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. Jason P. Tosto know how your experiments turned out the next time you visit our Hellertown, PA office!

Remember all the things your parents would tell you when you were growing up to scare you away from doing something? Like how lying might make your nose grow, misbehaving meant you wouldn’t get money from the tooth fairy, and swallowed chewing gum would build up in your stomach and stay there for years?

Maybe that last one stayed with you well beyond your teens, and occurred to you every time you accidentally (or purposely) swallowed a piece of gum. We don’t blame you. It’s a scary thought.

But is it true?

We hate to take the fun out of parental discipline, but swallowing a piece of chewing gum is pretty much like swallowing any other piece of food. It will move right through your digestive system with no danger of getting stuck for months, let alone seven years.

This doesn’t mean you should start swallowing all your gum from now on, but if it happens accidentally now and then, there’s no need to panic.

Another common gum myth is that sugar-free gum can help you lose weight. Although it is preferable to choose sugar-free gum over the extra-sweet variety, no studies have show that sugar-free gum will help you lose weight.

If you pop a piece of gum in your mouth after dinner to avoid dessert, it could help you avoid eating a few extra calories every day. But the consumption of sugar-free gum without any other effort will not help you shed pounds.

 If you really enjoy chewing gum, we strongly encourage you to select sugarless gum, because it lowers your risk for cavities. Many brands of sugarless gum contain xylitol, a natural sweetener that can, in fact, help fight bacteria that cause cavities and rinse away plaque.

So if you can’t kick the gum habit altogether, sugar-free is definitely the way to go!

If you have any questions about chewing gum, feel free to contact Dr. Jason P. Tosto at our Hellertown, PA office.

Every January 1^st, you have your resolutions ready. No more nail biting. Lose ten pounds. Stop smoking. None of us are happy about those annoying bad habits we’ve picked up over the years. But if nothing else has helped you keep your resolutions, maybe seeing how they can improve your oral health will give you some extra willpower.

• No More Nail Biting

You can easily see how nail biting affects your fingernails, but its effects are more than cosmetic. The pressure this habit puts on tooth enamel can lead to cracks, chips, and enamel erosion. Nail biters have a greater risk of bruxism, or teeth grinding. (More on that below.) And the transfer of germs from fingers to mouth and mouth to fingers is a vicious circle that can lead to illnesses and infections in both fingers and mouth.

• Cut Down on Junk Food

Sugars and carbs help pack on the pounds, no doubt. Did you know that they can also help create cavities? Sugar is a favorite food for oral bacteria, which allows them to produce acids which attack and weaken tooth enamel. And carbs? They convert easily to simple sugars. Choose nutritious snacks and beverages, and you will keep those teeth healthy. You might even lose a few pounds!

• Lower the Volume

If your partner complains about sleepless nights thanks to your nocturnal teeth grinding, or your friends ask you to quit chewing on that cup of ice while they’re trying to watch a movie with you, listen to them! (If you can hear them over the grinding and chewing.) Bruxism can fracture teeth, cause headaches and jaw problems, and might even lead to loose teeth. Chewing hard foods can have the very same effects. Too much pressure from any source can damage your teeth. Grinding, chewing ice, crunching down on hard candies—any habit that’s loud enough to annoy others could be a warning to be more careful of your teeth.

• Don’t Put That in Your Mouth!

Helping you eat and chew nutritious foods—of course. Smiling—absolutely. Ripping off a piece of duct tape, tearing open a potato chip bag, holding your dog’s leash while you look for your keys, opening a tight bottle cap—no, no, no, and really no. Fractures and chips are common injuries when you use your teeth as tools. Your teeth have a crucial job to do, but that job description never includes “scissors” or “nutcracker” or “bottle opener.” Take that extra minute and find the tool you need!

• Drink in Moderation

Along with all the other consequences of over-indulging, too much alcohol in your diet can be bad for your oral health. Alcohol, especially paired with sugary drinks, helps create that acidic environment that leads to weakened enamel. More than that, it’s dehydrating. Without sufficient hydration, we don’t have the optimal saliva production we need to fight cavities. After all, saliva helps wash away food particles and bacteria, neutralizes acids, and strengthens enamel through remineralization. Ring in the New Year—moderately!

• It’s Time to Quit

Cigarettes, pipes, cigars, chewing tobacco—there is no tobacco product that is healthy for your body or your teeth! We’re all familiar with the discoloration tobacco can cause, but it also has serious oral health consequences. Oral cancer, gum disease, early tooth loss—all these conditions have been linked to tobacco use. Today there are more methods than ever before to help you quit. Make this your year!

You don’t have to wait for the New Year to start working on healthier habits. If you’d like to tackle teeth grinding, banish nail biting, stop smoking, or work on any other habits that can damage your health and your teeth, talk to Dr. Jason P. Tosto at your next visit to our Hellertown, PA office. And, don’t forget—resolving to see us twice a year for a checkup and a cleaning is a resolution that’s extremely easy to keep!

Imagine this scenario: you go to the dentist to have a cavity filled, and an hour after the procedure you have a runny nose, scratchy throat, and your arms are breaking out in blotchy, red hives. In other words, you’re in worse shape after the visit to the dentist than you were before you walked in to have the cavity fixed. If you experience any of these types of symptoms or side effects, chances are you have a latex allergy.

What is a latex allergy?

A latex allergy is a hypersensitivity to latex proteins. If you have this allergy, the Centers for Disease Control and Prevention recommend that you avoid direct contact with any materials that contain latex. While latex gloves are known to cause allergic reactions in people with a latex allergy, certain metals, plastics, and other materials used in dental care can also cause an adverse response.

A runny nose and itchy eyes are common allergic reactions to latex. However, Dr. Jason P. Tosto and our team at Tosto Family Dentistry want you to know it can also trigger more severe symptoms, including asthma, wheezing, and cardiovascular and gastrointestinal ailments.

A latex-safe dental environment

Many dental offices screen patients for a latex allergy. This is only beneficial, however, if you’re already aware you have a latex allergy. The best thing you can do to ease your allergies is to find a dentist who has a latex-safe environment. A latex-safe dental environment observes the following protocols:

• All patients are screened for a latex allergy.
• No personnel use latex gloves.
• All latex products are removed from the patient’s vicinity, including rubber dams and elastics.
• Work areas contaminated with latex powder are cleaned frequently.
• Signs are posted to communicate all latex allergy procedures in case of an emergency.

If a latex allergy is part of your medical history, then it’s in your best interest to find a latex-free dental environment. To learn more about latex-free dentistry, or to schedule an appointment with Dr. Jason P. Tosto, please give us a call at our convenient Hellertown, PA office!
