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.

As adults, we often wish our teeth could be as white as they were when we were small children. Baby teeth have thinner and whiter enamel than adult teeth, and those brilliant smiles are a result! But occasionally, you may be surprised to discover some staining or discoloration on those lovely first teeth. You might be tempted to apply a whitening product to your child’s teeth, but, please—read on!

Causes of Staining

• Improper Brushing—Often, a loss of tooth whiteness means that plaque has built up on the tooth surface. Careful brushing is needed to remove bacteria and plaque, and if your child isn’t brushing at least twice a day for two minutes, discoloration can be the result.
• Medications—When given in liquid form, or when added to formula or food, iron supplements can cause dark grey staining on the teeth. Medications taken by a mother while pregnant or breast feeding, such as tetracycline, can also lead to discoloration.
• Injury—If a tooth suffers a serious injury, the tooth can darken because of changes inside the enamel.
• Health conditions—Certain health problems can cause tooth discoloration, or sometimes children are born with weaker enamel that is more likely to stain.

If you have noticed any staining on your child’s primary teeth, call our Chicago office. Simple stains can often be removed with better brushing techniques, and we can clean other surface stains in the office. Staining caused by an injury or a health condition is something we can discuss in detail with you. We can even use some professional whitening methods if those are indicated.

Why not just buy a home whitening kit for your child? There are several important reasons to leave these products on the shelf while your child is young.

• Whitening kits are designed for adults. They have been tested for adult teeth in adult trials. Check the box for age appropriate use. Most products are not recommended for pre-teen children.
• Remember that thinner enamel we mentioned earlier? Add to that the delicate skin of young children, and it’s sensible to be cautious about using a bleaching agent that can cause mouth and tooth sensitivity even in adults.
• There is no body of evidence available as to the short and long term effects of using these products on children.

If you are concerned about the brightness of your child’s smile, please talk to Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes. We can recommend better ways to brush at home, clean your child’s teeth in the office, or suggest professional methods of whitening if there are physical or psychological reasons that it would be valuable. But while your child is young, those off-the-shelf whitening products can wait a few more years.

Getting a cavity seems like delayed punishment for eating that special dessert every weekend or for the few days you forgot to floss. When you are doing everything right with minimal exception and a cavity is diagnosed, it is discouraging. Knowing how cavities form and what causes them is valuable in knowing how to prevent them. In this blog post, Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes will help you understand cavities!

A cavity is not a one-time event. It is actually a symptom of a disease called caries. Tooth decay is a result of an active infection and condition in the mouth. There are ingredients to this infection, which include bacteria, acid, your tooth, and a food source. The main bacterial culprit is S. Mutans. Bacteria live in a housing structure called biofilm. This offers them protection, food, and an ideal replicating environment.

Biofilm can be healthy if there is a balance of good bacteria. When you have caries, the numbers of “bad” bacteria increase and produce an environment where they thrive and therefore cause tooth decay. A main indicator of this is a pH measurement of your saliva.

Several factors can influence the biofilm pH. Foods and beverages all have different pH levels. The lower the number, the higher the acidity. Since acid promotes tooth decay, a beverage like soda will promote a cavity. Water, being neutral, is a good choice to promote healthy oral pH. Healthy eating can still cause cavities. Here is an example of a highly acidic, yet traditionally healthy meal:

Toast with store-bought strawberry jam, and a cup of cottage cheese topped with fresh cranberries.

Instead, here is a better choice, which involves mixing acidic healthy foods with alkaline (non-acidic) foods to reduce the overall pH:

Toast with almond butter, and Greek yogurt topped with fresh blueberries.

The first example will result in a very low pH in the mouth and even in the rest of the body. The second meal mixes highly acidic blueberries with an alkaline Greek yogurt. Dairy products from cows are highly acidic. Toast is acidic because of the yeast and almonds are alkaline.

A natural buffer is saliva. Whenever mouth breathing or medications compromise the saliva flow, the pH is going to drop and caries can go rampant. Getting a cavity is not just about the sweets or forgotten flossing sessions. It is about the pH levels and bacterial management.

Sometimes the reason for a poor night’s sleep is obvious. Maybe your child watched a scary movie. Or loaded up on sugar before bed. Or can’t get to sleep after a night of computer screens or video games. Not much we can do about these problems.

Sometimes, though, the cause of your child’s sleep difficulties is dental in origin, and that is something Drs. Joanne Oppenheim, Marilia Montero, and Mary J. Hayes can help with.

Teeth grinding, or bruxism, is a very common childhood dental problem. While children with this condition sleep, their jaws clench and their teeth grind against each other throughout the night. When to suspect children might suffer from bruxism? When they experience:

• Frequent headaches or facial pain
• Waking with a sore jaw, or popping or clicking jaw sounds through the day
• Teeth which are chipped, cracked, flattened, worn down, or sensitive
• Waking up tired, because grinding affects the quality of sleep
• Siblings who complain about nocturnal grinding noises, which affect the quality of their

Pain and fatigue are unpleasant enough, but there are additional serious consequences for those who suffer from bruxism. Our jaws are extremely powerful, and clenching and grinding can put hundreds of pounds on pressure on teeth and jaws over a few hours of sleep.

These forces can lead to damaged teeth and dental work, and problems with the temporomandibular joint, or TMJ, the complex hinge that allows our jaws to move up and down, back and forth, and side to side.

Clearly, prevention is clearly a much better option for a healthy smile. And one of the simplest and most effective treatments for preventing the damage caused by bruxism is a night guard.

Night guards fit over the affected teeth to prevent them from touching directly, saving tooth and enamel from injury and wear. Not only do night guards prevent contact, they spread the biting forces of the jaw over the surface of the guard to greatly reduce their impact. And because they also stop the jaw muscles from clenching tightly, there’s no excess stress placed on the temporomandibular joint.

For all these reasons, a night guard is pretty much a slam dunk for adults who grind their teeth. But for children, it’s not necessarily an automatic decision. Why?

• If tooth grinding is mild and appears to be limited to baby teeth, children often outgrow the condition. Your dentist can let you know if you need to do more than monitor the situation.
• Sometimes it seems like your child’s smile changes from day to day. Between losing baby teeth and erupting adult teeth, this beautiful smile is a work in progress. A fitted night guard might not be a perfect fit while your child’s teeth are still coming in and shifting position.
• Finally, jaw and facial pain can also be caused by problems with your child’s bite or misaligned teeth, and that might mean that an orthodontic consultation is in order.

But if you suspect your child is suffering the effects of night time grinding and clenching, give our Chicago office a call. A thorough examination will provide you with the best diagnosis and solutions for helping your child retain a healthy smile and regain a healthy night’s sleep.

And if a night guard is recommended, a dental professional is the best person to see for the most effective night guard.

While over-the-counter products are available, a custom night guard is designed to fit your child’s individual teeth and mouth perfectly. Impressions or 3D scans are taken in the office, and a guard is fabricated with the precise shape, strength, and thickness needed to protect young teeth. And, as a bonus, custom night guards offer the most comfortable fit for the most comfortable night’s sleep.

Scary movies, a late night sugar rush, mesmerizing video screens—not much we can do about those! But if your child is suffering lost sleep and painful mornings because of tooth grinding, give us a call. A night guard just might be the key to sweet dreams.
