This may come as a surprise, but brushing your teeth right after a meal can be one of the worst things you can do for your healthy teeth. A toothbrush can be considered an assault weapon against your smile if used immediately after eating certain foods.

Enamel is like the tooth’s shield. It is a hard mineral exterior on each of your teeth. In reality, enamel is the hardest part of the human body—even stronger than bone! I like to regard it as a “super-structure.” But every superhero has a weakness, and enamel’s kryptonite is acid.

A healthy tooth lives in a mouth that has a proper pH balance. When that balance tips from alkaline to acidic, a harmful process called demineralization begins. Demineralization occurs when acids attack and soften the tooth surface. Pores and fissures form and harmful bacteria move in.

With each bite of food or drink, our mouth pH fluctuates. Highly acidic foods tip the balance of your mouth from a healthy alkaline to a dangerous acid. Here are some examples of those sources of acid: citrus fruits, soda, and sugary foods. There are certainly many others, but these are the most common.

So how does brushing your teeth immediately after a meal make this process even worse?

After eating highly acidic foods, your teeth are susceptible to damage. When you brush your teeth in this weakened state you are actually damaging your enamel. The abrasive bristles of the brush wear away the protective surface of the teeth. You should avoid brushing for at least an hour, or take other, simple preventive measures immediately following a meal.

First, rinse with or drink clear water. Then chew some sugarless gum. Both of these practices will produce saliva, restore a healthy pH level in your mouth, and coat your teeth with nourishing minerals. Out of all the sugarless gums available, the best of the best are those that list xylitol as the first ingredient. Another option is to consume cheese, milk, or another non-acidic food or drink to conclude your meal.

After you have given your mouth time to return to a healthy pH, feel free to brush your teeth. Just keep in mind that any time you eat acidic foods, you weaken your teeth. Make sure not to worsen the problem by brushing immediately after dining and damaging your teeth even more. Questions? Call us at Shoals Pediatric Dentistry, PC.

Snacks can taste good and give your child’s energy a boost, but they can also be bad for teeth. Sugary, sticky snacks, such as candy, cookies, and snack cakes can lead to tooth decay if eaten regularly between meals. Still, there are plenty of fun snacks for healthy teeth.

The trick when selecting snacks is to avoid too many added sugars and refined carbohydrates that stay on the teeth and give bacteria a chance to ferment and produce acid from them, which can lead to tooth decay. In addition, snacks should provide nutrients to support a healthy mouth. These are five fun snacks you can feel good about giving to your child.

1. Yogurt and cereal.

Yogurt contains calcium, which is an essential mineral for strong and healthy teeth. Select plain yogurt or yogurt flavored with real fruit, rather than flavored yogurt that is sweetened with added sugar. We recommend choosing a whole-grain cereal, which is less likely to lead to dental caries. Choose a low-sugar or unsweetened cereal to avoid accidentally making the snack as sugary as a candy bar.

2. Tuna and whole-wheat crackers.

Canned tuna contains vitamin D, which is an essential vitamin for helping your body absorb and use calcium. Whole-wheat crackers are natural sources of antioxidants for a strong immune system, and they’re lower in refined carbohydrates than white crackers.

3. Bell pepper strips and hummus.

Red, yellow, and green bell peppers are excellent sources of vitamin C, which is an antioxidant. Vitamin C is also a good choice for supporting regeneration or maintenance of healthy gum tissue. Vitamin E is another antioxidant, and it also supports a healthy immune system. A strong immune system is protective against infections, such as bacterial infections associated with gum disease.

4. Turkey and cheese roll-ups.

Turkey is carbohydrate-free, so it doesn’t leave residues of sugars on teeth for bacteria to ferment. Lean ham is another good choice. Low-fat cheddar, mozzarella, or Swiss cheese is a good source of calcium as well as protein. For a more substantial snack that’s still low in carbohydrates and sugar, add a few celery sticks.

5. Peanut butter and carrots.

Peanut butter is another source of vitamin E. Carrots provide vitamin A, which is essential for a strong immune system. You can also substitute cauliflower or broccoli florets for the carrots, and ranch dressing for the peanut butter, and still have a snack that’s fun to eat and good for your child’s teeth.

While they may sound refreshing, especially after participating in sports activities or after a jog, recent studies suggest that energy and sports drinks can damage tooth enamel, thus elevating your cavity risk. These drinks are especially popular among our younger patients.

In the study, researchers analyzed the fluoride content and pH levels of 13 sports and nine energy drinks by soaking tooth enamel samples in the aforementioned drinks. The samples were soaked for 15 minutes in each drink, and then were soaked for two hours in artificial saliva four times a day for five days.

As much as sports drinks are harmful to your teeth, researchers found that exposure to energy drinks such as Rockstar, Monster®, and Red Bull® resulted in twice as much enamel loss as exposure to sports drinks such as Powerade®, Gatorade®, and Propel® (3.1 percent to 1.5 percent).

Yes, there are health benefits to consuming orange juice, fruit juices, sports drinks, and flavored waters, which can contain valuable ingredients such as vitamin C and other antioxidants; these drinks can also replenish nutrients lost during a sporting event and lower the chance of heart disease and cancer. But, if not consumed carefully, these beverages can harm your teeth. They are full of sugar, which converts to acid and wears away at your teeth, causing cavities, sensitivity, and eventually tooth loss.

Even one drink a day is potentially harmful, but if you are absolutely unable to give up that sports or energy drink habit, we encourage you to minimize their use and rinse with water afterward or chew a sugar-free piece of gum. Do not brush immediately after drinking them; softened enamel due to acid is easier to damage, even when brushing. Remember, it takes your mouth approximately 30 minutes to bring its pH level back to normal. The best thing to do is to wait an hour, then brush to remove sugar that lingers on your teeth and gums.

There are many sports drinks, energy drinks, and flavored waters out there today. Dr. Robin E. Lents and our team recommend you take the time to read the labels. Check for sugar content and citric acid in the ingredients. If you have any questions, or would like suggestions on the best sports drink options, please give us a call at our Florence office or ask us during your next visit!

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!
