Building Blocks for a Healthy Grown-Up Smile

November 26th, 2025

Even before a baby is born, those tiny baby teeth are already forming. Expectant mothers can help ensure that their children’s baby teeth will be strong and healthy by getting the recommended amounts of proteins, vitamins, and minerals in their prenatal diets.

But a mother can’t “eat for two” to make sure her child’s adult teeth are healthy—children’s permanent teeth begin real growth and development only after birth. What can we do to encourage strong permanent teeth as our children grow and develop? Here are four important building blocks parents can use to lay a healthy foundation for their children’s grown-up smiles.

Serve a Tooth-Healthy Diet

The same vitamins and minerals that help create baby teeth are essential for creating healthy adult teeth. Tooth enamel, the hardest substance in the body, is almost completely made up of calcium phosphate minerals.  A diet which provides the recommended amounts of calcium and phosphorus helps your child’s body grow strong enamel. And don’t forget vitamin D, which our bodies need to absorb calcium and phosphorus.

A tooth-healthy diet should include several servings of foods which provide calcium, such as dairy products (milk, yogurt, cheese), dark leafy vegetables, and fortified juices, cereals and tofu. Phosphorus can be found in proteins like meat, fish, and poultry, as well as beans, nuts, dairy, and whole grains. Egg yolks and fatty fish are natural sources of vitamin D, and it’s easily available in fortified foods such as cow’s milk, soy milk, cereals, and orange juice.

Use the Right Amount of Fluoride

Fluoride is called “Nature’s cavity fighter” for a reason. Fluoride reduces the risk of cavities and helps strengthen tooth enamel. Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes can offer invaluable advice on when to start and how to use fluoride toothpaste to protect your child’s baby teeth and developing adult teeth.

Can there be too much of this good thing? While fluoride is a safe and effective way to protect teeth in normal, recommended amounts, too much fluoride can lead to fluorosis. This condition can cause cosmetic changes in the enamel of permanent teeth, from almost invisible lighter spots to darker spots and streaking.

How to make sure your child gets the right amount of fluoride?

For children under the age of three, use a dab of toothpaste no larger than a grain of rice. Ask Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes if fluoride toothpaste is recommended.

Young children can’t always understand the idea of spitting and rinsing after brushing, so children between the ages of three and six should use only a pea-sized dab of fluoride toothpaste, and need you there to make sure they spit and rinse afterward.

Ask us about local water fluoride levels if you have any concerns about using tap water for drinking or for mixing formula, keep fluoride toothpastes and other products out of the reach of children, monitor your children while they brush, and always check with us before giving your child a fluoride rinse or supplement.

Help Your Child Retire Harmful Thumb Sucking and Pacifier Habits

Your child might self-comfort with the help of a pacifier or thumb sucking, which can be a valuable soothing habit. But it’s important to talk to Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes to see just how long this soothing habit should last. Around the age of four, aggressive thumb or pacifier sucking can lead to problems for permanent teeth.

Vigorous sucking can cause protruding upper front teeth. Aggressive sucking can lead to changes in the shape of your child’s palate and jaw. Open bite malocclusions, where the upper and lower teeth are unable to meet, and overbites, where the upper teeth overlap the lower teeth more than they should, can also be the result of lengthy and forceful thumb sucking.

Take Care of Baby Teeth

Baby teeth are important! They bite and chew food, and they work with the tongue to help your child learn to pronounce words properly. And there’s one more important reason to make sure primary teeth stay healthy: they serve as the place holders which guide permanent teeth into their proper spots.

When a baby tooth is lost too early, due to decay or injury, the teeth on either side can drift into the empty space, preventing a permanent tooth from erupting where it needs to. Any misalignment or crowding which results may require orthodontic treatment in the future.

Call our Chicago office if your child unexpectedly loses a baby tooth. There may be no cause for concern, or, if there’s a potential problem, an appliance called a “space maintainer,” which keeps the baby teeth from shifting out of place, can be fabricated especially for your child.

Your child’s adult teeth are being formed now. Work with us to make sure the building blocks of present and future dental health are in place. You’re giving your child the foundation for a lifetime of beautiful, grown-up smiles!

Clean Toothbrush/Healthy Toothbrush

November 19th, 2025

We’ve all learned a lot about staying healthy lately. As a parent, you give good advice about avoiding germs in public places, cleaning things that get touched a lot like phones and keyboards, and learning the best way to wash hands. These small daily habits can have a big effect on your child’s health.

And since you’re already taking care of your little one by making sure they brush at least twice a day, we have some good advice for small habits which can make their toothbrush even cleaner and brushing even healthier.

Brushing Habits

Don’t let germs hitch a ride on your child’s toothbrush before they even begin brushing! Make sure their hands are clean before they start, and rinse off the toothbrush before they put it in their mouth.

After brushing, be sure your child rinses their brush carefully to get rid of leftover toothpaste and bits of food. Also, clean the toothbrush holder regularly to get rid of germs and bacteria.

And while we’re talking about germs, how about . . .

  • Flushing Habits

Most toothbrushes live in the bathroom, where we also find—the toilet. Every time we flush, invisible bacteria and particles fly through the air. And while that might not make you sick, it’s still pretty gross. Closing the lid before you flush helps keep your family’s toothbrushes—and bathroom—cleaner.

  • Airing? Yes!

Keeping a toothbrush in a dark, wet environment is the perfect way to help bacteria grow. Instead of putting a wet toothbrush in a case, let it air dry standing heads up after use. Give it a shake first for a head start on drying out.

  • Sharing? No

We’re not talking about sharing a brush, which you would never do. We’re talking about sharing space. If your child’s brush touches other brushes in a toothbrush holder, it’s probably sharing germs. Toothbrushes shouldn’t be too close to other toothbrushes, no matter how close you are to the other brush’s owner!

Finally, no matter how well your child takes care of their toothbrush, there comes a time when you should let it go. After three or four months, bristles become frayed and worn out. This means the brush won’t remove plaque as well as it used to. And to be on the safe side, it’s a good idea to replace a brush if your child has been sick.

Keeping your child’s teeth and mouth healthy is one very important way to keep their whole body heathy and happy. Talk to Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes at our Chicago office to learn more about simple habits for healthy teeth!

How safe are dental X-rays?

November 12th, 2025

Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes and our staff rely on digital X-rays to help us diagnose oral conditions and process images at incredibly high speeds. You can also view digital X-rays in real time while we examine your mouth with an intraoral camera and upload the images to a software program. A chairside computer monitor lets you see these images as we refine areas of concern to ensure an accurate diagnosis.

But are dental X-rays safe?

Yes! They emit 80 percent less radiation than exposure-type X-rays and provide detailed images to improve diagnosis and treatment. We can now detect dental problems in their earliest stages without subjecting you to unnecessary radiation. The amount of radiation released by digital X-rays is “negligible,” which means the amount is so small, that it can be safely disregarded.

Safe enough for children and pregnant women, digital X-rays detect microscopic pitting in tooth enamel and other abnormalities in the oral tissues that might have remained undetected with traditional X-rays. When Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes and our staff discover dental caries in their earliest stages, we can initiate treatment measures that will effectively prevent cavity development, tooth decay, and potential tooth loss.

Patient appointment lengths are shortened with digital X-rays as well, because images are immediately viewable and do not require the exposure time associated with old-style X-rays.

How Digital X-Rays Differ from Traditional X-Rays

Instead of using cardboard-contained film, we insert a small sensing device about the size of a pen in your mouth and engage the digital X-ray machine by manually manipulating control buttons. Within seconds, images appear on the monitor that can later be stored in your file or sent to another doctor for further examination.

The increased resolution afforded by digital X-rays means that patients are able to understand the seriousness of their dental issues better, and are more inclined to follow through with procedures recommended by Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes.

Safer, Better and Faster

For detection of cancerous tumors in their early states, digital X-ray technology offers vast improvements over film X-rays because of its cutting-edge image processing capability. Early detection of oral cancer and dental caries is the best way to prevent any type of oral health problem from exceeding the treatable stage.

The Safety of Dental X-Rays

November 5th, 2025

An article was released to the public stating that dental X-rays contribute to a type of brain cancer. After reading an article like this, your first thought may be to avoid dental X-rays, but you may want to hold off on that quick judgment. As with any treatment we offer at Pediatric Dental Health Associates, Ltd, education is your most valuable tool in deciding what is best for you.

How often dental X-rays are taken is based on risk for infection, physical symptoms, and clinical findings. The American Dental Association (ADA) is a governing body over the dental profession. The ADA states, “ . . . healthy adults receive routine mouth X-rays every two to three years. Dental X-rays are recommended every one to two years for children and every 1.5 to three years for teens. Children often require more X-rays than adults because of their developing teeth and jaws and increased likelihood for cavities.”

A "caries risk category" often determines how often dental X-rays are taken. The most recent documented resource to determine a caries risk is Caries Management by Risk Assessment (CAMBRA). This was adopted by the ADA and is used by dental professionals giving interval recommendations for X-rays.

With knowledge of your risk for dental infection, you will be informed by Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes of the interval at which dental X-rays should be taken. You can rest assured that the standards published by the ADA have been researched extensively and are there to protect your personal health and safety.

Dental X-rays are most commonly digital, which significantly reduces exposure. There is more radiation exposure from the sun or in an airplane than in a dental X-ray. It is common practice to use a lead apron with a thyroid collar for protection during X-ray exposure.

Having a cavity means having an active, potentially harmful infection. Diagnosing such infection with minimal exposure through digital dental X-rays at our Chicago office does more good than harm.
