Why Are My Child’s Baby Teeth So White?

April 1st, 2026

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 Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes 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 Chicago office. This is the simplest prescription for a charming, white, and healthy smile at any age.

The Importance of Baby Teeth

March 25th, 2026

Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes and our team know it can be easy to underestimate the significance of baby teeth. At Pediatric Dental Health Associates, Ltd, we sometimes meet parents who assume that since their child's baby teeth, also known as primary teeth, eventually fall out and are replaced, they are less important. But did you know baby teeth serve purposes other than biting, chewing, and digesting food properly?

Baby teeth are essential not only for your child’s language development, but they also serve other important functions, like contributing to the normal development of your child’s jaw bones and facial muscles. Baby teeth also reserve space for your child’s future permanent teeth.

So, when do baby teeth fall out?

A baby tooth is intended to remain in your child’s mouth until the permanent tooth underneath it is ready to take its place. Sometimes, either due to a tooth being knocked out accidentally or being removed because of tooth decay, kids lose baby teeth before the permanent teeth are ready to erupt. If a tooth is lost, the teeth on either side of the open space may possibly push into the open space. The result? There may not be enough room for the permanent tooth when it is finally ready to erupt.

If you have any questions about your toddler’s teeth, or if your child is experiencing issues that concern you, please give us a call to set up an appointment at our convenient Chicago office.

Halitosis in Children: Causes and treatment

March 18th, 2026

Halitosis is the scientific name for bad breath. It is one of the most common oral concerns, and it affects a large percentage of the population, including children. Having bad breath can be embarrassing and a nuisance. When considering what to do about halitosis, the team at Pediatric Dental Health Associates, Ltd highlights that you need to focus on the cause, rather than just masking the problem.

Children commonly have bad breath because of an upper respiratory infection. This includes a common cold, postnasal drip, or allergies. When this is the case, treatment may be complicated if one or more of these issues is chronic.

Another cause of halitosis in children is a condition with their teeth or gums. Just as in adults, gum disease has a distinctive malodor. The quality of brushing and flossing in children directly influences the presence of gum disease. If there is a large untreated cavity, there will be a strong smell causing bad breath. Both of these issues need professional attention, including a visit to the dentist.

Tonsillitis can also cause halitosis in children. It happens because of a constricted airway, resulting in mouth breathing. Mouth breathing is a concern because of how much it dries the tissue in the mouth. This makes any bacterial infection in the mouth worse and causes an increased potency within the bacteria in the mouth.

Treatment of halitosis is as varied as the causes listed above. Beware of ingredients in products that mask bad breath. Sucking on a mint on a regular basis will cause more harm than good because of potential decay. Chew sugarless gum and mints.

If you have any other questions, feel free to call us at Pediatric Dental Health Associates, Ltd or ask Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes during your next appointment!

What are dental sealants, who should get them, and how long do they last?

March 11th, 2026

Dental sealants are an excellent way to protect children’s teeth from tooth decay by coating them with a thin plastic material. Their teeth look and feel like normal, but they are protected from plaque build-up and decay early on. Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes and our staff recommend sealants as a preventive measure for children before any decay appears on their teeth.

Who should get dental sealants?

Dental sealants are intended for young children as soon as their first teeth come in. Decay is most common in the molars, so taking your child to Pediatric Dental Health Associates, Ltd for sealants right when you see the molars grow in gives your child the best chance to fight tooth decay.

A child’s first set of permanent molars grow in between ages five and seven, while the second permanent molars come in between 11 and 14 years of age. Some teens and adults who don’t have tooth decay may get sealants as well, but it is less common.

How long do dental sealants last?

Once the sealant has been placed on the teeth, it lasts up to ten years. Expect to have Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes check the sealant at every visit to our Chicago office, which should be twice a year. We will look at the sealant and determine if it needs to be replaced.

What is the process of getting sealants?

Applying sealants is a simple, pain-free procedure that is done quickly at Pediatric Dental Health Associates, Ltd. There is absolutely no effect on the tooth structure from sealants.

For starters, the teeth are cleaned carefully, then dried with an absorbent material. A mild acid solution is applied to them to roughen them slightly. This is done so the sealant can bond properly to the teeth. Then the teeth are rinsed and dried, and the sealant material is painted on and dried with a special light.

Molars are susceptible to decay early on, which is why sealants are an important treatment to get for your children’s first set of teeth.
