Is this a trick question? After all, you and your family probably already know quite a lot about cavities:

• It all begins when bacteria-filled plaque sticks to teeth and starts to attack enamel. How?
• Because the bacteria in plaque use the sugars and other foods we eat to produce acids.
• These acids gradually weaken teeth by dissolving minerals that help make up our enamel (a process called demineralization).
• Over time, a hole, or cavity, develops in the tooth surface.
• Left untreated, bacterial decay can spread to the inside of the tooth, creating a more serious cavity.

Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes might discover an unexpected cavity at a regularly scheduled dental exam at our Chicago office, but there are also some symptoms that should have you calling for an appointment. A cavity can cause sensitivity when eating something hot or cold, or it can be painful, or you might even notice visible discoloration or damage to the tooth surface.

So, if your child has any of these symptoms, it’s a cavity, right? It might be—but it might not. Sometimes, because the symptoms are similar, what we suspect is a cavity is really enamel erosion.

The bacteria-created acids weaken enamel. But it’s not just bacteria that subject our teeth to acids. Acidic foods are one of the leading causes of tooth erosion.

And while we expect damage from a lifetime of acidic foods and beverages to catch up with us as we age, the fact is that erosion is becoming a problem even for young children. How is this possible? Let’s look at some food chemistry.

Our normal saliva pH level is around a 7, which is neutral. Any number lower is acidic; any number higher is alkaline. Acidic foods have a low pH (the pH of lemon juice, for example, measures between 2 and 3), and can reduce our normal, neutral pH level. When saliva pH levels drop to 5.5 or lower, tooth enamel starts to demineralize, just as it does when exposed to the acids from oral bacteria.

Regularly snacking on citrus and other acidic fruits, fruit juices, flavored drinks, sour candies, and other acidic foods can cause enamel erosion. Especially erosive are sports drinks, energy drinks, and colas, because they contain some combination of citric acid, phosphoric acid and/or carbonation.

So, when might you suspect enamel erosion? Your child might be sensitive to hot or cold foods, or feel pain, or even have noticeable enamel loss or pitting. Even though these symptoms may not have been caused by plaque and bacteria, acidic erosion from our diets leaves weakened enamel just as vulnerable to cavities and decay.

How to avoid erosion?

• Serve acidic foods sparingly, or as part of a meal. This helps our saliva pH stay in the neutral zone.
• Balance acidic foods with low-acid choices to neutralize acids and restore a normal pH balance. For example, mix those acidic berries with a banana.
• Use a straw! These are not only fun, but this simple solution keeps erosive drinks from bathing young teeth in acids.
• Encourage your child to drink water instead of an acidic beverage, or drink it afterward to rinse acids away. The pH of pure water? A perfect, neutral 7. And by using tap water instead of bottled water, you’ll be providing fluoride, which helps strengthen enamel.
• What about brushing right after eating or drinking something acidic? Ask Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes if your child should rush for the brush. We may recommend waiting 30 minutes or so after an acidic treat to give the teeth time to remineralize. Otherwise, brushing might cause more wear and tear on enamel.
• Finally, while foods are often the source of acid erosion, medical conditions can cause erosion as well. Talk to us about ways to minimize erosion while addressing these medical needs.

Be proactive. Ask your Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes about healthy drinks and snacks for healthy teeth. Make sure to keep on top of brushing and flossing, and stick with fluoride toothpastes. And visit our Chicago office regularly for exams and cleanings.

There’s really no trick to it—preventing enamel erosion helps keep your child’s teeth structurally strong and cavity-free for a lifetime of beautiful and healthy adult smiles.

So much of parenting is a balancing act. Making sure your child has enough play time and enough nap time. Crafting meals that are both healthy and appealing. Making sure every dental product you use is both effective and safe.

While Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes and our team can’t recommend the perfect bedtime story, or tell you why your child just won’t go for that delicious steamed broccoli, we are more than happy to discuss the very best ways to promote healthy, strong teeth. Should fluoride toothpaste be part of your child’s dental routine? For many good reasons, the answer is yes.

Why Fluoride is Important

Our enamel is the strongest substance in our bodies, with the highest concentration of minerals, but it is not indestructible. The bacteria that live in our mouths create acids which attack our enamel. Weakened enamel leads to cavities. Fluoride is a mineral that makes the enamel surface more resistant to these acids, and can actually help our enamel repair itself in a process called “remineralization.” Fluoride helps prevent cavities and makes teeth stronger, and those are benefits that will last your child a lifetime.

Can There Be Too Much of a Good Thing?

Fluorosis is a condition that can sometimes develop when a child has been exposed to too much fluoride while the adult teeth are developing below the gum line. (Around the age of eight, children’s teeth have finished forming and are not at risk.) Fluorosis is not a disease, and doesn’t harm teeth, but can lead to faint streaks in the enamel. While this streaking is usually white and subtle, it can sometimes be darker and more noticeable. Teeth discolored by fluorosis can be treated cosmetically, but prevention is always the best option.

Finding the Perfect Balance

Talk to us about using fluoride toothpaste when your baby’s first teeth start arriving. If a very young child is at risk for tooth decay, we might recommend early use of fluoride toothpaste. And for these small children, younger than the age of three, a small smear of paste (about the size of a grain of rice) is sufficient if needed. Swallowing fluoride products increases the risk of fluorosis, so make sure to use a very small amount of paste.

Because young children can’t understand the concept of rinsing and spitting, you always want to make sure the amount of toothpaste you use is age-appropriate even as they get older.  From ages three to six, a pea-sized dab of toothpaste is enough. Children should not use fluoride rinses or supplements unless recommended, and should be monitored to make sure they spit out fluoride toothpaste or rinses after brushing.

Most drinking water already has natural levels of fluoride, which normally aren’t a problem. If you are concerned about high fluoride levels in your local water, talk to us. If your water has higher levels of fluoride than normal, you can minimize consumption when your baby is young by breastfeeding, using non-fluoridated water for mixing with formula powder or concentrate, or buying prepared formula. If your child is a toddler, don’t add fluoride rinses or supplements unless they are recommended by a dental or medical professional.

Talk to us during your visit to our Chicago office about protecting your child’s teeth. We are happy to help you find just the right amount of fluoride to keep young smiles stronger and more resistant to tooth decay. Healthy teeth in a beautiful smile—that’s a perfect balance!
