What should I use to clean my baby’s teeth?

December 10th, 2025

You might think babies don’t need to brush their teeth, especially when they don’t have any. But by starting good habits like brushing when your child is young, you can lay the foundation for them to continue those good habits into adulthood.

When do I start?

The best time to start brushing your baby’s teeth is before he or she has any. Develop the habit of wiping your baby’s gums with a wet, soft washcloth or gauze every day. There is no need to use toothpaste, just wrap the gauze or cloth around your finger, moisten it with a little water, and gently rub it over the gums.

This helps your little one get used to brushing while it eliminates bacteria in the mouth that can harm emerging teeth. You don’t need to apply a lot of pressure or even take very long: just a quick, gentle rub over the gums will do it.

What do I use?

When your child’s teeth begin to come in, you will need to switch from a cloth to a baby toothbrush. Find one that has a grip big enough for your hand, but a head that is small enough to maneuver easily in your infant’s mouth.

You don’t need to use any toothpaste until your son or daughter is about a year old. Even then, though, you’ll want to use just a tiny amount: about the size of a grain of rice. When your toddler is about two years old, you can use a pea-sized amount.

By around six years of age, your child will probably rinse and spit without your help. At that point, you may want to introduce a child-friendly fluoride mouthwash.

How do I do it?

Your child probably won’t be able to brush his or her teeth alone until about the age of five or six. This means that you will need to do it. To brush your child’s teeth, gently use the brush over all the teeth and gums, even areas where the teeth have not come in yet.

As your child grows and becomes more independent, you can allow him or her to hold the toothbrush while you guide your child’s progress. Make sure you talk to your child while you are brushing, and explain why you brush: what you are doing and how you are doing it.

In addition to regular visits with Dr. Irwin Seidman, instilling good oral health habits in your child early on will ensure a lifetime of good dental health.

Educational and Entertaining Enamel Experiments

December 3rd, 2025

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!

Smile! It’s Time for Arts & Crafts!

November 26th, 2025

If you have a child who loves arts and crafts, try some of these creative projects with a dental twist. One of these activities is sure to give your child something to smile about!

Toothbrush Art

Why throw away that used toothbrush when you can help your young child make art with it? Give it one more cleaning and a second life. The easy-to-grip handle and the wide bristles make a toothbrush easy for young hands to hold and paint with. If you are in an adventurous mood, use the brush to make splatter art. Your child can splatter an entire sheet of paper for an abstract effect, make a sky full of stars with a flick of the brush, or add splatter leaves to a tree scene. Cut out a stencil with a favorite shape (an animal, a flower, a toy), place it on a sheet of paper, splatter around it, remove the cutout, and—instant silhouette!

Paper Crafts

If your child is an origami enthusiast, there are some challenging dental-themed examples available online. These might be too advanced for beginners, but more experienced origami fans can make molars with roots and even molars lined with pink paper to symbolize the interior pulp. Younger paper artists might enjoy making construction paper models of an actual tooth, with white enamel, yellow dentin, and pink pulp layered in their proper order.

Sculpting Fun

For the scientifically minded young artist, clay can be used to make a 3D model of a tooth, with different colored clays representing the different layers of the tooth. Younger children learning about their teeth might enjoy fitting little white clay teeth into a pink clay crescent to show how baby (or adult) teeth fit into the gums. And for non-dental inspiration, old, clean toothbrushes can once again help out if your child likes sculpting art work with modeling clay. Add interesting texture by using the brush bristles on damp clay to create grooves, lines, or indentations.

Welcome the Tooth Fairy

If the Tooth Fairy is a regular visitor, make her welcome with a box decorated with paint or fabric to hold that special baby tooth. Or craft a pouch or a bag with fabrics scraps, and add a fabric tooth so that the Tooth Fairy will know she has come to the right spot. If you use felt and fabric glue, no sewing necessary! If your Tooth Fairy is an under-the-pillow traditionalist, decorate an envelope with a letter to the Tooth Fairy inside.

If some of these projects sound just right for your child, check out online craft sites for even more ideas. And, please be sure to have your children show and tell the next time they visit our Palatine, IL office. That will put a smile on our faces!

Are thumb sucking and pacifier habits harmful for a child’s teeth?

November 19th, 2025

Depending on how long the thumb sucking or constant pacifier use continues, and how aggressively the child sucks a thumb or the pacifier, it can indeed be an oral health issue. Generally speaking, most children outgrow these behaviors or are able to be weaned off them successfully sometime between ages two and four. When children wean off the behaviors in this age range, long-term damage is unlikely.

Why Kids Suck Their Thumb or Pacifier

Both of these habits are actually a form of self soothing that your child likely uses when he or she is very upset, or feeling stressed, confused, frustrated, or unable to properly express the emotions. If your son or daughters is a regular thumb sucker, or the child wants to use the pacifier almost constantly, it is best to try to taper off these habits at a young age.

If your child continues to suck a thumb or request a pacifier consistently after leaving toddler-hood, this could be a source of concern, and it should be addressed with Dr. Irwin Seidman and our staff. We will be able to evaluate your child's mouth to look for any signs of damage such as palate changes or teeth shifting.

Say Goodbye to Old Habits

In the event that your child is quite reluctant to give up a pacifier or thumb-sucking habit, there are a few things you can do to discourage these behaviors.

  • When you notice that your child is not using a pacifier or sucking a thumb, offer effusive praise. This type of positive reinforcement can be much more effective than scolding the child.
  • Consider instituting a reward system for giving up the habit. If the child goes a certain amount of time without this behavior, award him or her for being such a “big kid.”
  • Employ the help of older siblings or relatives that your child admires. When a child’s role model says that he or she stopped sucking thumbs at a certain age, your child is likely to try to emulate that.
