One of the most charming aspects of your baby’s beautiful smile is his brilliantly white teeth. But now that his adult teeth are coming in, the difference in color is very noticeable. Is this something to be concerned about? Happily, probably not.

Both baby teeth and adult teeth have the same basic structure. The inside of the tooth, the pulp, contains blood vessels and nerves. The pulp is covered by a layer of dentin, a hard, yellowish substance composed of living tissue that helps protect the pulp and transmits signals for pain, pressure, and temperature. Enamel is the outer protective covering of the tooth, and its natural color can vary from greyish-white to light yellow.

If primary and permanent teeth are so alike, how can they look so different? As with so many things, the difference lies in the details. In adult teeth, enamel is semi-translucent, so it will allow the color of what is beneath it to show through. And the color of the thick dentin beneath is naturally yellow. Baby teeth have a thinner layer of the yellowish dentin. And while their enamel is also thinner, the enamel in baby teeth is generally whiter and more opaque, so less of the underlying yellow from the dentin is visible.

The result of these small differences is that adult teeth are normally darker than baby teeth to begin with. And when a permanent tooth that is just a bit darker erupts next to a bright white baby tooth, it is going to look even more yellow than it actually is. Once all of the baby teeth in front have been replaced with adult teeth, you will have a much better idea of their real color without unflattering comparisons!

There are times when concerns about tooth color should be looked at by Dr. Stephen Korson more closely.

• Unusual discoloration in teeth should be examined. Some discoloration is caused by medical conditions such as hypomineralization, some by environmental factors such as excess fluoride, some by trauma, some by medication. If you notice a discolored section of your child’s tooth, or the tooth has turned a different shade from the teeth around it, give us a call.
• Your child might have naturally whiter or yellower teeth simply as a matter of genetics. If your child is self-conscious about the color of his teeth, we can talk about whitening solutions when he is old enough to use them safely. Home whitening products should never be used on young children.

Give yourself time to adjust to your child’s new, adult smile. You will probably notice no difference at all once all of his permanent teeth come in. And keep those new teeth their brightest with consistent brushing and flossing, and regular checkups and cleanings at our Summit, NJ office. This is the simplest prescription for a charming, white, and healthy smile at any age.

Your darling three-month old is crying and fussy—can she be teething already? Or, your happy baby boy has just celebrated his first birthday—with only one tooth in that beautiful, gummy smile. Is this normal? Probably! While baby teeth do typically erupt (come in) in the same order for all babies, and around the same time, there is still a lot of flexibility in the time it takes for a full, healthy smile to develop.

Baby teeth actually form before your baby is born, and those 20 teeth are there under the gums waiting to come out and shine. And even though there are no firm and fast dates for each of these primary teeth to erupt, it’s helpful to have a general overview of typical teething patterns so you know what to look forward to.

Incisors

These little teeth create a charming baby smile, and, if your finger has been in the wrong place at the wrong time, a very sharp one as well! That is because these tiny incisors are made to bite into foods. You might notice this when you introduce solid foods, even if the majority of your child’s “chewing” is done with her back gums. These teeth are the earliest to arrive.

• Six to ten months old: The lower central incisors (bottom front teeth) are often the first to come in.
• Eight to 12 months old: The upper incisors (8-12 months) are the next to show.
• Nine to 13 months old: The upper lateral incisors on each side of the front teeth arrive.
• Ten to 16 months old: The lower lateral incisors appear.

First Molars

Because these are larger teeth, babies often experience another bout of teething pain at this time. The large flat surface of each molar helps your child to chew and grind food, so he can handle a wider variety of foods and develop his chewing skills.

• 13 to 19 months old: You can generally expect to see the upper first molars arrive.
• 14 to 18 months old: The lower first molars appear.

Canines (Cuspids)

Fitting between the first molars and the incisors, the strong, pointed shape of the canine teeth allows your child to grip food and break it apart more easily.

• 16 to 22 months old: The upper two canines make their way into the space between the incisors and the first molars.
• 17 to 23 months old: The two lower canines appear.

Second Molars

By the age of three, most children have a full set of baby teeth.

• 23 to 31 months old: The second pair of bottom molars start erupting—you are in the home stretch!
• 25 to 33 months old: The upper second molars come in—completing that beautiful set of 20 teeth!

Baby teeth are extremely important, as Dr. Stephen Korson will tell you when you visit our Summit, NJ office. They help your child eat and chew, develop face and jaw muscles, assist proper speech formation, and provide space for the adult teeth to come in properly. Now that your child’s smile is complete, keep providing him with the same care and attention you have been giving those little teeth since the arrival of the very first incisor.

It seems that so much of new parenthood is scheduling—when to feed her, when to put her to bed, how many hours between naps. But we soon find out that every baby is not on the same schedule, and the same is true for the arrival of their teeth. We should see your baby when that first tooth comes in, or by his or her first birthday. And if you ever have concerns at any time about your child’s teething schedule or teething delays, always feel free to give us a call.

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 Summit, NJ office. That will put a smile on our faces!

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!
