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. Gary Yanowitz know how your experiments turned out the next time you visit our Cooper City, FL office!

Guilt is a powerful feeling. It can keep you from doing many things, including going to the dentist. The good news is that Gary Yanowitz, DDS is a judgement-free zone, and coming back (even after an extended period of being MIA) can be easier than you think. Our goal is to make you as comfortable as possible during your first appointment back with us — so here’s a little overview of what you can expect.

We’ll start with a series of dental X-rays, which are usually taken every three to five years. The set of X-rays will depend on your individual needs and it will help us get a more thorough look at what’s going on with your dental structure and keep an eye out for any prominent dental issues.

Next up will be your hygiene appointment. That appointment will consist of a review of your medical history and be followed by a thorough cleaning of your teeth. This is the perfect time to share concerns you may have about your oral health and ask us questions.

You’ll finish up with a comprehensive exam, which will review everything you covered with the hygienist. Dr. Gary Yanowitz will go over your medical history with you and address any dental concerns that might remain. If any special treatment is needed for such issues as cavities or broken fillings, we will discuss that with you as well.

Once all that is done, you’ll head over to the front desk to talk about payment and scheduling your next appointment. And that’s it! Your first visit back is an important step toward continuing to look out for your dental health.

Just because you slacked for a little while or life got in the way, this doesn’t mean things have to stay that way! We’re happy to help you get you back on track, so schedule an appointment at our Cooper City, FL office today!

HPV, or human papillomavirus, is the most common sexually transmitted infection in the country. There are over 100 strains of HPV, and, while most of these infections leave our systems on their own with no long-term ill effects, some cancers have been linked to certain “high risk” strains of the virus. One of these strains, HPV16, increases the risk of oral cancer.

HPV-related oral cancer most often appears in the oropharynx. This area of the mouth includes:

• The base, or back, of the tongue
• The soft palate
• The tonsils
• The back and sides of the throat

While HPV-related oral cancers can appear in other parts of the oral cavity, they most typically occur at the back of the throat and tongue and near the folds of the tonsils. Because of this location, oropharyngeal cancer can be difficult to detect. This is one more important reason to maintain a regular schedule of dental exams. Our examination doesn’t focus only on your teeth and gums. We are trained to look for cancerous and pre-cancerous conditions in the mouth, head, and neck to make sure you have the earliest treatment options should they be needed.

If you discover any potential symptoms of oropharyngeal cancer, call us for a check-up. These symptoms can include:

• Trouble moving the tongue
• Trouble swallowing, speaking, or chewing
• Trouble opening the mouth completely
• A red or white patch on the tongue or the lining of the mouth
• A lump in the throat, neck, or tongue
• A persistent sore throat
• Ear pain
• Unexplained weight loss
• Coughing up blood

Not every symptom is caused by cancer, but it is always best to be proactive. HPV-related oral cancer is rare, but it is on the increase. While HPV-positive oral cancers generally have a better prognosis than HPV-negative oral cancers, early diagnosis and treatment are still essential for the best possible outcome.

Finally, if you are a young adult or have an adolescent child, talk to Dr. Gary Yanowitz and to your doctor about the HPV vaccine, which is effective before exposure to the virus occurs. Most HPV vaccines, while not designed specifically to prevent oral cancer, prevent the HPV16 strain from infecting the body—the very same strain that causes the majority of HPV-related oral cancers.  Although no studies have shown definitive proof yet, there is strong feeling in the scientific community that these immunizations might protect against HPV-positive oral cancer as well as cervical, vaginal, and other cancers. It’s a discussion worth having at your next visit to our Cooper City, FL office.

Dr. Gary Yanowitz and our staff recommend that you replace your worn-out, germy toothbrush with a new one every three months. But most people either forget or resist getting rid of something that is still “working.”

Maybe if they had a few ideas for putting that old toothbrush to good use, more people would take our advice? To encourage good oral practices, we offer these ten fun things you can do with your used toothbrush:

1. Let your five-year-old budding Da Vinci create a masterpiece with some paint and your old toothbrush.

2. Scrub oily areas on your face with your toothbrush. The bristles are perfect for removing embedded dirt and oil that clogs pores.

3. Pamper your hamster by brushing his fur with an old toothbrush.

4. Dab a bit of Vaseline on the bristles and comb your eyelashes: instant glamour! Got dry, flaky lips? Slough away by using a toothbrush on your lips.

5. Remove the bristles: instant small plant stakes!

6. Old toothbrushes are great for spot-cleaning just about anything.

7. When nobody is around to scratch an unreachable itch on your back, turn that old toothbrush into your personal backscratcher.

8. Is your dog’s breath so bad that all your houseplants have died? Try brushing his teeth with your old toothbrush so that his kisses (and breath) are more tolerable.

9. Give your fish the cleanest tank in the neighborhood by scrubbing it with your old toothbrush.

10. Did you notice a few gray hairs sprouting from your hairline this morning? Old toothbrushes were made for touch-up dye jobs; works for dyeing your eyebrows, too!
