produce their acid waste products.

  • Acids attack enamel.

The sticky nature of plaque keeps these acids in contact with tooth enamel, where, over time, acids dissolve minerals in enamel, weakening the mineral structure of the tooth.

How does plaque cause gum disease?

  • Bacteria cause inflammation and gingivitis.

The bacteria in plaque irritate the delicate tissue of the gums, which causes an inflammation response which can leave your gums swollen, red, bleeding, or tender. This early form of gum disease is gingivitis. Fortunately, good dental care and careful brushing and flossing can usually prevent and even eliminate gingivitis.

  • Plaque and tartar can lead to periodontitis.

When plaque and tartar build up around and below the gumline, the gums pull away from the teeth, leaving pockets where bacteria collect, leading to infection as well as inflammation. Infections and constant inflammation not only harm gum tissue, they can destroy the bone supporting the teeth. This serious gum condition is periodontitis, and should be treated immediately to avoid further infection and even tooth loss.

How do we fight plaque?

From the time you were small, you’ve learned how to fight plaque:

  • Brush at least twice a day for two minutes, and be sure to brush all of your tooth surfaces and around the gumline.
  • Floss to remove plaque from between the teeth and near the gumline.
  • Visit our Los Gatos, CA office for a thorough professional cleaning.

Be proactive. If you have any questions, talk to Dr. Werner about the best way to keep plaque at bay. We can show you the most effective ways to brush and floss, recommend anti-plaque toothpastes and rinses, even suggest plaque-revealing tablets if you’re missing some trouble spots.

We’ve only brushed up on some plaque basics, because there is a lot more to discover about this complex biofilm. Happily, even with all there is to learn about plaque’s growth and development, it’s reassuring to know that getting rid of it is quite simple—with just a soft-bristled brush, some dental floss, and a few minutes of your time each day, you’re on the way to a healthy, happy, plaque-free smile.
